Answer:
Step-by-step explanation:
P(a or b) = P(a) + P(b) - P(a and b)
0.88 = 0.70 + 0.60 - P(a and b)
P(a and b) = 1.30 - 0.88 = 0.42.
So the events a and b are not mutually exclusive.
Answer:
we're just multiplying X × 2 every time so (y=80)
Hello there!
Start by asking yourself:"How to find the percentage of a number?"
We need to use the equation y = P% * x
In this case, the y is 20%
Y = P% * X
Y = 20% * X
Now we need to convert the percentage to decimal
P = 20%/100
P = 0.2
Then go back to the equation
Y= 0.2 * 5
Y = 1
The answer is 1
I hope the steps are easy to understand and hopefully the answer helps!

Answer:
-50x + 600 = 250
Step-by-step explanation:
10x + 60(10-x) = 250
10x + 600 - 60x = 250
-50x + 600 = 250
