Answer:

1) A and D

The radius is the distance from the center of a circle to any part of the edge. Both A and D have a radius of three, regardless of what direction they go.

2) 5"

In circle C we see that there is a line segment that is 5" that goes from the center to the edge, or the radius.

3) C

The different variables are representing different points on the circles. The circle that contains a line connecting C and L is circle C.

4) BN

Circle B contains a radius that is the distance from B to N, or BN.

5) EF

The diameter is the distance of a straight line that was pass through the middle of a circle, or its width. The diameter is double the radius. In circle A we see that line EF passes through the center put goes all the way across the circle.

6)IJ

Line IJ isn't even linear, so it could not be the radius. Both AG and BH are straight lines that represent the radius.

7) 6"

The diameter is always twice the radius. In circle A the radius is 3, so the diameter is 6.

8) A and D

Just as we said in the first answer, A and D both have a radius that measures 3 inches.

I hope this helps!

goldfiish [28.3K]

Answer:

Notice that the distance is in the y-axis, and the time in the x-axis.

First, let's see what happens in the four points:

A) You can see that in point A, the steepness of the line increases, this means that the speed of the runner increases in that point.

B) In this point, the runner that increased his/her speed in point A crosses the graph of another runner, this means that they are at the same distance to the end and at the same time.

C) In this point again two runners are at the same distance and the same time, and we also can see that the runer that increased his/her speed at point A, now has reached the end of the race (because his line stops increasing, wich means that he/she already finished the race)

D) The las runner finishes the race at point D.

Then the first runner that finishes the race is the one with the shorter graph (shorter graph means that he ran for less time than the others, wich means that he/she finished first)

The last runner is the one that finished at point D,

The middle one finishes right after the point C.

Plug in x = 5
f(5) = 2(5) - 4
f(5) = 10 - 4

At a particular academically challenging high school, the average gpa of a high school senior is known to be normally distribute

brilliants [131]

Solution: The 90% confidence interval for the population mean is:

$\bar{x} \pm t_{\frac{0.1}{2}} \frac{s}{\sqrt{n}}$

Where:

$\bar{x}=2.71$

$s=\sqrt{0.25} =0.5$

$t_{\frac{0.1}{2}}=1.729$ is the critical value at 0.1 significance level for df = n-1 =20-1=19

$2.71 \pm 1.729 \frac{0.5}{\sqrt{20}}$

$2.71 \pm0.19$

$\left( 2.71-0.19,2.71+0.19\right)$

$\left(2.52,2.90 \right)$

Therefore, the 90% confidence interval for the population mean is $\left(2.52,2.90 \right)$

When Ryan walks into the auditorium, there are 5 available seats in the first row, 10 in the second row, and 2 in the third row.

29%!!!!!!! There are a total of 17 seats, and since there are 5 seats in the first row, you are going to divide 5 by 17 and that gives you 0.2<span>94117647 which you will round to .29 and you have your answer. The probability that Ryan's seat will be in the first row is 29%!</span>
