Hello
<span>y= e^x (x^2 -7x +13)
y' = (</span>e^x)' (x^2 -7x +13)+e^x (x^2 -7x +13)'
y' = e^x(x^2 -7x +13)+e^x (2x-7)
y" = e^x(x^2 -7x +13)+e^x (2)
y"=e^x(x^2 -7x +15)

Three flavors of juice are offered at a school cafeteria The table shows the number of students who purchased each flavor during

Ilya [14]

Answer: A. 0.2

Step-by-step explanation:

Probability for any event = $\dfrac{\text{Favorable outcomes for event}}{\text{Total possible outcomes}}$

Three flavors of juice are offered at a school cafeteria.

The given table:

Orange Grape Cherry

51 30 69

Total juices = 51+30+69 =150

Now, the probability that a student who bought juice chosen at random purchased the grape flavor= $\dfrac{\text{Number of grape juices}}{\text{Total juices}}$

$=\dfrac{30}{150}=0.2$

Hence, the correct option is A.
