Answer:
no, because the runner is short by 480 feet
Step-by-step explanation:
there are 5280 feet in 1 mile
5280 feet= 1 mile 20 feet= 1 second (times by 240)
4800 feet= 240 seconds
he is 5280-4800= 480 feet less

This is the Equation: 2x + 6
Answer:
Correct option is C). {(0, −5), (2, 9), (−3, −26)}
Step-by-step explanation:
Given function is f(x)=7x-5.
Here, Options are given ordered pair
Let, x=0
f(x)=7x-5
f(0)=7(0)-5
f(0)=(-5)
The ordered pair is (0,-5)
Let, x=2
f(x)=7x-5
f(2)=7(2)-5
f(2)=9
The ordered pair is (2,9)
Let, x=(-3)
f(x)=7x-5
f(-3)=7(-3)-5
f(-3)=(-26)
The ordered pair is (-3,-26)
Thus, Correct option is C). {(0, −5), (2, 9), (−3, −26)}
Answer:
64.65% probability of at least one injury commuting to work in the next 20 years
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval.
Each day:
Bikes to work with probability 0.4.
If he bikes to work, 0.1 injuries per year.
Walks to work with probability 0.6.
If he walks to work, 0.02 injuries per year.
20 years.
So
Either he suffers no injuries, or he suffer at least one injury. The sum of the probabilities of these events is decimal 1. So
We want . Then
In which
64.65% probability of at least one injury commuting to work in the next 20 years
Answer:4
Step-by-step explanation:3-8=-5. But because it is in absolute value, it would be positive 5. And then 5-1=4.
