A manufacturer of cell phone screens is concerned because 12 percent of the screens manufactured using a previous process were r
fomenos

Answer: A.

H_0:p=0.12\\\\H_a:p

Step-by-step explanation:

Null hypothesis(H_0) : A statement describing population parameters as per the objective of the study. It usually takes "≤,≥,=" signs.  

Alternative hypothesis (H_a): A statement describing population parameters as per the objective of the study. It usually takes ">, <, ≠" signs.

Let p be the proportion of screens that will be rejected.

12 percent of the screens manufactured using a previous process were rejected at the final inspection.

(i.e. p= 0.12)

Objective of the study = whether the new process<em> reduces </em>the population proportion of screens that will be rejected

i.e. p< 0.12

So, the appropriate hypotheses to investigate whether the new process reduces the population proportion of screens that will be rejected:

H_0:p=0.12\\\\H_a:p

Helppppppppppppppp pleaseeeeee!
stepan [7]

Answer and Explanation:

You got the first one right!

2. You do the same as you did for the first one: to combine the exponents, you multiple 2 by 9 = 18, and now 18 is your new exponent.

3^{2*9} = 3^{18} , which is the answer

3. Here, you can split up the inside so that you have:

2^5*(y^2)^5= 32*y^{2*5}=32y^{10} , which is the answer

Hope this helps! Please give me brainliest if possible.

What is -8-2r=-7v-7v+16
Mariulka [41]

Answer:

r=7v−12

Step-by-step explanation:

Let's solve for r.

−8−2r=−7v−7v+16

Step 1: Add 8 to both sides.

−2r−8+8=−14v+16+8

−2r=−14v+24

Step 2: Divide both sides by -2.

−2r

−2

=

−14v+24

−2

r=7v−12
