[tex](3.14 \times {9}^{2} \times \frac{14}{3} ) + ( \frac{4}{3} \times 3.14 \times {9}^{3} \times \frac{1}{2} )[/tex]

Answer: 75

Step-by-step explanation:

Add the values given in the table

16+15+20+14+15 = 80

Yellow happens 20 times out of the 80 times total.

The experimental probability of yellow is 20/80 = 1/4 = 0.25 = 25%

If we do 300 trials, then we predict yellow to happen 0.25*300 = 75 times.

QUESTION 1

The value of the x for the given square such that its perimeter is 28 meters will be 3.7 meters.

What is a square?

A square is a geometrical figure in which we have four sides each side must be equal and the angle between two adjacent sides must be 90 degrees.

Area of square = Side²

The perimeter of the square = 4 × side

As per the given square perimeter.

4(x + 3.3) = 28

x + 3.3 = 7

x = 3.7 meters.

Hence"The value of the x for the given square such that its perimeter is 28 meters will be 3.7 meters".

Answer:

1634.77

Step-by-step explanation:

2πr= circumference

80.89=2πr

80.89/ πr= r

r= 12.87

area= πr^2

area= 12.87 π^2

area= 1634.77

Answer:

520.89 cm²

Step-by-step explanation:  

IN GIVEN QUESTION

The hubcap of the tire's circumference is 80.89 centimetres.

We must determine the radius of this hub cap, which we can do by using the circumference method to determine its area

now :

2πr = 80.89 cm

r = 80.89/ 2× 3.14

r = 12. 88 cm ( approx)

Area of hub cap = πr²

Area = 3.14 ×12.88² = 520.89 cm²

Answer:

The classical inequalities are several generalized inequalities that have wide use in algebra. They are often used for determining the minimum and maximum values of functions. Although maximums and minimums can be found using methods from calculus, the application of a classical inequality is often a simpler approach. In conclusion, inequality is important for determining the calculus and the numbers to solve a problem.

Step-by-step explanation:

According to the information, the distribution of the data is multimodal distribution.

To find the type of distribution of the graph we must analyze the graph and identify the values and the frequency of each of the values. Based on this information, we can establish that the type of distribution of this graph is multimodal distribution.

According to the data in the graph, we can infer that it is a multimodal distribution because it has low and high points in different variables and does not have an established pattern.

The amount of metal used to make the can = surface area of cylindrical can, which is: C. 20π in².

A can is a cylinder.

Surface area of a cylinder = 2πrh + 2πr²

Thus:

Amount of metal used to make the can = surface area of the can

r = 4/2 = 2 in.

h = 3 in.

Therefore:

Surface area = 2×π×2×3 + 2×π×2²

Surface area = 12π + 8π

Surface area = 20π in².

Answer: 35

Step-by-step explanation:

20%=7

100%=35

Answer: The answer is 35

Step-by-step explanation:

No, the total cost is not directly proportional to the number of attendees because there is a flat fee of $4 that does not depend on the number of attendees. If the total cost were directly proportional to the number of attendees, then the cost per attendee would be constant regardless of the number of attendees, but in this case, the cost per attendee decreases as the number of attendees increases due to the fixed flat fee.

Explanation:

Start with the set {1, 2, 3, 4, 5, 6}

Stick "H" in front of each item to get {H1, H2, H3, H4, H5, H6} which represents half of the sample space. Something like H2 means "coin flipped heads and the number cube rolled a 2".

The other half of the sample space involves replacing each H with T. Which explains how we get T1, T2, T3, T4, T5, T6

Overall, the sample space is:

{H1, H2, H3, H4, H5, H6, T1, T2, T3, T4, T5, T6}

It might help to organize things into a table like this:

[tex]\begin{array}{|c|c|c|c|c|c|c|} \cline{1-7}& 1 & 2 & 3 & 4 & 5 & 6\\\cline{1-7}H & H1 & H2 & H3 & H4 & H5 & H6\\\cline{1-7}T & T1 & T2 & T3 & T4 & T5 & T6\\\cline{1-7}\end{array}[/tex]

Or it could be written like this:

[tex]\begin{array}{|c|c|c|} \cline{1-3}& H & T\\\cline{1-3}1 & H1 & T1\\\cline{1-3}2 & H2 & T2\\\cline{1-3}3 & H3 & T3\\\cline{1-3}4 & H4 & T4\\\cline{1-3}5 & H5 & T5\\\cline{1-3}6 & H6 & T6\\\cline{1-3}\end{array}[/tex]

Either table demonstrates how there are 6*2 = 12 items in the sample space.

D) Multiply one dimension of the prism by two and keep the other dimensions the same.

Step-by-step explanation:

When multiplying a volume of a rectangular prism regularly it would be B×h or l×w×h would be 10×2×5 = [tex]100cm^{3}[/tex].

However if doubled, or multiplied by 2 our new result would be [tex]200cm^{3}[/tex]. The way to find this is by multiplying only one dimension, or side, as the rest will remain the same.

There are 3 possible equations you could do with the given information.

(10×2)×2×5, 10×(2×2)×5, or 10×2×(5×2).

All of these, individually multiply up to 200 which is also double the amount of the regular volume.
