Answer:
2) B. as x increases, y increases as well
3) C. Number of books owned and number of visits to the doctor's office in one year
4) D. The 90 minute lesson that cost $40
5) A. There is a strong correlation
Step-by-step explanation:
2) i am not 100%positive since there is no way to check my answer, but i believe it is "B. As x increases, y increases as well" because it highlights the correlation between x and y.
(i already explained 3, 4, and 5 on another one :D)
Y = 6, z = 2
~Hope this helped!~
(The first page is the beginning of the equation, and the next page is the ending)
The problem is about converting a decimal into a fraction, and simplify it:
<span>0.40 = 0.4 = four tenths = 4/10 = 2/5
that is the simplest fraction</span>
Answers:
Angle A = 104 degrees
Angle B = 76 degrees
=================================
Supplementary angles add to 180 degrees.
A+B = 180
(3x-7)+(2x+2) = 180
5x-5 = 180
5x-5+5 = 180+5 ... add 5 to both sides
5x = 185
5x/5 = 185/5 .... divide both sides by 5
x = 37
Use x =37 to find
Angle A = 3x-7 = 3*37-7 = 111-7 = 104 degrees
Angle B = 2x+2 = 2*37+2 = 74+2 = 76 degrees
As a check: A+B = 104+76 = 180 so that helps confirm the answer
