Answer:

(6, 80)

Step-by-step explanation:

First, should mark your y intercepts, which are +20 and +50 on your y axis.

Next, you must know how to use rise over run.

10 = 10/1 and 5 = 5/1

If you have a graph, you can use it for this step:

Next, you rise up 10 then go right 1 because it is positive, and do the same thing over and over again for your first equation. For your next equation, you go up 5 and right 1 since it is also positive.

The null and alternative hypotheses are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tail

WINSTONCH [101]

Answer: Two-tailed test.

Population mean is the parameter which is tested.

Step-by-step explanation:

Given : $H_0: \mu=105$

$H_1:\mu\neq105$

We know that , the alternative hypothesis ( $H_1$ ) indicates kind of the hypothesis test we need to perform whether left-tailed, right-tailed, or two-tailed.

Here, the alternative hypothesis ( $H_1$ ) is two-tailed, so the hypothesis test is a two-tailed test.

Also, the parameter present in the hypothesis is $\mu$ which is a symbol to represent the population mean.

Thus , Population mean is the parameter which is tested.

Can someone please help me with this (make sure it’s right)

Mekhanik [1.2K]

Step-by-step explanation:

$\tan \angle A = \frac{3}{6} \\ \\ \therefore \: \tan \angle A = 0.5 \\ \\ \therefore \: \angle A = { \tan}^{ - 1} 0.5 \\ \\ \therefore \: \angle A = { \tan}^{ - 1} 0.5 \\ \\ \therefore \: \angle A = { \tan}^{ - 1} tan(26.565051177 \degree) \\ \\ \therefore \: \angle A = 26.57 \degree$

Suppose you know that <T and<S are supplementary, and that m<T=3(m<S). How can you find m<T?

stealth61 [152]

Answer:

∠T = 135°

Step-by-step explanation:

Supplementary angles sum to 180°, thus

∠T + ∠S = 180

However, ∠T = 3∠S, hence

3∠S + ∠S = 180

4∠S = 180 ( divide both sides by 4 )

∠S = 45°, hence

∠T = 180° - 45° = 135°
