Answer:
y=7/5x+7
Step-by-step explanation:
Use the saying "rise over run" to find the slope. If we go from the bottom most dot, we have to rise 7 and run 5 to reach the next dot, making the slope 7/5.
Next, we have to find the y-intercept. Do this by locating where the line crosses the y-axis, in this case it is at 7.
Finally, plug these numbers into slope-intercept format: y=mx+b (m is slope, and b is y-intercept).

Steps:
3.95(3) + 8.95b = 47.65
<span>11.85 + 8.95b = 47.65
</span>
Now just subtract 11.85 from both sides and now the equaton shoud look like this
8.95b = 35.8
Now divide 8.95 from both sides and you get...
b=4
Hope this helps!
Answer:
Step-by-step explanation:
I DONT KNOW
Theoretical probability is what you would expect the result of an experiment would be. For example if you tossed a fair coin 10 times the theoretical result would be 5 heads and 5 tails, because probabilty of 1 toss is 1/2 for tailand 11/2 for a head.
I practice however we might get , say, 6 heads and 4 tails
So experimental probability of e head would be 6/10 and of a tail would be 4/10.
