Answer is 88.2

The bottom side is 500 units, so is the top side which is parallel to the bottom side.
We'll use the tangent function as we know the adjacent side is 500 and the opposite side is the unknown x.
tan(angle) = opposite/adjacent
tan(10) = x/500
500*tan(10) = x
x = 500*tan(10)
x = 88.16349 ... use a calculator (make sure you are in degree mode)
x = 88.2 ... rounding to one decimal place
So its asking you to find the gravity on earth relative to the gravity on mars.
Set up an equation to figure out the difference between the two gravities
x=.38
I don't know what constant of proportionality is in this context but a ball on mars would weigh .38 the amount that it does on earth.
The best way for him to check his answer would be to simply plug in the value found for x into the equation.
4(2) - 6 = 2
8 - 6 = 2
2 = 2
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.
