3.6 Triathlon times, Part II: The distribution for triathlon time varies depending on the population you are describing. The distribution for men ages 30 - 34 is N(μ=4378, σ=565). The distribution for women ages 25 - 29 is N(μ=5212, σ=849). Note, these distributions list the triathlon times in seconds. Use this information to compute each of the following. Report your answer to 2 decimal places.
a) The cutoff time for the fastest 5% of athletes in the men's group, i.e. those who took the shortest 5% of time to finish.
b) The cutoff time for the slowest 10% of athletes in the women's group.
Using the normal distribution, it is found that:
a) The cutoff time for the fastest 5% of athletes in the men's group is of 3448.58.
b) The cutoff time for the slowest 10% of athletes in the women's group is of 6298.72.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.Item a:
For men, we have that [tex]\mu = 4378, \sigma = 565[/tex].
The cutoff for the fastest 5% of the athletes is the 5th percentile, which is X when Z has a p-value of 0.05, that is, X when Z = -1.645.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-1.645 = \frac{X - 4378}{565}[/tex]
[tex]X - 4378 = -1.645(565)[/tex]
[tex]X = 3448.58[/tex]
The cutoff time for the fastest 5% of athletes in the men's group is of 3448.58.
Item b:
For women, we have that [tex]\mu = 5212, \sigma = 849[/tex].
The cutoff is the 90th percentile, which is X when Z = 1.28, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.28 = \frac{X - 5212}{849}[/tex]
[tex]X - 5212 = 1.28(849)[/tex]
[tex]X = 6298.72[/tex]
The cutoff time for the slowest 10% of athletes in the women's group is of 6298.72.

Simplify the expression:
2+1d+3a=4
Answer:
d=2-3a
Step-by-step explanation:
Solve for d by simplifying both sides of the equation, then isolating the variable.
3d+3a=4
Subtract 3 from each side of the equal sign:
d+3a=1
Subtract 3a-1:
d=2-3a
Hence d=2-3a is your final answer
Answer:
d = 2 - 3a
a = -d+2/3

In a class there are 21 boys and girls make up 0.4 find the total students in class
Answer:
35
Step-by-step explanation:
let x be the number of students in the class
then number of girls = 0.4x , so
x = 21 + 0.4x ( subtract 0.4x from both sides )
0.6x = 21 ( divide both sides by 0.6 )
x = 35
the total number of students is 35

An adult movie ticket costs $10 and a student movie ticket costs $6. A popcorn combo costs $8. Find the cost difference between 6 adult
tickets and 6 popcorn combos and 6 student tickets and 6 popcorn combos
Answer: $24
Step-by-step explanation:
Since the popcorn combos are the same amount, we are essentially calculating the difference between 6 adult tickets and 6 student tickets.
6 adult tickets are $10*6 = $60, while 6 student tickets are $6*6 = $36.
60-36= $24
Every square is a trapezoid. Is this true or false?
Answer: This is true. Every square has 2 pairs of parallel sides and the conditions for a shape to be a trapezoid is if it has at least 1 pair of paralell sides. Since a square satisfies these conditions, it is a trapezoid.
f(n) = 10*(10x + 10)
f(10) = ?
Answer:
f(10) = 1100
given:
f(n) = 10(10x + 10)
solve:
f(10) = 10(10(10)+10)
f(10) = 10(100+10)
f(10) = 10(110)
f(10) = 1100
Answer:
1100
Step-by-step explanation:
f(n) = 10*(10x + 10)
f(n) = 100x + 100
f(10) = 100(10) + 100
f(10) = 1100

Which of the following is an example of a rational number that is an integer
and a whole number?
Answer:
-2/5 , -7/13 , 7/11 , 5/84
1. The answer would be "-15" since integers are composed of whole numbers and negatives.
2. The statement "Every real number is a rational number." is false, since real numbers are composed of both rational and irrational numbers.
3. The number "8.52624 . . ." because this is the only non-terminating number, which makes it the only irrational number on the list.
4. "Irrational numbers cannot be classified as rational numbers." is the only correct statement. No irrational numbers can be rational numbers, and the opposite is also true.
5. Only the statement "Every irrational number is a real number." is true.

What is ∑n=124(5n−7) equal to?
Enter your answer in the box.
The sum of the sequence is 300
Sum of sequenceGiven the sum of sequence;
∑n=(5n−7)
We are to get the sum of the sequence from n = 1 to n = 24
The formula for calculating the sum of the sequence is expressed as:
Sn = n/2(a+l)
Given the following parameters
a = 1
l = 24
n = 24
S24 = 24/2(1 + 24)
S24 = 12(25)
S24 = 300

Answer:
(d) -11
Step-by-step explanation:
Each of the functions is evaluated in the usual way: put the number where the variable is in the expression and simplify.
h(-1) = -2(-1)² -3(-1) +1 = -2 +3 +1 = 2
f(2) = (2(2) +7)/(2 -3) = 11/-1 = -11
Then f(h(-1)) is ...
f(h(-1)) = f(2) = -11
