Why does the margin of error increase as the level of confidence increases? Choose the correct answer below. A. The margin of e

Debora [2.8K]

Answer:

The margin of error increases as the level of confidence increases because the larger the expected proportion of intervals that will contain the parameter, the larger the margin error.

Step-by-step explanation:

Margin of Error is a statistical measure of random sampling error insurvey results.

Level of confidence reflects percentage range around sample mean, that can be expected to contain population actual parameter.

High level of confidence means larger range band of confidence interval, supposed to contain the population parameter. This further implies high expected variation between sample statistic & actual parameter i.e Margin Error increases.

Determine which equations have the same solution set as StartFraction 2 Over 3 EndFraction minus x plus StartFraction 1 Over 6 E

gtnhenbr [62]

The correct question as understood from the statement is:

Determine which equations have the same solution set as 2/3 – x + 1/6 = 6x by recognizing properties, rather than solving. Check all that apply.

a) 4 - 6x + 1 = 36x

b) 5/6 - x = 6x

c) 4 - x + 1 = 6x

d) 5/6 + x = 6x

e) 5 = 30x

f) 5 = 42x

Answer:

Options: a, b and f

Step-by-step explanation:

The given equation is:

$\frac{2}{3}-x+\frac{1}{6}=6x$

Adding x to both sides, we get:

$\frac{2}{3}+\frac{1}{6}=7x\\\\ \frac{4}{6}+\frac{1}{6}=7x\\\\ \frac{5}{6}=7x\\\\ 5=42x\\\\ x=\frac{5}{42}$

Option a) 4 - 6x + 1 = 36x

Moving 6x to the right hand side of the equation and simplifying the answer, would give us 5 = 42x, which is the same as the second last equation in above simplification. Thus this equation has the same roots.

Option b) 5/6 - x = 6x

Moving x to other side will give us the same equation as we got in 3rd last step of the above simplification. Thus this equation has the same roots.

Option c) 4 - x + 1 = 6x

Moving x to other side, and simplifying the result gives us an equation which does not match with the equations in above simplifications. So, this equation does not have the same root.

Option d) 5/6 + x = 6x

Moving x to other side, and simplifying the result gives us an equation which does not match with the equations in above simplifications. So, this equation does not have the same root.

Option e) 5 = 30x

This does not match with the second last step of the above simplification. So, this equation does not have the same root.

Option f) 5 = 42x

This equation matches with the second last step of the above simplification. Thus this equation has the same roots.

How do I subtract 6 5/12 - 2 2/3=

Marina86 [1]

First you make them fractions that have the same denominator. 12 can be the denominator, because 6 5/12 already has that denominator and to get 2 2/3 to have a denominator of 12, you multiply the numerator and denominator by 4 (3•4=12, but you have to do the same thing to the top and bottom of the fraction). You then have the equation
6 5/12- 2 8/12. Since you cant subtract 8/12 from 5/12, you turn the numbers into improper fractions, which would be
77/12 - 32/12. You subtract them and get 45/12. You then have to simplify it again, 12 can go into 45, 3 times and you would have 3 and 9/12. 9/12 can be simplified down to 3/4. So the answer would be 3 3/4.
