For a population with = 100 and = 20, what is the x value corresponding to z = 1.50?
mafiozo [28]

For a population with mean (μ) = 100 and standard deviation (σ) = 20, the X value corresponding to z = 1.50 is 130.

<h3>What is a z-score?</h3>

A z-score is also referred to as a standard score and it's a measure of the distance between a raw score and the mean, when standard deviation units are used.

<h3>How to determine the value of x?</h3>

In Statistics, the standardized z-score is giving by this formula:

Z=\frac{\bar{x}\;-\;\mu}{ \sigma }

Making x the subject of formula, we have:

x = Zσ + μ

Substituting the given parameters into the formula, we have;

x = 1.50(20) + 100

x = 30 + 100

x = 130.

(-4t^5) (-10t) NEED AN ANSWER VERY SOON !! PLEASE HELP!!!!
hammer [34]

Answer:

40t⁶

Step-by-step explanation:

Since -4t⁵ and -10t have the same variable (base), we can multiply their coefficients (numbers) and add their exponents

-4t⁵ * -10t = 40t⁶

Since both numbers are negative, when we multiply them, they cancel out.

SInce both variables are the same (both are t), we can just add their exponents together. Even though we don't see an exponent above -10t, we can assume that it is 1. Think of it as this, -10t = -10t¹ because it just represents -10t, -10t (specifically the t) isn't being multiplied by anything.
