2 answers:

8 0

The fraction that has the same value as 7/8 is 21/24.
They have the same value because when 21/24 is reduced, it equals 7/8.
Here is how you would reduce 21/24:
21/24 divide both the numerator and denominator by 3.
21 divided by 3 = 7
24 divided by 3 = 8

Can you please help me find the value of x and y while l is parallel to m.

12345 [234]

Answer-

The values of x and y are 13 and 24, respectively.

Solution-

From the attachment, l and m are parallel lines and

$\Rightarrow (5x-8)+(4y+27)=180$

$\Rightarrow 5x+4y=161$ ---------------------1

As, when a traversal line intersects two parallel lines, same-side interior angles are supplementary, or they add up to 180 degrees.

$\Rightarrow (7x-31)+63=4y+27$

$\Rightarrow 7x-4y=-5$ ---------------------2

As, an exterior angle is equal to the sum of the opposite interior angles.

Adding equation 1 and 2, we get,

$\Rightarrow 5x+4y+7x-4y=161-5$

$\Rightarrow 12x=156$

$\Rightarrow x=13$

Putting the value of x in equation 1, we get

$\Rightarrow y=24$

Use the given information to find the minimum sample size required to estimate an unknown population mean μ.

larisa86 [58]

Answer:

The number of business students that must be randomly selected to estimate the mean monthly earnings of business students at one college is 64.

Step-by-step explanation:

The (1 - α) % confidence interval for population mean is:

$CI=\bar x\pm z_{\alpha/2}\ \frac{\sigma}{\sqrt{n}}$

The margin of error for this interval is:

$MOE= z_{\alpha/2}\ \frac{\sigma}{\sqrt{n}}$

The information provided is:

σ = $569

MOE = $140

Confidence level = 95%

α = 5%

Compute the critical value of z for α = 5% as follows:

$z_{\alpha/2}=z_{0.05/2}=z_{0.025}=1.96$

*Use a z-table.

Compute the sample size required as follows:

$MOE= z_{\alpha/2}\ \frac{\sigma}{\sqrt{n}}$

$n=[\frac{z_{\alpha/2}\times \sigma}{MOE}]^{2}$

$=[\frac{1.96\times 569}{140}]^{2}\\\\=63.457156\\\\\approx 64$

Thus, the number of business students that must be randomly selected to estimate the mean monthly earnings of business students at one college is 64.

What is negative 9 plus 16/7

jekas [21]

Step-by-step explanation:

-9 + 16/7 = ?

First, find out what 16/7 would make in decimal form, by dividing 16 by 7 (Use a calculator if needed)

16 / 7 = 2.3 (In estimation)

So, now you have ' -9 + 2.3 '

= -6.7
