Answer:

n = 5, 6, 7

Step-by-step explanation:

Change both fractions into fractions with denominator 16 ( LCM of 4 and 2 )

$\frac{4(1)}{4(4)}$ and $\frac{8(1)}{8(2)}$ , that is

$\frac{4}{16}$ and $\frac{8}{16}$

The fractions between with denominator of 16 are

$\frac{5}{16}$ , $\frac{6}{16}$ , $\frac{7}{16}$

with values of n = 5, 6, 7

Select the equations that are equivalent to the equation y – 2 = 3(x + 6). Select all that apply.

amm1812

The correct answer for the exercise shown above is the first option and the las option, which are:

<span>y = 3x + 20
3x - y = -20
</span>
The explanation is shown below:

1. You have the folllowing expression given in the problem above:

y-2=3(x+6)

2. If you solve it for y, you have:

y-2=3x+18
y=3x+18+2
y=3x+20

3. And if you move the variables to the left member, you have:

3x-y=-20

Therefore, as you can see, the correct answer are the options mentioned above.

In a recent study of statistics students, a random sample of students were asked to provide the number of hours per week they sp

Airida [17]

Answer:

$ME=\frac{Upper-Lower}{2}= \frac{8.15-6.55}{2}= 0.80$

Step-by-step explanation:

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

$\bar X$ represent the sample mean for the sample

$\mu$ population mean (variable of interest)

s represent the sample standard deviation

n represent the sample size

Solution to the problem

The confidence interval for the mean is given by the following formula:

$\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}$ (1)

For this case the confidence interval is given by (6.55,8.15). And we can estimate the margin of error with this formula since the confidence interval is symmetrical:

$ME=\frac{Upper-Lower}{2}= \frac{8.15-6.55}{2}= 0.80$
