In 2010, the average finishing time for marathons across the US was approximately 278 minutes, with a standard deviation of approximately 63 minutes. What finishing time defines the fastest 7.93% of runners?
Answers
Answer:
336 minutes
Step-by-step explanation:
Mean finishing time: 278 minutes
Standard Deviation: 63 minutes
Confidence interval: [278 - 63] , [278 + 63] = [215 , 341] minutes
What finishing time defines the fastest 7.93% of runners?
This means the 7.93% of time closest to the upper limit of 341 minutes
341 - 215 ≡ 63 × 2 = 126
7.93% of 126 = 0.0793 × 126 = 9.9918
341 - 9.9918 = 331.0082
Hence the finishing time that defines the fastest 7.93% of runners has an interval of [331 , 341] minutes with a mean or average of 336.0041 ≅ 336 minutes
The ratio between the ages of Amar and Kabir is 3:4 at present.after 4 years ago their ages would be 7:9.ratio of ages of Kabir and amar after 20 years from now?
Answers
Answer:
[tex]Ratio = 11:13[/tex]
Step-by-step explanation:
Represent Amar age with x
Represent Kabir age with y
So, we have:
Presently
[tex]x : y = 3 : 4[/tex]
After 4 years
[tex]x + 4 : y + 4 = 7 : 9[/tex]
Simplify both ratios:
[tex]x : y = 3 : 4[/tex]
[tex]\frac{x}{y} = \frac{3}{4}[/tex]
Cross Multiply
[tex]4x = 3y[/tex]
Make x the subject
[tex]x = \frac{3}{4}y[/tex]
[tex]x + 4 : y + 4 = 7 : 9[/tex]
[tex]\frac{x + 4}{y + 4} = \frac{7}{9}[/tex]
Cross Multiply
[tex]7(y+4) = 9(x+4)[/tex]
Open Brackets
[tex]7y + 28 = 9x + 36[/tex]
Collect Like Terms
[tex]9x = 7y + 28 - 36[/tex]
[tex]9x = 7y -8[/tex]
Substitute [tex]\frac{3}{4}y[/tex] for x in [tex]9x = 7y -8[/tex]
[tex]9(\frac{3}{4}y) = 7y - 8[/tex]
[tex]\frac{27}{4}y = 7y - 8[/tex]
[tex]6.75y = 7y - 8[/tex]
[tex]6.75y - 7y = - 8[/tex]
[tex]-0.25y = - 8[/tex]
[tex]y = -8/-0.25[/tex]
[tex]y = 32[/tex]
Substitute 32 for y in [tex]x = \frac{3}{4}y[/tex]
[tex]x = \frac{3}{4} * 32[/tex]
[tex]x = \frac{3* 32}{4}[/tex]
[tex]x = \frac{96}{4}[/tex]
[tex]x = 24[/tex]
So, in 20 years time, the ratio of the ages would be:
[tex]x + 20 : y + 20[/tex]
This gives
[tex]24 + 20 : 32 + 20[/tex]
[tex]44 : 52[/tex]
Divide by 4
[tex]44/4:52/4[/tex]
[tex]11:13[/tex]
Hence, the Ratio is
[tex]Ratio = 11:13[/tex]

In kidney transplantations, compatibility between donor and receiver depends on such factors as blood type and antigens. Suppose that for a randomly selected donor from a large national kidney registry, there is a 10% chance that he or she is compatible with a specific receiver. A sample of size 5 donors are randomly selected from this registry. Find the probability that exactly 2 of the selected donors is compatible.
Answers
Answer:
The probability is [tex]P(X = 2)= 0.0729[/tex]
Step-by-step explanation:
From the question we are told that
The percentage that the donor is compactible is p = 0.10
The sample size is n = 5
Generally the probability that the donor is not compactible is
[tex]q = 1- p[/tex]
=> [tex]q = 1- 0.10 [/tex]
=> [tex]q = 0.90 [/tex]
Generally the probability that the exactly 2 of the selected donors is compatible mathematically represented as
[tex]P(X = 2)= \ ^{5}C_2 * p^2 * q^{5-2}[/tex]
Here C standards for combination
=> [tex]P(X = 2)= \ 10 * 0.10^2 * 0.90 ^{5-2}[/tex]
=> [tex]P(X = 2)= 0.0729[/tex]

