Answer: 61.51%
Step-by-step explanation:
To find : percentage for a 20 year old man with a cholesterol level less than 190.
20 lies between 18 and 24.
For this , Cholesterol levels are normally distributed with a mean([tex]\mu[/tex]) of 178 and a standard deviation([tex]\sigma[/tex]) of 41.
let X = cholesterol level in 20 year old man.
Required probability = [tex]P(X< 190)=P(\dfrac{X-\mu}{\sigma}<\dfrac{190-178}{41})[/tex]
[tex]=P(z<0.2926)\ \ \ \ [z=\dfrac{X-\mu}{\sigma}]\\= 0.6151 [\text{By p-value table}][/tex]
hence, the percentage for a 20 year old man with a cholesterol level less than 190 = 61.51%

Answer:
[tex]-5*2[/tex] is larger.
Step-by-step explanation:
[tex]-5*2=-10[/tex]
[tex]-14+1=-13[/tex]
[tex]-10>-13[/tex]
-10 is greater because both numbers are negative, so -10 is the higher number.
Answer:
5 x 2 is the larger than -14 + 1.
Step-by-step explanation: -5 x 2 = -10, and -14 + 1 = -13. Plz tell me if you got it right.

hope this helps
Answer:
81 is the perfect square of the first option
Step-by-step explanation:
It is asking for the perfect square so the third option will be eliminated because that is cubed.
The fourth option will also be eliminated because it is multiplication.
The second option will be eliminated because it has addition.
81 is the perfect square of the first option

The gas tank on a car holds 13.4 gallons. If the car goes 335 miles on a single tank, how many miles per gallon does the car get? Provide an explanation of what the final answer means, in terms of the given problem. Show all work.
chile..
Answer:
The car gets 25 miles per gallon.
It means that for each gallon of gas the car uses, it will travel a distance of 25 miles.
Step-by-step explanation:
"Miles per gallon" is calculated by dividing the number of miles by the number of gallons.
mpg = (335 miles)/(13.4 gallons) = 25 miles per gallon
Answer:
The car gets 25 miles per gallon.
It means that for each gallon of gas the car uses, it will travel a distance of 25 miles.
Answer:
25
Step-by-step explanation:
You need to divide 335 miles by 13.4 to find the miles per gallon. 335 miles divided by 13.4 gallons is 25. So for every 25 miles you use 1 gallon.

Step-by-step explanation:
Add 82+54.
Subtract 136 from 180. Giving you your answer.
Always subtract from 180 since a triangle is always 180.
Can you mark me brainliest? And 5 star?
Answer:
x= 44
Step-by-step explanation:
180 = 82 + 54 + x
180 = 136 + x
180 - 136 = 136 -136 + x

Answer:
Step-by-step explanation:
a
The square root of 20 = 4.47 so a for sure.
But the root of 20 is also -4.48 so that means that 2 and 3 are added to the list
Now what to do about - 8
(- 8)^2 = 64
The square root of 64 = +/- 8
It's kind of slippery but it depends on how you see the problem. It is a bit ambiguous.
I would eliminate - 8 but your instructor may not. Argue that it should not be included, but don't take the argument on forever. Let it go.
a for sure.

change them to improper fractions
2 1/2= 5/2 1 2/3=5/3
divide y from 5/3:
[tex]\frac{5}{2} y=\frac{5}{3}[/tex]
mutiply each side by 2/5
y=10/15=2/3
here is your answer. change them to improper fractions
2 1/2= 5/2 1 2/3=5/3
divide y from 5/3:
mutiply each side by 2/5
y=10/15=2/3

Step-by-step explanation:
Hamish and Harry work as plumbers. Harry earns a dollar more than the amount Hamish earns per hour. The amount Harry earns per hour is less than the amount Hamish earns per hour. How much does each of them earn per hour? A. Hamish earns $18 per hour, and Harry earns $23 per hour. B. Hamish earns $19 per hour, and Harry earns $24 per hour. C. Hamish earns $21 per hour, and Harry earns $25 per hour. D. Hamish earns $20 per hour, and Harry earns $26 per hour.
Answer:
D. Hamish earns $20 per hour, and Harry earns $26 per hour.
Step-by-step explanation:
Hamish and Harry work as plumbers. Harry earns a dollar more than 5/4 the amount Hamish earns per hour. The amount Harry earns per hour is $2 less than 7/5 the amount Hamish earns per hour. How much does each of them earn per hour?
Hamish earnings per hour = x
Harry earnings = 1 + 5/4x
The amount Harry earns per hour is $2 less than 7/5 the amount Hamish earns per hour
Harry also earns = 7/5x - 2
Equate both Harry's earnings
1 + 5/4x = 7/5x - 2
Collect like terms
1 + 2 = 7/5x - 5/4x
3 = 28x-25x/20
3 = 3/20x
Divide both sides by 3/20
x = 3 ÷ 3/20
= 3 × 20/3
x = 20
Hamish earnings per hour = x
= $20
Substitute Harry's earnings into 7/5x - 2
= 7/5 × 20 - 2
= 28 - 2
= 26
Harry's earnings = $26
D. Hamish earns $20 per hour, and Harry earns $26 per hour.

Donna receives a $100 gift card to MovieStop. Her Blu-ray player is able to play both Blu-rays and DVDS, so she would like to get a combination of both. Each Blu-ray cost $25.99 and DVDs cost $15.99 each. Write an equation modeling the number of Blu-rays, b, and DVDs, d, that Donna can purchase with her gift card.
Answer:
100=25.99b+15.99dStep-by-step explanation:
step one:
let the number of Blu-rays be b and
DVDS be d,
step two:
given that Blu-rays cost $25.99each and
DVDS cost $15.99 each,
we can model the cost of the Blu-rays and DVDS, as
100=25.99b+15.99d
hence the expression for the number of Blu-rays and DVDS, is given as
100=25.99b+15.99d

) Suppose you are installing a wood floor in a square room. The cost to install the floor is $9 per square foot. The area of the room is given by the function A(x) = x 2 and the cost per square foot is given by the function C(A) = 9A. Which function can be used to find the total cost to install the wood floor? A) A(C(x)) B) C(A(x)) C) x(A(C)) D) x(C(A))
Answer:
The correct option is;
B) C(A(x))
Step-by-step explanation:
The given information are;
The cost to install the floor per square foot = $9
The area of the room is given by the function A(x) = x²
The function for the cost per square foot = C(A) = 9·A
We note that the total cost to install the wood floor = (The cost to install the floor per square foot) × (The area of the room)
∴ The total cost to install the wood floor = $9 × x²
Given that A(x) = x², we have;
The total cost to install the wood floor = $9 × A(x)
Also, given that C(A) = 9·A, we have;
C(A(x)) = 9·A(x)
Therefore;
The total cost to install the wood floor in dollar amount can be given by the function, C(A(x)) = 9·A(x)

Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
d) x = 4/3
Step-by-step explanation:
Given equation,
→ -x + (3/7) = 2x - (25/7)
Now the value of x will be,
→ -x + (3/7) = 2x - (25/7)
→ -x - 2x = -(25/7) - (3/7)
→ -3x = -28/7
→ -3x = -4
→ x = -4/-3
→ [ x = 4/3 ]
Hence, the value of x is 4/3.
