Answers
The statistic that is most affected by the lowest score is A. the mean
How to determine the most affected statistic?The stem and leaf plot is missing from the question;
However, the question can be solved without it.
The lowest score on the stem and leaf plot is an outlier of the plot.
In statistics, outliers have huge effect on the mean of the dataset and they have little or no effect on the median and mode
This means that, the statistic that is most affected by the lowest score is A. the mean

Find the measure of angle F if angle D = 88°
Answers
Answer:
52
Step-by-step explanation:
Two triangles are similar
m<B = m<E
m<C = m<D
m<A = m<F
now, the sum of interior angles in a triangle is equal to 180
angle B is given as 40 (so angle E is also 40) and angle D is given as 88 to find m<F:
40 + 88 + m<F = 180 add like terms
128 + m<F = 180 subtract 128 from both sides
m<F = 52

Find the exact length of side a.
Answers
The exact length of a which is equivalent to BC is 7units
Cosine ruleA triangle is a shape with 3 sides and angles. In order to determine the sides BC, we will use the cosine rule
c² = a² + b² - 2abcosC
Given the following parameters
b = 2
c = 5√3
theta = 30 degrees
Substitute
c² = 2² + (5√3)² - 2abcos30
c² = 4 + 75 - 2(2)(5√3)*√3/2
c² = 79 - 30
c² = 49

What is the ratio of the area of sector abc to the area of sector dbe? a. b. c. d. e.
Answers
The ratio of the area of sector abc to the area of sector dbe is 4/3
How to determine the ratio of the areas?For sector abc, we have:
Angle = x
Radius = 2r
For sector dbe, we have:
Angle = 3x
Radius = r
The area of a sector is:
[tex]Area =\frac{\theta}{360}* \pi r^2[/tex]
So, we have:
[tex]ABC =\frac{x}{360}* \pi (2r)^2[/tex]
Evaluate
[tex]ABC =\frac{x* \pi r^2}{90}[/tex]
For DBE, we have:
[tex]DBE =\frac{3x}{360}* \pi (r)^2[/tex]
Evaluate
[tex]DBE =\frac{x}{120}* \pi r^2[/tex]
The ratio of both areas is:
[tex]Ratio = \frac{x}{90}* \pi r^2 : \frac{x}{120}* \pi r^2[/tex]
Cancel out the common factors
[tex]Ratio = \frac{1}{90} : \frac{1}{120}[/tex]
Express as fraction
[tex]Ratio = \frac{120}{90}[/tex]
Divide
[tex]Ratio = \frac{4}{3}[/tex]
Hence, the ratio of the area of sector abc to the area of sector dbe is 4/3

Now you have the hypotenuse of the triangle on the left notice that the hypotenuse we just solved for is actually a leg for the triangle on the right. Now you can use the hypotenuse formula for x.
10.3^2 + 4^2 = x^2 -> 106.09 + 16 = x^2

Are the equations 6x-6=3x and x-1=3x equivalent?
Answers
Answer:
No, they aren't the same (equivalent).
Step-by-step explanation:
First, solve for both equations:
Equation #1: 6x-6=3x
Simplifying
6x + -6 = 3x
Reorder the terms:
-6 + 6x = 3x
Solving
-6 + 6x = 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-6 + 6x + -3x = 3x + -3x
Combine like terms: 6x + -3x = 3x
-6 + 3x = 3x + -3x
Combine like terms: 3x + -3x = 0
-6 + 3x = 0
Add '6' to each side of the equation.
-6 + 6 + 3x = 0 + 6
Combine like terms: -6 + 6 = 0
0 + 3x = 0 + 6
3x = 0 + 6
Combine like terms: 0 + 6 = 6
3x = 6
Divide each side by '3'.
x = 2
Simplifying
x = 2Equation #2: x-1=3x
Simplifying
x + -1 = 3x
Reorder the terms:
-1 + x = 3x
Solving
-1 + x = 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-1 + x + -3x = 3x + -3x
Combine like terms: x + -3x = -2x
-1 + -2x = 3x + -3x
Combine like terms: 3x + -3x = 0
-1 + -2x = 0
Add '1' to each side of the equation.
-1 + 1 + -2x = 0 + 1
Combine like terms: -1 + 1 = 0
0 + -2x = 0 + 1
-2x = 0 + 1
Combine like terms: 0 + 1 = 1
-2x = 1
Divide each side by '-2'.
x = -0.5
Simplifying
x = -0.5A pilot scheduled to depart at 4:00 pm, but due to air traffic, her departure has been delayed by 10 minutes. Air traffic control approved a new flight plan that will allow her to arrive three times faster then she calculated in her original flight plan. Let x represent the time, in minutes, of her original flight. Create an equation that can be used to predict the number of minutes after 4:00 pm she will arrive at her destination.
A. Y = 1/3x + 10
B. Y = 3x + 10
C. Y = 1/3x - 10
D. Y = 3x - 10
Answers
y = (1/3)x+10
=============================================================
Explanation:
x = number of minutes of the original flight
Because the pilot travels 3 times faster than before, it means she travels 1/3 of the original time. If she took x minutes on the original flight, then she will take (1/3)x minutes for the new faster flight.
Then add on the 10 minute delay to end up with (1/3)x+10

The value of x must be 25.0. The correct option is the second option- 25.0
Solving Linear equationsFrom the question, we are to determine the value of x
From the given diagram, we can write that
m ∠SOR + m ∠UOR + m ∠TOU = 180° (Sum of angles on a straight line)
∴ (2x +8)° + (3x - 14)° + (3x -14)° = 180°
2x° + 8° + 3x° -14° + 3x° -14° = 180°
Collect like terms
2x° + 3x° + 3x° + 8° - 14° -14° = 180°
8x° -20° = 180°
8x° = 180° + 20°
8x° = 200°
x = 200/8
x = 25.0
Hence, the value of x must be 25.0. The correct option is the second option- 25.0
