B. 2/9
You add up how many marbles there are. in this case there is 10. 3 out of those are blue. so you start out with the probability being 3/10. you take 1 marble out, making the total 9 now. now look at the color. you started with 2 red, 3 blue, and 5 yellow. you pulled out a blue, didnt put it back, so now there are 2 blue marbles left out of 9 marbles. there probability is now 2/9. hope i helped you.

AfilCa [17]

Answer:

p = 250 - 15(w)

Step-by-step explanation:

Original amount: 250

No of weeks to return money: w

Amount to pay each week: 15

Amount that he has paid back: 15 × w (When we subtract this term from the total we will get the answer)

So after w weeks he owes his parents :

Sam's total expenses last month were $1840. What was his total variable cost for last

likoan [24]

Answer:

$1500

Step-by-step explanation:

It is given that

Rent = $100

Groceries and drinks = $1000

Insurance premiums = $10

Loan interest payment =$30

Clothes = $200

Utilities = $300

Home security fee = $200

Fixed cost are costs that does not vary and variable cost are costs that vary with goods and services.

In the given problem, rent , insurance premiums, loans interest payment ad home security fee are fixed cost.

Groceries and drinks, clothes and utilities are variable cost.

So, total variable cost for last month is

$\text{Total variable cost}=\$1000+\$200+\$300=\$1500$

Therefore, total variable cost for last month is $1500.
