Answer:
x ≈ 17.32, y = 20
Step-by-step explanation:
sin (30°) = 10/y
=> y = 10/sin (30°)
=> y = 20
x = [tex]\sqrt{20^{2} - 10^{2}}[/tex]
=> x ≈ 17.32

Before they graduate from Great Lakes High School, all 12th grade students fill out a survey about their future college plans.
Are you attending an in-state college after high school graduation?
Will you begin college during the summer semester?
The same group of students are asked to answer yes or no to both questions. The students’ responses were recorded on the table below.
Determine the probability that a student will begin college during the summer semester and attend an in-state college.
Determine the probability that a student will begin college during the summer semester given that he is attending an in-state college.
The probability is P = 0.894
How to get the probabilities?
a) Determine the probability that a student will begin college during the summer semester and attend an in-state college.
The probability is given by the quotient between the number of students that start on summer semester and attend to an in-State college, and the total number of students that start on the summer semester.
The number of students starting on the summer semester is:
178 + 21 = 199
Of these 199 students, 178 will attend to an in-state college, so our probability is:
P = 178/199 = 0.894

A donkey eats three fifths of a hay bale a week.
How many bales does he eat in 10 weeks?
Answer:
Step-by-step explanation:
the donkey eats 3/5 of hay bale a week
3/5 x 2 = 6
the donkey eats 6 hay bales in 10 weeks
The amount of bales the donkey eats in 10 weeks is 6 bales.
Given,
A donkey eats three-fifths of a hay bale a week.
We need to find out how many bales he eats in 10 weeks.
How do we compare two quantities?Example:
2 miles in 1 hour
2 miles = 1 hour
To find miles in 4 hours we multiply both sides by 4.
4 x 2 miles = 4 x 1 hour
8 miles = 4 hours
We have,
Donkey eats:
3/5 bales = 1 week ____(1)
In 10 weeks:
Multiply 10 on both sides of (1)
10 x 3/5 bales = 10 x 1 week
6 bales = 10 weeks
Thus the amount of bales the donkey eats in 10 weeks is 6 bales.
