Let's find all the prime numbers.
1,3,5,7,9,11,13,15,17,19
They are not divisible by 2.
Put that into a fraction, where the amount of numbers is the numerator and the total amount of numbers is the denominator.
10/20
That is half of 20.
So, 50% of the 20 first natural numbers are prime.
I hope this helps!

Answer:
y=y
Step-by-step explanation:
Assuming the question is to simplify:
Add 3x and 2x on the left side
5x+2y+2=3x+2x+2
Add 3x and 2x on the right side
5x+2y+2=5x+2y+2
Move all terms containing x to the left side of the equation
Subtract 5x from both side
5x+2y+2-5x=2y+2
x cancel out
2y+2=2y+2
Moving the constant to the right side of the equation
2y=-2+2y+2
Simplify
2y=2y
Divide 2
y=y
Answer:
88
Step-by-step explanation:
Basically you look at the number after the decimal point and if it is below 5 it will turn to 88. If it is over 5 it will be a 89. For this you also ignore the 7. The 7 does not mean anything.
<span>Assuming that Josh throws the discus 36 times, the expected value of y will be the length each discus reaches for each throw all added together. Specifically, it will be discus throw one, plus discus throw two -- all the way to discus throw thirty-six. Adding all of those throws together will provide the expected value of Y.</span>
