Answer:
y=4x-1
Step-by-step explanation:
Answer:
y = 0x + 2
Step-by-step explanation:
Find the slope.
Slope = <u> y2 - y1</u>
x2 - x1
Plug in the points.
Slope = <u>2 - 2</u> = <u>0</u>
-7 - 8 -15
Pick a point to plug into the y = mx + b formula
I picked (8,2)
Now plug in the point and slope.
(Your teacher might prefer you to use 0/-17, but it can be simplified to 0, so I'll just use that.)
Equation: (2) = 0(8) + b
2 = 0 + b
2 = b (b = 2)
Now put your slope and the y-intercept into the equation, and it will be:
y = 0x + 2
It's a bit hard to show on keyboard, so I hope you understand.
Answer:
the inequality would be, b/3<=16
Step-by-step explanation:
The slope is 0.5 tablespoon per minute, which you can deduct from the increase of y from one minute to the next.
The initial value (at x=0) is 1. So the equation is:
y = 0.5x + 1. That's the last one in the list, answer D.
Answer: C- Fail to reject the null hypothesis. There is not enough evidence to oppose the company's claim.
<u><em>Note: I'm not sure this is correct o_O

I used a graphing calculator and calculated the t-interval of the jellybean sample using a 99% confidence level:
<em>tInterval 9.68,1.23,125,0.99</em>
It resulted in 9.68 ± 0.287805.
Therefore, we're 99% confident that the weight number of jellybeans would lie between 9.3922 oz and 9.9678 oz.
A weight of 9.45 oz lies within this range, therefore, it is possible that the candy company's claim is true.
