Answer:
46
Step-by-step explanation:
We are given that a class's test scores are normally distributed with an average score of 60.
We know that the curve of a normal distribution is symmetric about its mean.
60-14=46
60+14=74
Hence, the point 46 lies to the left of the mean and 74 lies to the right of the mean, and the two points have the same function value.
Your question answers itself. You solve by graphing.
I like to subtract one side of the equation from the other, so the solutions are where the graph crosses the x-axis (the resulting function value is zero).
It can be useful to find the "turning point" of each absolute value expression (where its value is zero) and graph that and some points on either side.
Answer:
C
Step-by-step explanation:
Answer:
c = 15 meters
Step-by-step explanation:
This is solveable using the Pythagorean Theorem,
let's say a = 9 and b = 12,
a^2 + b^2 = c^2, so
9^2 + 12^2 = 225 then,
sqrt(225) = 15, so c = 15 m
