a cube has 6 faces that are red, yellow, or blue. maggie rolls the cube 20 times and records the color facing up.
Answers
From the information given, the number of outcomes from 20 trials are
Red = 7
Yellow = 6
Blue = 7
From the outcomes, since the number of outcomes for red and blue are equal, it means that the number of red and blue faces would be the same. The only option where they are the same is the last option. Since the total number of faces is 6, the remaining face which is yellow is possibly 2. Thus, the correct option is
The cube has 2 red faces, 2 blue faces and 2 yellow faces

a tunnel is in the shape of a parabola. The maximum height is 48 and it is 18 m wide at the base. What is the vertical clearance 3 m from the edge of the tunnel?
Answers
The vertical clearance 3 m from the edge of the tunnel at 19.1 m.
What is referred as the parabola?A parabola is just a U-shaped plane curve in which any point is an equal distance from both a fixed point (recognized as the focus) and a fixed straight line (known as the directrix).For the parabola's maximum height is 50 m, its formula is of the form.
y = ax² + 48
The vertex is located at in this equation (0,48).
Is for vertex to be the maximum of y, the constant a must be negative.
The parabola's base is 18 m wide.
As a result, the x-intercepts seem to be (9,0) and (-9,0).
Set x = 9 and y=0 to obtain
a(9²) + 48 = 0
81a = -48
a = -0.59
The equation of the parabola is
y = - 0.59x² + 48
At 21.32 m of the edge of the tunnel, x = 9 - 2 = 7 m.
Thus, the height of the tunnel (vertical clearance) at x = 7 m is
h = y(7)
= -0.59(7²) + 48
h = 19.09
h = 19.1 m
Thus, the vertical clearance 3 m from the edge of the tunnel at 19.1 m.

can you please solve this practice problem for me I need assistance C. -1/2 and D. 1/2
Answers
We are going to select the points when x = 0 and x = 2.
Observing the graph we see that when x = 0, then y = 1 - (0,1)
when x = 2, then y = 2 - (2, 2)
Now we have two points:
(x₁, y₁) = (0, 1)
(x₂, y₂) = (2, 2)
Step 2: change of variablesWe are going to find how much the variables change from point 1 to point 2
Change of x:
Δx = x₂ - x₁ = 2 - 0 = 2
Δx = 2
Change of y:
Δy = y₂ - y₁ = 2 - 1 = 1
Δy = 1
Step 3: slopeThe slope, m, is the division of the two found changes:
m = Δy/Δx = 1/2

Answers
Vanessa took 75 sec time to cycle from her home to the beach
What is Speed?Speed is the time rate at which an object is moving along a path
Speed =Distance/time
Given,
Vanessa cycled from her home to the beach at a speed of 18 meters per second
Speed=18 m/s
The distance between her home and the beach is 1,350 m.
Distance=1,350 m
Now we need to find the time for Vanessa to cycle from her home to the beach
Time=?

When two points lie on the same line are called collinear. When they lie on the same plane they are called coplanar.
Points that lie on the same plane are not necessarily collinear.
When points are collinear, they lie on the same plane. Then when points are collinear they are necessarily coplanar. But when they are coplanar they are not necessarily colinear.
This means that points that lie on the same line are collinear and coplanar too.

Find the volume of this object.Use 3 for π.Volume of a CylinderV= πr²h6 in8 in12 in V[?]in³310 in
Answers
ANSWER
V = 366 in³
EXPLANATION
This object is composed of two cylinders. The total volume of the object is the sum of the volumes of the cylinders.
As stated in the problem, the volume of a cylinder is given by,
[tex]V=\pi r^2h[/tex]Where r is the radius of the base and h is the height of the cylinder.
For the tallest cylinder, the diameter is 6 in - so the radius is 3 in, and the height is 8 in. Using 3 for π, the volume is,
[tex]V_1=3\cdot3^2in^2\cdot8in=216in^3[/tex]For the shortest cylinder, the diameter is 10 in, so the radius is 5 in, and the height is 2 in. The volume of this cylinder is,

Is this game fair?The game is not fair and not favorable to player.The game is not fair, but favorable to player.The game is fair.The game is fair, but not favorable to player.
Answers
Hello there. To solve this question, we need to analyze the probabilities for each case and see if the game is fair or not and also favorable to the player.
Sophia rolls a dice. If 5 turns up, she gets $2; If 6 turns up, she gets $3; If 2 turns up, she loses $10; She neither wins nor loses if any other face turns up.
First, let's remember something that will be important: a dice only haves 6 faces.
As we can see, she is winning (getting money) if 2 out of 6 faces turns up (5 and 6), and is losing if 1 out of 6 faces turns up (2). She is neither winning or losing if 3 out of 6 faces turns up (1, 3, 4).
About the fairness of the game, there are only 1 case she loses and 2 cases she wins something. We could only say the game is fair if the amount of winning cases were equal to the amount of losing cases. The game is not fair.
About being favorable, we'll consider it being unfavorable just the case that she loses money. The first and third cases, in which she gets money or doesn't get or lose money are favorable to her.
Since only 1 out of 6 faces makes her lose, then the game is favorable to the player.
Final answer: The game is not fair, but favorable to the player.
