Mack, Jason, and Yuri invested a total of $14,500 in the stock market. After one year, they earned a profit equal to 1/5 of their investment Mack receives 2/5 of the profit, Jason Receives 1/4 of the profit, and Yuri receives the rest of the profitWhat is the amount of each person's profit?
Answer:
The amount of each person's profit is:
Mack
= $1160
Jason
= $725
Yuri
= $1015
Step-by-step explanation:
Mack, Jason, and Yuri invested a total of $14,500 in the stock market. After one year, they earned a profit equal to 1/5 of their investment Mack receives 2/5 of the profit, Jason Receives 1/4 of the profit, and Yuri receives the rest of the profitWhat is the amount of each person's profit?
Step 1
We calculate how much the profit is.
Mack, Jason, and Yuri invested a total of $14,500 in the stock market. After one year, they earned a profit equal to 1/5 of their investment
The profit = 1/5 of Investment
Hence = 1/5 × $14500
Profit = $2900
Step 2
We calculate the amount each of them receives.
Mack receives 2/5 of the profit,
= 2/5 × $2900
= $ 1160
Jason Receives 1/4 of the profit
= 1/4 × $2900
= $725
Yuri receives the rest of the profit
This is calculated as:
$2900 -($1160 + $725)
$2900 - $1885
= $1015
The amount of each person's profit is:
Mack
= $1160
Jason
= $725
Yuri
= $1015

Alice, Bob, and Carl arrange to meet for lunch on a certain day. They arriveindependently at uniformly distributed times between 1 pm and 1:30 pm on that day.
Required:
a. What is the probability that Carl arrives first?
b. What is the probability that Carl will have to wait more than 10 minutes for one of the others to show up?
c. What is the probability that Carl will have to wait more than 10 minutes for both of the others to show up?
d. What is the probability that the person who arrives second will have to wait more than 5 minutes for the third person to show up?
Answer:
a. What is the probability that Carl arrives first?
Probability that Carl arrives first is ¹/₃ = 33.33% since their arrival times is uniformly distributed. The same probability applies to Bob and Alice.
b. What is the probability that Carl will have to wait more than 10 minutes for one of the others to show up?
Assuming that Carl arrived on time, 1:10 PM, we must determine the probability that Alice or Bob arrive between 1:20 and 1:30 (half the remaining time)
P = [3 · (¹/₂ - ¹/₃)] · [3 · (¹/₂ - ¹/₃)] = (3 · ¹/₆) · (3 · ¹/₆) = ¹/₂ · ¹/₂ = ¹/₄ = 25% chance that either Alice or Bob arrive more than 10 minutes later
c. What is the probability that Carl will have to wait more than 10 minutes for both of the others to show up?
P = 1 - 25% = 75%
d. What is the probability that the person who arrives second will have to wait more than 5 minutes for the third person to show up?
I divided the 20 minutes by 5 to get ¹/₄:
P (|S - T| ≤ ¹/₄) = {[(x + ¹/₄)²] / 2} + (1 / 2x) + {[(⁵/₄ - x)²] / 2} = 0.09375 + 0.25 + 0.09375 = 0.4375 = 43.75%

Find the equation of the line that is parallel to the
line y = -X- 7 and passes through the point
(-5, – 7). Write the equation in slope-intercept
form.
9514 1404 393
Answer:
y = -x -12
Step-by-step explanation:
The slope of the line you want is the same as the slope of the line you have: -1. Then the point-slope equation of the line is ...
y -k = m(x -h) . . . . . . line of slope m through point (h, k)
y -(-7) = -1(x -(-5))
y = -x -5 -7 . . . . subtract 7, eliminate parentheses
y = -x -12 . . . slope-intercept equation

Question: What additional information is needed to prove that triangles ABC and EFG are congruent by the SSS triangle congruence theorem?
A. AB = EG, FH = AC, EF = BC
B. AB = BC, BC =FG, and FG = EG
C. AB = EG, FH = AC, EF = BC
D. BC = EG, FH = EF, AC = BC
Answer:
NOTE: NONE OF THE OPTIONS GIVEN IS CORRECT. THIS IS THE CORRECT ANSWER.
AB = EF, BC = FG, AC = EG
Step-by-step explanation:
According to the SSS Congruence statement, for ∆ABC to be congruent to ∆EFG, all the sides of ∆ABC must be congruent to all the corresponding sides of ∆EFG.
This means that:
AB must be congruent to EF
BC must be congruent to FG
AC must be congruent to EG
Therefore, additional information is needed to prove that triangles ABC and EFG are congruent by the SSS triangle congruence theorem are:
AB = EF, BC = FG, AC = EG

