Doug is selling his autographed baseball. He bought it for $26 and wants to mark it up 20%. What will the new price be?

We have triangle ABC, the length of side AB is 16 inches and the length of side BC is 24 inches, the possible length of the side AC is less than 40 inches

To find the possible length of side AC, we need to use the triangle inequality theorem, which states that the sum of any two sides of a triangle must be greater than the third side, that is, a + b > c, b + c > a, c + a > b.

Now, for the given triangle ABC:

a = AB = 16 inches

b = BC = 24 inches

c = AC

We know that a + b > c (using the triangle inequality theorem)

16 + 24 > cc < 40

Therefore, By using the triangle inequality theorem, the possible length of the side AC is less than 40 inches.

Step-by-step explanation:

From the plot, we can see that curve B is taller and more narrow than curve A, and it is shifted to the right relative to curve A. This tells us that curve B has a larger mean and smaller standard deviation than curve A. Therefore, statement 2 is true, and statements 1, 3, 5, and 6 are false. Finally, since curve A is more spread out than curve B, it has a larger standard deviation. Therefore, statement 4 is true.

Answer: 24000 g

Step-by-step explanation:

multiply together:

4 bags * 6 kg = 24 kg total

convert:

1 kg = 1000 g

24 kg * (1000 g / 1 kg) = 24000 g

To calculate the total mass of the box in grams, we need to first calculate the total mass of the 4 bags of sugar in kilograms, and then convert that to grams.

The mass of one bag of sugar is 6 kilograms.

The total mass of all 4 bags is:

4 bags x 6 kilograms/bag = 24 kilograms

To convert 24 kilograms to grams, we multiply by the conversion factor of 1000 grams/kilogram:

24 kilograms x 1000 grams/kilogram = 24,000 grams

Therefore, the total mass of the box, including all 4 bags of sugar, is 24,000 grams.

The correct answer is B) 24,000 grams.

The shortest possible distance between Alan and Ryan is 11,250 miles, and the longest possible distance is 12,000 miles

Distance is a numerical measurement of how far apart two objects or points are. It is a scalar quantity, meaning that it has magnitude but no direction. Distance is usually measured in units such as meters, kilometers, miles, or feet, depending on the system of measurement used.

Sound is a type of physical energy that is produced by vibrating objects and travels through a medium, such as air, water, or solids, as a series of pressure waves. When an object vibrates, it creates a disturbance in the surrounding medium that causes molecules to move back and forth, creating areas of high and low pressure that propagate outward from the source of the sound.

In the given question,

Let d be the distance between Alan and Ryan in miles. Then, the time it takes for sound to travel this distance is given by d/768. Therefore, we have:

d/768 = 45 - 30 = 15

Solving for d, we get:

d = 15 x 768 = 11520

So the distance between Alan and Ryan is 11520 miles.

If we take the lower bound of 750 miles per hour, we can calculate the minimum distance between Alan and Ryan as follows:

d/750 = 15

d = 15 x 750 = 11250

Therefore, the minimum distance between Alan and Ryan is 11250 miles.

If we take the upper bound of 800 miles per hour, we can calculate the maximum distance between Alan and Ryan as follows:

d/800 = 15

d = 15 x 800 = 12000

Therefore, the maximum distance between Alan and Ryan is 12000 miles.

Therefore, the shortest possible distance between Alan and Ryan is 11,250 miles, and the longest possible distance is 12,000 miles.

The answer to the question is 334 kittens.

Given that a cat gave birth to 333 kittens who each had a different mass between 147 g and 159 g. Then the cat gave birth to a 4th kitten with a mass of 57 g.

First of all, we will find out the range of the mass of kittens. The range is given as follows;Range = Maximum Value - Minimum Value Range = 159 g - 147 g Range = 12 g

Now, the cat gave birth to a 4th kitten with a mass of 57 g, we can say that the minimum value of kitten's mass is 57 g.So, the maximum value of kitten's mass can be calculated as follows;Maximum Value = 57 g + Range Maximum Value = 57 g + 12 g Maximum Value = 69 g Now, we can say that all kittens with a mass of 69 g or less would be born because the minimum value of kitten's mass is 57 g and the range of mass is 12 g.

0, 2%, 2 1/2 The values are ordered from smallest to largest, with 0 being the smallest, followed by 2%, and then 2 1/2.

0 is the smallest value because it represents nothing. It is the absence of a quantity, and therefore, it is always the smallest value.

2% is larger than 0 because it represents a percentage of a whole. Percentages are fractions out of 100, so 2% means 2 out of 100. It is larger than 0, but smaller than 2 1/2.

2 1/2 is the largest value because it represents a whole number and a fraction. It is larger than 2%, because 2 1/2 is equal to 250 out of 10,000 or 25 out of 1,000, which is a larger quantity than 2 out of 100.

The explicit formula for the arithmetic sequence 12, 5, -2, -9,..is a(n) = -7n + 19.

