|5x| < -4 : It is an empty set.
Anything in " | | "(absolute value function) is equal to or greater than zero
B) 0.45 and D) 9/20 are both eqivalent to 45%.
Answer:
25
Step-by-step explanation:
We know that the standard error of the sampling distribution of sample means is
Standard error=standard deviation/√n
√n=standard deviation/Standard error
n=(standard deviation/Standard error)²
We are given that standard deviation=5 and standard error=1. So,
n=(5/1)²
n=5²
n=25.
Thus, the required sample size is 25.
Answer:
x = 20
Step-by-step explanation:
From the Euclidean theorem x^2 = 16 × 25
x^2 = 400
x = 20
I believe if I have done this right the answer will be 1352
