Answer:
We have a1 = 27 and r = 3 (because 27:9 = 3; 9:3 = 3; 3:3 = 1);
Then s = 27 / (1 - 3) ;
Finally, s = - 27 / 2;
Step-by-step explanation:
Answer:
(1.5 ,1)
Step-by-step explanation:
f(x) = g(x) where the two graphs intersect
x=1.5 and y = 1
(1.5 ,1)
Answer:
21
Step-by-step explanation:
25-4=21
All of the questions are 25, he hasn't answered 4, so fron 25 you remove 4, and the answer is 21.
The measured data is
x=[10.56, 9.52, 9.73, 9.80, 9.78, 10.91].
Calculate the mean.
m = (10.56+9.52+9.73+9.80+9.78+10.91)/6 = 10.05
Calculate the deviations from the mean.
k = x - m
= [0.51, -0.53, -0.32, -0.25, -0.27, 0.86]
Calculate the absolute deviation from the mean.
