The most obvious and logical answer here is A
Answer:
Standard deviation of the population is 2.4
Step-by-step explanation:
Finishing times of 6 participants in 200 meter dash has been given as 27, 28, 27, 25, 24, 31.
We have to calculate the standard deviation of the population formed by these timings.
Formula of standard deviation is
where = standard deviation
= mean of the data
n = number of scores in the sample
Mean of given data =
=
= 30
Now
= 2.236 ≈ 2.24
Therefore, standard deviation of the given data is 2.24
When we bring 6y from right side to left side it’s sign get changed and 8y-6y=2y.
answer:
Sharon used more milk because 3 cups equal 1.5 (one and a half) pints.
Detailed answer:
1 cup equals 0.5 pints or half of a pint. So if you take 0.5 and multiply it by 3 you get 1.5 and that is the amount of pints that Sharon uses but Sue uses 1 pint or 2 cups. so 1.5 pints is grater than 1 pint by 0.5
(sorry if this was not so clear i am not that good at explaining things, also i hope this helps and you get a good score on whatever you are doing.)
