Answer:

Assume that we want 90% confidence that the sample mean is within one-half year of the population mean. Does it seem reasonable to assume that the ages of female statistics students have less variation than ages of females in the general population? The required sample size is . (Round up to the nearest whole number as needed.) Does it seem reasonable to assume that the ages of female statistics students have less variation than ages of females in the general population? A. Yes, because statistics students are typically younger than people in the general population. O B. No, because there is no age difference between the population of statistics students and the general population. O C. No, because statistics students are typically older than people in the general population.

Answer:

242.76m^2

Step-by-step explanation:

Given data

Height=18m

Volume=4,374m^3

We know that the expression for the volume of a cylinder is

V=πr^2h

substitute

4374=3.142*r^2*18

4374=56.556*r^2

4374/56.556=r^2

77.339=r^2

r=√77.339

r= 8.79m

But the area of a circle is expressed as

A= πr^2

A=3.142*8.79^2

A=3.142*77.2641

A=242.76m^2

Hence the area of the base is 242.76m^2

The total volume of the composite figure is 64 in³.

The volume of a rectangular prism, V = lwh where

Since horizontal rectangular prism has a length of eight inches, a width of two inches, and a height of two inches. So,

So, its volume V' = lwh

= 8 in × 2 in × 2in

= 32in³

Since the vertical rectangular prism connected at the right end of the other prism has a length of two inches, a width of two inches, and a height of eight inches. So,

So, its volume V" = lwh

= 2 in × 2in × 8 in

= 32 in³

The volume of the composite figure V"' = V' + V"

= 32 in³ + 32 in³

= 64 in³

So, the total volume of the composite figure is 64 in³.

Answer:

The answer is $25

Explanation:

area of a circle = pi x r^2

using 3.14 for pi

radius = 36/2 =18

area = 3.14 x 18^2 = 1017.36 square inches

1 sq ft = 144"

1017.36/144 = 7.065 sq ft

7.065*3.50 = $24.73 to the nearest dollar = $25

Answer:

It would be 30$.

Step-by-step explanation:

Lets break this down.

50% off 100 would be 50. 50 is half of 100, therefore we know that 50% is half off of something.

We can either divide 60 by 2, or split 60 in half. In turn, we receive 30.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The ordered pair that describes a point that is located 4 units to the left of the origin and 2 units below the x-axis is (-4, -2)

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

The point is located 4 units to the left of the origin and 2 units below the

x-axis.

4 units to the left of the origin.

This means,

x = -4

2 units below the x-axis.

This means,

y = -2

The coordinate in the form of ordered pair is (-4, -2).

Thus,

The ordered pair that describes a point that is located 4 units to the left of the origin and 2 units below the x-axis is (-4, -2)

The length of the side AC will be equal to 5.69 cm

A figure consisting of four sides connected together and forming a total angle of 360 degrees is called a quadrilateral.

Given that:-

ABCD is a kite, so AC I DB and DE= EB.

AD = 4 cm BD = 4 cm and CD = 3 cm.

The side AC will be calculated as:-

Since AC is bisecting the line BD so BE = ED and BE = 2 cm and ED = 2 cm. WE have AD = 4 cm so we will calculate AE first by using the Pythagorean theorem.

AE² = AD² - ED²

AE² = 4² - 2²

AE² = 16 - 4 = 12

AE = √12 = 3.46 cm

Similarly, we will find the value of EC.

EC² = 3 ² - 2²

EC² = 9 - 4 = 5

EC = √5 =2.23

WE know that AC = AE + EC

AC = 3.46 + 2.23

AC = 5.69 cm

Therefore the length of the side AC will be equal to 5.69 cm

1) x = 15

Step-by-step explanation:

We use the Pythagorean thm for these questions. Where a and b are the legs (So order doesn't matter), and where c is the hypotenuse

1)

a² + b² = c²

9² + 12² = x²

81 + 144 = x²

x² = 225

You square root each side so you can get rid of the exponent on x.

1.) Finding the top volume mean multiplying the height of the top (6 m) , width, and length.

2.) Finding the bottom is the height of the bottom (5 m) , width, and length.

3.) Finding the total is adding both bottom and top!
