A reporter wants to interview an employee who works fewer than 30 hours per week. Is the reporter more likely to find such a person at Company A or at Company B?
Answer:
Company B
Step-by-step explanation:
Company B has staff who works for less than 30 hours per week since it is a software company which freelances various technicians. They are free to work on the time of availability and there is no restriction of work to be done. They are paid on the basis of tasks they complete and they work remotely. The interviewer should select an employee from Company B because they work less than 30 hours per week.
Julio runs 4 miles each time that he goes running. If he goes running 7 times a week, how many miles does he run total in one week?
Answer:
He runs 28 Miles every week!
Step-by-step explanation:
(The week is 7 days long)
1st DAY = 4M
2nd DAY = 4M
3rd DAY = 4M
4th DAY = 4M
5th DAY = 4M
6th DAY = 4M
7th DAY = 4M
(The M next to the 4 means miles you don't have to include it in your answer on your homework!)
4 + 4 + 4 + 4 + 4 + 4 + 4 = 28
OR
4 x 7 = 28

A substance weighing 961 ounces decays at a rate of 3.2% PER HOUR. What is the weight of the substance after ONE DAY?
Answer:
222.952 ounces
Step-by-step explanation:
3.2% of 961 = 30.752
Hours in one day = 24 Hours
30.752 x 24 = 738.048
961 - 738.048 = 222.952
After 2.5 years your investment account has earned $450 in interest. If the interest rate is 7.5% what was the principle on your account?
Answer: $2400
Step-by-step explanation:
Given
Interest earned is $450
The rate of interest is R=7.5%
Time period T=2.5 years
Simple Interest is given by
[tex]S.I.=\dfrac{P\times R\timesT}{100}\quad [\text{P=Principal}][/tex]
Substitute values
[tex]450=\dfrac{P\times 7.5\times2.5}{100}\\\\P=\dfrac{450\times 100}{7.5\times 2.5}=\$2400[/tex]

A gym offers two different membership options. In the first option, new members pay a one-time fee of $50 and a monthly fee of $30. In the second option, members pay a one-time fee of $100 and a monthly fee of $20.
Suppose c is the total membership cost for m months. The two equations that model the two membership options are c = 30m + 50 and c = 20m + 100.
Part A
1. To find out when the cost will be equal, you will need to solve for m using substitution. Substitute the expression for the cost from the first equation into the cost, c, in the second equation.
2. Solve the equation in number 1 for m
3. Would you get the same solution if you substituted the expression for cost in the second option for c in the first equation? Why?
9514 1404 393
Answer:
30m +50 = 20m +100m = 5yes. symmetric property of equality.Step-by-step explanation:
1. The expression for c in the first equation is (30m+50). Substituting that for c in the equation ...
c = 20m +100
gives you ...
30m +50 = 20m +100
__
2. Adding -50-20m to both sides gives ...
10m = 50
m = 5 . . . . . . . divide by 10
__
3. Doing the substitution in reverse, you would substitute (20m+100) for c in the equation ...
c = 30m +50
to get ...
20m +100 = 30m +50
This is the equation of part 1 with the expressions swapped to the other side of the equal sign. The symmetric property of equality tells you that changing sides of the equal sign does not change the value of the variable(s).
You get the same solution.

Step-by-step explanation:
if they won 12 games which is 40% of their total games played 100% is the number of games played .form an equation...
if 12=40
x=100 cross multiply 12 and 100 then divide by 40 to get x
12×100=1200÷40=30.

There are 8 oranges, 5 apples, and 6 bananas In the fruit basket.
-Bob says the ratios of apples to bananas is 5:6
-Rob says the ratios of bananas to apples is 6:5
-Thob says that the ratios of apples and bananas to all the fruit is 11:19
Who is correct? I REALLY need an explanation.
Step-by-step explanation:
all of them are correct
there are 5 apples and 6 bananas
there are 6 bananas and 5 apples
5 apples plus 6 bananas=11
8 oranges+5 apples+6 bananas=19
so the ratio is 11:19
Answer:
they are all correct
Step-by-step explanation:
a ratio is a comparison saying that for every group of numbers that there will be another group of numbers for example
the ratio of apples to bananas is
number of apples->5:6<- number of bananas
so of the ratio stays the same then for every 5 apples added to the basket then 6 bananas will also be added(works other way to)
The _____ _____, denoted modifyingabove p with caret, is given by the formula modifyingabove p with caretequals_____, where x is the number of individuals with a specified characteristic in a sample of n individuals. the ▼ ▼ deviation mean proportion error variance , denoted modifyingabove p with caret, is given by the formula modifyingabove p with caretequals ▼ xn startfraction n over x endfraction startfraction x over n endfraction , where x is the number of individuals with a specified characteristic in a sample of n individuals.
Answer:
Sample proportion ; phat
x / n
Step-by-step explanation:
The sample proportion may be explained as a proportional representation of part of the population or larger sample which have a certain character or exhibit a particular trait.
The sample proportion is expressed Mathematically as ;
phat = x / n
x = number of subjects with a specified characteristic ;
n = total sample size
For instance ;
The proportion of black balls in a sample of 100 balls is 15 ; the sample proportion of bla k balls will be :
phat = x / n = 15 / 100 = 0.15
A can has a radius of 3 inches and a height of 8 inches. If the height is doubled, how would it affect the original volume of the can?
Answer:
In the formula, the radius is being squared. That means that doubling the radius of the cylinder will quadruple the volume. ... If we put all of that information together (doubling the radius quadruples the volume, while doubling the height doubles the volume), we find that the volume will be 8 times as large

The school you are attending is selling tickets to the fall festival. On the first day, the school sold 14 senior citizen tickets and 1 child ticket for a total of $66.50. On the second day, the school sold 2 senior citizen tickets and 2 child ticket for a total of $16.00. What is the price of one senior citizen ticket?
Answer:
Price of each senior citizen ticket is $12 and one child ticket is $3
Step-by-step explanation:
The price of one senior citizen ticket is $ 4.50.
Let x = price of one senior citizen ticket and y = price of one child ticket.
Now, since On the first day, the school sold 14 senior citizen tickets and 1 child ticket for a total of $66.50. WE have that
14x + y = 66.50 (1)
Also, on the second day, the school sold 2 senior citizen tickets and 2 child tickets for a total of $16.00. We have that
2x + 2y = 16.00 (2)
From (1), y = 66.50 - 14x
Substituting y into (2), we have
2x + 2y = 16.00
2x + 2(66.50 - 14x) = 16.00
2x + 2(66.50 - 14x) = 16.00
2x + 133 - 28x = 16
2x - 28x = 16 - 133
-26x = -117
x = -117/-26
x = 4.5
So, the price of one senior citizen ticket is $ 4.50.