s congruent to . If angle S is (5x-11) degrees and angle U is (4x+9) degrees, find the value of x.
Answers
Given:
Consider angle S is congruent to angle U.
The angle S is (5x-11) degrees and angle U is (4x+9) degrees,
To find:
The value of x.
Solution:
Since it is given that angle S is congruent to angle U, therefore the measure of theses two angles are equal because measure of congruent angles are equal.
[tex]m\angle S=m\angle U[/tex]
Put the given values.
[tex]5x-11=4x+9[/tex]
Subtract 4x from both sides.
[tex]5x-4x-11=9[/tex]
Add 11 on both sides.
[tex]x=9+11[/tex]
[tex]x=20[/tex]
Therefore, the value of x is 20.
Samuel needs 346 feet of wood to build a fence. The wood comes in lengths of 15 feet.
How many total pieces of wood will Samuel need? Theresa needs twice as many feet of wood as Samuel.
How many pieces of wood does Theresa need?
Samuel needs
pieces of wood. Theresa needs
pieces of wood.
Answers
Length of wood Samuel needs to build a fence = 346 feet
Length of each piece of wood = 15 feet
Number of wood pieces he will have with him :-
[tex] = \frac{346}{15} [/tex]
Samuel will need 23 pieces of wood .
Length of wood Theresa needs to build a fence :-
= 346 × 2
= 692 feet wood
Number of wood pieces Theresa will need :-
[tex] =\frac{692}{15} [/tex]
[tex] = 42 \: pieces \: of \: wood[/tex]
Therefore , Samuel needs 23 pieces of wood and Theresa needs 42 pieces of wood .

Victor has a goal of making $75 per week at his after-school job. Last month he was within $6.50 of his goal. What are the maximum and minimum amounts that Victor might have made last month?
Answers
Answer:
maximum is 81.50
minimum is 68.50
Step-by-step explanation:
1m-751=6.50
m-75=6.50
m=81.50
/m-75=-6.5
m=68.50
The maximum and minimum amounts that Victor might have made last month are $81.5 and $68.5, respectively.
What is Addition?The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.
Given that Victor has a goal of making $75 per week at his after-school job. and Last month he was within $6.50 of his goal. Therefore, the maximum and minimum amounts that Victor might have made last month are,
Maximum and minimum amount = $75 ± $6.50
= $75+$6.50 , $75-$6.50
= $81.5 , $68.5
Hence, the maximum and minimum amounts that Victor might have made last month are $81.5 and $68.5, respectively.

A rental car agency charges a flat fee of $32.00 plus $3.00 per day to rent a certain car. Another agency charges a fee of $30.50 plus $3.25 per day to rent the same car.
Answers
Answer:
a rental car agency charges a flat rate fee of $32.00 plus $3.00 per day to rent a certain car
c = 32 + 3d
another agency charges a fee of $30.50 plus $3.25 per day to rent the same car
c = 30.50 + 3.25d
the number of days for which the cost are the same means
32 + 3d = 30.50 + 3.25d
by solving we find d = 6 days

Answers
Answer:
1596 miles
Step-by-step explanation:
A suitable proportion can be ...
[tex]\dfrac{\text{miles}}{\text{hours}}=\dfrac{M}{14\text{ h}}=\dfrac{342\text{ mi}}{3\text{ h}}\\\\M=\dfrac{14\cdot 342}{3}\text{ mi}=1596\text{ mi}[/tex]
We solved it by multiplying both sides by 14 hours. The units of hours cancel, leaving units of miles.
