The circles are similar.
Step-by-step explanation:
You can move the small circle 3 units to the right and then 5 units up. The center of the small circle will also be the center of the larger circle. Then you dilate the small circle by a scale factor of 5 to get the larger circle.
There are four mutually exclusive groups, therefore, the probability of one item being classified into any of the four groups is 1/4 or 0.25.
The expected number of items is calculated as the product of the probability and the total number of observations. For this problem, the probability of an item being classified to group 1 is 0.25 and the total number of observations is 400. Therefore, the expected number of items is

The expected number is
100.
The 20 N force is makes an angle of 20° relative to the incline. Then the work performed by this force is
(20 N) (3 m) cos(20°) ≈ 56.4 J
Answer:
c
Step-by-step explanation:
The formula for the volume of a square pyramid is
. a is your base edge and the h is your height. In this case it would be
. when you wokr it out it would be 58.333, or 58 which is c.
also you would do 5 x 5 then you would multiply it by 7/3.
