Answer:

3/12 players are defensive

Step-by-step explanation:

have to change demonitar to 12 so 3x4=12 so 2x4= 8

then 8+1=9 so 9/12

then 9-12=3 so 3/12 is the amount of defensive players

What are the coordinates of the image of vertex R after a
reflection across the y-axis?
O (4,3)
O (4, -3)
0 (-3,-4)
O (3, 4)

Answers

Answer:

Step-by-step explanation:

The coordinates of the image of vertex R after a reflection across the y-axis is (4,-3), the correct option is B.

What is a reflection?

A reflection can be defined as a type of transformation which moves every point of the object by producing a flipped but mirror image of the geometric figure. Consider a plane. Consider a design or shape on that plane. Now consider an axis.

If we think of that axis as a mirror, and on the opposite side of that axis create the image of the considered shape, then if the shape's image looks exactly as the shape itself, then that shape is called to have a reflectional symmetry.

We are given that;

The vertex R=(-4,-3)

Now,

When reflecting a point across the y-axis, the x-coordinate changes its sign, while the y-coordinate remains the same. Therefore, the image of vertex R(-4,-3) after reflection across the y-axis would be the point (4,-3), since its x-coordinate changes its sign and its y-coordinate stays the same.

Therefore, by reflection the answer will be (4,-3).

I only see one question here...

If [tex]y=f(x)[/tex] is a one-to-one function, then it has an inverse such that [tex]f^{-1}(y)=x[/tex]. This means that [tex]f^{-1}(f(x))=x[/tex].

According to the table, [tex]f(1)=-2[/tex]. So by definition of the inverse, we have

[tex]f(1)=-2\implies f^{-1}(f(1))=f^{-1}(-2)\implies\boxed{1=f^{-1}(-2)}[/tex]

so the answer is either B or D (they're both the same...)

In an article about disinflation, various investments were examined. The investments included stocks, bonds, and real estate. Suppose that a random sample of 200 rates of return on real estate investments was computed and recorded. Assuming that the standard deviation of all rates of return on real estate investments is 2.25%, estimate an interval for the mean rate of return on all real estate investments with 95% confidence
Interpret the estimate.

Answers

Answer:

Step-by-step explanation:

Using the formula for calculating the confidence interval to estimate an interval for the mean rate of return on all real estate investments with 95% confidence;

Confidence Interval = xbar±(Z*S/√n)

xbar is the mean = 20%(assumed since we are not given)

n is the sample size = 200

S is the standard deviation = 2.25%

Z is the Z score at 95% confidence interval = 1.960

Confidence Interval = 20±(1.96*2.25/√200)

Confidence Interval = 20±(1.96*2.25/14.14)

Confidence Interval = 20±(1.96*0.159)

Confidence Interval = 20±0.312

Confidence Interval = (20-0.312, 20+0.312)

Confidence Interval = (19.688, 20.312)

Hence the interval for the mean rate of return on all real estate investments with 95% confidence is 19.688<x<20.312.

This means that the minimum rate of return on investment is 19.688% and the maximum rate of return on investment is 20.312%.(assuming 20% as the mean)

A survey of 100 people found that 35 people exercise in the morning, 45 people exercise in the afternoon, and 20 people exercise at night. Tara claims that 35:55, 45:80, and 20:65 are possible ratios from this data. Jim claims that 35:100, 45:100, and 20:100 are possible ratios from this data. Who is correct? Explain.

Answers

100 total people ... 35 exercise in the morning ... 45 in the afternoon ... and 20 at night

Jim is correct ...

35/100 is the ratio of people who exercise in the morning to total people.

45/100 is the ratio of afternoon exercisers to total people

20/100 is the ratio of night exercisers to total people

Answer: Jim is correct because 35:100, 45:100, and 20:100 are part-to-whole comparisons. There are other possible part-to-part ratios from the data.

Answers

Split it into two shapes a square and a triangle.

Square = 3 x 3 = 9

Triangle = 1/2 x base x height

The height would be the side of the square = 3

The base would be the length of the top line minus the length of the side of the square = 7-3 = 4

1/2 x 4 x 3 = 6

Total area = 6 + 9 = 15 square units.

Answer:

15 sq. units

Step-by-step explanation:

area of a trapezoid = (a + b) * h/2

where a = 3, b = 7, h = 3
