At 11:45 A.M. Jason glanced at the clock. His doctor's appointment was in 2 ½ hours. At what time was his appointment
Dafna1 [17]

Answer:

14 : 15 or 2 : 15 pm

Step-by-step explanation:

Time of the appointment = 11: 45 +  2 ½ hours

Jason's appointment is in  2 ½ hours. His appointment is in 2 hours + 1/2 of an hour

1/2 of an hour = 1/2 x 60 = 30 minutes

Remember that 60 minutes make one hour

Time of the appointment = 11:45 + 2:30

 11 : 45

+ <u>2 : 30 </u>

 13 :  75

we would have to adjust the time derived from the addition because the maximum minutes that exist is 60

To adjust, remove 60 minutes from the minutes and add it to the hour

this gives 14 : 15 or 2 : 15 pm

Galina-37 [17]

Answer:

The answer is "16, 43, and 96".

Step-by-step explanation:

Given:

\sigma = 0.20\\\\c = 95\% = 0.95\\\\\therefore \alpha = 1- c = 1- 0.95 = 0.05\\\\\therefore  \frac{\alpha}{2} = 0.025\\\\

Using Z table:

\therefore Z_{\frac{\alpha}{2}} = 1.96\\\\

For point a:

E = 0.10\\\\n=(\frac{Z_{\frac{\alpha}{2} \times \sigma}}{E})^2

    = (\frac{(1.96\times 0.20)}{0.10})^2\\\\=  15.3664 \approx  16

so, The Sample size (n) = 16

For point b:

E = 0.06\\\\n=(\frac{Z_{\frac{\alpha}{2} \times \sigma}}{E})^2

   = (\frac{(1.96\times 0.20)}{0.06})^2\\\\=  42.6844444444\approx  43

For point c:

E = 0.04\\\\n=(\frac{Z_{\frac{\alpha}{2} \times \sigma}}{E})^2

    = (\frac{(1.96\times 0.20)}{0.04})^2\\\\=  96.04\approx  96
