34% of the scores lie between 433 and 523.
Solution:
Given data:
Mean (μ) = 433
Standard deviation (σ) = 90
<u>Empirical rule to determine the percent:</u>
(1) About 68% of all the values lie within 1 standard deviation of the mean.
(2) About 95% of all the values lie within 2 standard deviations of the mean.
(3) About 99.7% of all the values lie within 3 standard deviations of the mean.
Z lies between o and 1.
P(433 < x < 523) = P(0 < Z < 1)
μ = 433 and μ + σ = 433 + 90 = 523
Using empirical rule, about 68% of all the values lie within 1 standard deviation of the mean.
i. e.
Here μ to μ + σ =
Hence 34% of the scores lie between 433 and 523.
Answer:
x = 6
Step-by-step explanation:
First, separate the problem into
Then, Subtract 9 from both sides of the equation.
Simplify.
Multiply 3 to each side, which will give you -2x = 4x - 36
Subtract 4x from each side -2x - 4x = 4x - 36x - 4x
Combine like terms: -6x = -36
Divide both sides by -6
Your answer should be 6
