Complete the equation of the line through (3,-1) and (4,7)<br> (use exact numbers) <br> Y=

Artemon [7]

The line passing through points $(x_1, y_1)$ and $(x_2, y_2)$ is given by

$\dfrac{x-x_1}{x_2-x_1}=\dfrac{y-y_1}{y_2-y_1}$

Plug your values to get

$\dfrac{x-3}{4-3}=\dfrac{y+1}{7+1} \iff \dfrac{x-3}{1}=\dfrac{y+1}{8}$

Multiply both sides by 8 to get

$8(x-3)=y+1 \iff y=8x-24-1=8x-25$

N =64

faust18 [17]

Answer:

B. 1.70

Step-by-step explanation:

Given:

$n=64$
$\overline{x}=65.1$
$\sigma=24$
$\textsf{h}_0:\mu=60$
$\textsf{h}_1:\mu\neq 60$

$\textsf{If }\: X \sim\textsf{N}(\mu,\sigma^2)\:\textsf{ then }\: \overline{X} \sim \left(\mu,\dfrac{\sigma^2}{n}\right) \implies Z=\dfrac{\overline{X}-\mu}{\sigma / \sqrt{n}} \sim \textsf{N}(0,1)$

$\textsf{then test statistic is}: \quad z=\dfrac{\overline{x}-\mu}{\sigma / \sqrt{n}}$

Substituting the given values into the formula to find the test statistic z:

$\begin{aligned}\implies z &=\dfrac{65.1-60}{24 / \sqrt{64}}\\\\&=\dfrac{5.1}{3}\\\\&=\dfrac{17}{10}\\\\&=1.7\end{aligned}$
