The numerical values of the mean and standard deviation are 4 and 1.55, respectively
<h3>The
numerical value of the
probability that x = 6. </h3>
The given parameters are:
n = 10
π = 0.4
The probability is then calculated as:

So, we have:

Apply the combination formula

So, we have:

Evaluate
P(6) = 0.1115
Hence, the numerical value of the probability that x = 6 is 0.1115
<h3>The numerical values of the mean and standard deviation </h3>
The mean value is:

This gives


The standard deviation value is:

This gives


Hence, the numerical values of the mean and standard deviation are 4 and 1.55, respectively

First you need to find the middle number, wich is 75. Since there is no $75, I would go with $80.
-19/40.
This can be found using the slope formula.
Answer:
25 months
Step-by-step explanation:
Plan A : $70 per month
Plan B : $50 per month + $500 as a one time cost.
So for A $70 a month would take 8 months to be at least $500
And for B it in those 8 months it would cost you $900
But we have to keep going up until they are equal
25*70 = 1750
(25*50) = 1250+500=1750
So yes 25 months is correct
