Answer:
2 and 6 for the circles.
-18 for the square.
Step-by-step explanation:
-3 times a number is -6.
The number is 2.
2 times a number is 12.
The number is 6.
6 times -3.
The number is -18.
Margin of error, e = Z*SD/Sqrt (N), where N = Sample population
Assuming a 95% confidence interval and substituting all the values;
At 95% confidence, Z = 1.96
Therefore,
0.23 = 1.96*1.9/Sqrt (N)
Sqrt (N) = 1.96*1.9/0.23
N = (1.96*1.9/0.23)^2 = 262.16 ≈ 263
Minimum sample size required is 263 students.
Answer:
-18w+2
Step-by-step explanation:
6*-3w=-18w
1/3*6=2
