Solve for n.<br><br> n + 1 = 4(n – 8)

kolezko [41]

N + 1 = 4(n – 8)
Use distributive property for this part: 4(n – 8) ----> 4n - 32

n + 1 = 4n - 32

Get the variable on one side:

n + 1 = 4n - 32
-n -n

1= 3n - 32

Get the variable on its own:

1= 3n - 32
+32 +32

33 = 3n

Divide by 3 on both sides:

33/3 = 3n/3

n = 11

We have a null hypothesis that u=3.75, but we are reluctant to accept this as the population value in case the true value is dif

Gala2k [10]

Answer:

option A

Step-by-step explanation:

To Test

H₀ : μ = 3.75

H₁ : μ ≠ 3.75

now,

If μ = 3.95 then it means H₀ is not true.

then the probability is rejecting the null hypothesis.

Hence, the probability is the power of the test against the alternative μ=3.95

The correct answer is option A

What is the description of angle 4 as it relates to the situation below?

Murljashka [212]

Answer:

The correct option is 1.

Step-by-step explanation:

The angle of elevation is the angle formed by the line of sight and the horizontal plane for an object above the horizontal.

The angle of depression is the angle formed by the line of sight and the horizontal plane for an object below the horizontal.

Since the angle 4 is the angle between the line of sight and the ground for an object above the horizontal, therefore angle 4 is the angle of elevation from the person to the radar tower.

1. "Angle 4 is the angle of elevation from the person to the radar tower."

This statement is true.

2. "Angle 4 is the angle of depression from the radar tower to the person".

This statement is is false.

3. "Angle 4 is the angle of depression from the person to the radar tower".

This statement is false.

4. "Angle 4 is the angle of elevation from the radar tower to the person".

This statement is false.