A data set includes 40 pulse rates of men, and those pulse rates have a mean of 67.3 beats per minute and a standard deviation of 10.3 beats per minute. Construct a 99% confidence interval estimate of the standard deviation of the pulse rates of men.a) 8.4 beats per minute
Answer:
The 99% confidence interval of the standard deviation of the pulse rates of men is
[tex][ 7.949 \ \ , \ 14.387 ][/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 40
The mean is [tex]\= x = 67.3 \ beats \ per \ minute[/tex]
The standard deviation is [tex]s = 10.3 \ beats \ per \ minute[/tex]
Generally the degree of freedom is mathematically represented as
[tex]df = n- 1[/tex]
=> [tex]df = 40- 1[/tex]
=> [tex]df = 39[/tex]
From the question we are told the confidence level is 99% , hence the level of significance is
[tex]\alpha = (100 - 99 ) \%[/tex]
=> [tex]\alpha = 0.01[/tex]
Generally from the chi distribution table the critical value of at a degree of freedom of is
[tex]X^2 _{\frac{\alpha }{2} , 39} = 65.476[/tex]
Generally from the chi distribution table the critical value of at a degree of freedom of is
[tex]X^2 _{1- \frac{\alpha }{2} , 39} = 19.996[/tex]
Generally the 99% confidence interval of the standard deviation of the pulse rates of men is mathematically represented as
[tex]s \sqrt{\frac{n- 1}{X^2_{1- \frac{\alpha }{2} , n-1} } }\ \ , \ s \sqrt{\frac{n- 1}{X^2_{\frac{\alpha }{2} , n-1} } }[/tex]
=> [tex]10.3 \sqrt{\frac{40- 1}{65.476} }\ \ , \ 10.3 \sqrt{\frac{40- 1}{19.996} }[/tex]
=> [tex][ 7.949 \ \ , \ 14.387 ][/tex]

Solve the following equation. Only enter the numeric answer (no variables). 30=2.5(10-2x)
Answer:
x = -1
Step-by-step explanation:
30 = 2.5(10)(-2x) - you multiply by each
30 = 25 - 5x - then pass 25 to the other side and subract
5x = - 5x - then divide 5 / -5
x = -1 - and you have the answer
Answer:
x= -1
Step-by-step explanation:
distribute 2.5 through the parenthese
30=25-5x
move variable to the left hand side an change its sign
5x+30 =25
move constant to the right hand side and change the sign
5x=25 -30
calculate the difference
5x= -5
divide both sides of the equation by 5
x= -1

Write 34/7 as a mixed number in simplest form
Answer:
4 6/7
Step-by-step explanation:
34/7
We finds out how many 7s are in 34
5 * 7 is 35, so it must be 4.
when 34 is divided by 7, the answer would be 4 and 6 remainders.
put the remainders back into the nominator part of the fraction.
so it's 4 6/7
What is the value of a2+c•(2+b)
when a =3 , b=6 and c=5
Answer:
46 is the answer
Step-by-step explanation:
Because:
a2 + c(2+b)
3(2) + 5(2+6)
6 + 5(8)
6 + 40
46
Answer:
49
Step-by-step explanation:
a² + c(2+b) = a² + 2c+bc
Expand first.
a² + 2c+bc = 3² + 2(5) + 6×5
Substitute a, b and c with actual values.
3² + 2(5) + 6×5 = 9 + 10 + 30
Evaluate.
9 + 10 + 30 = 49
Simplify.
Consider the points below. P(2, 0, 2), Q(−2, 1, 4), R(7, 2, 6)
Required:
Find a nonzero vector orthogonal to the plane through the points P, Q, and R.
Answer: the vector orthogonal is ( 0, 26, -13 )
Step-by-step explanation:
Given that;
P(2, 0, 2), Q(−2, 1, 4), R(7, 2, 6)
PQ = Q - P = (−2, 1, 4) - (2, 0, 2) = (-4, 1, 2)
PR = R - P = (7, 2, 6) - (2, 0, 2) = ( 5, 2, 4)
SO
orthogonal vector = PQ × PR
= ║ i j k
-4 1 2 = i(1×4 - 2×2) + j(5×2 - (-4×4)) + k(-4×2 - 5×1) = 0i + 26j - 13k
5 2 4 ║
= ( 0, 26, -13 )
Therefore the vector orthogonal is ( 0, 26, -13 )

Arnold is planning on painting a mural. Before painting the mural, Arnold painted the picture on a paper that is 5 inches wide and 11 inches tall. Arnold is using a scale in which 12 inch represents 1 foot to paint the mural.
How wide and tall will the actual mural be?
Drag and drop the height and width of the actual mural into the boxes.
Mural Height Mural Width
2.5 ft5.5 ft10 ft22 ft
Answer:
0.42 ft
0.92 ft
Step-by-step explanation:
Width of mural on painting = 5 inches
Height of mural on painting = 11 inches
12 inches of the painting represents 1 foot of the mural
1 inch of the painting represenets [tex]\dfrac{1}{12}[/tex] foot of the mural.
[tex]5\ \text{inches}=5\times \dfrac{1}{12}=0.42\ \text{ft}[/tex]
[tex]11\ \text{inches}=11\times\dfrac{1}{12}=0.92\ \text{ft}[/tex]
The width of the mural is 0.42 ft and height of the mural is 0.92 ft.
The height and width of the actual mural into the boxes is 0.92 ft and 0.42 ft.
Calculation of the height and width:Since
Arnold painted the picture on a paper that is 5 inches wide and 11 inches tall. Arnold is using a scale in which 12 inch represents 1 foot to paint the mural.
So here the width should be 5 of 1 by 12 should be 0.42 feet
And, the height should be 11 of 1 by 12 should be 0.92 ft.
Hence, The height and width of the actual mural into the boxes is 0.92 ft and 0.42 ft.
