In probability, the probability of an outcome is a value between 0 and 1, inclusive. From your list, 1.015 and -0.234 do not fall within this range and thus can't be considered as valid probabilities, whilst 45%, 0.45%, 0.995, 2/3, and 0.66 are valid probabilities.
Explanation:In probability theory, the probability of an outcome is always expressed as a value between 0 and 1, inclusive. In other words, the minimum probability is 0 (representing an event that will not occur) and the maximum is 1 (representing an event that is certain to occur). Probabilities can also be represented as fractions, percentages, or decimal numbers that fall within this range.
Looking at your list, 1.015 and -0.234 cannot be considered valid probabilities, because they fall outside the 0 to 1 range. All percentages should also be converted to decimals before comparison, meaning that 45% is equivalent to 0.45 and is a valid probability, while 0.45% is equivalent to 0.0045 and is also valid. Similarly, 2/3 and 0.66 are valid probabilities because they lie within the 0-1 range.

Graph the system of equations. {2x−y=4x−y=−2 Use the Line tool to graph the lines.
Hear hear! For I have brought you the correct answer... (I took a "snip" of it so you can't see the entire graph but you can see the whole answer.)
By plotting the lines 2x - y = 4 and x - y = -2 using a graphing tool or on graph paper.
To graph these lines, you can start by rearranging them into slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept.
For 2x - y = 4:
-y = -2x + 4
y = 2x - 4
This equation has a slope of 2 and a y-intercept of -4.
For x - y = -2:
-y = -x - 2
y = x + 2
This equation has a slope of 1 and a y-intercept of 2.
Now, you can graph these lines on a coordinate plane by plotting the y-intercepts and using the slopes to find additional points.
Once you have the two lines graphed, their point of intersection represents the solution to the system of equations.

What is the measure of AC?
Enter your answer in the box.
Answer:
The measure of AC is 41°
Step-by-step explanation:
Given : ∠ABC = (4x-3.5)°
Arc AC = (4x+17)°
An inscribed angle: An angle with its vertex on the circle and whose sides are chords.
The intercepted arc : The arc that is inside the inscribed angle and whose endpoints are on the angle.
The Inscribed Angle Theorem : The measure of an inscribed angle is half the measure of its intercepted arc.
Uisng the theorem
[tex]\angle{ABC}=\frac{1}{2} \text{arc(AC)}[/tex]
[tex](4x-3.5)^{\circ}=\frac{1}{2} (4x+17)^{\circ}[/tex]
[tex]2*(4x-3.5)^{\circ}= (4x+17)^{\circ}[/tex]
[tex]8x-7= 4x+17[/tex]
[tex]4x=24[/tex]
[tex]x=\frac{24}{4}[/tex]
[tex]x=6[/tex]
So, Arc AC = (4x+17)° = (4*6+17)° = (24+17)° = 41°
Hence the measure of AC is 41°

Suppose a bay window is a perfect semicircle with an area of 4.5 square feet. If the architect wants to use a scale of 0.5 inch = 1 ft on the floor plan, what is the radius of the bay window on the floor plan?
A) 0.85 inches
B) 1.7 inches
C) 3 inches
D) 3.4 inches
The answer is A) .85 inches
Step-by-step explanation:
A =
1 /2 πr2 4.5 = 1 2 πr2 1.6926 = r
thus, 0.50 in
1 ft = x in 1.6926 ft x = 0.8463
Final answer:
To find the radius of the bay window on the floor plan, calculate the radius of the actual bay window first, apply the scale factor, resulting in a radius of 3.4 inches that is option D is correct.
Explanation:
To find the radius of the bay window on the floor plan, you need to calculate the radius of the actual bay window first. Given the area of the bay window as 4.5 square feet in a semicircle shape, you can use the formula for the area of a semicircle, A = 1/2 * π * r².
Once you find the actual radius, you can then convert it to the scale of 0.5 inch = 1 ft to determine the radius on the floor plan. Remember, the scale factor is the ratio of a length on the drawing to the actual length it represents.
After the calculation, the radius of the bay window on the floor plan is 3.4 inches (Option D).

