Answer:
852 miles
Step-by-step explanation:
We presume the speed is constant, so the satellite will travel 3/8 the distance in 3/8 the time.
... d = (3/8)·(2272 miles) = 852 miles
_____
1 minute is 1/8 of 8 minutes, so 3 minutes is 3/8 of 8 minutes.
Answer:
a) 4w + 16 = 50.
Step-by-step explanation:
The garden's length is obviously 8 feet longer than the width. If width were represented by w, the length would be w + 8.
We are calculating the perimeter, which is 2 times the length plus 2 times the width. That adds up to be 50.
2(w) + 2(w + 8) = 50
2w + 2w + 16 = 50
4w + 16 = 50
So, the answer is a) 4w + 16 = 50.
Hope this helps!
Answer:
0.9936 is the probability that the student will fail.
Step-by-step explanation:
We are given the following information:
We treat adult guessing correct answer as a success.
P(guess correct answer) = 0.2
Then the number of correct guesses follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 10
The student needs atleast 6 correct answer to pass the test. We have to calculate the probability that the student will fail.
We have to evaluate:
0.9936 is the probability that the student will fail.
