Find the midpoint of the line segment
strojnjashka [21]

Answer:

midpoint (5,4)

Step-by-step explanation:

The midpoint(M) of a segment with endpoints (x₁ , y₁) and ( x₂,  y₂) is

where x₁ = 2 and x₂ = 8

y₁ = 0 and y₂ = 8

M = \frac{x_1 + x_2}{2} ,\frac{y_1 + y_2}{2}

M = \frac{2 + 8}{2} ,\frac{0 + 8}{2}

M = 5 , 4

Tim scored 35, 38, and 36 points on three tests. How many points should he get on the fourth test to get an average score of 40?
My name is Ann [436]
I think 51 because if you were to do it reverse then it would be 40x4=160 then -35-36-38 it would be 51.

10# A consumer advocacy group is doing a large study on car rental practices. Among other things, the consumer group would like
ella [17]

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

y = -x + 5

Step-by-step explanation:

X, Y, and B is given using fomula y = m(x) + b

Subsitute those variables.

0 = -(5) + b

Solve for m.

0 = -5 + b

+5  +5

b = 5.
