What is the area of shaded section of the circle?

bazaltina [42]

Answer:

≈ 565.5 units²

Step-by-step explanation:

The area (A) of the shaded sector = area of circle × fraction of circle

A = πr² × $\frac{162}{360}$ ← r is the radius

= π × 20² × $\frac{162}{360}$

= 400π × 0.45 ≈ 565.5 units²

Which statements are correct interpretations of this graph?

kupik [55]

Answer:

B. 3 pages are edited every five minutes

D. 6/10 of a page is edited per minute

Step by step:

Three pages are done at an interval of five minutes.

Six tenths of a page is done every minute

0.6 * 5 = 3 per five minutes

The other statements are false.

12/3 = 4, four done every minute, really?

5 pages are edited every three minutes.

This would disprove statement B.

And does not align with the graph.

Hope this helps.

Since sample size is > 40, we use the z-score in calculating for the confidence interval.

The formula is given as:

Confidence Interval = X ± z * σ / sqrt (n)

Where,

X = mean = $50,340

z = z-score which is taken from standard distribution tables at 90% confidence interval = 1.645

σ = standard deviation = $10,780

n = sample size = 45

Substituting to the equation:

Confidence Interval = 50,340 ± 1.645 * 10,780 / sqrt (45)

Confidence Interval = 50,340 ± 1,607

Confidence Interval = $48,733 to $51,947

<span>Therefore the salary range of the personnel is $48,733 to $51,947.</span>
