Answer:



Step-by-step explanation:
Given
Let
A = Event of being a universal donor.
So:


Solving (a): Mean and Standard deviation.
The mean is:



The standard deviation is:




Solving (b): P(x = 3)
The event is a binomial event an dthe probability is calculated as:

So, we have:




Distance from focus to vertex=distance from vertex to directix
from (6,2) to y=1, the distance is 1
the focus is 1/2 higher than the vertex
vertex=(6,1.5)
for
(x-h)^2=4p(y-k)
vertex=(h,k)
p=distance from vertex to directix
vertex=(6,1.5)
ditance=0.5
(x-6)^2=4(0.5)(y-1.5)
(x-6)^2=2(y-1.5) is the equation
or
y=0.5x^2-6x+19.5 or
y=0.5(x-6)^2+1.5
$6.75 Because 3/8 x $18.00 is $6.75
Answer: 58 months
Step-by-step explanation:
Let x represent the number of month to pay off the loan
$25,000 - $15,000 + $25x = 200x
Now it is simple algebra
10,000+25x= 200x Subtract 25 x from both sides
10,000 = 175x
x=57.14 month so Really 58 months till they pay it off
