Answer:
×=30⁰ :)
Step-by-step explanation:
x⁰+(x+30⁰)= 90⁰
x⁰+x⁰= 90⁰-30⁰=60⁰
2x⁰=60⁰
60⁰÷2=30⁰ => x⁰=30⁰
verification:
30⁰+(30⁰+30⁰)=90⁰
Volume sphere A V1 = (4/3)πR³
R=∛((3/4)V1/π)
Volume sphere B V2= (4/3)πr³
r=∛((3/4)V2/π)
R-r = ∛((3/4)40/π) - ∛((3/4)10/π) ≈ 0.8 inch
Answer C. 0.8 inch.
Answer:
The 68% confidence interval for the population proportion of college seniors who plan to attend graduate school is (0.16, 0.24).
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
.
A recent survey showed that among 100 randomly selected college seniors, 20 plan to attend graduate school and 80 do not.
This means that 
68% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The 68% confidence interval for the population proportion of college seniors who plan to attend graduate school is (0.16, 0.24).
Selection A is appropriate.
_____
The black dot on the graph means that one of the regions of interest will be
x ≤ 1
The y-intercept for the left branch of the graph is -4, so we khow that
y = x³ -4, x ≤ 1
will be part of the function definition.
