Answer:
Part 1) 30%
Part 2) 80 students
Part 3) 57 votes
Part 4) LaToya
Step-by-step explanation:
75 divided by 250 = 0.30 = 30%
32% = 0.32 and then 0.32 times 250 = 80 students
250 - 75 - 80 = 95 students that didn't vote for Carlos or LaToya. Then 0.60 times 95 = 57
LaToya had 80 votes, the most votes.

Answer:
[tex]20 = \frac{Far \ arc - Near \ arc}{2}\\\\20 = \frac{160 - (2m +12)}{2}\\\\40 = 160 - (2m + 12)\\2m + 12 = 160 - 40\\2m = 120 -12\\2m = 108\\m = 54[/tex]
Answer:
m = 54
Step-by-step explanation:
The secant- secant angle 20° is half the difference of the intercepted arcs, that is
[tex]\frac{1}{2}[/tex] (160 - 2m - 12) = 20° ( multiply both sides by 2 to clear the fraction )
- 2m + 148 = 40° ( subtract 148 from both sides )
- 2m = - 108 ( divide both sides by - 2 )
m = 54

Step-by-step explanation:
Answer:20
Step-by-step explanation:
Helpppppp!!!!!!!!!!!!!
============================================================
Explanation:
As the diagram shows, we have a triangular face with a base of b = 18 and height of h = 13. The area of this triangular face is:
A = 0.5*b*h
A = 0.5*18*13
A = 117 square cm or cm^2
This represents the area of one face, but there are 4 identical copies of this triangular face assuming this tetrahedron is a regular polyhedron. So we have a total surface area of 4*117 = 468 cm^2 which points us to choice B
This is the amount of paint you'll need to cover the outer surface of the pyramid, or you can think of it as the amount of wrapping paper needed. This assumes there are no gaps or overlaps.
Assume that a sample is used to estimate a population proportion p. Find the 99.9% confidence interval for a sample of size 247 with 85% successes. Enter your answer as a tri-linear inequality using decimals (not percents) accurate to three decimal places
Answer: [tex]0.791\leq p\leq0.909[/tex]
Step-by-step explanation:
The confidence interval for the population proportion is given by:-
[tex]\hat{p}\pm z^*\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}[/tex], where [tex]\hat{p}[/tex]= sample proportion, n =sample space , z* = critical z-value.
As per given, we have
[tex]n = 247[/tex]
[tex]\hat{p}=0.85[/tex]
Critical value for 99.9% confidence = 2.576
The required confidence interval will be:
[tex]0.85-2.576\sqrt{\frac{0.85\times0.15}{247}}\leq p\leq 0.85+2.576\sqrt{\frac{0.85\times0.15}{247}}\\\\\Rightarrow\ 0.85-(0.058526)\leq p \leq0.85+(0.058526)\\\\\Rightarrow\ 0.791474\leq p\leq0.908526\approx0.791\leq p\leq0.909[/tex]
The required confidence interval: [tex]0.791\leq p\leq0.909[/tex]

Answer:
64
Step-by-step explanation:
height of the hypotenuse:
[tex]\sqrt{60^2-36^2} = \sqrt{3600 - 1296} = \sqrt{2304} = 48[/tex]
36 : height = height : x
36 : 48 = 48 : x
x= 48^2/36 = 64

A random sample of 18 adults, chosen from the 1500 adults in the town, took a survey asking their opinion on a recent property tax change. 25% of those who responded said they were in favor of the change. The company running the survey wants to construct a confidence interval estimating the proportion of all adults in the town who support the change. Which of the conditions for inference have been satisfied?
Answer: Random condition
10% condition
Step-by-step explanation:
The conditions for inference that have been satisfied will be:
• Random condition: This has been satisfied since a random sample of 18 adults were taken from 1500 adults.
• 10% condition: Since 25% of those who responded said they were in favor of the change, then the 10% condition is satisfied.
what does sides of equal length mean
Answer:
equilateral
Step-by-step explanation:
A shape is equilateral if all the sides are the same length. In geometry class, people learn about many shapes, such as triangles and squares. A square is equilateral, because all of its sides are the same length. ... The word equal should help you remember what equilateral means.
Answer:
An isosceles triangle has 2 sides of equal length . The dashes on the lines show they are equal in length. The angles at the base of the equal sides are equal.An equailateral triangle has 3 sides of equal length.

The area of the right triangle shown is 30 ft squared. The segment XY has a length of 5 ft. Find the length of the hypotenuse.
Answer:
Hypotenuse is 13 ft.
Step-by-step explanation:
A=(1/2)bh
30=(1/2)(5)(h)
30=2.5h
h=12 so ZY = 12ft
Then
[tex]a^{2} +b^{2} =c^{2} \\5^{2} +12^{2} =c^{2} \\25+144=c^{2} \\169=c^{2}\\13=c[/tex]

Factor to write an equivalent expression.(What is the Greatest Common Factor?).
−9x+15y
Answer:
GCF is 3
Step-by-step explanation:
Given the expression -9x + 15y
First, we need to find ther individual factors
-9x = -3 *3 * x
15y = 3 * 5 * y
Since 3 is common to both factors
−9x+15y = 3(-3x+5y)
Hence the GCF is 3
What is the volume of a sphere with a radius of 31.6 cm, rounded to the nearest tenth of a cubic centimeter?
Answer:
The answer is 132175.2 cubic centimeters or 1.3 times 10^5 cubic centimeters in scientific notation.
Step-by-step explanation:
To solve for the volume of the sphere, start by using the formula for the volume of a sphere, which is V= [tex]\frac{4}{3}[/tex][tex]\pi[/tex][tex]r^{3}[/tex].
Next, plug in the information given from the question into the formula. The formula will then look like V= [tex]\frac{4}{3}[/tex]([tex]\pi[/tex])([tex]31.6^{3}[/tex]).
Then, simplify and solve for the answer. The final answer is 132175.2 cubic centimeters or 1.3 times 10^5 cubic centimeters in scientific notation.
