So,, there are 5 different flavors. A total of 180 people were asked. Hence, the hypothesis that there is no significant difference is that every flavor gets 180/5=36 flavors. x^2=
. In this case, mi is the proportion of the hypothesis, thus 36, n=180 and xi is the number of actual observations. Substituting the known quantities, we get that x^2=9. The degree of association is given by
. This yields around 0.10, much higher than our limit.
Answer: 9
Step-by-step explanation:
To square a number, you multiply it by itself twice.
In this case, your answer would be 3 x 3 = 9.
Hope it helps! :)
Answer:
<h2>15.3 gallons</h2><h2 />
Step-by-step explanation:
ratio and proportion
<u>420 miles </u> = <u> 357 miles</u>
18 gallons x gallons
420 (x) = 357 (18)
x = 6426 / 420
x = 15.3 gallons
total number of student in the data set in the dataset is 90
Answer:
A. 84 pi feet^2
Step-by-step explanation:
So the lateral area is the rectangular piece on the net
In order for it to be an actual cylinder the 2 circles are congruent
Therefore the radi, area, circumference ect.. are the same.
So the only missing measurement we need to find the lateral area is the length of the rectangular piece
If you visualize a cylinder, the rectangular piece goes around the perimeter/circumference of the circle
So that means that the length of the rectangle is the circumference of the circle
Circumference = 2*pi*r
2 * pi * 6
= 12 pi
Then 7*12 pi
=84 pi
So the lateral area is 84 pi
