Answer:
Step-by-step explanation:
<u>Use two points on the graph to get an equation:</u>
<u>The slope</u>: m = (60 - 8)/6 = 8.667
<u>The y- intercept</u> is 8
<u>The equation of the line of best fit:</u>
Answer:
y=-4x+19
Step-by-step explanation:
Plug into point-slope formula
y-y1=m(x-x1)
y-(-1)=-4(x-5)
y+1=-4x+20
-1 -1
y=-4x+19
1) order them from least to greatest. (0.2, 0.3, 0.4, 0.7, 0.9, 0.9)
2) Take the largest number and smallest number and find the difference. 0.9-0.2=0.7
3) answer is 0.7
For this case we must complete squares:

We add the square of half the coefficient of the term "x",
on both sides of the equation:

According to the perfect square trinomial we have:

Rewriting the expression we have:

OKOK
A salesperson averaged $120 per 10 days sooo 120/10 is 12 so about 12 per day
So,
You guess the amount that could make up a number around 150or 160
So 12 x3 = 36 + 120=156 hallelujah!
So, 3 more days until she can average $160 in order to bring her overall average to 150%.....
Hope this helps. :::)))))
