Step-by-step explanation:

The surface area of the cube is 6 ft².

It is a polygon having six faces.

The volume of a cube is side³.

We have,

Volume = 1 ft³

The surface area of the cube = 6a²

Now,

Volume = 1 ft³

This means,

Side = 1 ft

a = 1 ft

So,

The surface area of the cube.

= 6a²

= 6 x 1²

= 6 ft²

Thus,

The surface area of the cube is 6 ft².

Answer:

[tex] V_{total} = 26460 \pi~cm^3 [/tex]

[tex] V_{total} = 83127~cm^3 [/tex]

Step-by-step explanation:

The solid is made up of 2 cones and a cylinder.

Upper cone:

radius = 21 cm

height = h_1 = 70 cm - 35 cm = 35 cm

Cylinder:

radius = 21 cm

height = h_2 = 35 cm

Lower cone:

radius = 21 cm

height = h_3 = 40 cm

[tex] V_{total} = V_{upper~cone} + V_cylinder} + V_{lower~cone} [/tex]

[tex] V_{total} = \dfrac{1}{3} \pi r^2 h_1 + \pi r^2 h_2 + \dfrac{1}{3} \pi r^2 h_3 [/tex]

[tex] V_{total} = \dfrac{1}{3}(\pi)(21~cm)^2(35~cm) + (\pi)(21~cm)^2(35~cm) + \dfrac{1}{3}(\pi)(21~cm)^2(40~cm) [/tex]

[tex] V_{total} = \dfrac{1}{3}(\pi)(441~cm^2)(35~cm) + (\pi)(441~cm^2)(35~cm) + \dfrac{1}{3}(\pi)(441~cm^2)(40~cm) [/tex]

[tex] V_{total} = (147~cm^2)(35~cm)(\pi) + (441~cm^2)(35~cm)(\pi) + (147~cm^2)(40~cm)(\pi) [/tex]

[tex] V_{total} = 5145\pi~cm^3 + 15435\pi ~cm^3 + 5880\pi~cm^3 [/tex]

[tex] V_{total} = 26460 \pi~cm^3 [/tex]

[tex] V_{total} = 83127~cm^3 [/tex]

Answer:

132

Step-by-step explanation:

a straight line is 180% , so if the other triangle has a 48% we would subtract 180% by 48%.

Answer:

132

Step-by-step explanation:

Since those two angles are linear, they would form to make 180 degrees. So 180-48 is 132.

Answer:

10826

Step-by-step explanation:

Answer:

1 hour = 60× 60= 3,600 seconds

3 hour = 3600 ×3=10,800 second

So, 3 hours 26 seconds = 10,800+26

= 10,826 second (Answer )

Answer:

1. Since [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex], these conditions are met.

2. Approximately normal.

3. 0.35

4. 0.0389

Step-by-step explanation:

Central Limit Theorem:

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex], as long as [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex]

Let's say you want to poll a random sample of 150 students on campus to see if they prefer to take online classes.

This means that [tex]n = 150[/tex].

35% of all students actually prefer to take classes online

This means that [tex]p = 0.35[/tex]

1. Discuss the conditions necessary to use the normal curve to model this sampling distribution and explain whether or not they are met.

The conditions necessary are [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex].

We have that

[tex]np = 150*0.35 = 52.5 \geq 10[/tex]

[tex]n(1-p) = 150*0.65 = 97.5 \geq 10[/tex]

Since [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex], these conditions are met.

2. If the normal model is appropriate for this distribution, what shape would you expect it to have?

By the Central Limit Theorem, approximately normal.

3. If you were to use the normal model for this p-hat sampling distribution, what value would be at the center of your sampling distribution? In other words, what value would all of those sample proportions center around?

The mean, which by the Central Limit Theorem, is [tex]\mu = 0.35[/tex].

4. What would be the standard deviation of this sampling distribution?

By the Central Limit Theorem,

[tex]s = \sqrt{\frac{0.35*0.65}{150}} = 0.0389[/tex]
