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!
Looking at the equation, you could see that it is in vertex form. Vertex form looks like this: y=a(x-h)^2+k where a is the slope to find the first point away from the origin and (h,k) is the vertex. So, the vertex is (3,-1). The first point away from the origin is up two, over one, so the slope is 2. This means that a is 2. One way you could check this is by putting 2 in for a. If you put it into standard form, it would be 2x^2-12x+17. To find the x in the vertex when the equation is in standard form we use -b/2a. So it would give us 3 for x. If we put in 3 for x, we get -1 for y, so the vertex is (3,-1). This means that a is 2. Sorry for this lengthy answer, hope it helps.

Answer: k = 18
Step-by-step explanation:
1) Move all terms to the left:
3k/6-(9)=0
2) Multiply all the terms by the denominator
3k-9*6=0
3) Add all the numbers together, and all the variables
3k-54=0
4) Move all terms containing k to the left, all other terms to the right
3k=54
k=54/3
k=18
