84
Step-by-step explanation:
8x6=48
2x4=8

The area of a circle is given by

If you want to approximate pi with 3.14, the formula becomes

Answer: 0.625
Step-by-step explanation:
Given : The waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed with interval= [0 minutes, 6 minutes]
The probability density function :-

The interval of required event = [2.25 seconds, 6 seconds]
Now, the probability that a randomly selected passenger has a waiting time greater than 2.25 minutes is given by :-

Hence, the probability that a randomly selected passenger has a waiting time greater than 2.25 minutes = 0.625
(3x + 2) < -7 or (3x + 2 >7
Explanation/Step by step:
We have| |3x +2| >7
We divide the absolute value inequality into two inequalities
First Inequality (Which is Positive Value)
(3x + 2) >7
Second inequality (Which is the Negative Value)
-(3x + 2) >7
Then you Multiply by- 1 both sides
~And Remember that when you multiply or divide both sides of an inequality by a negative number you must reverse the inequality Symbol.~
So which that be said it would look like this:
(3x +2) < -7
So therefore (3x + 2) < -7 or (3x + 2) >7
Hope this makes since to you!!
I hope this helps as well..