To find the explicit formula for this arithmetic sequence, we first need to determine the common difference, which is the amount by which each term differs from the previous term.

d = 5 - 12 = -7

d = -2 - 5 = -7

d = -9 - (-2) = -7

Since the common difference is -7, we can use the formula for an arithmetic sequence:

a(n) = a (1) + (n - 1) d

where a(n) is the nth term of the sequence, a (1) is the first term, n is the term number, and d is the common difference.

Plugging in the given values, we get:

a(n) = 12 + (n - 1) (-7)

The probability of randomly selecting a doctor who is either a General Practitioner or under the age of 40 from a small hospital is 9/19, given 6 out of 19 are General Practitioners, 5 out of 19 are under 40, and 2 are both.

To find the probability of randomly selecting a doctor who is either a General Practitioner or under the age of 40, we need to add the probabilities of these two events and subtract the probability of selecting a doctor who is both a General Practitioner and under the age of 40, since we don't want to count that case twice:

P(General Practitioner or under 40) = P(General Practitioner) + P(Under 40) - P(General Practitioner and under 40)

we know 6 out of 19 doctors are General Practitioners, 5 out of 19 doctors are under the age of 40, 2 doctors are both General Practitioners and under the age of 40.

Therefore:

P(General Practitioner) = 6/19

P(Under 40) = 5/19

P(General Practitioner and under 40) = 2/19

Substituting these values into the formula:

P(General Practitioner or under 40) = 6/19 + 5/19 - 2/19

= 9/19

Therefore, the probability of randomly selecting a doctor who is either a General Practitioner or under the age of 40 is 9/19.

Answer:

Step-by-step explanation:

the equivalent closed form for the original rate function is

.[tex]S π/t 4tan (t) dt  = -4 ln |cos (t)| + C.[/tex]

a. [tex]S π / π /4 5t+4 / t² + 1 dt[/tex]We can write this rate function as a sum of two functions by expanding the denominator:

[tex]S π / π /4 5t+4 / (t² + 1) dt  = S π / π /4 5t+4 / (t² + 1) (t+1/t - 1/t) dt  = S π / π /4 5t+4 (t+1 - 1/t²) dt  = S π / π /4 5t+4 (t+1) dt - S π / π /4 5t+4 (1/t²) dt[/tex]

Now, integrating the two functions gives us the closed form:

[tex]S π / π /4 5t+4 (t+1) dt = 5/2 (t² + 2t + 2) + CS π / π /4 5t+4 (1/t²) dt = -5/2 (t + 1/t) + C[/tex]

Therefore, the equivalent closed form for the original rate function isS π / π /4 5t+4 / t² + 1 dt  = 5/2 (t² + 2t + 2) - 5/2 (t + 1/t) + C.

b. S π/t 4tan (t) dt
We can use a trig identity to change the form of this rate function:

S π/t 4tan (t) dt  = S π/t 4 (sin (t) / cos (t)) dt  = 4/cos (t) S π/t sin (t) dt

Integrating the rate function gives us the closed form:

S π/t 4tan (t) dt  = 4/cos (t) S π/t sin (t) dt = -4 ln |cos (t)| + C.

The coordinates of R are (-8,-1). To find the coordinates of R, we first need to find the length of PQ.

Using the distance formula, we have:

d(P,Q) = √((x2-x1)² + (y2-y1)²)

= √((-4-(-12))² + (-9-7)²)

= √(8² + (-16)²)

= √(320)

= 8 √(5)

Since PR:QR is 3:5, we can set up the following equation:

d(P,R)/d(R,Q) = 3/5

Let the coordinates of R be (x,y). We can use the midpoint formula to find the coordinates of the midpoint of PQ, which is also the coordinates of the point that divides PQ into two parts in the ratio of 3:5.

Midpoint of PQ = ((-12-4)/2, (7-9)/2) = (-8,-1)

Using the distance formula again, we can find the distance between P and R:

d(P,R) = (3/8) d(P,Q)

= (3/8) (8 √(5))

= 3 √(5)

Now we can use the ratio PR:QR = 3:5 to find the distance between R and Q:

d(R,Q) = (5/3) d(P,R)

= (5/3) (3 √(5))

= 5 √(5)

Finally, we can use the midpoint formula to find the coordinates of R:

a) The constant k is 5.427 x 10^−12 and its natural logarithm is -26.68.

b) The mean salary of the given model by using the probability density function is approximately $270.86.

a) The cumulative distribution function of the given random variable is provided as follows:

F(x) = {1−kx^−3 if x>44000, and 0 otherwise

The cumulative distribution function is given as

F(x) = 1−kx^−3 if x>44000 and F(x) = 0, if x≤44000i)

We need to check the value of the cumulative distribution function at 44000

We have, F(44000) = 0

0 = 1−k(44000)^−3

⇒ 1 = k(44000)^−3

⇒ k = 1/(44000)^−3

⇒ 5.427 x 10^−12

Taking the natural logarithm of k, we have ln(k) = −28.68 (approx.)

Hence, the constant k is 5.427 x 10^−12 and its natural logarithm to three decimal places is -28.68

b) The probability density function is given as,

f(x) = F'(x) = 3kx^−4, for x>44000 and f(x) = 0, otherwise
