If f(x)= 2x/7+4 which of the following is the inverse of f(x)

Answers

The inverse of the function f(x)= 2x/7 + 4 is y = 7x/2 - 14.

What is the inverse of the function?

Given the function; f(x)= 2x/7 + 4

First. we write the function as an equation then interchange the variables.

y = 2x/7 + 4

x = 2y/7 + 4

We solve for y.

2y/7 = x - 4

2y = 7x - 28

y = 7x/2 - 28/2

y = 7x/2 - 14

Therefore, the inverse of the function f(x)= 2x/7 + 4 is y = 7x/2 - 14.

The length of a rectangle is 4 times the width. If the perimeter is to be less than or equal to 100 meters. What are the possible values for the width

Answers

The possible values for the width is w≥10.

Given that the length of a rectangle is 4 times the width and perimeter is to be less than or equal to 100 meters.

The perimeter of a rectangle is the total distance of its four outer boundaries. The perimeter of the object is twice the length and width of the object. This calculation is made using the formula:

perimeter = 2(length + width).

Here Perimeter=100 and length=4w

Substituting these values in the formula to find width, and we get

100≤2(4w+w)

100≤2(5w)

Divide both sides by 2, and we get

100/2≤(2(5w))/2

50≤5w

Divide both sides by 5, and we get

50/5≤5w/5

10≤w

Hence, the possible value for width when the length of a rectangle is 4 times the width is w≥10.

Mario is 63 years older than his grandson Jonas. How many years ago was Mario's age 10 times Jonas's age if Mario's age is currently four times Jonas's age?

Answers

Answer:

14 years ago

Explanation:

Let Mario's age be m, Jonas age be j.

From, Mario is 63 years older than Jonas

Equation 1: m = j + 63

From, Mario's age is four times Jonas age

Equation 2: m = 4j

Solve them by substitution:

m = j + 63

4j = j + 63

4j - j = 63

3j = 63

j = 21

Find Mario's age:

m = j + 63

m = 21 + 63

m = 84

Follow this steps:

m - y = 10(j - y)

84 - y = 10(21 - y)

84 - y = 210 - 10y

-y + 10y = 210 - 84

9y = 126

y = 14

The answer is 14 years ago.

Let Mario's age be M, and Jonas' age be J.

The formed equations :

M = J + 63M = 4J

To find their current ages, substitute the 2nd equation in the 1st equation.

4J = J + 63

3J = 63

J = 21

M = 4(21)

M = 84

For Mario to be 10 times Jonas' age, he has to be an age that is a multiple of 10.

Case (1) : Mario's age = 80

Subtract 4 from both their ages.

Mario : 84 - 4 = 80

Jonas : 21 - 4 = 17

17 × 10 ≠ 80

Case (2) : Mario's age = 70

Subtract 14 from both their ages.

Mario : 84 - 14 = 70

Jonas : 21 - 14 = 7

7 × 10 = 70

Out of 2000 pizzas he sells next time he should expect 797 stuffed crust or pan style. This can be obtained by using formula of probability and multiplying the total number of pizzas.

Find the expected value:

The formula for Expected value:

EV = P(X) × n

where EV is the expected value and P(X) is the probability of X and n is the total number.

     

In the question it is given that,

Thin crust ⇒ number of thin crust sold  = 307 Thick crust ⇒ number of thick crust sold  = 224Stuffed crust ⇒ number of stuffed crust sold  = 161Pan style ⇒ number of pan style sold  = 191

First we have to find the probability of stuffed crust or pan style,

P( stuffed crust or pan style) = P(stuffed crust) + P(pan style)

                                           

The number of stuffed crust and pan style = 161 + 191 = 352

The total number of crusts sold are ⇒ 307 + 224 + 161 + 191 = 883

⇒ P( stuffed crust or pan style) = 161/883 + 191/883

                                                   = 352/883

The expected value of stuffed crust or pan style,

n = 2000, P(X) = 352/883

EV = P(X) × n = (352/883) × 2000 = 797.28 ≈ 797

Hence out of 2000 pizzas he sells next time he should expect 797 stuffed crust or pan style.

