Help with 13,14,15 plsss

Step-by-step explanatio

for 13: A

for 14: Step 1: Recall the definition of an outlier as any value in a data set that is greater than or less than . Step 2: Calculate the IQR, which is the third quartile minus the first quartile, or . ... \displaystyle Q3+1.5*IQR= 89 + 1.5*10 = 104. In the data set, 105 > 104, so it is an outlier.

for 15: not sure at all sorry

13. B) Non-linear

As per its definition, linear means line. If a function is linear, then one can plot it out, and the resulting graph will be a line. This is not the case for the given function, therefore, it is non-linear.

14. A) Yes

An outlier is a data point that does not fit in with the result. It is not in the general region that the rest of the data points fall in. In the given function, the point (0.5, 3) is not in the general region that the rest of the points are in, therefore, it is an outlier.

15. B) Yes, there seems to be two distinct groups of data.

As one can see there appears two be two groups of data. One of them is towards the upper left corner, whereas the other seems to be towards the lower right corner.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

2nd one in the first row is correct
