The z-score is the number of a data value that represents how many standard deviation is it from the mean. It is calculated from the ratio of the difference of a data value and the population mean and the standard deviation of the data set. Having a z-score of zero would mean that the value is the same as the mean. A z-score that is greater than 1 would mean that the value is x standard deviation greater than the mean. If for a certain data, a z-score of positive 2.5 is calculated, then it means that the data is 2.5 standard deviations away and above from the mean of the whole set. In a normal
6 x 3 is 18. y is equal to 4. 18 minus 4 is 14. The answer is 14.

Answer:
98 degrees
Step-by-step explanation:
57 + 41 is 98
so take 98 from 180 which is 82
then you take 82 from 180 to find x which is 98
Yes I have graphed them and they form a 90 degree angle
