Answer:
8 shirts, $60
Step-by-step explanation:
Company A: 20+5x=y
Company B: 7.50x=y
Since y represents the amount of money and x represents the number of shirts, you set them equal to each other and solve for x to find the number of shirts where they will have the same amount of money.
20+5x=7.50x
20=2.50x
x=8 shirts
Now that we know they will have the same amount of money at 8 shirts, you just plug in 8 for x on one of the starting equations. You can plug 8 in to both to double check that it gives the same value for both.
20+5(8)= 60
7.50(8)= 60
We have verified that with 8 shirts, they will both be making 60 dollars.
Bachelor's degree salary = $53000
Master's degree salary = $66000
Step-by-step explanation:
Given that :
Let Salary of bachelor's degree holder = x
Salary of Master's degree holder = 2x - 40000
Master's salary + bachelor's salary = $119,000
Hence,
Master's salary + bachelor's salary = 119,000
2x - 40000 + x = 119,000
3x = 119000 + 40000
3x = 159000
x = 159000 / 3
x = $53,000
Bachelor's degree salary = $53,000
Master's degree salary ; 2x - 40000 ; 2(53000) - 40000 = $106,000 - $40,000 = $66000
There are no 3s in 1/8... 1/8= 0.125
To find this answer, first subtract 1,500 from the amount your class raises (16, 600) so you are just left with the 'leftover' money for students to board.
16600-1500= 15100.
Then, divide 15100 into 367 to find out how many can go.
15100/367= 41.1444. Round down to 41.
41 students can attend, and there will be a bit of leftover money. (if you want to figure out how much is left over, multiply 41 by 367, and then subtract 15100 by the product)
Answer:
a) 4
Step-by-step explanation:
Take the equation:
x + 1483 = 2113.833
Solve for x:
x = 2113.833 - 1483
x = 630.833
To find df, take the equation:
Where x = 630.833
Solve for y:
y ≈ 3
Take number of treatments = k
Degrees of freedom, df, of numberof treatments = k - 1
Therefore,
Where df = 3, we have:
k - 1 = 3
Solve for k:
k = 3 + 1
k = 4
The number of treatment groups is 4
