Answer:
<u>15 outfits</u>
Step-by-step explanation:
<u>Given</u>
- one black
- one pink
- one orange
- one w/ flowers
- one w/ polka dots
- one gray
- one white
- one w/ "I love New York!"
<u>Probability : No. of outfits</u>
- There are 3 elements in set A (skirts) and 5 elements in set B (blouses)
- Therefore possible outfits = A x B = <u>15 outfits</u>
<u></u>
<u>P.S. Sorry I couldn't create the probability table.</u>
Answer:
swimmer b swims 100 yards. approximately how many more feet did swimmer a swim than swimmer b? 2.
Step-by-step explanation:
It would be D, because to be a function, a set of ordered pairs cannot have the same x value. The y value can be the same though.
(5,6), (8,6), (9,6)
As you can see, all of the x values are different, so it is a function.
Answer:
Step-by-step explanation:
26% is (26-20)/(50-20) = 6/30 = 1/5 of the way between 20% and 50%. That means 1/5 of the solution is 50% acid.
50% acid: 1/5 · 100 mL = 20 mL
20% acid: 100 mL -20 mL = 80 mL
Delbert must mix 80 mL of 20% acid and 20 mL of 50% acid.
_____
Maybe you'd like to see an equation. Let x represent the amount of 50% acid required. Then 100-x is the amount of 20% acid needed. The amount of acid in the mix is ...
0.50(x) +0.20(100 -x) = 0.26(100)
(0.50 -0.20)x = (0.26 -0.20)100 . . . . subtract 0.20(100)
x = (0.26 -0.20)/(0.50 -0.20)×100 = 20
This last expression should look a lot like the one we started with in this answer. It shows you how you can almost write down the answer to mixture problems without a lot of work.
