72 green marbles
Step-by-step explanation:
45 divided by 5 is 9 so 8 times 9 is 72
No this is not a function. A function is a set of inputs, x-values with a single output. Since 13 has two outputs, 4, and -4, this is not a function.

%
Step-by-step explanation:
Answer
given,
WHOLESALE SALES
Number Sold 2,000 5,000 10,000 20,000
Probability 0.1 0.3 0.4 0.2
RETAIL SALES
Number Sold 600 1,000 1,500
Probability 0.4 0.5 0.1
Wholesale Sold
= 2000 (0.10) + 5000 (0.3) + 10000 (0.4) + 20000 (0.2)
= 9700
Cost = 9700 x $20
= $ 194,000
Retail Sale
= 600 (0.4) + 1000 (0.5) + 1500 (0.1)
= 890
Cost = 890 x $30
= $ 26,700
Profit this year
= $ 194,000 + $ 26,700
= $ 220,700
