First how much does the nickels worth?
It worths 5 cents Which is .5 in decimal and now you got to divide
So divide 7.45 over .5 how much is that ?
7.45/.5=14.9
There are approximately 15 nickels.
Probability that no samples are mutated is 0.83, probability that at most one sample is mutated is 0.9812 and probability that more than half the samples are mutated is 0.
Given percentage of rejuvenated mitochondria defective is 1%, and sample size is 18.
Binomial distribution is the probability of exactly x successes on n repeated trials and X can have two outcomes.
P(X=x)=
percentage of defective rejuvendated mitochondria=1%
p=0.01
Sample size=18
n=18
a) No samples are mutated
This means P(X=0)=
=0.83
b) At most one sample is mutated.
P(X<=1)=P(X=0)+P(X=1)
so,
P(X=0)=
=0.83
P(X=1)=
=
=0.1512
P(X<=1)=0.83+0.1512
=0.9812
c) More than half the samples are mutated.
P(X>9)=P(X=10)+P(X=11)+P(X=12)+P(X=13)+P(X=14)+P(X=15)+P(X=16)+P(X=17)+P(X=18)
Using two decimals digits precision all will be 0.
Hence Probability that no samples are mutated is 0.83, probability that at most one sample is mutated is 0.9812 and probability that more than half the samples are mutated is 0.

Hi,
Answer: 0.24 per liter
<u>My work:</u> This problem is easily achievable all you have to do is take your caculator and take price Melvin would pay with his loyalty card 1.679 and subtract it with 1.439. (1.679 - 1.439) When you do this you easily achieve your answer; Melvin pays 0.24 less per liter using his loyalty card.
I Hope it helped!
B. I think I’m really not sure that’s confusing as hell and I’ve passed that
1. this is a series of squares Formula is an = n^2
2. Arithmetic series with common difference d = -2.
an = a1 + (n-1)d = 3 -2(n-1)
Cant see the rule for Number 3
