Answer: b and d
- the average of the difference of scores would be about 19 points if you were to take many many samples of first year and senior pairs.
- for a pair of randomly selected first year and senior students the difference of their scores typically varies from the mean of 19 points by about 45 points.
Step-by-step explanation: got it right on edge :)
On a cube there are 6 sides. There are three odd numbers and one 4, so the probability of rolling these numbers is 4/6 which is 2/3. To get the probability of it from two rolls, we multiply it by itself once because it is being rolled once more. 2/3 x 2/3 is 4/9, so the probability of rolling an odd number or four in two roles is 4/9.

Answer:
6.4
Step-by-step explanation:
The given triangle is a Right Angled Triangle with right angle at E.
So, measure of angle E = 90 degrees
measure of angle D = 62 degrees
measure of side FE = 12
We have to find the measure of side DE. Note that side DE is adjacent to Angle D and side FE is opposite to angle D. So we can use tangent ratio to find the measure of DE.

Therefore, the value of DE, rounded to nearest tenth is 6.4
