To find the answer,we can simply multiply 275 by 2-1/2:
275×2-1/2
=275×(2×2+1)/2
=275×5/2
=1375/2
=678-1/2
Therefore, the answer is 678-1/2.
Hope it helps!

Answer:
5.2 inches
Step-by-step explanation:
The diameter of small Nerf balls follows normally distribution with mean 5.2 inches and standard deviation 0.08 inches.
We have to calculate the mean of sampling distribution when 20 balls are selected randomly.
Here, μ=5.2 and σ=0.08.
We know that mean of sampling distribution for mean is equal to the population mean.
mean of sampling distribution for mean= μxbar=μ= 5.2
Thus, mean of the sampling distribution of the sample mean is 5.2 inches
Answer:
1.) 65 2.)73 acute 3.)Obtuse, scalene
In a standard deck of cards, there are a total number of
52 different card. From those 52 cards, 4 cards are numbered as five. Therefore
the probability of selecting a card of five is:
Probability = 4 / 52 = 1 / 13
<span>Assuming that no replacement is made, so the probability
changes with each draw, since the total number of cards decreases from 52 to 51
to 50 and so on. Therefore this is not a simple event.</span>
