ANSWER:

104

STEP-BY-STEP EXPLANATION:

Given:

Standard deviation (σ) = 700

Confidence level = 95%

Mean error (Eμ) = 135

We have for a confidence level of 95%:

$\begin{gathered} \alpha=100\%-95\%=5\%=0.05 \\ \\ \alpha\text{/2}=\frac{0.05}{2}=0.025 \\ \\ \text{ The corresponding Z value for \alpha/2 = 0.025 is as follows:} \\ \\ Z_{\alpha\text{/2}}=1.96 \end{gathered}$

Now, we calculate the minimum value of the sample size as follows:

$\begin{gathered} n=\left(\frac{Z_{\alpha\text{/2}}\cdot\sigma}{E}\right)^2 \\ \\ \text{ We replacing:} \\ \\ \:n=\left(\frac{1.96\cdot 700}{135}\right)^2 \\ \\ \:n=103.2858\cong104 \end{gathered}$

The minimum sample size needed is 104

40 is 1/10 of 400 yes of no

kumpel [21]

YES!

You know it like this:

if something (x)is 1/10 of a whole(y), then you need 10 of this for the whole (y).

So the whole is then:

y=x*10

if x=40:

y=40*10=400,,

so yes, 40 is 1/10 of 400.

Question 1 (Essay Worth 10 points)

FromTheMoon [43]

The equation 7x + 3x - 18 = 6(x+3) is 9

<h3>What is equation?</h3>

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

given:

7x + 3x - 18 = 6(x+3)

7x + 3x - 18 = 6x+18 [Distributive Property]

10x-18= 6x+18 [Addition Property of Equality]

10x-6x= 18+18 [Combine Like Terms ]

4x=36 [Subtraction Property of Equality]

4*x=36 [Multiplication Property of Equality]

x=36/4 [Division Property of Equality]

x=9
