-14+7m <7h, please answer this I need help

Answers

Each pair of numbers (m, h) which meet the inequality is the answer to the inequality. m < h plus 2.

Pairs of numbers: what are they?

A factor pair is a collection of two factors that, when multiplied together, produce a certain result in mathematics. In those other words, it's a pair of integers that we multiply to produce a result. For instance, the factor pair that yields the result in the multiplication formula 6 7 = 42 is composed of the numbers 6 and 7. 42

By adding 14 to both sides, starting with -14 + 7m 7h, we may simplify the left side:

-14 + 7m plus 14 < 7h plus 14

Even more condensed, we get at:

7m < 7h plus 14

The inequality can then be divided by 7 on both sides: m h + 2.

Plot the points A(3,1), B(-2, 6), C(6, 4) on
the coordinate axes below. State the
coordinates of point D such that A, B, C,
and D would form a parallelogram.
(Plotting point D is optional.)

Answers

To form a parallelogram, the opposite sides of the quadrilateral should be parallel. Let's find the coordinates of point D such that AB is parallel to DC.

The slope of line AB = (yB - yA) / (xB - xA) = (6 - 1) / (-2 - 3) = -1

Therefore, the slope of line DC should also be -1.

Let's assume the x-coordinate of point D is xD.

The slope of line CD = (yD - yC) / (xD - xC)

Since the slope of CD is -1, we can write:

(yD - yC) / (xD - xC) = -1

yD - yC = -(xD - xC)

yD = -(xD - xC) + yC

Substituting the coordinates of points C and A, we get:

yD = -(xD - 6) + 4

yD = -xD + 10

Therefore, the coordinates of point D are (xD, -xD + 10).

To find the x-coordinate of point D, we can use the fact that BC is parallel to AD.

The slope of line BC = (yC - yB) / (xC - xB) = (4 - 6) / (6 + 2) = -1/4

Therefore, the slope of line AD should also be -1/4.

The slope of line AD = (yD - yA) / (xD - xA)

Substituting the coordinates of points A and D, we get:

(yD - 1) / (xD - 3) = -1/4

yD - 1 = -(xD - 3) / 4

yD = -(xD - 3) / 4 + 1

yD = -xD/4 + 5/4

Substituting the equation we found for yD in terms of xD, we get:

-xD/4 + 5/4 = -xD + 10

3/4 xD = 35/4

xD = 35/3

Therefore, the coordinates of point D are (35/3, -35/3 + 10) = (35/3, 5/3).

We can now plot the points A, B, C, and D on the coordinate axes, and verify that they form a parallelogram.

A boy who is 3 feet tall can cast a shadow on the ground that is 7 feet long. How tall is a man who can cast a shadow that is 14 feet long?​

Answers

Answer:

Step-by-step explanation:

We can set up a proportion to solve this problem:

(height of boy) / (length of boy's shadow) = (height of man) / (length of man's shadow)

We are given that the boy is 3 feet tall and his shadow is 7 feet long. Let's use "h" to represent the height of the man. We are also given that the man's shadow is 14 feet long. Substituting these values into the proportion, we get:

3/7 = h/14

To solve for h, we can cross-multiply and simplify:

3 × 14 = 7h

42 = 7h

h = 42/7

h = 6

Therefore, the man is 6 feet tall.

Sarun is thrice as old as his sister Anita. If five years is subtracted (5) from Anita’s age and seven years added to Sarun’s age , then
Sarun will be five times Anita’s age. How old were they three years ago?

Answers

Answer: Let's start by using algebra to represent the given information.

If we let "a" be Anita's current age, then we know that Sarun's current age is 3a (since he is thrice as old as Anita).

According to the problem, if we subtract 5 years from Anita's age and add 7 years to Sarun's age, then Sarun will be 5 times Anita's age. In other words, we have the equation:

3a + 7 = 5(a - 5)

Simplifying and solving for a, we get:

3a + 7 = 5a - 25

32 = 2a

a = 16

So Anita is currently 16 years old, and Sarun is 3 times as old, or 48 years old.

To find out how old they were three years ago, we simply subtract 3 from their current ages:

Anita was 13 years old three years ago (16 - 3), and Sarun was 45 years old (48 - 3).

As a result, Lara made a $6,262.71 initial deposit into her savings account.

How long will it take for your money to double if the interest rate is 12% annually compounded?

A credit card user who pays 12% interest (or any other loan type that charges compound interest) will double their debt in six years. The rule can also be applied to determine how long it takes for inflation to cause money's value to decrease by half.

