Vis inversely proportional to r, when r = 3, V= 10.
guapka [62]

Answer:

Constant of proportionality = 30

Example: r = 6, V = 5

Step-by-step explanation:

Inverse proportion: V*r = constant

Given r=3, V=10, constant = V*r = 30

Example:

r = 6, V = 30/6 = 5

Degrees Celsius and degrees Fahrenheit are related by C=5/9(F-32).What is F in terms of C?
valina [46]

We are given: Degrees Celsius and degrees Fahrenheit are related by formula

C=\frac{5}{9} (F-32)

To find : Solve formula for F in terms of C.

Solution: We have , C=\frac{5}{9} (F-32)

First we need to get rid 9 from right denominator.

In order to get rid 9 from right denominator, we need to multiply equation both sides by 9.

9*C=9*\frac{5}{9} (F-32)

9C = 5 (F-32).

Distributing 5 on right side over (F-32), we get 5*F - 5*32 = 5F - 160.

9C = 5F - 160.

Adding 160 on both sides,

9C+160 = 5F - 160+160.

9C+160 =5F

Dividing both sides by 5, we get

(9C+160)/5 =5F/5.

\frac{9C+160}{5}=F

Splitting fraction 1/5, we get

F= \frac{1}{5} (9C+160).

The head of a computer science department is interested in estimating the proportion of students entering the department who wil
olya-2409 [2.1K]

Answer:

96

Step-by-step explanation:

From the given information:

At 95% Confidence interval level,Level of significance \alpha 0.05, the value of Z from the standard normal tables = 1.96

Margin of Error = 0.10

Let assume that the estimated proportion = 0.5

therefore; the sample size n can be determined by using the formula: n =(\dfrac{Z}{E})^2 \times p\times (1-p)

n =(\dfrac{1.96}{0.1})^2 \times 0.5\times (1-0.5)

n =(19.6)^2 \times 0.5\times (0.5)

n = 96.04

n \approx 96
