Answer:
Step-by-step explanation:
The area for the sector of a circle is
[tex]A_s=\frac{theta}{360}*\pi r^2[/tex] where theta is the measure of the central angle. We have some given values to fill in:
Area is 64π and the central angle is 90°, so all we have left to find is the radius. Filling into the equation:
[tex]64\pi =\frac{90}{360}*\pi r^2[/tex]
Let's get that solved for r-squared first:
[tex]\frac{360(64\pi )}{90\pi } =r^2[/tex]
Doing all the math on that gives us:
[tex]256=r^2[/tex]
Take the square root of both sides and get that r = ±16. BUT we know that lengths cannot be negative, so we disregard the -16 and say that the radius is 16 inches.

Helen puts 50 marbles into 9 jars. First, she puts in the greatest
possible number of marbles into each of the 1st 8 jars. Each of these
8 jars has an equal number of marbles. The remaining marbles are
then put into the 9th jar. How many more marbles does she need for
the 9th jar such that every jar has the same number of marbles?
Answer:
She needs 4 more marbles for the 9th jar.
Step-by-step explanation:
Multiples of 8:
M = {0, 8, 16, 24, 32, 40, 48, 56, ...}
First, she puts in the greatest possible number of marbles into each of the 1st 8 jars.
The total is the greatest multiple of 8 below 50, which is 48.
In each jar:
48/8 = 6
The remaining marbles are then put into the 9th jar.
50 - 48 = 2 in the 9th jar.
How many more marbles does she need for the 9th jar such that every jar has the same number of marbles?
All others have 6, the 9th has 2.
6 - 2 = 4
She needs 4 more marbles for the 9th jar.

Step-by-step explanation: the ABC triangle has a 25-degree angle and a 90-degree angle as you can see by the marks. The first triangle has a 25-degree angle and a 90-degree angle as you can see by the marks. The second one does have a 90-degree angle but it's a different shape and has no 25-degree angle. The third one has both angles 25 and 90 but if you look close it's a different shape. The last one does not have a 90-degree angle but it does have a 25-degree angle and it's a different shape.
So it would be the first option.

Suppose they weigh a sample of 20 randomly selected scoops of hazelnut gelato and 15 scoops of dulce de
leche gelato. They will then look at the difference in their sample means (Tu – īp).
What do we know about the shape of the sampling distribution of CH
TD, and why?
Answer:
It's exactly normal, because both populations are normally distributed.

Choose the option that best answers the question. Paracelsus University has two kinds of professors: academic professors and professional professors. At Paracelsus University, 60% of the professors are academic professors, and 70% of the professors are tenured. If 90% of the professors at Paracelsus University are academic professors or tenured or both, then what percent of the professional professors there are tenured
Answer:
75%
Step-by-step explanation:
The computation of the percent of the professional professors there are tenured is shown below;
Given that
academic professors A = 60%
professors tenured P = 70%
professors at Paracelsus University = 90%
Based on the above information
As we know that 90% of the professors could be academic professors or tenured or both
so here we can say that the percent of academic professors is
= 60 + 70 - 90
= 40
Therefore professors tenured will be
= 70 - 40
= 30
Now the percentage of professional professor that is tenured is
= 30 ÷ 40 × 100
= 75%
There are 2 girls for every 3 boys in Mrs. Sanchez' class. If there are 12 boys in the class, how many girls are there?
8 girls are there in Mrs. Sanchez' class.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Based on the given conditions, formulate
2 girls ⇒ 3 boys
X girls ⇒ 12 boys
3X = 12 × 2
⇒ 3X = 24
⇒ X = [tex]\frac{24}{3}[/tex]
⇒ X = 8
Hence, 8 girls are there in Mrs. Sanchez' class.

Answer:
17.9 units is the answer
Step-by-step explanation:
points are (-7,-2) and (9,6)
Pythagorean theorem can be written as,
[tex]d=\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2} \\\\d=\sqrt{9-(-7))^2 + (6-(-2))^2}\\\\d=\sqrt{(16)^2+(8)^2} \\\\d=\sqrt{256+64} \\\\d=\sqrt{320} \\\\d=17.88[/tex]

For each part below, use the figure to fill in the blank.
Answer:
a) m<F = 70
b) AB = 6
Step-by-step explanation:
a)
Since this is an isoceles triangle, the base angles are equal so:
2x + 40 = 180
2x = 140
x = 70
b)
Since all of the angles are equal, this is an equilateral triangle. This also makes all of the sides equal and the same.

A university council wants to determine the need for a new staff room. The council conducted a survey of the staff by randomly speaking to 860 staff members out of 2,844 staff members. The council found that 70% of those surveyed were in favor of building a new staff room. Assuming a 90% confidence level, which statement holds true?
As the sample size is appropriately large, the margin of error is 0.036.
As the sample size is appropriately large, the margin of error is 0.026.
As the sample size is too small, the margin of error is 0.026.
As the sample size is too small, the margin of error cannot be trusted.
To find a margin of error for a sample proportion, these assumptions must be met, where n is the sample size and is the sample proportion.
First rewrite the proportion of positive responses as a decimal number.
Now substitute the sample proportion and the sample size, 860, into the formulas for the assumptions to determine whether they are met.
Both values are greater than 10, so the assumptions are met, and the margin of error can be calculated.
Find the margin of error using this formula, where z is the critical value.
For a 90% confidence level, . Substitute the values of z, n, and into the formula for margin of error and evaluate.
Answer:
As the sample size is appropriately large, the margin of error is 0.026