To calculate the initial investment, we can apply the continuous compounding formula:

A = Pe(rt)

Where:

A = the current balance ($7,000.00)

P = the initial deposit (unknown)

r = the annual interest rate (11% or 0.11 as a decimal)

t = the time in years (1 year)

Plugging in these values, we get:

$7,000.00 = Pe(0.11 * 1)

A shorter version of the exponential expression:

$7,000.00 = Pe0.11

$7,000.00 = P * 1.1166 (rounded to 4 decimal places)

In Drosophila, the allele for normal-length wings is dominant over the allele for vestigial wings. In a population of 1,000 individuals, 360 show the recessive phenotype. How many individuals would you expect to be homozygous dominant and heterozygous for this trait?1:2:1 :1:2:1 is the expected genotypic ratio in the progeny derived from a cross involving two heterozygotes of the same gene. The first "1" represents the proportion of dominant homozygotes, the second class, or class "2", the heterozygotes, and the second "1" the recessive homozygotes. This also means that the phenotypic ratio should be 3 dominant phenotype:1 recessive phenotype. From the phenotypic class "3", 2/3 are represented by the heterozygotes, while the remaining 1/3 by the dominant homozygotes.

Answers

The number of individuals who are homozygous dominant (VV) is 160 individuals, and the number of individuals who are heterozygous (Vv) is 320 individuals.

The population of Drosophila has 1000 individuals, 360 of which display the recessive phenotype. Homozygous dominant and heterozygous for this trait in Drosophila would be expected to be found in how many individuals?

In Drosophila, the dominant allele for normal-length wings is denoted as 'V' and the recessive allele for vestigial wings is denoted as 'v.'To determine the number of individuals who are homozygous dominant or heterozygous for this trait, we'll first determine the number of individuals who are homozygous recessive:

Homozygous recessive individuals in the population = number of individuals displaying the recessive phenotype = 360

This indicate that there are 360 individuals with the genotype vv (homozygous recessive), which will be used to determine the remaining genotypes via the Punnett square. To get the number of individuals who are heterozygous (Vv), we first need to identify the number of individuals with the dominant V allele (VV and Vv). The sum of these two genotypes equals the total number of individuals minus the homozygous recessive individuals, as follows:

Total number of individuals - homozygous recessive individuals = (VV + Vv) individuals+ (vv) individuals = 1000 individuals

Hence, VV + Vv = 1000 - 360 = 640 individuals.Now that we know VV + Vv = 640, we can use the expected genotypic ratio of 1:2:1 to calculate the number of homozygous dominant (VV) and heterozygous (Vv) individuals.1:2:1 represents the expected genotypic ratio in the progeny derived from a cross involving two heterozygotes of the same gene. The first "1" represents the proportion of dominant homozygotes, the second class, or class "2", the heterozygotes, and the second "1" the recessive homozygotes.

Therefore, homozygous dominant (VV) and heterozygous (Vv) individuals in the population would be expected in the following ratio:VV:Vv:vv = 1:2:1. Therefore, the number of individuals who are homozygous dominant (VV) is 1/4 of the total individuals (VV + Vv + vv):

Number of individuals who are homozygous dominant (VV) = 1/4 (VV + Vv + vv)= 1/4 (640) = 160 individuals

And the number of individuals who are heterozygous (Vv) is 2/4 of the total individuals (VV + Vv + vv):

Number of individuals who are heterozygous (Vv) = 2/4 (VV + Vv + vv)= 2/4 (640) = 320 individuals

Therefore, the number of individuals who are homozygous dominant (VV) is 160 individuals, and the number of individuals who are heterozygous (Vv) is 320 individuals.

Answers

In the equation A’ = 364V relating the surface area A and the volume V of a spherical balloon. We are also given that the volume is increasing at a rate of 18 cubic inches per second.so the rate at which the surface area of the balloon is increasing is 6552 square inches per second

We want to find the rate at which the surface area is increasing when A = 153.24 square inches and V = 178.37 cubic inches.

To find the rate of change of A with respect to time, we can use the chain rule of differentiation:

dA/dt = dA/dV × dV/dt

We know that dV/dt = 18 cubic inches per second, so we just need to find dA/dV and then we can find dA/dt.

To find dA/dV, we differentiate the equation A’ = 364V with respect to volume V:

dA/dV = 364

Now we can find dA/dt:

dA/dt = dA/dV × dV/dt ⇒ 364 × 18 ⇒ 6552 square inches per second

Prove that the angle bisector of the the angle opposite the base of an isosceles triangle is also the following:

A) the altitude to the base

B) the median to the base

(MUST BE A CORRECT EXPLANATION)

Answers

Answer:

We need to prove that the angle bisector of the angle opposite the base of an isosceles triangle is also the median and altitude to the base.

