What is the value of p(24)?

Savatey [412]

Answer:

24p

Step-by-step explanation:

I'm pretty sure that this is the answer because the question was "What is the value P(24)?" which means you have to use the commutative property to reorder the terms.

Hope this helped!

A supervisor records the repair cost for 22 randomly selected VCRs. A sample mean of $75.50 and standard deviation of $18.07 are

Virty [35]

Answer:

The 99% confidence interval for the mean repair cost for the VCRs

(65.801, 85.199)

Step-by-step explanation:

Explanation:-

Mean of the sample(x⁻) = $75.50

Given the standard deviation of the sample (S) = $18.07

Given the size of the sample 'n' = 22

Degrees of freedom = n-1 =22-1 =21

critical value t₍₀.₀₁, ₂₁₎ = 2.5176

The 99% confidence interval for the mean repair cost for the VCRs

$(x^{-} - t_{0.01} \frac{S.D}{\sqrt{n} } , x^{-} +t_{0.01} \frac{S.D}{\sqrt{n} })$

$(75.50 - 2.5176 \frac{18.07}{\sqrt{22} } , 75.50 +2.5176 \frac{18.07}{\sqrt{22} })$

( 75.50 - 9.699 , 75.50 + 9.699 )

(65.801, 85.199)

Final answer:-

The 99% confidence interval for the mean repair cost for the VCRs

(65.801, 85.199)

Well if the fish is directly below the bird then there distance forms a straight vertical line. so to find the vertical distance you can add the 75 meters below sea level and the 887 meters above and get 962