Julie works for 48 hours per week for 12 weeks during the summer, making $5000. If she works for 48 weeks during the school year at the same rate of pay and needs to make another $5000, how many hours per week must she work?
Since she only needs to make the same amount of money, if she works for 4 times as many weeks, she can work 4 times fewer hours per week, meaning she can work 1/4*48= 12 hours per week.
During the academic year, Julie needs to put in about 12 hours per week of work to earn an additional $5,000 at the same rate of compensation.
To find out how many hours per week Julie must work during the school year to make another $5000,
set up a proportion using the information we already have.
Let's use the ratio of her earnings to the number of hours worked to create the proportion.
During the summer:
Earnings = $5000
Hours worked = 48 hours/week
Weeks worked = 12 weeks
Summer rate of pay = Earnings / (Hours worked × Weeks worked)
Summer rate of pay = $5000 / (48 hours/week × 12 weeks)
Summer rate of pay = $5000 / 576 hours
Summer rate of pay ≈ $8.68 per hour (rounded to two decimal places)
Now, during the school year, she needs to make another $5000.
So, set up the proportion:
School year earnings = $5000
School year rate of pay = $8.68 per hour (same as the summer rate)
School year rate of pay = School year earnings / (Hours worked × Weeks worked)
$8.68 per hour = $5000 / (Hours worked × 48 weeks)
Now, solve for the number of hours worked per week during the school year:
Hours worked × 48 weeks = $5000 / $8.68 per hour
Hours worked × 48 weeks = 576.036
Hours worked ≈ 12 hours per week (rounded to the nearest whole number)
Therefore, Julie must work approximately 12 hours per week during the school year to make another $5000 at the same rate of pay.

here is a sketch of y=x^2 + bx + c. the curve intersects the x-axis at (2,0) and point P. the y-axis at (0,14) work out the x-coordinate of the turning point of the graph
Finding the x-coordinate of the turning point of a quadratic equation requires knowledge of its coefficients. Given a function y = x^2 + bx + c, and points (2,0) and (0,14), we need further calculations or information to precisely identify b to use the vertex formula -b/2a effectively.
Explanation:To find the x-coordinate of the turning point of the graph of the quadratic equation y = x^2 + bx + c, we can use the fact that the vertex of a parabola given by the general form ax^2 + bx + c is at x = -b/2a. Since the quadratic intersects the x-axis at (2,0), we can plug x = 2 into the equation to find one relation between b and c.
Another given point is (0,14), which when plugged in gives c = 14. To find b, we need more information from the question or an understanding of quadratic functions more deeply. However, without b, we can use the vertex formula derivatively, knowing that a in our equation is 1 (since the coefficient of x^2 is 1).
We also know that for any quadratic function, the x-coordinate of the vertex (turning point) can be found using -b/2a. Without the exact value of b, we cannot find the exact x-coordinate directly from the information given.
However, the general methodology would involve using the known points to first find equation coefficients and then apply the vertex formula. This highlights the importance of understanding quadratic functions and their graphical representations, such as vertices and intercepts, to solve these types of problems efficiently.
The x-coordinate of the turning point of the graph is 4.5
How to determine the x-coordinate of the turning point of the graph
From the question, we have the following parameters that can be used in our computation:
[tex]y = x^2 + bx + c[/tex]
It intersects the y-axis at (0, 14)
This means that
[tex]0^2 + b(0) + c = 14[/tex]
c = 14
So, we have
[tex]y = x^2 + bx + 14[/tex]
It intersects the x-axis at (2, 0)
So, we have
[tex]2^2 + 2b + 14 = 0[/tex]
4 + 2b + 14 = 0
2b = -18
b = -9
So, we have
[tex]y = x^2 - 9x + 14[/tex]
The x-coordinate of the turning point of the graph is then calculated as
x = -b/2a
So, we have
x = 9/2
x = 4.5
Hence, the x-coordinate of the turning point of the graph is 4.5
