The spinner below has three regions: $5, $0, and $10. To play the game, you spin one time and then you win the amount in the region that the spinner lands on. a.) What is the expected value for the game? b) If you have to pay $10 to play, is it a fair game? *
a) $5.00 b) no
a) $4.79 b) yes
a) - $ 8.75 b) no
a) $ 3.00 b) yes
Answers
Answer:
$5.00 ; no
Step-by-step explanation:
Given that:
135 / 360 = 0.375
90 / 360 = 0.25
135/ 360 = 0.375
X ___ 5 _____10 _____ 0
P(x): _0.25___0.375___0.375
Expected value :
ΣX*p(X) :
5(0.25) + 10(0.375) + 0(0.375)
1.25 + 3.75 + 0
= $5
b) If you have to pay $10 to play, is it a fair game?
For the game to be fair :
Amount paid = Expected winning
$10 ≠ $5
Since, amount paid is greater than expected winning, then the game is not fair

Answers
The equivalent expression of 25 - 64 are "a), b) and c)"
The given expression is:
25 - 64
To find, the equivalent expressions are:
a) 25 + 40x - 40x - 64
= 25 - 64, is the equivalent expression.
b) 25 + 13x - 13x - 64
= 25 - 64, is the equivalent expression.
c) (5 + 8)(5 - 8)
Using the algebraic identity,
(a + b)(a - b) =

Answer: option A, B, C are equivalent to [tex]25x^4-64[/tex].
We check each option by simplifying:
A) [tex]25x^4 + 40x - 40x - 64 = 25x^4-64[/tex].
B) [tex]25x^4 + 13x - 13x - 64 = 25x^4-64[/tex]
C) [tex](5x^2 + 8)(5x^2 - 8)=(5x^2)^2-8^2=25x^4-64[/tex]
D) [tex](x^2 + 13)(x^2 - 13)=(x^2)^2-13^2=x^4-169[/tex]
E) [tex](5x^2 - 8)^2=(5x^2)^2-2(5x^2)(8)+8^2=25x^4-80x^2+64[/tex].
So option A, B, C are equivalent to [tex]25x^4-64[/tex].

A turtle travels one half of a foot in 4 seconds. How many feet will a turtle travel in 7 seconds?
Answers
Answer: 10.5 inches or .875 feet.
Step-by-step explanation:
First calculate the SPEED = Distance /Time. So 1/2 of a foot = 6 inches so distance of 6 inches divided by time of 4 sec = s 1.5 (inches) per sec. So using Distance = speed x time we calculate 1.5in x 7 sec= a distance of 10.5 inches or 10.5 inches divided by 12in that is in a foot = .875 feet.

Elevation is a measure of height in relation to sea level. The highest feature on Earth is Mount Everest with an elevation +29,029 feet. The lowest feature on Earth is the Challenger Deep with an elevation -35,797 feet. What elevation does sea level represent in this scenario? Which feature is farther from sea level?
Answers
Answer:
[tex]Sea\ Level = 0\ ft[/tex]
The farthest point is the Challenger Deep
Step-by-step explanation:
Given
[tex]Highest = +29029ft[/tex]
[tex]Least = -35,797ft[/tex]
Solving (a): The sea level
Both elevations had signs in front of them.
The sea level is the point at the neutral level, neither positive nor negative.
Hence:
[tex]Sea\ Level = 0\ ft[/tex]
Solving (b): Farthest Point.
The farthest point is the one with the highest magnitude.
Comparing
[tex]Highest = +29029ft[/tex] to [tex]Least = -35,797ft[/tex]
-35,797 ft has the highest magnitude.
Hence:
The farthest point is the Challenger Deep

What is a Rectangle?Rectangle is a type of quadrilateral that has its parallel sides equal to each other, opposite sides are equal to each other, and all the angle are equal to 90 degrees.
How to determine this
The perimeter of a Rectangle = 2 ( Length + Width)
Where the Width = 2 ft
Length = 28 ft longer than Width
i.e W + 28
Length = 2 + 28 = 30 ft
To calculate the perimeter if the path
Perimeter = 2( 30 + 2)
Perimeter = 2(32)
Perimeter = 64 ft
Therefore, the perimeter of the rectangular path is 64 ft

Answers
Answer:
the value of y is -3
Step-by-step explanation:
x = -6
sub -6 to the equation
8(-6) - 5y = -33
-48 - 5y = -33
-5y = -33 + 48
-5y = 15 (divide both sides by negative 5)
y = -3

Answer: Systematic sampling
Step-by-step explanation: Systematic sampling usually takes an ordered technique or process in dealing with samples. Systematic sampling could assume a randomized start point in selecting observations, However, every other successive points usually follow a fixed order or selection process. In the scenario above, the manager sampling choice involves an ordered and fixed selection process whereby every fifth sample after the initial point is considered. Hence, resulting in predictable points, such as 6th, 11th, 16th, 21st, 26th, 31st,...and so on.
what is the slope if a line passes through the points (28,86) and (34,83)
Answers
Answer:
The slope is -0.5 or -1/2
Step-by-step explanation:
the slope of a line is easily calculated by hand using small, whole number coordinates. The formula becomes increasingly useful as the coordinates take on larger values or decimal values.
It is worth mentioning that any horizontal line has a gradient of zero because a horizontal line has the same y-coordinates. This will result in a zero in the numerator of the slope formula. On the other hand, a vertical line will have an undefined slope since the x-coordinates will always be the same. This will result the division by zero error when using the formula.

ILL MAKE MOST BRAINLIEST!!!
Answers
Given:
There exist a proportional relationship between x and y.
To find:
The equation which represents a proportional relationship between x and y.
Solution:
If there exist a proportional relationship between x and y, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
where, k is constant of proportionality.
We know that, proportional relationship passes through the origin because (0,0) satisfy [tex]y=kx[/tex].
For x=0, check which equation has y=0.
In option A, [tex]y=-3(0)-2=-2[/tex].
In option B, [tex]y=9[/tex].
In option C, [tex]y=4(0)=0[/tex].
In option D, [tex]y=3(0)+1=1[/tex]
Only in option C, we have a equation of the form [tex]y=kx[/tex] with 4 as constant of proportionality and it passes through (0,0).
Therefore, the correct option is C.
