The standard deviation is
Given that the sales are normally distributed and that students at a certain school who sell at least 75 magazine subscriptions win a prize then the percent of the fourth grade students receive a prize is mathematically represented as
Generally
So
From the standardized normal distribution table
=>
The percentage of the fourth grade students receive a prize is
k = 0.023 * 100
k = 2.3%
G(x) = x² is the parent square function.
It has its vertex at origin and opens upwards.
The given graph is obtained by shifting the graph of x² 2 units vertically down. This vertically translation can be expressed by subtracting 2 from the parent function.
So,
F(x) = G(x) - 2
F(x) = x² - 2
Thus the correct option is A
Answer:
145 lb
Step-by-step explanation:
416 x 5(oz) = 2080
(Now to convert oz to lb)
