Find the area of the shaped region

Answer:

Assuming π is represented by 3.14, the correct answer is $50.24m^2$ .

Step-by-step explanation:

Because the question is asking for the area of the shaded region, you can ignore the non-shaded versions of the diagram. The formula of finding the area of a circle is $\pi r^2$ , where r is the radius of the circle. Since the radius of the shaded circle is $4m$ , you can infer that the area of the shaded region would be $4^2 * 3.14$ = $16*3.14$ = $50.24m^2$ .

Answer:

107

Step-by-step explanation:

Given that after a ham is cured it may be smoked to add flavor or to ensure it lasts longer.

Let X be the smoking time . Then X is N(mu, 8)

a) The sample is drawn at random

b) The sample represents the population

c) Sample size is sufficient to represent the population

b)For 99% conf interval z critical is taken since population std dev is given

Z critical = 2.58

Hence confi interval = $(\mu+/- 2.58*\frac{\sigma}{\sqrt{n} } \\=(\mu +/- 2.58\frac{8}{6} )\\= (\mu -3.44, \mu+3.44)$

c) As sample sizes are large and samples are randomly drawn, we can be 99% confident that sample mean falls within this interval

d) If margin of error is only 2, then we must have

$2.58*\frac{8}{\sqrt{n} } =2\\10.32=\sqrt{n} \\n=106.50\\n~107$

Select the correct answer.

Sonja [21]

Answer:

B) 5 + 17i is your answer.

Step-by-step explanation:

In order to write this equation as a complex number in standard form, you must first simplify each term.

<em>Apple the distributive property.</em>

21 - 4i - 1 * 16 - (7i) + 28i

<em>Multiply -1 by 16.</em>

21 - 4i -16 - (7i) + 28i

<em>Multiply 7 by -1.</em>

21 - 4i - 16 - 7i + 28i

<em>Now simplify by adding terms :)</em>

<em>Subtract 16 from 21.</em>

5 - 4i - 7i + 28i

<em>Subtract 7i from -4i.</em>

5 - 11i + 28i

<em>Add -11i and 28i.</em>

= 5 + 17i
