Varies directly means
if y varies directly as x that means
y=kx where k is a constant
so
y=kx
y=2 and 2/3 when y=1/4 then find k
convert 2 and 2/3 to imporoper fraction for ease
2 and 2/3=6/3+2/3=8/3
8/3=k(1/4)
multiply both sides by 4/1 to clear fraction
32/3=k
so now we have
y=(32/3)x
when x=1 and 1/8
find y
convert 1 and 1/8 to imporopor=9/8
y=(32/3)(9/8)
y=(288)/(24)
y=12
Answer is in fractions 79/24 and in decimals it is 5.642857143
Answer:f(x) = x + 21
f(4) = 4 + 21
= 25
Step-by-step explanation:
Answer:
e)$141,750
Step-by-step explanation:
Let be
AG = Members with advanced degrees
BG = Members with a bachelor's degree
DG = Members with a no degree
In a sample of 50 members it is expected a total of members for every group as follows
For AG = 30 * 0.5 = 15
For BG = 50 * 0.5 = 25
For DG = 20 * 0.5 = 10
The expected donation for every group would be the number of members by the 5% of their incomes
For AG = 15 * 0.05 * $75,000 = $56,250
B For G = 25 * 0.05 * $54,000 = $67,500
For DG = 20 * 0.05 * $36,000 = $18,000
Total donation is the sum = $141,750
