<span>To find the expected recorded score, we need to find the sum of (x + y) times P(x +y), which gives us 14.4. The expected recorded score goes through the same process, but we only use the maximum scores and this gives us 9.75</span>
Answer:
Please see attached graph for answer.
Step-by-step explanation:
We can easily solve this question by plotting the graphs of both functions in a graphing calculator.
We have
y = √(-4x-36)
y = √(-4(x+9))
g = √(x)
We can see that the function y corresponds to a mirrored version of function g. Each x is scaled by a factor of -4, and shifted to the left in 9 units
If you would like to solve 2/3 * m - 1 1/6 + 5/6 * m - 1 1/3, you can calculate this using the following steps:
<span>2/3 * m - 1 1/6 + 5/6 * m - 1 1/3 = 4/6 * m + 5/6 * m - 7/6 - 4/3 = 9/6 * m - 7/6 - 8/6 = 1 3/6 * m - 15/6 = 1 1/2 * m - 2 3/6 = 1 1/2 * m - 2 1/2
</span>
The correct result would be c. <span>1 1/2 * m - 2 1/2.</span>
