Step-by-step explanation:
5v - 4/10 = 4/5

v = (6/5)/5 = 6/25
Answer:
25 units
Step-by-step explanation:
H^2= S1^2 + S2^2
= 15^2 + 20^2
=225 + 400
= 625
= square root of 625
= 25 units
Answer:
Step-by-step explanation:
As sample size increase the variability of the estimate of the proportion would decreases ( reduces)
The formula of variance of the estimator of the proportion is as

Since the denominator of the formula of the variance of sample proportion is n
so as n increase the variance of it decrease.
The center of the estimate of proportion would same
Because 
which does not affect the value of n ( sample size).
Answer:

Step-by-step explanation:

Factor x²-9 and x²-5x+6.

Least common multiple of (x+3), (x-3), (x-2), and (x-3) is (x+3), (x-3), and (x-2).
Adjust the fractions based on LCM.

Subtract the fractions since denominators are equal.

Expand.

The fraction can be in factored form.
