Question??

Dr. Sox drives through two stoplights on her way to work. The first light is green for 20 seconds out of each minute. The second light is green for 35 seconds out of each minute. What is the probability that Dr. Sox will hit two green lights?

Explanation;

Since this is an AND situation, we MULTIPLY the probabilities.

Answer/Explanation:

First light green:

P

Second light green:

Of course, this is assuming that there is no "green wave" policy, or the two probabilities would not be independent

Anna is following this recipe to make biscuits.
Anna uses 660 mL of syrup.
How many grams of margarine will she need?

Recipe: Makes 24 biscuits
60 g sugar
110 mL syrup
220 g oats
120 g margarine
40 g chocolate​

Answers

Answer:

720 grams

Step-by-step explanation:

660 mL(amount she used) / 110 mL (amount from the recipe) = 6 times

So Anna uses 6 times the amount of syrup from the recipe.

Therefore she also needs 6 times more margarine than it is written in the recipe, which is 120 g * 6 = 720 g

8.) Anthony goes to lunch with his friends. His portion of the bill is $20. He
wants to leave the waitress a 20% tip. How much would he leave for a tip?

Answers

Answer:

23.00

Step-by-step explanation:

If you want to leave a 20% tip, multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total including tip. If you want to leave a 18% tip, multiply the cost by 0.18 to get the tip amount or multiply the cost by 1.18 to get the total including tip.

Answer: Anthony should leave a $4 tip.

Step-by-step explanation:

20% = 0.2

So, multiply $20 × 0.2 = $4
