Answer:

C. The data value must be less than the mean.

Step-by-step explanation:

We have been given a statement and we are asked to choose the correct option about our given statement.

Since a z-score tells us that a data value is how many standard deviation away from mean.

To find the z-score for a given data value or raw score, we subtract the mean of data set from the given raw score and divide the result by standard deviation of the data set

If a data value is greater than mean, then it will have a positive z-score. If a data value is smaller than mean, then it will have a negative z-score.

Upon looking at our given choices we can see that option C is the correct choice.

Noah bought 15 baseball cards for $9.00. Each baseball card costs the same amount. How much will 12 baseball cards cost

denis-greek [22]

15 cards = 9$

1 card = (9/15)$

12 cards = 9/15 * 12

= 108/15

= 7.2$

yesterday, 2000 circular jellyfish, each of diameter 2 feet, were lying within a section of ocean floor that measured 120' by 36

Ymorist [56]

The area of one jellyfish is pi r squared or 3.14 x 1 squared (the diameter of the jellyfish is 2 feet so the radius is 1 foot) or essentially 3.14 square feet. 2000 x 3.14 = 6280 square feet. The area of the ocean floor is 120 x 360 feet or 43200 square feet. So 6280/43200 is equal to 0.15 or 15%
