Answer:
60°
Step-by-step explanation:
Jenny drew a figure in art school and the figure is shown in the attached diagram.
The diagram is a regular hexagon and it has rotational symmetry.
Two of its sides is placed parallel to the x-axis.
Therefore, by rotating 60° the adjacent sides will become parallel to the x-axis and the figure remains the same and symmetric with respect to the coordinate axes. (Answer)
Answer:
A sample of 1077 is required.
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 of:

42% of freshmen do not visit their counselors regularly.
This means that 
98% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
How large of a sample size is required?
A sample size of n is required, and n is found when M = 0.035. So






Rounding up:
A sample of 1077 is required.
So,
Since this is independent probability, the probability of the event above occurring is:

First, the probability of landing on heads.

Now, the probability of rolling an even number.
<u />

Plug it into the equation.

The correct option is C.
4 I think because you subtract all since it's 60 min
