Answer:A. on edge
Step-by-step explanation:
Just took the quiz.
For there to be 1 car, we consider two possible outcomes:
The first door opened has a car or the second door opened has a car.
P(1 car) = 2/6 x 4/5 + 4/6 x 2/5
P(1 car) = 8/15
For there to be no car in either door
P(no car) = 4/6 x 3/5
P(no car) = 2/5
Probability of at least one car is the sum of the probability of one car and probability of two cars:
P(2 cars) = 2/6 x 1/5
= 1/15
P(1 car) + P(2 cars) = 8/15 + 1/15
= 3/5
The number of students in 5th grade is 60, since 24% of 250 is 60.
Since 90 is 38% if 250, 38 is going to be the percent of all students in sixth grade.
20% of 250 is 50, so the percent of all students in seventh grade is 50.
Finally, 45 is 18% of 250, so 18 percent of all students are in eight grade.
Hope this helped :)
Mavis drives = 634 miles.
Mavis visits her grandmother 4 times.
That means, she drives 634 miles each time when she visits her mother.
One time round trip Mavis's house to her gramdmother in philadelphia = 634 miles.
If she visited 4 times, we can multiply one round trip distance by 4 or we can just add that distance four times.
Let us try it by multiplying 4 by 634 .
If we multiply 4 by 634, we get 2536.
Therefore, 2536 miles Mavis drives if she visits her grandmother 4 times.
5000*0.03+0.05x=275
Solve for x
X=2500
The answer is b
