Answer:
19 situps
Step-by-step explanation:
Given that the regression equation to find a a relationship between hours of TV watched per day (x) and number of situps a person can do (y) was done.
The result was
y = ax+b
Correlation coefficient = 0.865
To predict the number of situps a person who watches 3 hours of TV
y = -1.23(3)+22.738
= 19.048
Approximately 19 situps.
For this case we have that by definition, the area of a triangle is given by:
Where:
h: It's the height of the triangle
b: It is the base of the triangle.
They tell us that the height of the triangle is 3 units more than the base. That means that if the base is "b" then the height is "b + 3". So, the area is:

Option C
4/3* m^21/12* n^8/3
you need to use enough of laws of indices
Answer: (x²-6)(x²+6)
Step-by-step explanation:
1. Look at 36 and determine if there is any factors that will make cancel out the middle term in the polynomial. Which in this case you would be able to use 6.
2. Next, we will reduce the x⁴ into x² since if you multiply x² • x² you will get x⁴ since you add exponents when multiplying.
3. Factor into to binomials which would be (x²−6)(x²+6) and if you want to simplify down further set each equation to 0 and solve and once you do that you would get x=±√6 for x²−6 but for x²+6 it would be imaginary because you can’t square root negative numbers, so in this case it would be −√6i and √6i.
Well, all you need to do is divide $3.50 into 5 (because that means you are cutting it smaller, 5 ÷ 5 = 1, and you are dividing five 5 times)
