Answer:
9.4 cm^3
Step-by-step explanation:
This figure is a cylinder so the formula is V=πr^2h
r is the radius and h is the height
Here we can see the height is 3 and the radius is 1
V=π(1)^2(3)
V=π3
V=9.42 (assuming π is 3.14)
Rounded to the nearest tenth is 9.4
Answer:
11.04
Step-by-step explanation:
Given the data:
29, 15, 22, 52, 38
The mean absolute deviation :
Mean, m = Σx / n
n = sample size = 5
29 + 15 + 22 + 52 + 38 = 156
Mean = 156 / 5 = 31.2
Mean absolute deviation (MAD):
Σ|x - m| / n
(|29 - 31.2| + |15 - 31.2| + |22 - 31.2| + |52 - 31.2| + |38 - 31.2|) / 5
(2.2 + 16.2 + 9.2 + 20.8 + 6.8) / 5
55.2 / 5
= 11.04
In school 1, 50% of the students scored above 83 and in school 2, 50% of the class scored above 81.
In school 1, 25% of the students scored above 86 and in school 2, 25% of the class scored above 85.
In school 1, 25% of the students scored below 77 and in school 2, 25% of the class scored below 73.
The minimum score for school 1 is 68 while that of school 2 is 65.
The maximum score for school 1 is 95 while that of school 2 is 98.
In all this measures of center, the data from both schools are close together, so we can conclude that both schools did abut the same on the test.
Answer:
the awnser is -0.9 ......
97, 19+(11+37)=19+(48)=67 and then add 30 because of 19 and 11 and you get 97
