You just have to do the opposite of what Corey did.
So (18 ÷3 +17) ×2 -25
The answer is 21
Hope I can help you, brainliest answer? :)
Each pound of potato salad serves 6 people and the average number of pounds of potato salad that each person is served will be pound.
<u><em>Explanation</em></u>
At a party of 102 people, 17 pounds of potato salad is served.
<u>a.</u> Suppose, each pound of potato salad is served to number of people.
So, 17 pounds of salad is served to or number of people. That means......
So, each pound of potato salad is served to 6 people.
<u>b.</u> Suppose, the average number of pounds of potato salad that each person is served is
So, the total number of pounds of salad, served to 102 people pounds pounds. That means .....
So, the average number of pounds of potato salad that each person is served will be pound.
Answer:
A = 72, P = 38
Step-by-step explanation:
Area can be found by getting the area of the overall figure, and then subtracting the blank space in the corner
12 * 7 = 84
3 * 4 = 12(invisible rectangle in top right)
84 - 12 = 72
Perimeter can be found by adding all of the sides
12 + 7 + (12-4) + 3 + 4 + (7-4)
The numbers in brackets are the unlabeled sides on the top and left.
Answer:
The 90 % confidence interval for the mean population is (11.176 ; 20.824 )
Rounding to at least two decimal places would give 11.18 , 20.83
Step-by-step explanation:
Mean = x`= 16 miles per hour
standard deviation =s= 4.1 miles per hour
n= 4
= 4.1/√4= 4.1/2= 2.05
1-α= 0.9
degrees of freedom =n-1= df= 3
∈ ( estimator t with 90 % and df= 3 from t - table ) 2.353
Using Students' t - test
x`±∈ *
Putting values
16 ± 2.353 * 2.05
= 16 + 4.82365
20.824 ; 11.176
The 90 % confidence interval for the mean population is (11.176 ; 20.824 )
Rounding to at least two decimal places would give 11.18 , 20.83
If
is left, that means
was spent. So
of the total amount is equal to 39.. Let's say x to the total amount.
