Answer:
95%
Step-by-step explanation:
We have that:
The number of potato chips in a bad is normally distributed with a mean of 75 and a standard deviation of 5.
We want to use the empirical rule to solve this:
We know that:
65=75-2(5)
That means
Also, 85=75+2(5)
According to the the empirical rule approximately 95% of the distribution is within 2 standard deviation of the mean
Y = -2x - 3
When I put this into y2-y1/x2-x1 (equation to find slope) I did the coordinate pairs (3,-9) and (4,-11). When you plug it in it’s -11+9/4-3. This gets you -2/1, which is -2. That’s your slope. Then, in order to get the y-intercept, you can use any of those pairs. I did -9 = 3(-2) + b. -9=-6 + b and in the end this gets you -3 = b. So the full equation is y = -2x - 3.
