Hi there,
I’m attaching the same image with more information on the graph.
The 4th mark (the middle dashed line) is marking the mean (70).
The 3rd and the 5th are marking the mean less/plus 1 deviation.
So, 70.5 is the 5th mark.
Taking this into account:
The probability of selecting a container that has less than 70.5 is 0.1% + 2.2% +13.6% 34.1% + 34.1% = 84.1%
The probability of choosing more than 70,5 = 13.6% + 2.2% +0.1% = 15.9%
Good Luck!

Step-by-step explanation:
First find the slope of the line containing points (5,4) and (-7,9). To find the slope use the formula . Putting those values in, you have
Simplify
Then, to find the slope of the line perpendicular to that, find the negative reciprocal.
