Answer:
50°
Step-by-step explanation:
In the figure attached, the plot of the problem is shown.
Assuming that segments DE and CF are parallel then the following angles are congruent:
∠DEG ≅ ∠CFG
∠CGF ≅ ∠DGE
∠GCF ≅ ∠GDE
As a consequence, ∠DEG = 50°

Steps:
Boys: 30+40+50+60+60+70+70+70+80+80+80+90+90+100 = 970
Girls: 10+20+50+50+60+70+70+80+80+80+90+100 = 760
THEN Divide the sum of boys and girls but how many numbers you added
970 ÷ 14 = 69.2
910 ÷ 12 = 63.3
If the radius of a circle is multiplied by 3, which is true?
Answer:
I think that both are true...
If it's one, it's the circumference.
Step-by-step explanation:
So say the radius is x.
The area is πx^2
The circumference is 2xπ
If you multiply it by 3:
The area is 3πx^2
The circumference is 6xπ
Answer:
The circumference is tripled
Step-by-step explanation:
If the radius started as 2 the area would be 12.57 and the circumference would be 12.57.
Then if multiply the radius by 3 it would be 6 and the area would be 113.1 and the circumference would be 37.7.
12.57x3=37.7
Therefore the circumference triples when the radius is multiplied by 3.

PLS HELP!!!!!! In a survey of 4530 U.S. adults, 87% said that they would like to donate more to charity. What is the margin of error for the survey? Round to the nearest tenth of a percent
Answer:
Margin of Error = 1.0% to the nearest tenth of a percent.
Step-by-step explanation:
Margin of Error is the width of the confidence interval about the mean.
It is given mathematically as,
Margin of Error = (Critical value) × (standard Error)
Critical value is obtained from the z-tables at the popular confidence level of 95% and z-tables is used because the sample size, 4530, is large enough to approximate the population properties.
Critical value = 1.960
Standard error = σₓ = √[p(1-p)/n]
p = 87% = 0.87
n = sample size = 4530
σₓ = √[0.87×0.13)/4530]
= 0.0049966876
Margin of Error = 1.96 × 0.0049966876 = 0.0097935078 = 0.00979 = 0.979% = 1.0% to the nearest tenth of a percent.

Will give brainliest answer
Answer:
d = 13 cm
r = 6.5 cm
Step-by-step explanation:
The diameter is the distance from side to side going through the center
d = 13
The radius is 1/2 of the diameter
r = d/2 = 13/2 = 6.5 cm

What is the sample space for a 5 sided number cube?
Answer:
{1, 2, 3, 4, 5}
Step-by-step explanation:
Sample space is the set of all possible outcomes. Supposing that the 5 sided number cube has numbers one to five on its sides, the possible outcomes are the numbers that can be rolled, then its sample space is: {1, 2, 3, 4, 5}
A polygon is shown:
The area of polygon MNOPQR = Area of a rectangle that is 9 square units + Area of a rectangle that is ___ square units. (Input whole numbers only, such as 8.) (5 points)
Answer: 4
We're talking about the right part.
OP = RQ - NM = 7 - 3 = 4
PQ = MR - NO = 3 - 2 = 1
Area(OPQ?) = 4×1 = 4
Answer: 4
The area of polygon MNOPQR = Area of a rectangle that is 9 square units + Area of a rectangle that is 4 square units.
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
The area of a rectangle = L × W
Where W is the width of the rectangle and L is the length of the rectangle
A polygon is given in the question, as shown
The area of polygon MNOPQR = Area of a rectangle that is 9 square units + Area of a rectangle that is ___ square units.
We have to determine the fill-in-the-blank.
As per the given figure, we can see that
OP = RQ - NM = 7 - 3 = 4
PQ = MR - NO = 3 - 2 = 1
Required area of rectangle = 4 × 1 = 4
Hence, the required fill-in blank will be "4".

Which residual plots indicate that the original data set has a linear relationship? Check all that apply
Answer: A, B and E
Step-by-step explanation:
A residual values should be equally and randomly spaced around the horizontal axis. If the plot looks like any of the images in C and D, then the data set is probably not a good fit for regression. A non-linear pattern is more appropriate.