Let's consider an isosceles triangle ABC where AB = AC. We draw the altitude from A to BC and call the point where it intersects BC as D.

Now, we need to prove that AD is the angle bisector, median, and altitude to the base BC.

To prove AD is the angle bisector:

We need to prove that the angle ADB and ADC are equal. We know that angle ABD and angle ACD are right angles because BD and CD are altitudes. We also know that AB = AC because the triangle is isosceles. Therefore, the triangles ABD and ACD are congruent by the hypotenuse-leg (HL) criterion.

Thus, angle ADB = angle ADC, which means that AD is the angle bisector of angle BAC.

To prove AD is the median:

We need to prove that BD = CD. Since AB = AC and AD is perpendicular to BC, triangles ABD and ACD are congruent by the hypotenuse-leg (HL) criterion. Therefore, BD = CD, which means that AD is also the median to the base.

To prove AD is the altitude:

We need to prove that angle BAD and angle CAD are right angles. This is true because AD is perpendicular to BC, and BD and CD are also perpendicular to BC. Therefore, AD is also the altitude to the base BC.

Hence, we have proved that the angle bisector of the angle opposite the base of an isosceles triangle is also the median and altitude to the base.

Answers

A sampling distribution is normal only if the population is normal. This  statement is false because A sampling distribution is normal only if n≥30.

If the underlying population is normally distributed, the sampling distribution (such as the sample mean distribution, also known as the xbar distribution) is also normally distributed. Even though the population is not normally distributed, the x(bar) distribution is approximately normal if n > 30, due to the central limit theorem. Some textbooks may use values ​​above 30, but after a certain threshold the x(bar) distribution is effectively "normal".

Option B is close, but misses the normal population part. n > 30 is not necessary if we know the population is normal.

A sampling distribution is the probability distribution of a statistic obtained from a large number of samples drawn from a particular population. The sampling distribution for a given population is the frequency distribution of a range of different outcomes that can occur in the population.

In statistics, a population is the entire basin from which a statistical sample is drawn. A population can refer to an entire population of people, objects, events, hospital visits, or measurements.

Answers

The probability of a printer failure given hardware problems is 0.9, given software problems are 0.2, and given any other type of problem is 0.5. The customer should diagnose the printer failure by looking for a hardware issue.

The probability of printer failure is dependent on three problem types, hardware, software, and others (like connectors). The respective probabilities are 0.1_, 0.6, and 0.3_.

We have hardware problems, the probability of printer failure is 0.9, given software problems the probability is 0.2, and given any other problem type the probability is 0.5. By using Bayes' theorem, the most probable cause of the failure can be determined.

Let A represent the cause of the problem, and B is the evidence that the customer sees. Let's calculate the probability that A = hardware given B, which is P(A|B) = P(B|A)*P(A)/P(B).

Here, P(A) is the prior probability of the cause being hardware,

P(B|A) is the likelihood of observing the evidence given the cause being hardware, and P(B) is the probability of observing the evidence.

Given hardware problems, the probability of printer failure is 0.9, while the probability of observing this evidence given hardware problems is 0.9. Since there are three problem types, each of them having a prior probability of 1/3, we get P(A) = 1/3.

The probabilities of observing the evidence in the case of other types of problems and software problems are 0.5 and 0.2, respectively. Therefore, the most likely cause of printer failure is hardware problems.

A square field has a side length of 6x10³ meters. Which of the following is its area in square meter
(1) 6x106
(3) 36x106
(2) 36×10⁹
(4) 6x10⁹

Answers

Answer:

36 × 10^6 m²

Step-by-step explanation:

Given the side length of a square = 6 × 10³m,

To solve for the area of a square, use the following formula:

A = S² where:

S = side of the square

Substitute the given value for the side into the formula:

A = S²

A = (6 × 10³)²

A = 36000000 or 36 × 10^6 m²

NOTE:

6 × 10³ is also the same as 6 × 1000 = 6000,

(6 × 10³)² is essentially 6,000² = 36,000,000

Therefore, its area in square meters is 36 × 10^6

Noise-canceling headphones have microphones to detect the ambient, or background, noise. They interpret those noises as sinusoidal functions. To cancel out that noise, the headphones create their own sinusoidal functions that mimic the incoming noise, but it changes them in one of two ways.
1. The mimic function is the negative of the noise's function.
2. The mimic function is the noise function shifted one-half period.

The headphones then play the noise function together with the mimic function, which cancels the noise.