M+W+C = 65

----

M+W+C = 65

M+1.5C+C = 65

35+1.5C+C = 65

2.5C = 30

C = 12

An aircraft seam requires 21 rivets. The seam will have to be reworked if any of these rivets is defective. Suppose rivets are defective independently of one another, each with the same probability. (Round your answers to four decimal places.) (a) If 23% of all seams need reworking, what is the probability that a rivet is defective

Answers

For Part A the probability is 0.0095 and for Part B the probability is

0.0043.

What does defective mean in probability?

Probability of defect is perhaps the most important indicator of a manufacturing process's quality. It's a statistical technique used to indicate how often a product will fail during its lifespan, which in turn allows you to estimate the likelihood that an item will result in customer dissatisfaction.

Part A:

The number of rivets=22 rivets

Probability that no rivet is defective= [tex](1-p)^{22}[/tex]

The probability that at least one rivet is defective=1-[tex](1-p)^{22}[/tex]

For 19% of all seams need reworking, probability that a rivet is defective is given by

1-[tex](1-p)^{22}[/tex] = 0.19

[tex](1-p)^{22} = 1-0.19\\(1-p)^{22} = 0.81\\ p=1-\sqrt[22]{0.81} \\p=0.0095[/tex]

Part B:

For 9% of all seams need reworking, probability of a defective rivet is:

1-[tex](1-p)^{22}[/tex] = 0.09

[tex](1-p)^{22} = 1-0.09\\(1-p)^{22} = 0.91\\ p=1-\sqrt[22]{0.91} \\p=0.0043[/tex]

Hence, For Part A the probability is 0.0095 and for Part B the probability is 0.0043.

Describe the difference between plots that show a strong correlation and plots that show a weak correlation.

Answers

We need to find the difference between plots that show a strong correlation and plots that show a weak correlation.

The point of creating a scatter plot is to determine if there is a correlation. Correlation means the relationship between two quantities. For example, there is a correlation between how much a person studies and the grade they get on a test, but there is no correlation between how much money a person earns and what pets they own. In mathematics, correlation between data means that the points follow a pattern and go in the same direction. There are two types of correlation:

Positive: the trend is rising from left to right

Negative: the trend is decreasing from left to right

If the dots on the scatter plot do not follow a pattern, there is no correlation.

All correlations have two properties: strength and direction. The strength of the correlation is determined by its numerical value. The direction of the correlation is determined by whether the correlation is positive or negative.

The strength of the correlation indicates how strong the relationship is between the two variables. The strength is determined by the numerical value of the correlation. A correlation of 1, whether +1 or -1, is a perfect correlation. In perfect correlations, the data points lie directly on the fit line. The further the data is from the fit line, the weaker the correlation. A correlation of 0 means there is no correlation

If the value of correlation coefficient is nearer to to 1 or -1 , then there exist a strong correlation.

If the value of correlation coefficient is nearer to to 0 , then there exist a weak correlation.

#SPJ1

The data points are a little closer for a weak correlation, and you can see that there is some sort of relationship between these factors.

Data points for a strong correlation are in close proximity to one another, making it possible to build a line by imitating their pattern.

A statistic called correlation gauges how much two variables change in connection to one another.

Correlation and diversification, the idea that certain types of risk can be reduced by investing in assets that are not connected, are closely related concepts.

Correlation cannot determine whether x causes y or vice versa, or whether a third component is responsible for the association.

A scatter plot may make it easier to spot correlation, particularly when the variables have a non-linear but nevertheless significant association.

[tex]\sqrt{\frac{15}{2} }[/tex] or 2.738

Step-by-step explanation:

Let’s just look at the triangle on the top with the [tex]\sqrt{10}[/tex] on the top and x on the bottom. (Basically the top half to the equilateral triangle)

There is a small square in the bottom right corner, which indicates that this triangle is a right triangle. This means that we can use the Pythagorean Theorem: [tex]a^{2} +b^{2} =c^{2}[/tex]

