skad [1K]

Answer:

See below

Step-by-step explanation:

  • Initial Principal P₀ = 1000
  • End of first period = 1000 + 1000*0.02/4 = 1005
  • End of second period = 1005 + 1000*0.02/4 = 1010
  • End of third period = 1010 + 1000*0.02/4 = 1015
  • End of fourth period = 1015 + 1000*0.02/4 = 1020

vlabodo [156]

Answer: 1.467

Step-by-step explanation:

Formula of Margin of Error for (n<30):-

E=t_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}

Given : Sample size : n= 22

Level of confidence = 0.90

Significance level : \alpha=1-0.90=0.10

By using the t-distribution table ,

Critical value : t_{n-1, \alpha/2}=t_{21,0.05}= 1.720743

Standard deviation: \sigma=4

Then, we have

E=(1.720743)\dfrac{4}{\sqrt{22}}=1.46745456106\approx1.467

Hence, the margin of error for the confidence interval for the population mean with a 90% confidence level =1.467

Answer:

  D.  86°

Step-by-step explanation:

Points D and F divide the circle into two arcs. The long arc is labeled 274°, and the short arc is the one you're asked to find. You know the total of these two arcs is the full circle, 360°.

  274° + DF = 360°

  DF = 360° -274°

  DF = 86°

__

There are other relationships you can use to find arc DF. One of the simpler ones is ...

  DF and the external angle at E are supplementary:

  DF = 180° -94° = 86°
