Answer:
$50.23
Step-by-step explanation:
f(t)=1.35(t)+9.73
First I found out how many years are after 1985 so you would do 2020-1985 which equals 30.
I plug it in for t.
f(t)=1.35(30)+9.73
Then you multiply 1.35 and 30 which would leave us with.
f(t)=40.5+9.73
Add them and you get $50.23

Answer:
72.25 ft
Step-by-step explanation:
The function that models the height of the ball is
The maximum height occurs at:
We substitute t=2.125 to get:
The maximum height is 72.25 feet
Answer:
The probability that at most 38 of the 60 relays are from supplier A is P(X≤38)=0.3409.
Step-by-step explanation:
We can model this question with a binomial distribution random variable.
The sample size is n=60.
The probability that the relay come from supplier A is p=2/3 for any relay.
If we use a normal aproximation, we have the mean and standard deviation:
The probability that at most 38 of the 60 relays are from supplier A is P(X≤38)=0.3409:
So first identy the type of series by looking at the relationship, in this case it is arithmetic!
So we know it adds up by the same thing everytime which is 3/40!
Next number will be...27/40 +3/40= 30/40
Simplify 30/40, divide by 10 both 30 and 40 to get........ 3/4
So next fraction is 3/4
