The average of 5 distinct scores has the same value as
the median of the 5 scores. The sum of the 5 scores is
420. What is the sum of the 4 scores that are NOT the
median?
Answers
Answer: 336 is the sum of the non-median scores
Step-by-step explanation: if the sum of 5 scores is 420, the average is 420/5 = 84
That is also the median to be subtracted: 420-84= 336

Step-by-step explanation:
Let the points be A and B
A ( 1 , -5 ) [tex]\longrightarrow[/tex] ( x1 , y1 )
B ( 4 , 1 ) [tex]\longrightarrow[/tex] ( x2 , y2 )
Finding the slope :
Slope = [tex]\frac{y2-y1}{x2-x1}[/tex]
Slope = [tex]\frac{1 - ( -5 )}{4 - 1}[/tex]
Slope = [tex]\frac{1+5}{4-1}[/tex]
Slope = [tex]\frac{6}{3}[/tex]
Slope = [tex]2[/tex]

Mary is twice as old as Helen’s age, If 8 is subtracted from Helen’s Age and 4 is added to Mary Age? Mary will be 4 times as old as Helen. What are the ages
Answers
Answer:
set mary is x years old, and helen is y years old.
first sentence:x=2y
second one:4(y-8)=x+4
bring x=2y in 4(y-8)=x+4
=>4y-32=2y+4
=>2y=36
=>y=18
=>x=36
mary:36
helen:18
We want to write and solve a system of equations that models given situation. We will see that Helen is 18 years old, and Mary is 36 years old.
Let's define the variables we will be using.
m = Mary's age.h = Helen's age.We know that "Mary is twice as old as Helen’s age"
Then:
m = 2*h
"If 8 is subtracted from Helen’s Age and 4 is added to Mary Age, Mary will be 4 times as old as Helen."
(m + 4) = 4*(h - 8)
Then the system of equations is:
m = 2*h
(m + 4) = 4*(h - 8)
To solve it, we can replace m by 2*h in the second equation, so we get:
(2h + 4) = 4*(h - 8)
2*h + 4 = 4*h - 32
4 + 32 = 4*h - 2*h
36/2 = h = 18
And we know that:
m = 2*h = 2*18 = 36
So Helen is 18 years old, and Mary is 36 years old.

Since the integral has an infinite discontinuity, it is a Type 2 improper integral. The integral is a proper integral. (b) [infinity] 1 1 + x3 dx 0 Since the integral has an infinite interval of integration, it is a Type 1 improper integral. Since the integral has an infinite discontinuity, it is a Type 2 improper integral. The integral is a proper integral. (c) [infinity] x2e−x2 dx −[infinity] Since the integral has an infinite interval of integration, it is a Type 1 improper integral. Since the integral has an infinite discontinuity, it is a Type 2 improper integral. The integral is a proper integral. (d) π/4 cot(x) dx 0 Since the integral has an infinite interval of integration, it is a Type 1 improper integral. Since the integral has an infinite discontinuity, it is a Type 2 improper integral. The integral is a proper integral.
Answers
Answer:
a
Since the integral has an infinite discontinuity, it is a Type 2 improper integral
b
Since the integral has an infinite interval of integration, it is a Type 1 improper integral
c
Since the integral has an infinite interval of integration, it is a Type 1 improper integral
d
Since the integral has an infinite discontinuity, it is a Type 2 improper integral
Step-by-step explanation:
Considering a
[tex]\int\limits^4_3 {\frac{x}{x- 3} } \, dx[/tex]
Looking at this we that at x = 3 this integral will be infinitely discontinuous
Considering b
[tex]\int\limits^{\infty}_0 {\frac{1}{1 + x^3} } \, dx[/tex]
Looking at this integral we see that the interval is between [tex]0 \ and \ \infty[/tex] which means that the integral has an infinite interval of integration , hence it is a Type 1 improper integral
Considering c
[tex]\int\limits^{\infty}_{- \infty} {x^2 e^{-x^2}} \, dx[/tex]
Looking at this integral we see that the interval is between [tex]-\infty \ and \ \infty[/tex] which means that the integral has an infinite interval of integration , hence it is a Type 1 improper integral
Considering d
[tex]\int\limits^{\frac{\pi}{4} }_0 {cot (x)} \, dx[/tex]
Looking at the integral we see that at x = 0 cot (0) will be infinity hence the integral has an infinite discontinuity , so it is a Type 2 improper integral

