Please help! Thanks!: If a 95% confidence interval was being calculated using the following expression:
3.2 ± 1.96 ⋅ 1.1
What would be the margin of error for this confidence interval?
If you can please give an explanation on how to solve?
The confidence interval can be calculated from the margin of error, and vice versa,
The margin of error of the confidence interval is 2.156
The confidence interval is given as:
[tex]\mathbf{CI = 3.2 \pm 1.96 \cdot 1.1}[/tex]
The formula of confidence interval is:
[tex]\mathbf{CI = \bar x\pm E}[/tex]
Where E represents the margin of error.
So, by comparison:
[tex]\mathbf{E = 1.96 \cdot 1.1}[/tex]
Multiply
[tex]\mathbf{E = 2.156}[/tex]
Hence, the margin of error of the confidence interval is 2.156

Answer:
first off theres two ways of doing it the equation is more fun though
14.5 = x + 4.5
14.5 = x(5) -4.5
-4.5
10 = 5x
divide by 5
you get
2x or $2
other way was to just -4.5 and divide by 5 but thats no fun

Answer:
1/98
Step-by-step explanation:
Step 1: Translate statement into equation.
[tex]\frac{1}{7}/x = 14[/tex] [tex]\frac{1}{7x}=14[/tex]Step 2: Multiply both sides by 7x.
[tex]\frac{1}{7x} * 7x = 14 * 7x[/tex] [tex]1 = 98x[/tex]Step 3: Divide both sides by 98.
[tex]\frac{1}{98} =\frac{98x}{98}[/tex] [tex]x = \frac{1}{98}[/tex]Step 4: Check if solution is correct.
[tex]\frac{1}{7}/\frac{1}{98}[/tex] [tex]\frac{1}{7}*98[/tex] [tex]14[/tex]Therefore, the answer is 1/98.

What is 23=5-2/3m ??????
Answer:
Step-by-step explanation:
if it's
23 = 5 - (2/3)m
18 = (-2/3)m
m = 18(-3/2)
m = -27
if it's
23 = 5 - 2/(3m)
18 = -2/(3m)
18(3m) = -2
54m = - 2
m = -2/54
m = - 1/27

Answer:
∠ACD = 33.5°
Step-by-step explanation:
The arc length will be twice ∠ ABD,
∠ABD will equal ∠ACD because they subtend the same arc length.
3x + 7 = 2(2x - 6.5)
3x + 7 = 4x - 13
x = 20
∠ABD = (2(20) - 6.5) = 33.5

Answer:
[tex]a)55[/tex]
b) 18
Step-by-step explanation:
→ Set up an for part a
[tex]\frac{80x}{100} =44[/tex]
→ Multiply both sides by 100
[tex]80x=4400[/tex]
→ Divide both sides by 80
[tex]x = 55[/tex]
