Answer:
12 and 48
Step-by-step explanation:
let n be the larger number , then n is the smaller number and their sum is
x + x = 60 ( multiply through by 4 to clear the fraction )
4x + x = 240 , that is
5x = 240 ( divide both sides by 5 )
x = 48
smaller number = × 48 = 12
The 2 numbers are 12 and 48
Answer:
t Subscript alpha divided by 2 = 2.921
Step-by-step explanation:
With sample sizes lower than 30, we use the t-test.
Otherwise, we use the z-test.
Here, n = 17
So we use the t-test.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 17 - 1 = 16
Now, we have to find a value of T, which is found looking at the t table, with 16 degrees of freedom(y-axis) and a confidence level of 0.99(). So we have T = 2.921
So the correct answer is:
t Subscript alpha divided by 2 = 2.921
