hope this answer helps you dear..take care!
for the attached question..option C is correct.
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
Answer:
36
Step-by-step explanation:
simply put x = 4
f(4) = 2(4)² + 4
f(4) = 2 × 16 + 4
f(4) = 32 +.4
f(4) = 36
Answer:
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
When dividing numbers by fractions, we can simply multiply the umber by the reciprocal of the decimal. So,
4 ÷ 1/5 = 4 × (reciprocal of 1/5)
A reciprocal of a number is the same number written under 1. aka, 1 divided by that number, which simply is flipping the numerator and denominator of a number.
So the reciprocal of 1/5 is 5/1 = 5.
So 4 ÷ 1/5 = 4 × 5.
So your answer is 5.
