diameter 67 feet
Someone would travel about
feet during one ride on the Ferris wheel.
Answer:
2,945 feet
Step-by-step explanation:
Find the circumference.
C = dπ
C = 67(3.14)
C = 210.38
Since there are 14 revolutions, multiply the circumference by 14.
210.38 x 14 = 2945.32

Natalie is playing a game using a fair coin. Contestants win the game if the fair coin lands tails up. The theoretical proabaility that the coin will lamd tails is ? If 250 contestants play the game, about of them are expected to win
The theoretical probability of landing on tails is P = 0.5, and out of the 250 contestants, around 125 will win the game.
About how many contestants will win?
The coin has two possible outcomes, so if it is a fair coin, the probability for each of the outcomes will be 0.5 (this is the theoretical probability for a fair coin, where all the outcomes have the same probability).
Now, we know that a person wins if the coin lands tails up, and the probability of landing on tails is 0.5
Then, for a sample N, we can expect that about 0.5*N of the participants win.
In this case, the sample is 250, then we can expect that:
0.5*250 = 125
Around 125 of the contestants win the game

Bella is typing a 400 word essay. She types 50 words in 2 minutes.
Enter an equation in the form of y=mx+b, that represents the number of words (y) remaining to type after x minutes.
Answer:
[tex]y=25x[/tex]
Step-by-step explanation:
If Bella types 50 words in 2 minutes, we can divide 50 by 2 to see how many words she types in 1 minute.
[tex]50/2=25[/tex]
So, Bella types 25 words per minute. When she first began writing her essay, she did not have words to start with, so there is no y-intercept ([tex]b[/tex]).
Therefore, the equation that represents this relation is [tex]y=25x[/tex].
Solving the equation
We can divide 400 by 25 to determine how many minutes it would take her to finish her essay.
[tex]\frac{400}{25} =16[/tex]
Therefore, it will take her 16 minutes to complete her essay.

Which of the following shapes can be a cross section of a cylinder?
Answer:
Below
Step-by-step explanation:
The second ( Oval) (The cross-section of a slanted plane through curved body of the cylinder)
The third (Circle). ( The cross section of a plane parallel to the base)
The fifth (Rectangle) (The vertical cross section of a plane through the diameters of the top and bottom of the cylinder.).
The shapes can be used are oval, circle and rectangle.
What is Geometry?Geometric shapes are defined as figures closed by a boundary which is made by combining the definite amount of curves, points, and line segments. Each shape has a unique name such as circle, square, triangle, rectangle, etc. In real life, we are surrounded by various basic geometric shapes, like the slice of a pizza is in the shape of a triangle, doors or windows are in the shape of a rectangle, and many more.
Types of Geometric ShapesIn geometry, when an object or a shape is not connected with both ends, it is considered an open geometric shape. When an object or a shape is connected with both ends it is considered a closed geometric shape. There are two types of geometric shapes, classified as:
Two-dimensional: These are 2D shapes that have only the x-axis and y-axis. They are flat structures with 2 dimensions. For example, triangle, square, rectangle, etc.Three-dimensional: These are 3D shapes that have an x-axis, y-axis, and z-axis. The z-axis represents the height of the object. They are solid structures with 3 dimensions. For example, cube, cuboid, etc.First, oval can be used as the cross-section of a slanted plane through curved body of the cylinder.
Then, circle (plane parallel to base)
Then, rectangle the vertical cross section of a plane through diameters.

the two tanks wi equal 64
x=64
Answer:
w = 64 weeks

From the information, we have two equations that we will need to set equal to each other to find the number of weeks, w, it takes for both tanks to hold the same amount:

What is the median of the data set represented by the dot plot?
Enter the answer in the box.
A number line with line with two dots above the number 10, one dot above the number 12, one dot above the number 13, one dot above the number 14, one dot above the number 15, one dot above the number 18, and two dots above the number 19.
Answer:
Median is 14Step-by-step explanation:
The median is the middle number (or average of middle two numbers if data set has even number of elements) of the data set.
According to the graph, the data set has 9 elements.
The 5th number in the set is the median, which is 14
14
Step-by-step explanation:Step-1: Prepare a table that represents the number of dots above a specific number:
[tex]\text{Dots above 10}: || \\ \text{Dots above 12}: | \\ \text{Dots above 13}: | \\ \text{Dots above 14}: | \\ \text{Dots above 15}: | \\ \text{Dots above 18}: | \\ \text{Dots above 19}: ||[/tex]
Step-2: Put the values in ascending or descending upon your choice:
[tex]10, 10, 12, 13, 14, 15, 18, 19, 19[/tex]
Step-3: Determine wether the total number of digits in the data is even or odd. This will help us find the median.
[tex]\text{9 digits in total}\\\\\text{The number of digits is \underline{odd}}[/tex]
Since the number of digits is odd, we will use the formula (a + 1)/2
(where a is the number of digits in the data)
Step-4: Substitute the number of digits in the formula.
⇒ (a + 1)/2th
⇒ (9 + 1)/2th
⇒ (10)/2th
⇒ 5th digit is median
Step-5: Look for the 5th digit in the data. That digit is your median.
[tex]10, 10, 12, 13, \underline{\underline{14}}, 15, 18, 19, 19[/tex]

A right triangle with side length 10 feet, hypotenuse of 22 feet, and side of h.
What is the height of the pole? Round to the nearest hundredth.
12.00 feet
19.60 feet
24.17 feet
38.40 feet
✰ Concept Used :-
⠀
In this question, we can clearly observer that the diagram shows a right angled triangle. And, we have been provided with the value of base, and the value of hypotenuse, using the pythagoras theorem, now we can easily find out the value of the perpendicular i.e. the value of the side h. According to the pythagoras theorem, square of hypotenuse is equal to the sum of square of perpendicular and square of side respectively. Therefore, square of side is equal to the difference of square of hypotenuse and square of perpendicular.
⠀
✰ Given Information :-

✰ To Find :-

2(0) + 6(0) = 0; Once we multiply both sides we end up adding 0 and 0, so it equals 0
9(0) = 0
