Find the value
of 6y^2 - 24y - 51 when y=-2
Answers
Answer:

Step-by-step explanation:
6(y^2) - 24y -51 = 6 4 - 24y - 51
(6 4) - (24y) - 51 = 24 - -48 - 51
(24 - -48) - 51 = 72 - 51

A set of biology exam scores are normally distributed with a mean of 70 points and a standard deviation of six points X equal the score on a randomly selected exam from the set find P(X< 73)
Answers
Answer: .69
Step-by-step explanation:
Answer on khan
We can write the value in the range P(64 < {x} < 76) as 0.68.
What is standard deviation?In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values.
Given is that a set of biology exam scores are normally distributed with a mean of 70 points and a standard deviation of six points X equal the score on a randomly selected exam from the set.
It is given that -
μ = 70
σ = 6
For the range of {x}, we can write -
(μ - σ) < {x} < (μ + σ)
64 < {x} < 76
We can write the range of {z} value as -
(64 - 70)/6 < {z} < (64 + 70)/6
- 1 < {z} < + 1
Now -
P(64 < {x} < 76) = P(x < 76) - P(x < 64) = 0.84 - 0.15 = 0.68
Therefore, we can write the value in the range P(64 < {x} < 76) as 0.68.
