Assume that adults have IQ scores that are normally distributed with a mean of mu equals μ=105 and a standard deviation sigma eq
Over [174]

The probability that a randomly selected adult has an IQ less than

135 is 0.97725

Step-by-step explanation:

Assume that adults have IQ scores that are normally distributed with a mean of mu equals μ = 105 and a standard deviation sigma equals σ = 15

We need to find the probability that a randomly selected adult has an IQ less than 135

For the probability that X < b;

  • Convert b into a z-score using z = (X - μ)/σ, where μ is the mean and σ is the standard deviation
  • Use the normal distribution table of z to find the area to the left of the z-value ⇒ P(X < b)

∵ z = (X - μ)/σ

∵ μ = 105 , σ = 15 and X = 135

∴ z=\frac{135-105}{15}=2

- Use z-table to find the area corresponding to z-score of 2

∵ The area to the left of z-score of 2 = 0.97725

∴ P(X < 136) = 0.97725

The probability that a randomly selected adult has an IQ less than

135 is 0.97725

When 16x3 - 12x2 + 4x is divided by 4x, the quotient is
Advocard [28]
\frac{16x^{3} - 12x^{2} + 4x}{4x} = \frac{16x^{3}}{4x} - \frac{12x^{2}}{4x} + \frac{4x}{4x} = 4x^{2} - 3x + 1 \\\\The\ answer\ is\ 4.

Solve for x: 3x − 24 = 81
Ludmilka [50]
If you would like to solve for x: 3x - 24 = 81, you can do this using the following steps:

<span>3x - 24 = 81
</span>3x = 81 + 24
3x = 105
x = 105 / 3
x = 35

The correct result would be 35.
