Answer:
Step-by-step explanation:
R is the event of getting a red jelly bean. 22 out of the 150 jelly beans are red. That means it is a chance of getting a red jelly bean.
Simplified that is
Option B:
Solution:
Given sound level = 120 decibel
To find the intensity of a fire alarm:
where
Step 1: First divide the decibel level by 10.
120 ÷ 10 = 12
Step 2: Use that value in the exponent of the ratio with base 10.
Step 3: Use that power of twelve to find the intensity in Watts per square meter.
Now, do the cross multiplication,
Option B is the correct answer.
Hence .
You factor the expression first leaving you with
Then you would cancel out 3xy as because there is exactly one on each side. This, in turn, would leave you with
z - 1
5.19 / 16.8 = <span>0.30892857142</span>
You just multiply 16 and 3 and it gives you 58
