Answer:

x = 10

Step-by-step explanation:

Given

AB = 8

AC = x

QR = 12

QS = 15

Required

Find x

Because both triangles are similar, we have:

AB : AC = QR : QS --- Equivalent ratios

This gives:

8 : x = 12 : 15

Convert to fraction

\frac{8}{x} = \frac{12}{15}

Cross Multiply:

12 * x = 8* 15

12x = 120

Divide both sides by 12

x = \frac{120}{12}

x = 10

Help with my homework pls<br> Solve the compound inequality y + 7 ≥ –1 and y∕4 + 3 ≤ 5.
Marianna [84]

Answer:

  -8 ≤ y ≤ 8

Step-by-step explanation:

Subtract 7 from the first one:

  y ≥ -8

Subtract 3 from the second one, then multiply by 4.

  y/4 ≤ 2

  y ≤ 8

Now, you can write these as a compound inequality:

  -8 ≤ y ≤ 8

_____

<em>Additional comment</em>

You basically solve these the same way you would an equation. The only difference is that multiplying or dividing by a negative number will reverse the inequality symbol:

  2 > 1

  -2 < -1 . . . . . multiplied above by -1.

If the p-value = 0.008, what conclusion can be drawn?
Paladinen [302]

Answer: option A is correct, we accept the null hypothesis.

Step-by-step explanation:

At a 5% level of significance, p = 0.05, therefore when p < 0.05, accept the null hypothesis (H°) and reject the alternative hypothesis (H¡). When p > 0.05, we reject the null hypothesis (H°) and accept the alternative hypothesis (H¡)

Given the p-value to be 0.008, this is less than the 5% threshold, that is, 0.05, hence we accept the null hypothesis.
