35r+10+20p
you would multiply by 5 to all the numbers in the parantheses
The answers checked for #1, #2, #4, and #5 are correct.
In #3, the constant factor is -3 . So the absolute value of
each term is 3 times the absolute value of the previous one,
AND the signs alternate.
5. complementary angles = 90°
90 - 40 = 50
50°
6. supplementary angles = 180°
180 - 40 = 140
140°
The z-statistic can be calculated as the difference in the population mean and sample mean divided by the standard error. The standard error can be calculated as the standard deviation divided by square root of sample size. The standard error:
SE = 12/ sqrt(20) = 2.68
The z-statistic: (195 -208) 2.68 = -4.86
