The area of the given figure 156.75 sq cm.

Step-by-step explanation:

Here,

The figure is a trapezium.

In this trapezium

a = 22 cm

b = 6.5 cm

A and b are the length of two parallel sides.

Height (h) = 5.5 cm

To find the area of the figure which is consists of two trapezium

Formula

Area of the trapezium = $\frac{1}{2} (a+b)h$

Now,

The area of one trapezium = $\frac{1}{2} (22+6.5)X5.5$ sq cm

= 78.375 sq cm

So,

The area of the figure = 78.375×2 sq cm = 156.75 sq cm

A nurse at a local hospital is interested in estimating the birth weight of infants. how large a sample must she select if she d

enyata [817]

For large sample confidence intervals about the mean you have:

xBar ± z * sx / sqrt(n)

where xBar is the sample mean z is the zscore for having α% of the data in the tails, i.e., P( |Z| > z) = α sx is the sample standard deviation n is the sample size

We need only to concern ourselves with the error term of the CI, In order to find the sample size needed for a confidence interval of a given size.

z * sx / sqrt(n) = width.

so the z-score for the confidence interval of .98 is the value of z such that 0.01 is in each tail of the distribution. z = 2.326348

The equation we need to solve is:
z * sx / sqrt(n) = width
n = (z * sx / width) ^ 2.
n = ( 2.326348 * 6 / 3 ) ^ 2
n = 21.64758

Since n must be integer valued we need to take the ceiling of this solution.
n = 22

Company XYZ closed at $46.07 per share with a P/E ratio of 16.66. Answer the following questions.

Andrew [12]

The amount of earnings per share is $2.77.

<h3>Earnings per share</h3>

a. Earnings per share = price per share / (P/E) ratio

Earnings per share = $46.07 / 16.66

Earnings per share= $2.77

B. Overpriced or underpriced stock

At P/E ratio = 12

Earnings per share = $46.07 / 12

Earnings per share = $3.84

Earning yield = ( Earning per share / market value )× 100

Earning yield = (3.84 / $46.07 ) × 100

Earning yield = 8.34%

At P/E ratio = 13

Earnings per share = $46.07 / 13

Earnings per share = $3.54

Earning Yield= (3.54 / 46.07 ) × 100

Earning Yield= 7.68%

At P/E ratio = 14

Earnings per share = $46.07 / 14

Earnings per share = $ 3.3

Earnings yield= ( 3.3 / 46.07 )×100

Earnings yield= 7.16%

Average of earning yield given P/E ratio is 12-14

Average of earning yield= ( 8.34 + 7.68 + 7.16 ) / 3

Average of earning yield= 7.73%

Earning yield = ( Earning per share / market value ) × 100

Earning yield= ( 2.77 / 46.07 ) ×100

Earning yield = 6.01%

Hence, Based on the above the stock is underpriced.

Lance and Alex have 70 pencils. Lance has 4 times as many pencils as Alex. Alex's pencils are shared equally among 2 children. H

gogolik [260]

let l = lance, and a = alex.

so: l + a = 70

and l = 4a

Putting the value for l in the first equation:

4a +a = 70

5a = 70

a = 14.

So Alex has 14 pencils. And Lance has (70-14) 56 pencils.

And if each child gets half of Alex' pencils, then each child will have 7 pencils.

the perimeter of a rectangle is 62 feet.if the width of the rectangle is 19ft. what is the length of the rectangle

denis23 [38]

Perimeter = 2(l+w) or 2(length+width)

So far you have the width, which is 19feet. Since you have two sides of the rectangle which are 19 feet, add 19+19=38

Subtract 62-38 to get 24.

You now have the length of both of the sides combined. So you need to divide 24/2 = 12
The length of the rectangle = 12ft.
