Answer:
D. The distance from the mean to an inflection point
Step-by-step explanation:
We rarely encounter the actual formula for the normal PDF. It is ...
In fact, the inflection points are at x = ±1, where the curve changes from being concave downward to concave upward.
So, one standard deviation is the distance from the mean to an inflection point.
The answer is 18
Working out:
1 1/2 x 4 =6
6 x 3=18
Answer:
C / 20
Step-by-step explanation:
Number of students in the baking club = 10
Each student made 2 chocolate cakes
Total cakes = number of students × number of cakes per student
= 10 × 2
= 20
Total cups of flour used by 10 students = C cups
Amount of flour for one cake = Total cups of flour / Total cakes
= C / 20
The expression that represents the amount of flour for one cake = C / 20