We know that \sqrt{10} is our hypotenuse, and therefore our c in our equation. Let’s say that x=a in our equation. Therefore we are left to find b. However, b is half the length of the side of the original equilateral triangle. An equilateral triangle means that all three sides are the same length. Therefore our side would also be \sqrt{10} units long. However we know that b is half of that value, so b=[tex]\frac{1}{2}(\sqrt{10})[/tex] or [tex]\frac{\sqrt{10} }{2}[/tex]

Plugging these values into the equation:

x^2+ (\frac{\sqrt{10} }{2})^{2}=\sqrt{10} ^{2}

[tex]x^{2}=\sqrt{10} ^{2}-\frac{\sqrt{10} }{2} ^{2}[/tex]

[tex]x^{2} =10-\frac{10}{4}[/tex]

[tex]x^{2} =\frac{15}{2}[/tex]

[tex]x=\sqrt{\frac{15}{2} }[/tex]

This approximately equals 2.738

Answer:

[tex]x=\sqrt{\frac{15}{2} }[/tex]. Another form of this answer is [tex]x=\frac{\sqrt{15} }{\sqrt{2} }[/tex](it's the same thing)

Step-by-step explanation:

Because the triangle is equilateral, all other sides of the triangle are also [tex]\sqrt{10}[/tex]. Also, x is the altitude of this triangle as it forms a right angle with the base and is therefore perpendicular. We know that this triangle is equilateral and in any triangle that has at least two sides that are equal(in other words isosceles), the altitude is also the median and angle bisector. A median would cut the side it reaches into half. So, x would cut the base into two equal parts. Since the base is [tex]\sqrt{10}[/tex], divide it by two and both halves are [tex]\frac{\sqrt{10}}{2}[/tex]. What we are left with is two right triangles, both with legs [tex]\frac{\sqrt{10} }{2}[/tex] and x. Using the Pythagorean Theorem, we know that [tex]a^{2}+b^{2}=c^{2}[/tex], with [tex]a[/tex] and [tex]b[/tex] being the legs and [tex]c[/tex] being the hypotenuse. So, we plug in the values and get [tex]\frac{\sqrt{10} }{2} ^{2}[/tex][tex]+x^{2}=\sqrt{10}^{2}[/tex]. Squaring, we get [tex]\frac{10}{4}+x^{2}=10[/tex]. This becomes [tex]x^{2}=10-\frac{10}{4}[/tex] which equals [tex]x^{2}=\frac{40}{4}-\frac{10}{4}[/tex]. Finally, [tex]x^{2}=\frac{30}{4}[/tex]. This is [tex]x^{2}=\frac{15}{2}[/tex]. Square rooting this we get [tex]x=\sqrt{\frac{15}{2} }[/tex]. Another form of this answer is [tex]x=\frac{\sqrt{15} }{\sqrt{2} }[/tex]

Which equation represents exponential decay? * a y=3^x-4 b y=2(4)^x c y=1/2(3)^x d: y=6(1/3)^x

Answers

The equation which represents exponential decay is y=[tex]6(1/3)^{x}[/tex]

Given four equations : 1)y=[tex]3^{x} -4[/tex], 2) y=[tex]2(4)^{x}[/tex], 3) y=[tex]3^{x}/2[/tex], 4) y=[tex]6(1/3)^{x}[/tex].

Equation is relationship between two or more variables expressed in equal to form. Equations of two variables look like ax+by=c. Exponential equation look like [tex]a^{x}[/tex].

Decay means when x value increases ,the y value decreases.

We haveto put 3 values for x in the equations to check.

1)y=[tex]3^{x} -4[/tex]

put x=0,y=-3

put x=1, y=-1

put x=2, y=5

No,itdoes not represents exponential decay.

2) y=2[tex]4^{x}[/tex]

put x=0,y=2

put x=1, y=8

put x=2, y=32

No,it does not represents exponential decay.

3) y=[tex]3^{x}/2[/tex]

put x=0,y=0.5

put x=1, y=1.5

put x=2, y=4.5

No,it does not represents exponential decay.

4)y=6[tex](1/3)^{x}[/tex]

put x=0,y=6

put x=1, y=2

put x=2, y=0.67

Yes ,it represents exponential decay.

Hence the equation which represents exponential decay is y=6[tex](1/3)^{x}[/tex].
