Answer:
27
Step-by-step explanation:
First, subtract 8 from 143 which would give you 135. You then divide 135 by 5 and you get 27
Answer:
The answer is explained below
Step-by-step explanation:
Given that:
mean (μ) = 7 and standard deviation (σ) = 1.5.
The z score is used in statistic used to measure the number of standard deviation by which the raw score is above or below the mean value. It is given by:

To find the Probability that x < 8.8, we first find the z score using:

From the z tables, P(x < 8.8) = P(z < 1.2) = 0.8849 = 88.49%
What you have to do is rearrange the equation by subtracting what is on the right of the equal sign from both sides of the equation
so it would be 4*x-13*x-(27)=0
Answer:
The mean is 7
Step-by-step explanation:
5,5,7,7,9,13
9-7 is going to get 7
Answer:
Before we can simplify radicals, we need to know some rules about them. These rules just follow on from what we learned in the first 2 sections in this chapter, Integral Exponents and Fractional Exponents.
Expressing in simplest radical form just means simplifying a radical so that there are no more square roots, cube roots, 4th roots, etc left to find. It also means removing any radicals in the denominator of a fraction
