5 times amount of people has to be bigger than 2112
5(133+v)≥2112
distribute
665+5v≥2112
minus 665 from both sides
5v≥1447
divide both sides by 5
v≥289.4
yo can't have 0.4 volunterer
v≥290
has to have at least 290 volunteers
We need (x-h)^2 + (y-k)^2 = r^2
h = 4, k = 0 and r = 2/3
Take it from here.
115:55 bc if you divide them both you fat the same answer which is 2
Answer:
the amount after 3 weeks is $37.33
Step-by-step explanation:
Given that
His balance is -$48.82 i.e. overdraft
Now in order to get the positive balance, he plans to deposit the money of $28.55 per week
We need to find out the amount after 3 weeks

= -$48.32 + $28.55 + $28.55 + $28.55
= $37.33
hence, the amount after 3 weeks is $37.33
Answer:
1006
Step-by-step explanation:
Take proportion, p = 62%
n = (Z² * pq) / M.E²
Margin error = 0.03
p = 62% = 0.62
q = 1 - p = 1 - 0.62 = 0.38
Zcritical at 95% = 1.96
n = (1.96² * (0.62*0.38)) / 0.03²
n = 0.90508096 / 0.0009
n = 1005.6455
n = 1006
Sample size = 1006
