Simplify the expression below. 2^3 x 2^2

Zigmanuir [339]

Answer:

$32$ $or~2^5$

Step-by-step explanation:

→ $(2^3)(2^2)$

$=2^3*2^2$

$=(2*2*2)*(2*2)$

$=2*2*2*2*2$

$=32$

You can also put this in another way:

 $2^5=2^3*2^2=2^3^+^2=2^5$

A population of values has a normal distribution with μ = 158.9 μ = 158.9 and σ = 90.4 σ = 90.4 . You intend to draw a random sa

rosijanka [135]

Answer:

$P_{39}=133.68$

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 158.9

Standard Deviation, σ = 90.4

We are given that the distribution is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

We have to find the value of x such that the probability is 0.39

$P( X < x) = P( z < \displaystyle\frac{x - 158.9}{90.4})=0.39$

Calculation the value from standard normal z table, we have,

$\displaystyle\frac{x - 158.9}{90.4} = -0.279\\\\x = 133.6784\approx 133.68$

$P_{39}=133.68$

133.68 separates the bottom 39% means from the top 61% means.
