The area under the curve between the two values is (d) 0.0750

<h3>How to determine the area?</h3>

From the table, we have:

P(z = -0.45) = 0.3264

P(z = -0.67) = 0.2514

The area under the curve is calculated as:

Area = P(z = -0.45) - P(z = -0.67)

So, we have:

Area = 0.3264 - 0.2514

Evaluate the difference

Area = 0.0750

Hence, the area under the curve between the two values is (d) 0.0750

Answer two questions about Equations AAA and BBB: \begin{aligned} A.&&\dfrac x4+1&=-3 \\\\ B.&&x+4&=-12

luda_lava [24]

The given equations are as follows

$\begin{aligned} A.&&\dfrac x4+1&=-3 \\\\ B.&&x+4&=-12 \end{aligned}$

(1) First, multiply both sides of equation A by 4, we have

$4\times\left(\frac{x}{4} +1\right)=4\times(-3)$

Then, rewrite the left-hand side of the above equation by using the distributive property, we have

$4\times\frac{x}{4}+4\times1=4(-3)$

$\Rightarrow x+4=-12$

This is the required equation B.

In this way, first use choice D: Multiply both sides by the same non-zero constant, i.e 4.

Then, apply choice A to solve the equation, i.e using the distributive property to solve the left-hand side of the equation.

(2) In the previous answer, equation B has been derived from equation A, hence, both the equations are equivalent.

As both the equations are the same, so both will have the same solution.

Yes, they have the same solution.

Answer:

8 dolls

Step-by-step explanation:

METHOD 1:

Step 1: Convert 25% into decimal (0.25)

Step 2: Multiply by 32 (32 × 0.25 = 8)

METHOD 2:

25% of a number will be one-fourth of that number. Divide 32 by 4 to get 8 (or multiply 32 by 1/4).
