Simon has a bag containing 8 red marbles, 9 yellow marbles, and 11 green marbles.

1 answer:

3 0

Here is a hint:

The chance of taking a red marble out of the bag would be 8/28=4/17. The probability of taking out ANOTHER red marble would be 7/27 because if you took a marble out the total would be one less, 28-1=27. And if it is red, than 8-1=7. Using this it will be easier to find the answer to your question. Good luck.

notsponge [240]

Answer:

D. $f(t)=300+0.20t$

Step-by-step explanation:

We have been given that Mikayla is a waitress who makes a guaranteed $50 per day.

Since Miklaya works 6 days per week, so the guaranteed income for one week would be $\$50\times 6=\$300$

We are also told that she gets tips of 20% of all her weekly customer receipts, t. So amount earned from tips would be 20% of t, that is $\frac{20}{100}t=0.20t$ .
