6n + 9
Step-by-step explanation:
6 times a number can be written as "6n"
9 more than 6n can be written as 6n + 9
Answer:
1. c = 13
2. a = 20
Step-by-step explanation:
1. 12² + 5² = x²
144 + 25 = x
144 + 25 = 169
√169 = 13
2. 29² - 21² = x²
841 - 441 = x
841 - 441 = 400
√400 = 20
25.8 because y = 2 so yeaaaa
To solve this, we use the z-test.
z = (x – u) / σ
when x = 450
z = (450 – 550) / 100
z = -1
We use the standard distribution tables to find for P.
P = 0.1587
Since we are looking for values greater than x = 450,
therefore:
1 – 0.1587 = 0.8413
This means that 84.13% have bladder volume larger than 450
mL.
