It is a quadratic equation, if it is equal to zero. It is not factor able.
To find the perfect square needed, you take the "middle" value and half it, then square it. so in this case, take -6, half it into 3, and square it to get 9. you'll be adding 9 to both sides
Using the formula:
V= 1/6 πd^3
V ≈ 1838.78
Answer:
The value is
Step-by-step explanation:
From the question we are told that
The mean is
The standard deviation is
The safest water level is between 7.2 and 7.8
Generally the probability that the selected pool has a pH level that is not considered safe is mathematically represented as
Here
Generally
So
=>
From the z-table the probability of (Z < -1.5) and ( Z <1.5) are
and
So
So
=>
Answer:
(A) 22
(B) 12