Instructions
• Find the frequency of any musical note in hertz (Hz).
• Use the frequency to write f(x), the sine function for the note. For example, [tex]A_4[/tex] has a frequency of 440 Hz. In radians, we describe this note as y = sin(440(2πx)) or y − sin(880πx)
• Graph the sine function for the chosen note.
• Use one of the two methods listed above to write g(x), the mimic function that cancels that note's sound. Graph that function.
• Write a third function, h(x), that is the sum of f(x) and g(x). Graph it.
• Use your three graphs to explain why g(x) cancels out f(x).

Answers

Let's assume we want to cancel out a musical note with a frequency of f Hz. We can write the sine function for this note as:

f(x) = sin(2πfx)

To cancel out this note, we need to create a mimic function g(x) that is either the negative of f(x) or shifted one-half period. Let's consider the two cases separately:

1. Mimic function is the negative of f(x):

In this case, the mimic function g(x) is simply the negative of f(x):

g(x) = - sin(2πfx)

We can graph f(x) and g(x) together to see how they cancel each other out:

Graph of f(x) and g(x) when g(x) is the negative of f(x):

The blue graph represents f(x), while the red graph represents g(x). As we can see, the two functions are equal in magnitude but opposite in sign. When we add them together, we get:

h(x) = f(x) + g(x) = sin(2πfx) - sin(2πfx) = 0

This means that the sound of the musical note is cancelled out completely.

2. Mimic function is the noise function shifted one-half period:

In this case, the mimic function g(x) is the sine function with the same frequency as f(x), but shifted one-half period:

g(x) = sin(2πfx + π)

We can graph f(x) and g(x) together to see how they cancel each other out:

Graph of f(x) and g(x) when g(x) is the noise function shifted one-half period:

The blue graph represents f(x), while the red graph represents g(x). As we can see, the two functions are equal in magnitude but out of phase by one-half period. When we add them together, we get:

h(x) = f(x) + g(x) = sin(2πfx) + sin(2πfx + π)

Using trigonometric identities, we can simplify this expression to:

h(x) = 2cos(π/2)sin(2πfx + π/2)

h(x) = 2cos(π/2)cos(2πfx) (since sin(2πfx + π/2) = cos(2πfx))

h(x) = 2sin(2πfx)

This means that the sound of the musical note is cancelled out completely.

In summary, the mimic function g(x) cancels out the sound of the musical note by either being the negative of the noise function or being the noise function shifted one-half period. In both cases, the mimic function has the same frequency as the noise function, but is equal in magnitude and opposite in sign or out of phase by one-half period. When we add the noise function and the mimic function together, they cancel each other out and we are left with no sound.

During one season of racing at the Talladega Superspeedway, the mean speed of the cars racing there was found to be 158.9 mph with a standard deviation of 6.7 mph. What speed represents the 30th percentile for speeds of race cars at Talladega? Assume that the racing speeds are normally distributed.

Answers

Solution:Given, the mean speed of the cars racing = 158.9 mph standard deviation = 6.7 mph

To find:What speed represents the 30th percentile for speeds of race cars at Talladega?

We need to find the z-score for the 30th percentile.From the standard normal distribution table, the z-score for the 30th percentile is -0.52.Using the formula for z-score we havez=(x-μ)/σwhere x is the speed of the carsμ is the mean speed = 158.9σ is the standard deviation = 6.7Substituting these values in the above equation we have-0.52=(x-158.9)/6.7Rearranging we get,x - 158.9 =[tex]-0.52 × 6.7x - 158.9 = -3.524x = 158.9 - 3.524x = 155.376[/tex]The speed that represents the 30th percentile for speeds of race cars at Talladega is approximately 155.38 mph.

How to calculate the probability?

In a multiple choice exam, there are 5 questions and 4 choices for each question (a, b, c, d). Nancy has not studied for the exam at all and decides to randomly guess the answers.

The probability of guessing on an exam can be calculated by using the formula:n(C)/(n(T))where n(C) is the number of favorable events and n(T) is the total number of events. Let's solve the given problem:

Probability of getting the first question correct: P (1st) = 1/4 Probability of getting the second question correct: P (2nd) = 1/4Probability of getting the third question correct: P (3rd) = 1/4 Probability of getting the fourth question correct: P (4th) = 1/4Probability of getting the fifth question correct: P (5th) = 1/4 The probability of guessing all questions correctly can be calculated by multiplying the probability of each question together. P (all) = P (1st) * P (2nd) * P (3rd) * P (4th) * P (5th)= 1/4 * 1/4 * 1/4 * 1/4 * 1/4= 1/1024Therefore, the probability that Nancy will correctly answer all 5 questions by guessing is 0.000977.
