Answer:
The unit rate is -0.5 store per year
Step-by-step explanation:
Let
x -----> the number of years since 1996
y ----> the number of video rental stores
we know that
The year 1996 represent x=0
so
2016 represent ----> x=2016-1996=10 years
we have the points
(0,9) and (10,4)
The unit rate is equal to the slope of the linear equation
<em>Find the slope m</em>
----> is negative because is a decreasing function
therefore
The unit rate is -0.5 store per year
Answer:
the probability that exactly 1 received a special accommodation is 0.3079
Step-by-step explanation:
Step 1: define the variable
x= the number of students who received a special accommodation.
Step 2: define the distribution of this variable
x ~ binomial distribution ( p=0.02, n=25)
this is because x is the number of succes in 25 trials.
Step 3: using the binomial distribution formula
P(x=1)= (25C1)*(0.05^1)*(1-0.05)^(25-1)=0.3079
where (25C1) is a combination
