Mathematics

3(y + 4) - (x - 1)

x = 3

y = 2


First plug in the numbers into the variables. Or plug in 3 for "x" and 2 for "y" in the equation.

3(y + 4) - (x - 1)

3(2 + 4) - (3 - 1)    Simplify the numbers in the parentheses

3(6) - (2)

18 - 2 = 16

Put the values of x = 3 and y = 2 to the expression 3(y + 4) - (x - 1):

3(2 + 4) - (3 - 1) = 3(6) - (2) = 18 - 2 = 16

What sample size should be used if we would like to estimate the mean age of the college students at a particular campus with 95
nevsk [136]

Answer: 12

Step-by-step explanation:

The formula to find the sample size is given by:-

n=(\dfrac{z_c\cdot \sigma}{E})^2 , where \sigma is the population standard deviation, z_c is the z-value for the (1-\alpha) confidence interval and E is the margin of error .

As per given , we have

Population standard deviation : \sigma=5.1

z-value for 95% confidence interval : z_c=1.960

Margin of error : E= 3

Then, the required minimum sample :-

n=(\dfrac{(1.96)\cdot (5.1)}{3})^2\\\\\Rightarrow\ n=(3.332)^2=11.102224\approx12

Hence, the required minimum sample size = 12
