Based on the game involving rolling a number cube, the applicable statements are:
The sample space is {1, 2, 3, 4, 5, 6}. The expected value for the game is 0. The game is fair because the expected value is equal to 0.What happens in a game involving rolling a number cube?There are six sides of a number cube which means that the sample space is all the sides the cube can land on which are 1,2,3,4,5, and 6.
Because there are 3 odd numbers which can give you a negative point, and 3 even numbers which can give a point, the expected value is 0 as these cancel each other out.
This makes the game fair because situations that have an expected value of 0 are considered fair because there are no expected losses or profits.

Gabriel models the volume of a popcorn box as a right rectangular prism and the box can hold 74 cubic inches of popcorn when it is full. its width is 3 and 1/2 in and its height is 77 in. find the length of the popcorn box in inches. round your answer to the nearest tenth if necessary.
If the volume of the popcorn box is 74 cubic inches. Then the length of the popcorn box in inches will be 0.3 inches.
What is a rectangular prism?A rectangular prism is a closed solid that has two parallel rectangular bases connected by a rectangle surface.
Gabriel models the volume of a popcorn box as a right rectangular prism and the box can hold 74 cubic inches of popcorn when it is full.

Answer: the real answer is 3 inches not 0.3.
Step-by-step explanation:
Formula: V=lwh
You are searching for its length, so if width is 3 1/2 then it will convert to 3.5
V=lwh
75=L(3.5)(7)
=3.02040816
L= 3.0

A cone has a radius of 2 feet and a height of 6 feet. How many cones of liquid would it take to fill a cylinder with a diameter of 4 feet and a height of 6 feet? Complete the explanation. The radius of the cylinder is the same as the radius of the cone. The height of the cylinder is double the height of the cone. So, it will take cones to equal the volume of the cylinder.

help pleasee!!?? Thank u
Answer: 9,156.24 ft³
Step-by-step explanation:
The formula for the volume of a cylinder is V = πr²h. The problem gives us both the radius and the height, so we have all necessary values to solve by substitution:
r = 9
h = 36
V = π(9)²×36
= 81 × 36 × π
= 2916π
= 9,156.24 ft³

Answer:
5 seconds and 488 ft
Step-by-step explanation:
(a)
given a quadratic in standard form
y = ax² + bx + c ( a ≠ 0 ), then
the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
y = - 16x² + 160x + 88 ← is in standard form
with a = - 16 and b = 160 then
[tex]x_{vertex}[/tex] = - [tex]\frac{160}{-32}[/tex] = 5
the maximum height is at the vertex, the turning point on the graph
then it takes 5 second to reach its maximum height
(b)
to find the maximum height substitute x = 5 into the equation
y = - 16(5)² + 160(5) + 88
= - 16(25) + 800 + 88
= - 400 + 888
= 488
maximum height is 488 ft

Answer:
65.8
Step-by-step explanation:
The Law of Sines can be used to find side values from angles when a side and its opposite angle are given.
__
The relation is ...
a/sin(A) = b/sin(B)
Solving for 'a' gives ...
a = b·sin(A)/sin(B) = 100·sin(18°)/sin(28°)
a ≈ 65.8

The value of minor arc, major arc and central angles given below:
What is an arc?An arc measure is an angle the arc makes at the center of a circle, whereas the arc length is the span along the arc.
Given: BOF= 126
angle BOF= angle COE= 126 (Vertically opposite angle)
Now,
angle BOF + angle BOC= 180 (Linear pair)
BOC=180-126= 54
and, COE= COD+ DOE
= COD+COD
126 =2COD
COD= 63
now, BOD= BOC++COD
= 54+63
= 117
Arc length of BCD= 87/360*2πr

2. minor arc:
arc BF= 126/360* 2πr

arc DE= 63/360*2πr
= 1.099r
arc CD= 63/360*2πr= 1.099r
arc CDE=126/360*2πr
= 2.198 r
3. major arc
arc BFED= 243/360*2πr

arc FBCD= 243/360*2πr

Nevaeh leans a 22-foot ladder against a wall so that it forms an angle of 64 degrees with the ground. How high up the wall does the ladder reach? Round your answer to the nearest hundreth of a foot if necessary
Answer:
19.77 ft
Step-by-step explanation:
The ladder is the hypotenuse of a right triangle ....one leg is the house , the other leg is the ground.
sin 64 = opposite/hypotenuse = height /22
sin 64 = height / 22

A total of 337 tickets were sold for the school play. They were either adult tickets or student tickets. There were 73 fewer student tickets sold than adult tickets. How many adult tickets were sold?
The total number of adult tickets sold for the school play is 205 tickets if the total of 337 tickets were sold for the school play.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let's suppose the number of adult tickets is x
So the number of student tickets is (x-73)
x + (x-73) = 337
2x—73 = 337
2x = 410
x = 205 tickets
Thus, the total number of adult tickets sold for the school play is 205 tickets if the total of 337 tickets were sold for the school play.
