Answer:
The game’s expected value of points earned for a turn is 71.
Step-by-step explanation:
Here we know that:
Points Frequency
50 55
75 32
150 13
Here points earned is a random variable.
We need to find its expected value,
Finding Expected value:
Expected value of a random variable is its mean value. So we will first find the mean value of points earned per turn from the table we are given.
Total number of turns = sum of frequencies
= 55 + 32 + 14 = 100
Total points earned = 50(55) + 75(32) + 150(13)
= 7100
Expected value of points earned for a turn = Mean value of points
= Total points/no. of turns
= 7100/100
= 71

Answer:
Mr. Terry has $36.60 left after these purchases.
Step-by-step explanation:
1. Multiply the amount of glue sticks purchased by their singular cost.
24 x 1.15= 27.6
2. Multiply the amount of pencil packs purchased by their singular cost.
10 x 0.58= 5.8
3. Add the solutions.
27.6+5.8=33.4
4. Subtract 33.4 from 70.
70-33.4=36.60
