How do you solve a linear equation
Olenka [21]
It is hard to explain without a picture. You have the line graph and depending on what your numbers are, you place them where the teacher, (or paper) says too. You would then move two to the right, and one up. You would keep repeating that pattern until you got to the top of the graph. After that you would draw a strait line through it. If you are dealing with negative numbers, then depending on which one is negative, you would move two to the LEFT from the starting point and go one up. You repeat that pattern as well, then once you reach the top of the page you draw a line through it.
I hope this helped!

The null hypothesis claims that the proportion of community college students who work full-time is 0. 45. The alternative hypoth
diamong [38]

The stronger the evidence is against the null hypothesis, the higher the divergence from it.

What do you mean by null hypothesis ?

A statistical hypothesis known as a null hypothesis asserts that no statistical significance can be found in a collection of provided observations. Using sample data, hypothesis testing is performed to judge a theory' veracity. It is sometimes referred to as just "the null," and its symbol is H_{0}. To determine if a theory regarding markets, investing methods, or economies is correct or wrong, quantitative analysts employ the null hypothesis,

The null hypothesis states that the percentage of the population who works full time is 0.45.

As a result, 450 persons who are randomly selected from a population of 1000 work full-time.

A different hypothesis states that the ratio is higher than 0.45.

In the options provided, the proportion for the first option is 300/1000, or 0.3.

In the second choice, 500/1000 equals 0.5

Third alternative: 700/1000 = 0.7

Therefore, the stronger the evidence is against the null hypothesis, the higher the divergence from it.

The sum of two numbers is 49 and the difference is 25 . What are the numbers?
OLEGan [10]

Answer:

x = 37 y = 12

Step-by-step explanation:

Let x be one number

Let y = other number

x+y = 49

x-y = 25

Add the equations together

x+y = 49

x-y = 25

---------------

2x = 74

Divide by 2

2x/2 = 74/2

x =37

x+y = 49

37+y = 49

Subtract 37 from each side

37+y-37 = 49-37

y = 12
