Answer:
s= -5
Step-by-step explanation:
-12=8+4s
We move all terms to the left:
-12-(8+4s)=0
We add all the numbers together, and all the variables
-(4s+8)-12=0
We get rid of parentheses
-4s-8-12=0
We add all the numbers together, and all the variables
-4s-20=0
We move all terms containing s to the left, all other terms to the right
-4s=20
s=20/-4
s=-5
Answer:
0.1369
(4.732, 5.268)
Step-by-step explanation:
Given that:
Mean, m = 5
Standard deviation, s = 1.5
Error margin, E = 0.5
Sample size, n = 120
Zcritical at 95% = 1.96
Standard Error of the mean (S. E) :
S. E = s /sqrt(n)
S. E = 1.5 / sqrt(120
S.E = 1.5 / 10.954451
S. E = 0.1369306
S. E = 0.1369
Confidence interval (C. I)
Mean ± (Zcritical * S.E)
5 ± (1.96 * 0.1369)
Lower boundary = 5 - 0.268324 = 4.731676
Upper boundary = 5 + 0.268324 = 5.268324
(4.732, 5.268)

Translation is moving a object Y numbers up and X numbers to the side.
When you translate an object it does not change size nor does it rotate. It only changes position on the grid
I hope this helps you :D
