Answer:
0.08
1/4
0.3
1.3
40%
85%
Step-by-step explanation:
Try converting all of these numbers to decimal. 40% would be 0.4, 1/4 would be 0.25, 1/3 would be 0.3 repeating, and 85% would be 0.85. From there, reordering the numbers is pretty easy.
Answer:
700$
Step-by-step explanation:
If all the seats cost tge same and each member takes a seat each game so we can say:
7×4=28
5×4=20
28x+20x=1200
48x=1200
x=25(seat price)
28×25=700
20×25=500

The mean grade on the quiz was 88.
<u>Step-by-step explanation:</u>
We need to find the mean grade of the quiz using the information given.
The mean also known as the average is defined as the sum of data entries in a set divided by the number of entries in the data set.
The standard deviation gives the amount of variation or dispersion of data values present in a data set.
The given data are,
- The standard deviation of the quiz, SD = 3.
- The score 94 is exactly 2 standard deviations above the mean.
The above sentence represents that 94 is above the mean with 2 standard deviations.
⇒ 94 = Mean + 2 standard deviations.
We know the value for standard deviation. So substitute SD= 3 in the expression provided.
⇒ 94 = Mean + (2×3)
⇒ 94 = Mean + 6
To find mean, subtract 6 on both sides.
⇒ 94 -6 = Mean
⇒ Mean = 88
Therefore, the mean grade on the quiz was 88.
