Answer:
Step-by-step explanation:
The chi-square test is majorly used to test relationship/association between two categorical variables. The use of the chi square test is to ask the question: if there is a significant relationship between company A and B.
But this study only aims to compare company A and B cell phone service and not to establish a relationship between the two company's cell phone service
It would be 12 weeks because if you multiply 5 by 12 then you would get 60 and 60min equals and hour.
Answer:
it equals 16.6 repeating, rounds to 16.7, or you could leave it as an improper fraction 50/3
Step-by-step explanation:
Answer:
Step-by-step explanation:
A)
Dilation. Since it's only the size of the figure that's changing
B)
Height of the smaller one: 4
Width of the smaller one: 6
Height of the bigger one: 6
Width of the bigger one: 9
6/4 = 1.5
9/6 = 1.5
Since both 6/4 and 9/6 was 1.5, that means that the Width and Height was proportional and that the two trapezoids is at a ratio o:
1 : 1.5
One unit of the smaller one is 1.5 units on the bigger one.
<u>A. X=0 Y=5</u>
Those 2 equations are a system. You answer is the value of x and y.
13x+3y=15
y=5-4x
First, lets make each equation fit into y=mx+b
13x +3y=15 y=5-4x
-13x -13x y=-4x+5
3y= -13x +15
Let's use the elimination method to solve this.
y= -4x+ 5 multiply top by 3
3y=-13x+15
3y=-12x+15
3y=-13x+15 subtract the equations
<u>0=x</u>
Lets use the x we just found to solve for y.
y=4x+5
y=4(0)+5
<u>y=5</u>
