2. The swimming pool can hold 1,000,000 cubic feet of water.
3. Question 1 in powers of 10 is: 105, Question 2 in powers of 10 is: 106
Step-by-step explanation:
Answer:
Mean: 35
Median: 31
Mode: 36.9 (If you round up), 36.8 (If you don't round up)
Step-by-step explanation:
Order the Data: 29, 30, 30, 31, 31, 35, 35, 35, 36
Mean: Average , sum all of your data and divided by how many scores are in your data. (From Math Notes I have)
332/9 = 36.9 (If you round up)
Median: Middle Score (From Math Notes I have)
In this case the Median is 31.
Mode: The score that up most (From Math Notes I have)
In this case the Mode is 35.
Calculating the z scores for each student:
zTara = (52-64 )/8 = -12/8 = -1.5
zJamal = (82-64)/8 = 18/8 = 2.25
zSamuel = (66-64)/8 = 2/8 = 0.25
From the z score table, the probability of Tara's score being greater than -1.5 is 0.0668. Therefore, the percentage is 0.0668*100 = 6.68% which means that around 7% of the students got a better mark than Tara, with 93.32% of the students scoring lower than her.
The probability of Jamal's score being greater than 2.25 is 0.0122, therefore the percentage is 0.0122*100 = 1.22% implying that around 1% of the students got a better mark than Jamal.
The probability of Samuel's score being greater than 0.25 is 0.4013, therefore the percentage is 0.4013*100 = 40.13% which means that around 40% of the students got a better mark than Samuel, with 59.87% of the students scoring lower than him.