In a group of students, 30 played chess, 19 played volleyball, 25 played
basketball, 14 played both volleyball and chess, 8 played both baskethall
and volleyball, 15 played both basketball and chess and 5 played both
three events. How many played chess only, basketball only and volleyball
only? How many students are there in all?
Answers
Answer:
Explained below.
Step-by-step explanation:
Denote the events as follows:
C = chess
V = volleyball
B = basketball
The data provided is as follows:
n (C) = 30
n (V) = 19
n (B) = 25
n (C ∩ V) = 14
n (B ∩ V) = 8
n (B ∩ C) = 15
n (C ∩ V ∩ B) = 5
Consider the Venn diagram below.
The number of students who played only chess is marked in pink:
n (Only C) = 6
The number of students who played only volleyball is marked in blue:
n (Only V) = 2
The number of students who played only basketball is marked in orange:
n (Only B) = 7
The number of students who played all three is marked in grey:
n (C ∩ V ∩ B) = 5

Amy earns $12.50 per hour at her work. She uses the equation shown to calculate the number of hours, she worked last week
12.5h = 312.5 how many hours did Amy work last week?
Answers
Answer:
25
I hope this helps.
Answer:
Amy worked 25 hours
Step-by-step explanation:
To first start off we have the equation 12.5h= 312.5
from here, we divide by 12.5 to have h by itself inorder to find how many hours she worked as h stands for hours.
Once you divide 312.5 by 12.5 you get h=25
Once again, the h stands for hours, so this means that Amy worked 25 hours, and that for one hour she earned 12.5 dollars.
If you want to find how much money she made for example in 5 hours, all you have to do is plug in the 5 for h and multiply it by 12.50 to get how much she earned in that certain amount of hours!
Hope this helps! If you have any questions, feel free to ask! :)

You can use this to check each of the answers in your formula, like this:
if x=6, then:
x^2 < 100
6 x 6 = 36
36 < 100

A landscaper needs to estimate the amount of material required for a project building a circular brick patio for a client. The diameter of the patio is 13m and one bundle of brick will cover 116ft^2. How many bundles does he need?
Answers
Answer:
13 bricks
Step-by-step explanation:
Given parameter:
Diameter of the patio = 13m
Area of one bundle of brick = 116ft²
Unknown:
The number of bricks that will cover the patio = ?
Solution:
To solve this problem, we must find the area of the patio first.
Area of the patio = π r²
r is the radius of the patio;
Radius = [tex]\frac{13}{2}[/tex]
So area = π x ( [tex]\frac{13}{2}[/tex]) ² = 132.75m²
Now, let us convert the Area of the brick from ft² to m²;
1ft² = 0.093m²
116ft² = 0.093 x 116 = 10.79m²;
The number of bricks required to cover the patio = [tex]\frac{132.75}{10.79}[/tex] = 12.3 bricks,
Realistically, about 13 bricks would be needed.
Jade and Jackson are considering a $210,000 mortgage for 30 years at 5.7%. With this information, their monthly payment would be $1218.84.
If they make only the minimum payment each month, what is the total payback of this loan?
How much of this total payback is interest?
Answers
Answer:
Jade and Jackson
The total payback of this loan = $438,782.72
The interest of this total payback is $228,782.72
Step-by-step explanation:
a) Data and Calculations:
Mortgage = $210,000
Interest rate of mortgage = 5.7%
Monthly payment = $1,218.84
Using an online calculator for Mortgage Payoff, the Original Payoff Schedule is:
Monthly Pay = $1,218.84
Total Payments = $438,782.72
Total Interest = $228,782.72
Answer:
Step-by-step explanation:
1218.84⋅12⋅30=$438,782.40
The total interest paid is the total payback less the amount borrowed.
$438,782.40−$210,000=$228,782.40
