What is the following product?

X+4 if x <5<br> f(x)= 8<br> if 5 2x-1 if 7 For Ax), evaluate the following:<br> a. 10)<br> b. 46)

Dmitry_Shevchenko [17]

Answer:

f(0) = 4 , f(6) = 8

Step-by-step explanation:

Since

$0 < 5$ then f(0) = 0+4 = 4

5 < 6 < 7 therefore f(6) = 8

Select the correct answer from each drop-down menu. Graph shows a four-sided polygon is plotted on a coordinate plane at A (3, 4

zzz [600]

The polygon can be made as shown below. The length of the diagonal of the polygon is 4 units on the x-axis (Horizontally) and 2 units on the y-axis(vertically).

<h3>What is a polygon?</h3>

A polygon is a planar figure characterised by a limited number of straight-line segments joined to create a closed polygonal chain in geometry. A polygon is defined as a bounded planar region, a bounding circuit, or both.

The polygon can be made as shown below. The length of the diagonal of the polygon is 4 units on the x-axis (Horizontally) and 2 units on the y-axis(vertically).

Since translation does not cause a change in the dimensions, therefore, If the polygon translates 3 units to the left and 1 unit down, the length of the diagonal will remain the same, which is If the polygon translates 3 units further to the left and four units down, the length of diagonal will remain the same.

TV advertising agencies face increasing challenges in reaching audience members because viewing TV programs via digital streamin

oksian1 [2.3K]

Answer:

The 99% confidence level for the proportion of all adult Americans who watched streamed programming up to that point in time is (0.514, 0.566). This means that we are 99% sure that the true proportion of all American adults surveyed said they have watched digitally streamed TV programming on some type of device is between 0.514 and 0.566.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the z-score that has a p-value of $1 - \frac{\alpha}{2}$ .

A poll reported that 54% of 2342 American adults surveyed said they have watched digitally streamed TV programming on some type of device.

This means that $\pi = 0.54, n = 2342$

99% confidence level

So $\alpha = 0.01$ , z is the value of Z that has a p-value of $1 - \frac{0.01}{2} = 0.995$ , so $Z = 2.575$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.54 - 2.575\sqrt{\frac{0.54*0.46}{2342}} = 0.514$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.54 + 2.575\sqrt{\frac{0.54*0.46}{2342}} = 0.566$

The 99% confidence level for the proportion of all adult Americans who watched streamed programming up to that point in time is (0.514, 0.566). This means that we are 99% sure that the true proportion of all American adults surveyed said they have watched digitally streamed TV programming on some type of device is between 0.514 and 0.566.

Use the diagram to answer the following questions

n200080 [17]

Answer:

a. line AR, line AV

b. plane TSR, plane QTZ, plane RSZ

c. A, R, V

d. Q, R, S, T

e. QR

f. RQ, RS

Step-by-step explanation:

a. In addition to a name given to a line ("line p"), a line can be named by any two points on that line. Here, possible names are ...

line AR, line RA, line AV, line VA, line RV, line VR

any two of these names will appropriately answer this part of the question.

__

b. In addition to a name given to a plane ("plane W"), a plane can be named by any three points in that plane. Here, there are 5 named points in the plane (3 of which are collinear), so there are 54 possible different names for the plane. Some of them are ...

plane RST, plane TSR, plane QTZ, plane RSZ

__

c. In this diagram, each of the lines shown has three named points on it. Possible answers to this part of the question are ...

{Q, R, S} or {A, R, V}

__

d. Any four of the 5 named points shown in plane W will serve to answer this question. Possible answers are ...

{R, S, T, Z} or {Q, S, T, Z} or {Q, R, T, Z} or {Q, R, S, Z} or {Q, R, S, T}

__

e. Any pair of collinear points will name a line segment. Here, there are 12 possible names for line segments, including ...

QR, RQ, QS, SQ, RS, SR, AR, RA, ...

__

f. Opposite rays can be named by choosing the end point as the middle of three collinear points. Here, the only such middle point is R. We can name pairs of opposite rays on either line. The endpoint of the ray is named first.

{RA, RV} or {RQ, RS}
