Answer:
Step-by-step explanation:
Given
The attached probability distribution of x
Required
Find 
To do this, we consider all values of x less than or equal to-3.
So, we have:
From the table:
So, the equation becomes
Answer:
-2
Step-by-step explanation:
If x were -22, then you are dividing by -2 + 2, which equals 0. You can't divide by 0.
If both the hoses are on the same time then the height of the water in the pool is given by the expression 15g^2 + 5g - 6
Step-by-step explanation:
(7g^2 + 3g - 4) + (8g^2 + 2g - 2)
= (7g^2 + 8g^2) + ( 3g + 2g) + (-4 -2)
with the help of distribution law,
= (7 +8)g^2 + (3 + 2)g - (4 + 2)
= 15g^2 + 5g - 6
Therefore if both the hoses are on the same time then the height of the water in the pool is given by the expression 15g^2 + 5g - 6
Answer && Step-by-step explanation:
I will justify steps. (1/2)s == s/2
s/2=112
mult 2 to each side
=> s=112*2
s=224