How to solve
3x+y=9
5x+4y=22
Answer:
(2, 3) x=2, y=3
Step-by-step explanation:
There are two ways to solve this: substitution & elimination:
Using substitution for this equation:
[tex]\left \{ {{3x+y=9} \atop {5x+4y=22}} \right.[/tex]
3x + y =9
y = 9-3x
Substitute for y:
5x + 4(9 - 3x) = 22
5x + 36 - 12x = 22
-7x = -14
x = 2
Solve for y:
3(2) + y = 9
6 + y = 9
y = 3

Which expression represents the growth of an investment of $1,500 at 12% per year for a period of t years?
A. 1500(12)t
B. 1500(0.12)t
C. 1500t1.12
D. 1500(1.12)t
Answer:
B
Step-by-step explanation:
The investment grows by 12 percent every year. Therefore, if you multiply the 1500 by 0.12 you should get the value of the amount of extra money made in one year. If you substitute 2 into t you get the value increased by year 2 and so on.

Aisha is playing a game in which she can gain or lose points on each turn. The table below
shows the points she scores on each of four turns in the game.
Aisha states that her highest score is on Turn 3, because 16 is greater than 3, 10, or 9. Use the
drop-down menus to explain Aisha's mistake.
Answer:
A score of -16 represents the lowest of points for these four turns.
The number for Aisha's highest score will be turn 2 on the number line.
That number is 10.
Step-by-step explanation:
Since the options of the drop down menu are not included, you should choose any option similar to lowest.
Aisha's highest score was obtained in turn 2 and that is 10.
Aisha is comparing absolute terms, that is why she believes that -16 represents a good score, while in reality is the worst she got.

Which year had a decrease in profit between months 3 and 4?
Last year
This year
Step-by-step explanation: last year
Answer:
Last Year
Step-by-step explanation:
If you take a look at the red and blue lines in between the numbers 3 and 4 at the bottom of the graph, you can see that the profit for the red line (last year) is decreasing while the profit for the blue line (this year) is increasing. Last year (red line) had a decrease in profit between months 3 and 4.
What is the solution to the equation?
2/3a - 1/6 = 1/3
Answer:
a in this equation would be 3/4 because...
Step-by-step explanation:
2/3a−1/6=1/3
2/3a+−1/6=1/3
2/3a+−1/6+1/6=1/3+1/6
2/3a=1/2
Multiply both sides by 3/2.
(3/2)*(2/3a)=(3/2)*(1/2)
a=3/4

The graph is a linear and straight line so option (B) will be correct.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
In another word, a linear function is a function that varies linearly with respect to the changing variable.
Given graph is ;
y = 2x - 3
The slope of any function is given by;
dy/dx
So,
d(2x - 3)/dx = -2
Since the slope is constant that it will be a straight line and the straight line curve is a linear function because it has a degree of 1.
Hence "The graph is a linear and straight line".

Answer:
Step-by-step explanation:
In the first case the function could become undefined as x approaches -3 or 3 from either direction. The vertical asymptotes are x = -3 and x = +3.
In the second case, there's only one vertical asymptote, because the denominator can be zero (0) only at x = 0.
What is the experimental probability of rolling a number less than 3?
Answer:
The probability of rolling a number less than 3 (so, 1 or 2) is 2 out of 6, or 1/3. The odds are 4 to 2 against, or 2 to 1 against.
Step-by-step explanation:
If so, there are two numbers less than 3: 1 and 2. There are 6 total possible results, so the probability of rolling a number less than 3 is 26 or 13 or 0.3333

Step-by-step explanation:
Consider the ratios of corresponding sides
[tex]\frac{PQ}{QR}[/tex] = [tex]\frac{30}{15}[/tex] = 2
[tex]\frac{PT}{QS}[/tex] = [tex]\frac{20}{10}[/tex] = 2
[tex]\frac{QT}{RS}[/tex] = [tex]\frac{28}{14}[/tex] = 2
Since the ratios of corresponding sides are equal, then
Δ PQT and Δ QRS are similar by the SSS postulate
