100% + 25% is 120% then 120 as a decimal 1.20 then you do 1.20 x 65 = 78
soo the selling price is $78
The answer is D. It is that because there are a total 24 grammes of fat and a total of 8 servings. To get your answer you have to divide 24 by 8 (24/8)=3
Answer:
The critical value is T = 3.143.
Step-by-step explanation:
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 = 7 - 1 = 6
98% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 6 degrees of freedom(y-axis) and a confidence level of 
. So we have T = 3.143.
The critical value is T = 3.143.
Answer: a. 5/12 b. 10 hours
Step-by-step explanation:
5/8 x 2/3 = 10/24 = 5/12
she spends 5/12 of the day awake at home
