Answer:

P=2l+2w

We are given,

P=40cm

l=2w+2

Plug these into the first formula and solve for the dimensions,

length and width, of the rectangle:

40=2(2w+2)+2w Simplify

40=4w+4+2w

40=6w+4

36=6w

6=w OR the width is 6cm, therefore,

the length is

l=2(6)+2

l=14cm

To calculate the area of a rectangle, A=lw,

plug the length,14cm, and the width, 6cm, into this formula

A=(14)(6)

A=84cm2 OR the area of the rectangle is 84cm2.

A pharmaceutical testing company wants to test a new cholesterol drug. The average cholesterol of the target population is 200 m

Rom4ik [11]

Answer:

The required range is 237.5 to 275.

Step-by-step explanation:

Consider the provided information.

The average cholesterol of the target population is 200 mg and they have a standard deviation of 25 mg.

The the value of μ = 200 and the $\sigma=25$

The company wished to test a sample of people who fall between 1.5 and 3 z-scores above the mean.

Let the value of z is 1.5.

Now use the z score formula: $z=\frac{(x -\mu)}{\sigma}$

Substitute the respective values in the above formula.

$1.5=\frac{(x -200)}{25}$

$37.5=x -200$

$237.5=x$

Now let the value of z is 3.

Substitute the respective values in the z score formula.

$3=\frac{(x -200)}{25}$

$75=x -200$

$275=x$

Hence, the required range is 237.5 to 275.

Vlad [161]

Answer:

196.48

Step-by-step explanation:

Area of the semi-circle:

A= (πr^2)/2

A= (3.14 x 64)/2

A= 100.48

Area of triangle:

A= 1/2bh

A= 1/2(16)(12)

A= 96

96 + 100.48= 196.48
