Answer:
1128
Step-by-step explanation:
hello :
this aritmetic seq when the first term is A1 =-16
the common diference is d= 10-(-3)=(-3)-(-16)=13
the nth term is : An =A1+(n-1)d =-16+13(n-1) =13n-29
the 89th term when : n=89 A89 = 13(89)-29 = 1128

x =
Answer:
A <u>z-score</u> indicates how far an individual raw score falls from the mean of a distribution; the <u>standard deviation</u> indicates how the scores in general scatter around the mean.
Step-by-step explanation:
We have been given an incomplete statement. We are supposed to complete the given statement.
We know that z-score of a data set indicates that a sample score or raw score is how many standard deviation away from the mean. Z-score indicates the distance of a raw score is above or below mean in units.
Therefore, the correct word for 1st blank would be "z-score".
We also know that standard deviation represents the variation of a data set. It tells that data points of a data set are how much close or away from mean of the data set.
Therefore, the correct word for 2nd blank would be "standard deviation".
