A. The scores in order are: 10, 12, 13, 14, 14, 16, 18, 23, 24, 26. The range is 26 - 10 = 16. The mean is the sum divided by 10, which is 17. The median is between 14 & 16, which is 15. The mode is 14, since it is repeated twice.
B. The variance is calculated by subtracting each score from the mean, squaring, and adding all such squares. Then divide by the number of terms (10) to get 27.6 Take the square root to get the standard deviation, which is 5.25.
C. This is for a population, since these are all 10 games that Jason played. (If it were a sample, we would divide by 9 only)
D. The mean of 17 is higher than the median of 15 and the mode of 14. This implies a left-skewed distribution. However, the SD of 5.25 is quite high relative to the mean of 17, so the distribution is not that clearly defined yet (more data points would make it clearer).
A good display to use for his situation is a bar chart. It will show the number of students that like each flavor so they are easy to compare.
Answer:
0.05
Step-by-step explanation:
I turned the fractions into decimals. to do that your do exactly as it tells you!
4 divided by 5 = 0.8
so she has 0.8 ounces of juice (That not alot lol I would not be satisfied) now for how much she drank...
3 divided by 4 =0.75
0.80 - 0.75 = 0.05
She drank 0.05 ounces
Hope this helped! Please mark as brainliest! Thanks! If you need me to turn 0.05 in a fraction i can do that.
X^2+4+10=0
x=(-4(+/-)root16-40)/2, so we now know that the zeros are imaginary, because you can't square root a negative number and 16-40 is -24
so the two roots are…
-2+iroot6 and -2-iroot6
