What is 12 1/3-10 11/12

Brut [27]

Answer:

1 5/12

Step-by-step explanation:

12 1/3 - 10 11/12

We need to get a common denominator of 12

12 1/3 * 4/4 - 10 11/12

12 4/12 - 10 11/12

We need to borrow from the 12 (the whole number) because the 2nd fraction is bigger than the first

12 becomes 11 and the 1 becomes 12/12

11+ (12/12 + 4/12) - 10 11/12

11 16/12 - 10 11/12

Subtract the whole numbers

11-10 =1

Subtract the fractions

16/12 - 11 /12 = 5 /12

We are left with 1 5/12

A local charity believes they receive more money from people in the Chevy Chase area than from people in the Alexandria area of

kaheart [24]

Answer: The critical value of the test is 2.807.

Step-by-step explanation:

Since we have given that

n = 24

So, the degree of freedom v = n-1 = 24 - 1=23

Since, n>30, so we will use 't-test'.

Here, α = 0.01

so, According to t-table, we get that

$t_{\alpha ,v}=t_{0.01,23}=2.807$

If we take α, then we are taking about two tail test.

If we take $\dfrac{\alpha }{2}$ then we are talking about one tail test.

But in both the cases, the result will be same.

Hence, the critical value of the test is 2.807.
