Your answer should be 71. :)
Answer:
the margin of error is 0.05
Step-by-step explanation:
Margin of error = confidence interval ÷ 2
MOE = CI ÷ 2
Confidence interval CI = 0.2 - 0.1 = 0.1
MOE = CI ÷ 2 = 0.1 ÷ 2 = 0.05
the margin of error is 0.05
Substitute x = 3 in any given equations. I will do in y = - x + 1
Therefore the answer is (3,-2)
Answer: 4/5
Step-by-step explanation:
1. you need to know the formula which is m = y2-y1/x2-x1
2. you plug in the numbers which would be 9-5/3-(-2)
3. you get your answer as 4/5
4. the answer is 4/5
Answer: - 49
Step-by-step explanation:
f(x) = -2x - 1
g(x) = 
- 1
fg(x) = f ( - 1) , we just put in the value of g(x) , the next thing is to substitute - 1 for the value of x in f(x) , that is
fg(x) = -2( - 1) - 1
fg(x) = -2 + 2 - 1
fg(x) = -2 + 1
Therefore : fg(-5) means we will substitute -5 for x in fg(x) , that is
fg(-5) = -2 (
+ 1
fg(-5) = -2(25) + 1
fg(-5) = -50 + 1
fg(-5) = -49
