75/3 = 25
so you would take the miles and divide it by the time since you know the time, and you would get the miles per mile.
In standard form it would be 20 + 2/x
U can find the unit rate by looking where is the point so in that pic the unit rate I see is: 3/5
The answer choice which would be the MOST difficult to adjust if you were looking to reduce your expenses is:
- Loan payment on a new car
<h3 /><h3>What is Budgeting?</h3>
This refers to the reduction of costs by making a plan to which a person would base his financial decisions.
With this in mind, we can see that if a person wants to reduce expenses, then making adjustments on a loan payment for a car would be the most difficult because he has to make periodic payments for the car.

Answer:
Step-by-step explanation:
Given that,
- p ( probability that the child has disease) = 25% = 0.25
- n = number of children = 3
The probability mass function of binomial distribution is,
- (P = X) = (nCx) X (p)^x X (1 - p)^n-x ; x = 0, 1, 2 ,3
- = 3Cx X (0.25)^x X (1 - 0.25)^3-x ; ( n = 3, p = 0.25
a) P ( two will have disease)
p ( X = 2) = 3C2 X (0.250^2 X (1 - 0.25) ^3-2
= 0.1406
b) P ( none will have disease)
p (X = 0) = 3C0 X (0.25)^0 X (1 - 0.25)^3-0
= 0.4219
c) P (neither having the disease nor being a carrier) = 25% = 0.25
The probability that at least one will neither having the disease nor being a carrier ;
P(X> or equals to) = 1 - P(X < 1)
= 1 - P( X = 0)
= 1 - 3C0 X (0.25)^0 X (1 - 0.25)^3-0
= 0.5781
d) p( the first child with the disease will the be 3rd child)
P(X = x) = (1-p)^x-1 X p
p( X= x) = ( 1 - 0.25 )^x -1 X 0.25
for third child = P(X = 3) = (1 - 0.25)^3-1 X (0.25)
= 0.1406
