Answer:
16
Step-by-step explanation:
When the hypotenuse is given, you can use this formula to solve for the leg
b = root c^2 - a^2
b = root 20^2 - 12^2
b = 16 in
Hope this helps!

Answer:
a) 0.0016
b) 0.0224
Step-by-step explanation:
If every question has 5 possible answers, the probability of getting the correct answer by guessing would be 0.20. The probability of getting an incorrect answer would be 0.80.
a)Find the probability she lucks out and answers all four questions correctly.
To do this, Allison would have to guess right the first, second, third AND fourth answers. Therefore, we have to multiply the probabilities:
0.20 x 0.20 x 0.20 x 0.20 = 0.0016
The probability that she answers all 4 questions correctly is 0.0016.
b) Find the probability that she passes the quiz.
To pass the quiz, she has to have three OR 4 correct answers:
- The probability that she has 3 correct answers is: 0.20 x 0.20 x 0.20 x 0.80 (since she has to have 1 correct answer and 1 incorrect one) = .0064.
- We already calculated the probability that she guesses 4 answers correctly: 0.0016.
Now, we have to sum up these two scenarios:
0.0064 + 0.016 = 0.0224.
Thus, the probability that she passes the quiz is 0.0224
Lets start with the algebraic equation
5x=15
you want to isolate the variable in the equation so you end up with x= ...
x is being multiplied by 5, in order to cancel out the 5 divide the entire equation by 5 (BOTH SIDES OF THE EQUATION)
5x=15
———
5
5x becomes x
15 becomes 3
you are left with x=3
Exact form: 15/2
decimal form: 7.5
mixed number form: 7 1/2
