Answer:
- 3/4
- 4/13
- 7/26
- 2/13
- 5.52
Step-by-step explanation:
<u>(a)</u>
- Probability (A heart or a black card) = 13 + 26 / 52
- Probability (A heart or a black card) = 39/52
- Probability (A heart or a black card) = 3/4
<u>(b)</u>
- Probability (A heart or a jack) = 13 + 3 / 52
- Probability (A heart or a jack) = 16/52
- Probability (A heart or a jack) = 4/13
<u>(c)</u>
- Probability (A heart and the ace of clubs) = 13 + 1 / 52
- Probability (A heart and the ace of clubs) = 14/52
- Probability (A heart and the ace of clubs) = 7/26
<u>(d)</u>
- Probability (A 9 or a jack) = 4 + 4 / 52
- Probability (A 9 or a jack) = 8/52
- Probability (A 9 or a jack) = 2/13
<u>(e)</u>
- Probability (The 9 of hearts or a jack) = 1 + 4 / 52
- Probability (The 9 of hearts or a jack) = 5/52
Answer:
50y
Step-by-step explanation:
This is because 150 minus 100 equals 50
Also because they have the same "y" they can be subtracted easily.
Hey!
Hope this helps...

When looking at this graph we see 2 things:
(1) How they made the graph, looks awful, anyway...
(2) They practically give you the answer...
When finding an answer to a question like this, you want to use a formula (like this):
A = t * p (where A is the amount of people, t is total amount of people, and p is percent of people / 100)...
So... we fill in the givens...
We know t = 400, and (by looking at the graph) we see that p is around 0.10 and 0.15. So for our sake we'll make p = 0.13 (about halfway)...
A = 400 * 0.13
A ~ 52
The answer is: About 52 people bought 20 items...
And because we got 52, and 52 is close to 54...
<em>The Answer: B.) 54</em>
I don’t understand u sorry ;-;
