It is believed that 36% of the US population has never been married, 32% are divorced, 27% are married, and 5% are widowed. You
Katena32 [7]

Answer: the smallest number of people required for the sample to meet the conditions for performing inference is 100

Step-by-step explanation:

Given that;

36% of US population has never been married

32% are divorced

27% are married

5% are widowed

Taking a simple random sample of individuals to test this claim;

we need expected count in each cell to be at least 5, here the smallest proportion is 5% = 0.05

so we only need to satisfy condition for its expected count;

n × 0.05 ≥ 5

n = 5 / 0.05 = 100

Therefore the smallest number of people required for the sample to meet the conditions for performing inference is 100

An investor bought an antique table for $6000. He paid 5% as a deposit and borrowed the remainder from a bank for two years at 1
Sloan [31]

First lets get rid of the deposit.
(0.95*6000)=5700

Formula is I=PRT
I= Interest earned
P=Principal amount (5700)
R=Rate (18% or 0.18 or 18/100)
T=Time period (2 years)
Equation:
I= 5700*2*0.18
I= 2052
But remember the question asks for monthly payments!
2052/24            (12 months in a year and  T= 2 years)

Which of the following polynomials has solution that are real numbers ?
slava [35]
I think that the only polynomial that has a solution that are real numbers is:

B) x² + 4x + 3 = 0
(x + 3) (x + 1) → x² + 1x + 3x + 3 → x² + 4x + 3

(x+3) = 0 → x = -3

(x + 1) = 0 → x = -1

Real numbers are number that are whole numbers, rational and irrational numbers, positive and negative numbers, and even zero.
