Answer:
Step-by-step explanation:
4. the algebraic representation of the translation is
x+9 and y -4
because for example point (-3, 9) become ( -3+9= 6, 9-4=5)
5.
7 to the left means -7 on the x coordinate and
6 up means +6 on the y coordinate
( x, y ) after translation is ( x-7, y+6)
(12, 3) becomes (12-7= 5, 3+6=9)
(14, 6) becomes (14-7=7, 6+6=12)
(8, 4) becomes(8-7= 1, 4+6=10)
Answer:
an outlier is a number that is at least 2 standard deviations away from the mean for example in the set 1,1,1,1,1,1,1,1,1,7,7,7 would be the outlier

Step-by-step explanation:
For CDF lookups, we used the Excel NORMDIST(x, mean, stdev, TRUE) function. For inverse CDF lookups, we used the NORMINV(x, mean, stdev) function.
Each of these functions works with the area under the curve from -∞ to x, so for cases where we're interested in the upper tail, we subtract the probability from 1, or subtract the x value from twice the mean.
For question 1, we computed the Z values in each case. The NORMDIST function works directly with x, mean, and standard deviation, so does not need the z value.
7/22 you add the denominators toghether and add the numerators.
