Step-by-step explanation:

(x₁, y₁) = (-3, -4) and (x₂, y₂) = (0, 4)

$m = \frac{y2 - y1}{x2 - x1} \\ m = \frac{ 4 - ( - 4)}{0 - ( - 3)} \\ m = \frac{4 + 4}{3} \\ m = \frac{8}{3}$

MA_775_DIABLO [31]

Answer:

$t=\frac{11.7-12}{\frac{0.2}{\sqrt{25}}}=-7.5$

Step-by-step explanation:

Information given

$\bar X=11.7$ represent the sample mean of amount of liquid

$s=0.2$ represent the standard deviation

$n=25$ sample size

$\mu_o =12$ represent the value that we want to check

t would represent the statistic (variable of interest)

$p_v$ represent the p value for the test (variable of interest)

System of hypothesis

We want to verify if the true mean for the amount of liquid is lower than 12 ounces, and the hypothesis are given by:

Null hypothesis: $\mu \geq 12$

Alternative hypothesis: $\mu < 12$

The statistic is given by:

$t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}$ (1)

Replacing we got:

$t=\frac{11.7-12}{\frac{0.2}{\sqrt{25}}}=-7.5$

What is the equation for the line of reflection? On a coordinate plane, triangle A B C has points (6, 3.7), (5.4, 2), (1, 3). Tr

Klio2033 [76]

Answer:

The equation of the line of reflection will be x = y.

Step-by-step explanation:

On a coordinate plane, triangle Δ ABC has points (6, 3.7), (5.4, 2), (1, 3). And triangle Δ A'B'C' has points (3.7, 6), (2, 5.4), (3, 1).

Now, Δ A'B'C' is the image triangle of Δ ABC and we have to find the equation of the line of reflection.

We know that after reflection of a point P(h,k) over the line x = y the image will be P'(k,h).

Same is happened in case of Δ ABC and Δ A'B'C'.

Therefore, the equation of the line of reflection will be x = y. (Answer)
