This is so blurry, can you take another picture or type the questions out please/
When the vertex is at the origin and the directrix is at y = -2.5, the the parabola must be facing upwards and have a general formula of y = 4a x^2. In this case, a is equal to 2.5 that is, y = 4*2.5 x^2 equal to y = 10 x^2
To solve for the actual value, you need more information, but basically, you need to divide both sides of the equation by 4.
F=132(17.9/100)
f=2362.8/100
f=23.628
f≈23.6 pounds (to nearest tenth of a pound)

Determine the expected value of grams of sugar
This is calculated by multiplying the probability and grams of sugar in each cereal.
The results of the products are then added together
i.e.




Hence;
The expected value of grams of sugar is 9 grams
