Q: Three runners are training for a marathon. One day, they all run about ten miles, each at their own constant speed. Which of the three runners has the fastest pace? Remember to provide an explanation! :)
Answers
Answer:
runner #1
Step-by-step explanation:
the ratio of distance to time is as shown:
runner 1: 10:1
runner 2: 8.5:1
runner 3: 9:1
because runner #1 has the highest distance to run ratio, that runner has the fastest pace.
Hope this helps :)

If triangle KLM is congruent to NOP,find the perimeter.
Answers
Answer:
Finding x FIRST:
2x-9 = x+5
1x-9 = 5
1x = 14
x = 14
Perimeter = Add all sides
Perimeter of KLM = 15+(2x-9)+8
= 15+(2(14)-9)+8
= 15+(28-9)+8
= 15+19+8

To obtain the graph of y = (x - 8)2, shift the graph of y = x2 units.
Answers
Answer: shift it to the right, 8 units
Step-by-step explanation:
Just did the question aswell
To obtain the graph of y = (x - 8)^2, shift the graph of y = x^2 8 units to the right.
How to work with shifts?We define a horizontal shift of N units for a function f(x) as:
g(x) = f(x + N)
If N is positive, the shift is to the left.If N is negative, the shift is to the right.In this case we have the functions:
g(x) = (x - 8)^2
f(x) = x^2
Comparing these, we can see that:
g(x) = f(x -8)
Meaning that g(x) is a shift of 8 units to the right of y = x^2
Then the complete statement would be:
"To obtain the graph of y = (x - 8)^2, shift the graph of y = x^2 8 units to the right."

3x 32 = 7x + 28
Answers
Answer:
x= 28 /89
Step-by-step explanation:
3x(32)=7x+28
Step 1: Simplify both sides of the equation.
96x=7x+28
Step 2: Subtract 7 from both sides.
96x 7x+28
−7 −7
89x=28
Step 3: Divide both sides by 89.
89x /89 = 28 /89
An individual who has automobile insurance from a certain company is randomly selected. Let Y be the number of moving violations for which the individual was cited during the past 3 years. The pmf of Y is:
y 0 1 2 3
P(y) 0.50 0.25 0.20 0.05
Required:
a. Compute E(Y) and V(3Y−10)
b. Suppose an individual with Y violations incurs a surcharge of $(95Y2−25). Calculate the expected amount of the surcharge.
c. What is the standard deviation of surcharges?
Answers
Answer:
a.
E(y)=0.8
V(3y-10)=7.74
b.
The expected amount of surcharge is 117.5.
c.
The standard deviation of surcharges is 217.6723.
Step-by-step explanation:
a.
y 0 1 2 3
p(y) 0.5 0.25 0.2 0.05
y*p(y) 0 0.25 0.4 0.15
E(y)=sum(y*p(y))=0+0.25+0.4+0.15
E(y)=0.8.
y² 0 1 4 9
y²p(y) 0 0.25 0.8 0.45
V(y)=E(y²)-[E(y)]²
E(y²)=sum(y²*p(y))=0+0.25+0.8+0.45=1.5
V(y)=E(y²)-[E(y)]²
V(y)=1.5-[0.8]²
V(y)=1.5-0.64
V(y)=0.86
V(3y-10)=9V(y)=9*0.86=7.74
V(3y-10)=7.74
b.
E(95Y²-25)=95E(Y²)-25=95*1.5-25=142.5-25=117.5
E(95Y²-25)=117.5
The expected amount of surcharge is 117.5.
c.
SD(95Y²-25)=?
SD(95Y²-25)=√V(95Y²-25)
V(95Y²-25)=95²*V(Y²)
V(95Y²-25)=9025*V(Y²)
V(Y²)=E[(Y²)²]-[E(Y²)]²
y^4 0 1 16 81
y^4*p(y) 0 0.25 3.2 4.05
E[(Y²)²]=sum(y^4*p(y))=7.5
V(Y²)=E[(Y²)²]-[E(Y²)]²
V(Y²)=7.5-[1.5]²
V(Y²)=7.5-2.25
V(Y²)=5.25
V(95Y²-25)=9025*V(Y²)
V(95Y²-25)=9025*5.25
V(95Y²-25)=47381.25
SD(95Y²-25)=√47381.25
SD(95Y²-25)=217.6723
The standard deviation of surcharges is 217.6723.

4. Find the slope and y-intercept.
y= 1/5 x + 4
Answers
Answer:
The slope is [tex]\bold{\frac{1}{5}}[/tex] and the y-intercept is [tex]\bold{4}[/tex].
Step-by-step explanation:
We are given an equation in slope-intercept form (y = mx + b).
In this equation, we can define the following variables:
m = slopeb = y-interceptThe slope in an equation and of a line is the rise over run of a line. The numerator of the fraction will be how many y-coordinates the line will ascend or descend (depending on the sign). The denominator will signify how many x-coordinates the line will move to the left or the right.
The y-intercept is the coordinate at which the line crosses the y-axis. The value of x is 0 and the coordinate can be positive or negative.
Therefore, by looking at our equation, we can see that [tex]\frac{1}{5}[/tex] is the slope, and 4 is the y-intercept.

Write a multiplication equation to determine the number of people, p, who can be invited to the party. How many people can Clancy invite to his party if he needs a serving of yogurt as well?
Answers
Answer:
564 people can be invited to the party
Info-
Total number of cups of yogurt is 423 cups
1 serving = 3/4 pf a cup
Each guest gets 3/4 of a cup or 1 serving
We need to find out how many guests can be invited to the party
Cups : People
3/4 : 1
423 : p
CROSS MULTIPLY
3/4p = 423 times 1
3p = 423 times 4
p= 1,692/3
P would = 564

Given
ΔABC withSlope of AB = -1∠ABC = 90°This means that AB⊥BC
The dilation doesn't affect the shape of the triangle, therefore:
A'B' has slope of -1B'C' ⊥ A'B'Perpendicular lines have negative reciprocal slopes. In other words the product of the slopes is - 1.
Let the slope of B'C' is x, then:
-1*x = -1x = 1Correct option is C
