Answer:
f(x) = x*3/4 + 42.5
Step-by-step explanation:
The original difference between the pair is 70 - 30 = 40
The new difference between the pair is 95 - 65 = 30
Since the differences are not the same, Mrs Bailey must first perform a (slope) multiplication by a factor of 30/40 or 3/4
Then 30 * 3/4 = 22.5
Then she can shift the scores up by 65 - 22.5 = 42.5 in order to get the range from 65 to 95
Therefore, f(x) = x*3/4 + 42.5. We can test that
f(30) = 30*3/4 + 42.5 = 65
f(70) = 70*3/4 + 42.5 = 95
Step-by-step explanation:
Well, this is a function. In order to solve this, you need a v value. Once you get a v value, you can plug into into 6+v^2 and wala- you get your answer.
Example, lets say
v is 3
then
F(3) = 6 + 3^2
f(3) = 6 + 9
f(3) =15
Hope this helped
Answer:
89.84375
Step-by-step explanation:
Given that on a finance exam, 15 accounting majors had an average grade of 90. On the same exam, 7 marketing majors averaged 85, and 10 finance majors averaged 93.
To find weighted mean.
Here weights can be considered as number of majors in each subject
Weighted total = 1350+595+930 = 2875
Weighted mean = weighted total/total students
Answer:
f(x) is the total cost and x is the number of peaches.
Step-by-step explanation:
We know that each peach costs $0.75. This means the expression 0.75x represents the total cost of peaches; this makes x represent the number of peaches.
We also know that $2.25 is the cost of juice. Adding it to the cost of peaches gives us the total cost; this means f(x) represents the total cost.
