Answer:
Close to zero
Step-by-step explanation:
In chi Square test, we accept the hypothesis If the sum of the weighted squared deviations is small.
This is because If the sum of the weighted squared deviations is small, it will mean that the observed frequencies will be close in value to the expected frequencies and therefore, there would be no need to reject the the hypothesis. However, when the sum is large, there will be need to question the hypothesis or claim made.
Thus, the hypothesis may be accepted if the difference between observed and expected results is close to zero

Solve for x: -3x - 12 = 15
Answer:
x = -9
Step-by-step explanation:
Add 12 to each side, so it now looks like this: -3x = 27Divide each side by -3x, so it now looks like this: x = -9I hope this helps!
Answer:
-3x-12=15
-3x=15+12
-3x=27
-3/-3x=27/-3
x=-9

Given:
Length of a rectangle = (3x-3)
Width of the rectangle = (2x+1)
To find:
The area of the rectangle.
Solution:
We know that, area of a rectangle is
[tex]Area=Length \times width[/tex]
Putting Length = (3x-3) and width = (2x+1), we get
[tex]Area=(3x-3)\times (2x+1)[/tex]
[tex]Area=(3x-3)(2x+1)[/tex]
Using distributive property, we get
[tex]Area=3x(2x+1)-3(2x+1)[/tex]
[tex]Area=3x(2x)+3x(1)-3(2x)-3(1)[/tex]
[tex]Area=6x^2+3x-6x-3[/tex]
[tex]Area=6x^2-3x-3[/tex]
Therefore, the area of rectangle is [tex](3x-3)(2x+1)\equiv 6x^2-3x-3[/tex] sq. units.

If Anna walked to Liz's house and back, she would cover a distance of
16 blocks.
How to determine the distance between the coordinates for each points?In Mathematics and Geometry, the distance between two (2) end points that are on a coordinate plane can be calculated by using the following mathematical equation:
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Where:
x and y represent the data points (coordinates) on a cartesian coordinate.
Note: Each interval on the coordinate plane represent 1 unit.
By substituting the given end points into the distance formula, we have the following;
Distance = √[(5 - 5)² + (-4 - 4)²]
Distance = √[(0)² + (-8)²]
Distance = √[0 + 64]
Distance = √64
Distance = 8 units.
To and from distance is given by;
Distance = 2 × 8
Distance = 16 blocks.

Tyler’s brother works in a shoe store.
Tyler’s brother earns a commission. He makes 2.5% of the amount he sells. Last week, he sold $900 worth of shoes. How much was his commission?
Answer:
Step-by-step explanation:
A) To figure this out, convert 2.5% into a decimal, which is 0.025. Then, multiply the amount he sold by his commission percent. So $9000 * 0.025 =$225
B) The formula for percent change (or in this case percent markup) is (new value - old value)/old value *100%. So, (80-50)/50*100% = 30/50*100%=60%.
C) First, calculate the amount his hourly rate will increase by. So, multiply 12 by 5%, which is $12*0.05=$0.60. Then, add this amount to his current hourly rate. So he now makes $12.60.

the slope intercept of (0,1) and (3,0)
Answer:
-1/3
Step-by-step explanation:
To find slope intercept, it's (y2 - y1) / (x2 - x1). It can also be (y1 - y2) / (x1 - x2) as long as you're consistent.
Plugging the x and y values in using the first equation, you get (0 - 1) / (3 - 0) = -1/3.
