Answer:
x=3
y=12
Table:
x=3,6,9,12
y=12,24,36,48
Step-by-step explanation:
To find the amount of sugar needed for 4/9 of a batch, just multiply the standard batch (2 3/7 cups) by 4/9, for a result of 1 5/63 cups of sugar.
To find the amount of flour needed for a triple batch, multiply the base amount of flour, or 4 1/5, by three, to get 12 3/5 cups of flour.
Answer:
.88
Step-by-step explanation:
The standard deviation is the square root of the variance.
I think it is B -2 < x < 2
A^2 + B^2 = C^2.
so 49 + 576 = C^2
625 = C^2
Now find the square root of 625.
25 = C (in your case r)
