I'm going to reword your question so it's easier to answer. I'm also going to pretend no one has 3 or more accounts because it's irrelevant.
22% have no accounts (220/1000)
What is the probability that 4 or more of the 10 participants has no account?
(220/1000)*(219/999)*(218/998)*(217/997)*(10 choose 4)

Pam and her brother both open savings accounts. each begin with a
balance of $0. For every $2 is that Pam saves in her account her brother
saves $5 in his account
P:bro=2:5
when P=40 what is bro?
2/5=40/b
times 5b both sides
2b=200
divide 2
b=100
bro has $100

The volume of a sphere is:
V=(4πr^3)/3, and you are told that r=5in so
V=(4π125)/3
V=500π/3 in^3
V≈523.60 in^3
Answer:
1) 75 copies were sold
2)expected wage=720
Step-by-step explanation:
in this equation, y represents wages and x represents number of copies sold
lets take the trendline, y=6x+120
since the amount earnt is $570, we can take this to be our y variable
570=6x+120
450=6x
x=75
1) 75 copies r sold
2) this time we substitue the 100 for x
y=6(100)+120
y=600+120
y=720
2) expected wage=720
