Answer:

m∠z = 135°

Step-by-step explanation:

The given figure is a regular octagon. It has 8 sides which are equal in measure. Since it is a regular octagon each interior angle is also in the same measure.

We have formula to find the sum of the interior angles of a polygon.

The sum of the interior angles of a polygon = (n -2)180°, where "n" is the number of sides.

Here n = 8

Now plug in n = 8 and find the sum of the interior angles.

= (8 -2)180

= 6*180

The sum of the interior angles of the regular Octagon = 1080°

Therefore, m∠z = $\frac{1080}{8}$ = 135°

The sum of interior angles in a regular octagon equals 1080 degrees.

So 1080 / 8 = 135

z = 135

Let f(x)=2x-1 and g(x)=x^2 -3. Find (f o g)(-3)

anzhelika [568]

(f o g)(-3) = (f(g(-3))
Because g is on the inside, we carry out g first.

g(x) = x^2 - 3
Substitute -3 in for x.
g(-3) = (-3)^2 - 3 = 9 - 3 = 6
g(-3) = 6

Next, carry out f on the result of g(-3)
f(6) = 2(6) - 1
= 12 - 1
= 11
So the answer is 11.

Ad libitum [116K]

16 red cars and 12 black cars. He put half of each colour in each box. Therefore he would put 8 red and 6 black in each box. 8 red + 6 black is 14. Therefore he would have 14 cars in each box.

daser333 [38]

Answer:

The point estimate for the proportion of 18-year-olds who have not graduated from high school in this city is 0.25.

Step-by-step explanation:

The point estimate is the sample proportion.

She draws a random sample of 80 18-year-olds in the city and finds that 20 of them have not graduated from high school.

This means that:

$p = \frac{20}{80} = 0.25$

The point estimate for the proportion of 18-year-olds who have not graduated from high school in this city is 0.25.
