If p varies directly with q, and p = 10 when q = 5, what is the value of p when q = 20

The value of p would be 40. This is because the ratio of p:q = 10:5. this could be simplify into p:q = 2:1. Applying the ratio p:20 = 2:1, P=40.

Find the value of p for which 81p ÷ 9p = 94 ? ​
Radda [10]

Answer:

p = 10.44

Step-by-step explanation:

There is no solution. If the question was 81p / 9 = 94, it could be done.

The way it is written the ps cancel out and you get 9 = 94 which is impossible.

But let's assume you meant

81p / 9 = 94

Then you get 9p = 94      Divide both sides by 9

81p/9 = 94              

9p = 94                              Divide both sides by 9

9p/9 = 94/9

p = 10.44

Suppose a random sample of size is selected from a population with . Find the value of the standard error of the mean in each of
77julia77 [94]

Answer:

A) σ_x' = 1.4142

B) σ_x' = 1.4135

C) σ_x' = 1.4073

D) σ_x' = 1.343

Step-by-step explanation:

We are given;

σ = 10

n = 50

A) when size is infinite, the standard deviation of the sample mean is given by the formula;

σ_x' = σ/√n

Thus,

σ_x' = 10/√50

σ_x' = 1.4142

B) size is given, thus, the standard deviation of the sample mean is given by the formula;

σ_x' = (σ/√n)√((N - n)/(N - 1))

Thus, with size of N = 50,000, we have;

σ_x' = 1.4142 x √((50000 - 50)/(50000 - 1))

σ_x' = 1.4142 x 0.9995

σ_x' = 1.4135

C) at N = 5000;

σ_x' = 1.4142 x √((5000 - 50)/(5000 - 1))

σ_x' = 1.4073

D) at N = 500;

σ_x' = 1.4142 x √((500 - 50)/(500 - 1))

σ_x' = 1.343
