Answer:
A, B, and E
Step-by-step explanation:
I hope this helps enjoy your day.
Answer: 4 hours
Step-by-step explanation:
So if Jayne worked twice the amount of susans paycheck, it would be 60/2..so 30 is how much Susan has in her paycheck
Then you would divide both amounts by 7.50 because that’s how much they earn in a hour
J = 60/7.50 = 8 hours
S = 30/7.50 = 4 hours
Susan worked 4 hours
Answer:
The experimental probability is 0.8% more than the theretical probability,
There were approximately 2 more winners than expected
Step-by-step explanation:
Theoretical Probability is given by = 1/8 = 12.5%
Which means that out of 324 players, numbers of winners theoretically are = 0.125 · 324 = 40.5 ≅ 41
To find the probability of experimental data, we have to consider the data recorded by Talia and Yoshi
Recorded winners = 43
Total players = 324
Experimental Probability = Numbers of winners/ Total Number of players · 100
Experimental Probability = 43/321 · 100 = 13.3%
The difference between Experimental and Theoretical Probability is = 13.3% - 12.5% = 0.8%
Difference of Winners ≅ 43 - 40.5 ≅ 2
So sorry this is late! Hopefully this can still be useful in some way.
A: 13 students took the test. count how many dots there are, and that your answer!
B: The median score is 60. We can find this by ordering all the scores in order from least to greatest, and finding which is in the middle. In this question, its 20, 20, 20, 20, 40, 50, 60, 60, 60, 80, 80, 80, 90
C: There are 7 students that scored at least a 60. All we have to do is count how many dots there are at 60 or above!
Again, sorry for being late, but hope this helped :)
