The equation 7x + 3x - 18 = 6(x+3) is 9

<h3>What is equation?</h3>

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

given:

7x + 3x - 18 = 6(x+3)

7x + 3x - 18 = 6x+18      [Distributive Property]

10x-18= 6x+18               [Addition Property of Equality]

10x-6x= 18+18               [Combine Like Terms ]

4x=36                            [Subtraction Property of Equality]

4*x=36                            [Multiplication Property of Equality]

x=36/4                           [Division Property of Equality]

x=9

Determine whether the following statement regarding the hypothesistest for two population proportions is true or false.
murzikaleks [220]

Answer:

False

Step-by-step explanation:

Let p1 be the population proportion for the first population

and p2 be the population proportion for the second population

Then

H_{0} p1  = p2

H_{a} p1 ≠ p2

Test statistic can be found usin the equation:

z=\frac{p1-p2}{\sqrt{{p*(1-p)*(\frac{1}{n1} +\frac{1}{n2}) }}} where

  • p1 is the sample population proportion for the first population
  • p2 is the sample population proportion for the second population
  • p is the pool proportion of p1 and p2
  • n1 is the sample size of the first population
  • n2 is the sample size of the second population.

As |p1-p2| gets smaller, the value of the <em>test statistic</em> gets smaller. Thus the probability of its being extreme gets smaller. This means its p-value gets higher.

As the<em> p-value</em> gets higher, the null hypothesis is less likely be rejected.

What would my GPA be? Here are my grades.
marta [7]
That is approximately, in order, a C, a C, a B, a D, an A, a B, and an A.

In grade points that is a 2, a 2, a 3, a 1, a 4, a 3, and a 4.

The average of those numbers is about 2.7, so you have a 2.7.

You can raise that by bringing up the D as it is an outlier here.
