Answer: d. 1.3333
Step-by-step explanation:
We know that the standard error of a sampling distribution is given by :-
, where = Population standard deviation.
n= Sample size.
AS per given , we have
n=81
Then, the standard error of a sampling distribution with a population standard deviation of 12 and the sample size of 81 will be :-
Hence, the standard error of a sampling distribution with a population standard deviation of 12 and the sample size of 81 is 1.3333.
Thus the correct answer is d. 1.3333 .
<u>Answer:</u>
- The value of x is 35°.
<u>Step-by-step explanation:</u>
<u>We know that:</u>
- ∠3 = 75°
- ∠3 = ∠7 (Corresponding angles)
- ∠7 = x + 40
<u>Work:</u>
- => 75 = x + 40
- => 75 - 40 = x
- => 35 = x
Hence, <u>the value of x is 35°.</u>
Hoped this helped.
