Answer:
We need a sample size of at least 369.
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:

For this problem, we have that:

90% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
How large of a sample size is required?
We need a sample size of at least n.
n is found when
. So






Rounding up
We need a sample size of at least 369.
The variable z represents how many games that ella played during the season
Answer:
They are similar for their radii, and perimeters have the same ratio: 2
Step-by-step explanation:
The similarity of circles is proved, when we can compare the ratio, between the two radii and the two perimeter and it is the same.
2. The Circle X, has a radius of 6 and the circle Y has the radius of 3.
So let's do it:

3. Now let's check the Perimeters:
4. In addition to this, we can do this Geometrically, by inserting the Circle Y within the Circle X, and if dilate by the scale factor of 2 we'll have these two circumferences coincide.
