remember a coefficient is the number in front of the variable
the coefficient in the fifth term is 9 since 9 is a number.
Answer:
Step-by-step explanation:
A(1,13), B(5,8)
Let C be 7 units to the right of B: C(5+7,8) = C(12,8)
Let D be 7 units to the right of A: A(1+7,13) = A(8,13)

Answer:
The minimum sample size required is 461.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
The margin of error is:

99% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
An interval estimate of the proportion p with a margin of error of 0.06. What is the minimum sample size required?
The minimum sample size required is n, which is found when M = 0.06.
We don't have an estimate for the true proportion, which means that we use
. So






Rounding up
The minimum sample size required is 461.
Answer:
B. 20
Step-by-step explanation:
Cos a = b/c
Cos 53° = b/25
b = 25 × 0,6 = 15
x = √(25² - 15²)
x = √(625 - 225)
x = √400
x = 20
