Answer:
go to photo math
Step-by-step explanation:
Let, the Age of Michelle = x
Age of Steve = x + 15
After 8 years, (x + 15 + 8) = 2(x + 8)
x + 23 = 2x + 16
2x - x = 23 - 16
x = 7
So, x + 15 = 22
In short, Age of Michelle is 7 & Age of Steve is 22 Years
Hope this helps!
Answer:
1. P(A|B) - option 2
2. does not affect - option 2
3. P(A) - option 1
Step-by-step explanation:
By the definition, the notation P(A|B) reads the probability of event A given that event B has occured. So, for the first gap correct choice is 2 - P(A|B).
If events A and B are independent, then the probability of event B occuring does not affect the probability of event A occuring. So, for the second gap correct choice is 2 - does not affect.
Events A and B are independent, then

Use formula for the conditional probability:

Since events A and B are independent, we get

So, for the third gap correct answer is 1 - P(A)
The measures of the angles are 30, 60 and 90 degrees.
Explanation:
I assume the question should read "the measures of the ANGLES of the triangle are in the ratio 2:4:6.
If the angles are in the proportion 2:4:6, the measures of the angles have the same scale factor
x
. And, the sum of the measures of the angles of a triangle is
180
.
