Answer:
"Brand A costs approximately $0.21 per ounce, and Brand B costs approximately $0.18 per ounce."
In order to find the rounded cost per one item (in this case, per one ounce) Susan needs to divide the total price between the number of units and after that, round the result obtained up to the nearest cent.
Therefore:
Brand A
2.55$/12 ounces= 0.2125 $/ounce
As the third decimal digit, 2, is closer to 0 than to 9, then we maintain the second decimal digit as 1.
The price per unit of brand A after rounding it up is 0.21 $ per ounce
Brand B
1.45$/8 ounces= 0.1812
As the third decimal digit, 1, is closer to 0 than to 9, then we maintain the second decimal digit as 8.
The price per unit of brand B after rounding it up is 0.18 $ per ounce
I got 3x^2 + 12x + 4. I recommend you verify my answer, so you have to combine like terms in the first expression then add all the expressions.
Answer:
36%
Step-by-step explanation:
9/25
multiply each by 4 to get 36/100

Answer: The mean increases by 3
-----------------------------------------------------------
-----------------------------------------------------------
The original data set is
{50, 76, 78, 79, 79, 80, 81, 82, 82, 83}
The outlier is 50 because it is not near the group of values from 76 to 83 which is where the main cluster is.
The original mean is M = (50+76+78+79+79+80+81+82+82+83)/10 = 77
If we take out the outlier 50, the new mean is N = (76+78+79+79+80+81+82+82+83)/9 = 80
So in summary so far
old mean = M = 77
new mean = N = 80
The difference in values is N-M = 80-77 = 3
So that's why the mean increases by 3
Answer:
For each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $110,000.
Step-by-step explanation:
The sales price is not predicted to increase by $1.1; it is predicted to increase by $110,000 because S is measured in hundred-thousands of dollars. The sales price will not decrease by $110,000; it is predicted to increase by $110,000.
