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

Dahasolnce [82]

Answer: The parametric is being tested here is "p" (population proportion).

The hypothesis test is left-tailed.

Step-by-step explanation:

Given : The null and alternative hypotheses are

$H_0:\ p=0.2\\\\H_1:\ p$

The parametric is being tested here is "p", where p stands for population proportion.

Also, the type of test depends on the alternative hypotheses.

Since the alternative hypotheses is left-tailed, so the hypothesis test is left-tailed.

I need help.<br> Math is really hard

alekssr [168]

Answer:

The value of x in terms of b is: $\mathbf{x=-\frac{6}{2b}}$

The value of x when b is 3 is: x = -1

Step-by-step explanation:

We are given the function: $-2(bx-5)=16$

First we need to find

The value of x in terms of b

We need to find value of x

$-2(bx-5)=16$

Multiply -2 with terms inside the bracket

$-2bx+10=16$

Subtract 10 from both sides

$-2bx+10-10=16-10\\-2bx=6$

Divide both sides by -2b

$\frac{-2bx}{-2b}=\frac{6}{-2b}\\x=-\frac{6}{2b}$

So, The value of x in terms of b is: $\mathbf{x=-\frac{6}{2b}}$

The value of x when b is 3

We have the equation for the value of x in terms of b:

$\mathbf{x=-\frac{6}{2b}}$

Put b = 3

$x=-\frac{6}{2(3)}\\x=-\frac{6}{6}\\x=-1$

So, The value of x when b is 3 is: x = -1

Find the difference.<br><br> 6rs – (-2rs)

lilavasa [31]

There is no difference, 6rs-(-2rs) if you get rid of the parenthesis you are left with 6rs- -2rs and two negatives make a positive therefore the answer will become 8rs... I hope this helps :)
