Step-by-step explanation:
Sam and Taylor own and operate a car wash service. Sam cleans the interior of each car and Taylor cleans the exterior. The time it takes Sam to finish the interior has a mean of 20 minutes with a standard deviation of 6.4 minutes. The time it takes Taylor to finish the exterior has a mean of 18 minutes with a standard deviation of 4.8 minutes. Both of their finishing times are approximately normally distributed.
Suppose we select a car at random, and define the random variable D as the difference between their finishing times. We can assume that their times are independent.
Find the probability that they finish within 10minutes of each other.
You may round your answer to two decimal places.
P\left(|D|<10\right)\approxP(∣D∣<10)≈P

A road is made in such a way that the center of the road is higher off the ground than the sides of the road, in order to allow rainwater to drain. A cross-section of the road can be represented on a graph using the function f(x) = (x – 16)(x + 16), where x represents the distance from the center of the road, in feet. Rounded to the nearest tenth, what is the maximum height of the road, in feet?

Answer:
x = 8
Step-by-step explanation:
2x+5=21
Step 1: Subtract 5 from both sides.
2x+5−5=21−5
2x=16
Step 2: Divide both sides by 2.
2x /2 = 16 /2
x = 8
Answer:
x = 8
Step-by-step explanation:
2x + 5 = 21
2x = 21 - 5
2x = 16
x = 16/2
x = 8

At every company meeting, the president speaks for 28 minutes and then takes questions from her employees. Let q represent the number of minutes she spends answering questions and t represent the total number of minutes the meeting lasts.
Answer:
t = 20 + q in minutes
Step-by-step explanation:
Company meeting = president speech + questions + answers
President speech = 20 minutes
Questions and answers = q minutes
Total time spent = t minutes
Total time spent = President speech + Total time spent
t = 20 + q
The equation that represents the relationship between q and t is
t = 20 + q in minutes
Which equation is modeled below?

HELP DUE SOON!!!Elise says, "If you subtract 14 from my number and multiply the difference by - 4, the result is
- 100." What is Elise's number?
Elise's number is
Answer:
39
Step-by-step explanation:
If you subtract 14 from my number and multiply the difference by -4, you should get -100.
You need to setup the equation that is being given to you.
Subtract 14 from my number.
x - 14
Multiply the difference by -4
(x-14) * -4
You should get -100.
(x-14) * -4 = -100
Solve for x
(Elise's number is X, the missing number).
[tex]-4(x-14) = -100\\-4x+56 = -100\\-4x=-156\\x=39[/tex]
Elise's number is 39.

Fred's Fruit Stand has 252 pounds of fruit and sells 2 7/8 pounds per hour. Gary's grocery Store has 285 pounds of fruit and sells 3 1/3 pounds per hour. How many hours until they have the same amount of fruit left?
Answer:
72.1 hours
Step-by-step explanation:
Let the number of hours be represented as: x
Fred's Fruit Stand has 252 pounds of fruit and sells 2 7/8 pounds per hour.
Convert 2 7/8 pounds to decimal = 2.875pounds
Hence:
252 - 2.875x
Gary's grocery Store has 285 pounds of fruit and sells 3 1/3 pounds per hour.
Convert 3 1/3 pounds to decimal = 3.333 pounds
Hence:
285 - 3.333x
How many hours until they have the same amount of fruit left?
This calculated by equating both equation together
252 - 2.875x = 285 - 3.333x
Collect like terms
-2.875x + 3.333x = 285 - 252
0.458x = 33
x = 33 / 0.458
x = 72.052401747 hours
x ≈ 72.1 hours
They would have the same amount of fruit left after 72.1 hours

Write an expression that is equivalent to 3k - 18
Answer:
3(k-6)
Step-by-step explanation:
I did it on i-Ready and got it right!
A common factor of 3k and 18 that is greater than 1 is 3.
An expression that shows 3k minus 18 is 3(k)-3(6).
An expression that is equivalent to 3k - 18 can be written as follows:
3(k - 6)
Given is an expression 3k-18 we need to an expression that is equivalent to it,
Let's break it down to understand why this expression is equivalent to 3k - 18:
Distributive Property: The expression 3(k - 6) can be expanded using the distributive property, which states that for any real numbers a, b, and c: a(b + c) = ab + ac.
In this case, a is 3, and b is k while c is -6. So we can apply the distributive property as follows: 3(k - 6) = 3k + 3(-6).
Simplification: The term 3(-6) can be simplified to -18, so the expression becomes 3k - 18.
Therefore, the expression 3(k - 6) is equivalent to 3k - 18 because both expressions yield the same result when evaluated for any value of k.

Kristopher has a coupon for $10 off any item at his favorite electronics shop. If he plans to use the coupon to purchase and item that costs $80, by what percentage will the price be decreased before tax?
Answer:
12.5%
Step-by-step explanation:
Kristopher has a coupon for $10 off any item at his favorite electronics shop. If he plans to use the coupon to purchase and item that costs $80, by what percentage will the price be decreased before tax?
The formula for Percentage Decrease =
Decrease in price/ Initial price × 100
Decrease in price = $10
Initial price = $80
Hence:
$10/$80 × 100
= 12.5%
Hence, the percentage the price will be decreased by before tax is 12.5%

the area of a small square is 25 square units what is the exact length in units of a single of a large square
Answer:
5
Step-by-step explanation:
The area of any quadrilateral can be determined by multiplying the length of its base by its height. Since we know the shape here is square, we know that all sides are of equal length. From this we can work backwards by taking the square root of the area to find the length of one side.
