How do I solve this question?

Jet001 [13]

Answer:

n=2.5

Step-by-step explanation:

First, write an equation!

n+5n-6+2n+1=15

Now, combine like terms to make things easier.

8n-5=15

Cancel -5 from the left to isolate 5n as a variable.

8n-5+5=15+5

8n=20

Now divide both sides by 8.

8n/8=20/8

n=2.5

Answer:

follows are the solution to this question:

Step-by-step explanation:

Please find the correct question in the attached file:

The formula for calculating the Confidence interval of proportion:

$\to CI=\hat{p} \pm Z_{\frac{\alpha}{2}} \sqrt{\frac{\hat{p}(1-\hat{p})}{n}}\\\\\to \hat{p}=\frac{\text{lower limit +upper limit}}{2}\\$

$=\frac{0.48+0.60}{2}\\\\=\frac{1.08}{2}\\\\=0.54$

The number of learners with access to working at home on a computer:

$= 0.54 \times 300 \\\\=162$

Lower limit =0.48

upper limit = 0.60

$\to margin \ error = \frac{\text{upper limit - lower limit}}{2}\\$

$=\frac{0.60-0.48}{2}\\\\=\frac{0.12}{2}\\\\= 0.06$
