I play a gambling game in which I will win different amounts of money with different likelihood's. Suppose that I win X dollars with a probability of P(X) (if C is negative I am losing money). The distribution is as follows: what is the appropriate value of P?
Answers
Answer:
[tex]p = 0.05[/tex]
Step-by-step explanation:
Given
See attachment for the distribution
Required
Find p
To find p, we make use of:
[tex]\sum P(x) = 1[/tex]
So, we have:
[tex]0.50 + 0.25 + 0.13 + 0.07 + p = 1[/tex]
[tex]0.95 + p = 1[/tex]
Make p the subject
[tex]p = 1 - 0.95[/tex]
[tex]p = 0.05[/tex]

Translation can be accomplished by reflecting across two parallel lines. The amount of translation is double (twice) the distance between the lines. Any two lines with the same spacing will give the same translation.
Here, the translation is 4 up and 4 right. The amount by which each point is translated is 4√2 units in the direction "northeast", that is, along a line with a slope of 4/4 = 1.
Any line of reflection is a perpendicular bisector of the segment joining the original point and its image. This means we need to identify two lines that have a slope of -1 and that are separated by (4√2)/2 = 2√2 units.
The attachment shows that two lines with this slope that have a separation of 2√2 will have y-intercepts that differ by 4. (The lines shown happen to be the correct answer choices.)
The offered choices of lines have y-intercepts of {5, 6} and {10, 12}. The only pair of lines with y-intercepts that differ by 4 are y=-x+6 and y=-x+10.
_____
Additional comment
We have made sort of a qualitative argument for the correct answer. If you like, you can say that the two lines of reflection each cause the image to be located halfway to its destination. That mean, for example, for point R(2,2), the first image point is R'(4,4). The line of reflection, as we said above, is the perpendicular bisector of this. It will have a slope of -1 and go through the point (3, 3), so its equation is ...
y -3 = -1(x -3) ⇒ y = -x +6
Similarly, the second (final) image point is R''(6,6). We can find the other line of reflection to be one that has a slope of -1 and goes through the point (5, 5). Its equation is ...
y -5 = -1(x -5) ⇒ y = -x +10
These are two of the equations that are offered as answer choices, so should be selected.
As we said at the beginning, any lines with this spacing will do. We cannot presume at the start that each line of reflection will move the image half the distance.

Which graph shows an exponential function that nears a constant value as x approaches positive infinity and has a y-intercept at (0,3)?
A. X
B. Y
C. Z
D. W
Answers
Answer:
C. Graph Z is the correct answer
Step-by-step explanation:
It touches 0,3 and the right line is going towards infinite positive x’s
#plato
The exponent function of the graph will be W. Then the correct option is D.
What is an exponent?Let b is the base and x is the power of the exponent function and a is the leading coefficient. The exponent is given as
y = a(b)ˣ + c
Where c is the intercept.
Let the leading coefficient will be 1.
Then the equation will be
y = (b)ˣ + c
The exponent function has a y-intercept at (0, 3).
Then the exponent function is given as,
y = (b)ˣ + 2
Some points regarding exponent function.
The exponent function remains positive for the real value of the x.If the value of x approaches to the negative infinity, then the function tends to zero.If the value of x approaches to the positive infinity, then the function tends to infinity.At x = 0, the function interset the y-axis at (0, 3).The exponent function of the graph will be W.
Then the correct option is D.

Beth says 20-5x3 is 45, pat says 20-5x3 is 5. who is right?
Answers
Answer:
Pat is right
Step-by-step explanation:
first multiply/divide then add/subtract,
Beth: 20 - 15 = 45 => 5 ≠ 45
Pat: 20 - 15 = 5 => 5 = 5
Answer:
Pat
Step-by-step explanation:
There is only one correct answer. To find it, you must follow the correct order of operations.
There is a subtraction and a multiplication. There are no parentheses.
The rule is that you must do the multiplication before the subtraction.
20 - 5 * 3 =
= 20 - 15
= 5
In order to get Beth's answer, you'd have to do the subtraction first. If there were parentheses like this: (20 - 5) * 3, then you'd do the subtraction first getting 15 * 3 which is 45, but the problem has no parentheses, so the correct answer is 5.
The correct answer is 5, and Pat is correct.

The perimeter of a rectangle is 14cm. The length of the rectangle is 4 cm more than twice the width. Find the dimensions of the rectangle.
Answers
Answer:
length = 6 cm
width = 1 cm
Step-by-step explanation:
l = length
w = width
l = 4 + 2w
2(4 + 2w) + 2w = 14
8 + 4w + 2w = 14
8 + 6w = 14
6w = 6
w = 1
find length:

Evaluate the piecewise function for the given values of x by
matching the domain values to the range values.
Answers
Answer:
For x = -4f (x) = x + 2
We evaluate the value of x = -4
f (-4) = (-4) + 2
f (-4) = -2
Answer is : f (-4) = -2For x = 4f (x) = -2x + 4
We evaluate the value of x = 4
f (4) = -2 (4) +4
f (4) = -8 + 4
f (4) = -4
Answer is : f (4) = -4For x = 0f (x) = 3x -4
We evaluate the value of x = 0
f (0) = 3 (0) -4
f (0) = 0-4
f (0) = -4
Answer is : f (0) = -4The value of the function at x = 1 is, f(x) = - x - 4 which equals f(1) = - 3.
What is an absolute value function?We know the absolute value function of the modulus function always outputs a positive value irrespective of the sign of the input.
In piecewise terms | x | = x for x ≥ 0 and | x | = - x for x < 0.
Similarly, A piecewise function can also be in terms of without modulus.
Given, f(x) = - x - 4 for x < 3.
f(x) = x² - 7, for 3 ≤x < 12.
f(x) = (120/x) + 5, for x ≥ 12.
Now, At x = 1, It satisfies,
f(x) = - x - 4 for x < 3.
Therefore, f(1) = - (-1) - 4.
f(1) = - 3.

If that chunk was filled in, this would have been a 17 * 15 * 8 rectangluar prism. That would have been 2040 cubic inches. (120 * 17) However, a 3 by 8 by 3 triangular prism is missing.
