Answer:

The slope is 3

Step-by-step explanation:

we use the equation : $m=\frac{y2 - y1}{x2 - x1} = \frac{?}{?} =(simplify)\frac{?}{?}$ to find the slope so when we use the equation it should look like this: $m=\frac{8-2}{(-2)-(-4)} =\frac{6}{2} =(simplify) 3$

Match each interval with its corresponding average rate of change for q(x) = (x + 3)2. 1. -6 ≤ x ≤ -4 1 2. -3 ≤ x ≤ 0 -4 3. -6 ≤

MrMuchimi

The average rate of change of a function f(x) in an interval, a < x < b is given by
$\frac{f(b) - f(a)}{b - a}$

Given q(x) = (x + 3)^2

1.) The average rate of change of q(x) in the interval -6 ≤ x ≤ -4 is given by $\frac{q(-4)-q(-6)}{-4-(-6)} = \frac{(-4+3)^2-(-6+3)^2}{-4+6} = \frac{1-9}{2} = \frac{-8}{2} =-4$

2.) The average rate of change of q(x) in the interval -3 ≤ x ≤ 0 is given by $\frac{q(0)-q(-3)}{0-(-3)} = \frac{(0+3)^2-(-3+3)^2}{0+3} = \frac{9-0}{3} = \frac{9}{3} =3$

3.) The average rate of change of q(x) in the interval -6 ≤ x ≤ -3 is given by $\frac{q(-3)-q(-6)}{-3-(-6)} = \frac{(-3+3)^2-(-6+3)^2}{-3+6} = \frac{0-9}{3} = \frac{-9}{3} =-3$

4.) The average rate of change of q(x) in the interval -3 ≤ x ≤ -2 is given by $\frac{q(-2)-q(-3)}{-2-(-3)} = \frac{(-2+3)^2-(-3+3)^2}{-2+3} = \frac{1-0}{1} = \frac{1}{1} =1$

5.) The average rate of change of q(x) in the interval -4 ≤ x ≤ -3 is given by $\frac{q(-3)-q(-4)}{-3-(-4)} = \frac{(-3+3)^2-(-4+3)^2}{-3+4} = \frac{0-1}{1} = \frac{-1}{1} =-1$

6.) The average rate of change of q(x) in the interval -6 ≤ x ≤ 0 is given by $\frac{q(0)-q(-6)}{0-(-6)} = \frac{(0+3)^2-(-6+3)^2}{0+6} = \frac{9-9}{6} = \frac{0}{6} =0$

Help please I don’t understand probability and need the correct answers to these questions.

vampirchik [111]

Answer:

1) = 0.175

2) = 0.244

3) = 0.168

Step-by-step explanation:

Experimental, not theoretical, so we use the results table.

1. P(3 n Tails) = 62/(53 + 65 + 49 + 71 + 54 + 62) = 0.175

2. P(Woman n Up) = 39/(36 + 43 + 39 + 42) = 0.244

3. P(Tuna n Wheat Bread) = 23/(22 + 24 + 21 + 22 + 25 + 23) = 0.168

Helen [10]

Incomplete Question the Complete Question with figure is below.

Answer:

The correct option is C . 48°

Therefore,

measure angle U is 48°.

Step-by-step explanation:

Given:

ΔEFG ~ ΔTUV

∠ F = 48°

To Find:

measure angle U = ?

Solution:

When the two Triangles are Similar then their Vertices are correspondence to each other. the correspondence of vertices are as

For, ΔEFG ~ ΔTUV

E ↔ T

F ↔ U

G ↔ V

Also Corresponding angles of Similar Triangles are Congruent.

Therefore

∠F ≅ ∠U Corresponding angles of Similar Triangles are Congruent.

But ∠ F = 48° ......Given

∴ ∠U = 48° ...........Transitive Property

Therefore,

measure angle U is 48°.
