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

Solve the equation 1) 4.3^x+1 = 27+9^x<br> 2) 3^x+5= 3^x+3+8/3
Bad White [126]

Answer:

Step-by-step explanation:

4*3^x+1=27+(3^2)^x

(3^2)^x=(3^x)^2

3^x=t

4t+1=27+t^2

t^2-4t+27-1=0

t^2-4t+26=0

delta=4^2-4*1*26=16-84=-68<0

the  equation has not real solutions

A square patio has an area of 200 square feet. How long is each side of the patio to the nearest tenth?
Darya [45]
If patio is square it means that area of if is A=a^2 where a is one side
Now we can substitute A=200 and solve eq
a^2=200
a=\sqrt{200}
a=14.1421
Now we are rounding to the nearest tenths
a=14.1 because next number is 4 and is less then 5.
The result is 14.1
