A circle is made up of 360 degrees. Lets find the decimal form of each part of the circle.

White: 122.4/360 = 0.34

Red: 115.2/360 = 0.32

Silver: 68.4/360 = 0.19

Blue: 54/360 = 0.15

Now, solve for the car color that is not red or blue.

1 - (0.15 + 0.32)

1 - (0.47)

0.53

Therefore, the answer is C.

Best of Luck!

Answer:

Step-by-step explanation:

First, multiple 3 by 44 to find the number of pencils total. 3x44=132.

Then, divide 22 into 132. 132/22=6.

Therefore, each student received 6 pencils.

What’s the answer to 14?

vfiekz [6]

Answer:

|t -(-5)| = 1.5
[-6.5, -3.5] = [minimum, maximum]

Step-by-step explanation:

The magnitude of the difference between the temperature (t) and -5 will be 1.5 at the limits:

|t -(-5)| = 1.5

This is equivalent to two equations:

t +5 = -1.5
t +5 = 1.5

In each case, the equation is solved by subtracting 5 from both sides:

t = -6.5 . . . . minimum allowed temperature
t = -3.5 . . . . maximum allowed temperature

Circumference + perimeter =38
x = circumference of circle
find r in terms of x
2 $\pi$ r=x
r= $\frac{x}{2 \pi }$
Area= $\pi$ r^2
so..
A= $\pi$ ( $\frac{x}{2 \pi }$ )^2
= $\pi$ ( $\frac{x^{2} }{4 \pi ^{2} }$ )
= $\frac{x^{2} }{4 \pi }$

(38-x) is perimeter
then
$\frac{38-x}{4}$
( $\frac{38-x}{4}$ )^2
$\frac{x^{2} }{4 \pi }$ + ( $\frac{38-x}{4}$ )^2
then you graph it and it equals
16.716 cm the circumference of the circle

An administrator at a local high school wants to investigate whether there is an association between the grade level of a studen

Nataliya [291]

Answer:

Step-by-step explanation:

The following is how the p-value should be interpreted:

The probability of getting the test statistics value at least as intense as it might have been acquired during the test, assuming the null hypothesis is true, is considered as the p-value.

Null hypothesis

$\mathbf{H_o :}$ A student's grade level has no bearing or association on how they commute to school.

Alternative hypothesis;

$\mathbf{H_1: }$ There is a link between a student's grade level and the way they get to school.

The test statistic's value is 14.63, and the p-value is 0.2636.

As a result, the p-value is interpreted as that of option c in the question.

Tell whether the angles are complementary or supplementary.

igomit [66]

Answer:

complementary

Step-by-step explanation:

The total angle is a right angle. Complementary angles are angles that add up to 90 degrees. Right angles are 90 degrees so the answer is complementary.
