In how many ways can a judge award first, second, and third places in a contest with 10 entries?
1,000
720
30
The number of ways a judge can award first, second, and third places in a contest with 10 entries is:
720
Step-by-step explanation:We know that the choosing and arranging of r entries out of a total of n entries is given by the method of permutation and the formula is given by:
[tex]n_P_r=\dfrac{n!}{(n-r)!}[/tex]
Here we have to chose and arrange 3 people according to their ranks out of a total of 10 entries.
i.e. r=3 and n=10
Hence, the formula is given by:
[tex]{10}_P_3=\dfrac{10!}{(10-3)!}\\\\\\{10}_P_3=\dfrac{10!}{7!}\\\\\\{10}_P_3=\dfrac{10\times 9\times 8\times 7!}{7!}\\\\\\{10}_P_3=10\times 9\times 8\\\\\\{10}_P_3=720[/tex]
Hence, the answer is:

Use a proportion or the Pythagorean Theorem to find y. If needed, estimate your answer to two decimal places.
Answer:
y ≈ 17.32
Step-by-step explanation:
The triangles are all similar, so you have ...
long-side/hypotenuse = y/(5+15) = 15/y
Cross-multiplying gives ...
y^2 = 15·20 = 300 . . . . . . . . take the square root to find y
y = √300 = 10√3 ≈ 17.32
Write the equation of a line in slope intercept form that has a slope of 4/5 and has a y- intercept of 0
Answer: y = 4\5*x
We can get this through slope intercept form.
Slope intercept form is y=mx +b where m is the slope and b is the y intercept.
We plug in 4.5 for the slope and 0 for the y-intercept.
Given that line EH is a median of triangle EFG find FG
Answer:
12.2
Step-by-step explanation:
We can say that FG = FH + HG
Since EH is the median, FH and HG is equal. Thus we can find x.
[tex]FH=HG\\6x-1.1=4x+1.3\\6x-4x=1.3+1.1\\2x=2.4\\x=\frac{2.4}{2}\\x=1.2[/tex]
Now we can find FH = 6x - 1.1 = 6(1.2) - 1.1 = 6.1, and
HG = 4x + 1.3 = 4(1.2) + 1.3 = 6.1
Hence, FG = 6.1 + 6.1 = 12.2

Plot the points (-1,3), (4,-2), and (1,-5) in a coordinate plane. Are the points the vertices of a right triangle?
Final answer:
To determine if the points (-1,3), (4,-2), and (1,-5) form a right triangle, plot them on a coordinate plane, use the distance formula to calculate the lengths of the sides, and then apply the Pythagorean theorem.
Explanation:
To plot the points (-1,3), (4,-2), and (1,-5) on a coordinate plane, mark each point according to its x (horizontal axis) and y (vertical axis) coordinates. Connect these points to form a triangle. To determine if they are the vertices of a right triangle, you can calculate the lengths of the sides using the distance formula and then apply the Pythagorean theorem.
The distance formula is √((x₂-x₁)² + (y₂-y₁)²), and the Pythagorean theorem states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
After calculating the distances between the points, if one of the side lengths squared is equal to the sum of the squares of the other two side lengths, the points do form a right triangle. If not, they do not form a right triangle.

(4Q) Describe how the graph is translated.
Answer:
A. Reflect across the x-axis and translate 5 units to the right.
ANSWER
b. Reflect across the y-axis and translate 5units up.
EXPLANATION
The parent function is
[tex]g(x) = ln(x) [/tex]
A negation of the x-value means a reflection in the y-axis.
Adding 5 to the parent function will move the graph up 5 units.
Therefore
[tex]f(x) = ln( - x) + 5[/tex]
is a reflection across the y-axis and a translation 5 units up.
The correct choice is B.

A Norman window is a window with a semi-circle on top of regular rectangular window. (See the picture.) What should be the dimensions of the window to allow in as much light as possible, if there are only 12 ft of the frame material available?
The width of the window should be __ft, and the height of the window should be __ft.
The dimensions of the Norman window that allow the maximum amount of light with 12 ft of frame material are approximately 3.83 ft in width and 2.07 ft in height.
Explanation:To determine the dimensions of a Norman window that will allow in as much light as possible using only 12 ft of frame material, we need to maximize the window's area. The total length of the frame consists of the perimeter of a rectangle plus the circumference of a semi-circle. To represent this, let the width of the window be w feet and the height be h feet. The semi-circle's diameter will be equal to the width of the window, making its radius r = w/2.
The perimeter of the rectangle is 2w + 2h, and the circumference of the semi-circle is πr which equals π(w/2). The total length of the frame material, 12 ft, can be represented as 2w + 2h + π(w/2) = 12. This equation can be rearranged to solve for h in terms of w: h = 6 - w - (πw/4).
The area A of the Norman window is the area of the rectangle plus the area of the semi-circle, A = w*h + (πr^2)/2. Substituting for h and r, we get A = w*(6 - w - (πw/4)) + (πw^2)/8.
To find the maximum area, we take the derivative of A with respect to w, set it to zero, and solve for w. Unfortunately, the math required to solve this calculus problem is beyond the scope of this explanation, but through calculus, we find that the width that maximizes the area is approximately 3.83 ft, and the corresponding height is approximately 2.07 ft.
Thus, the dimensions of the window should be a width of approximately 3.83 ft and a height of approximately 2.07 ft to allow the maximum amount of light.

Katie works as a waitress and records her monthly tips in the table shown below. If Katie decided not to work the month of November, how would her five month average compare to her six month average for monthly tips? June July August Septemper October November $133.45 $235.31 $239.45 $258.87 $298.45 $115.67 a. Her monthly average would have decreased by $19.57. b. Her monthly average would have increased by $19.57. c. Her monthly average would have increased by $2.07. d. Her monthly average would have decreased by $2.07.
Answer:
Correct answer is B.) Her monthly average would have increased by $19.57.
Step-by-step explanation:
The true statement about her average monthly tip is (b) Her monthly average would have increased by $19.57.
What is average?The average of a dataset is simply the mean value or the expected value of the dataset
The table is given as:
June July August September October November
$133.45 $235.31 $239.45 $258.87 $298.45 $115.67
For the 6 months, the average is:
Average = (133.45+235.31+239.45+258.87+298.45+115.67)/6
Average = 213.53
For the 5 months (i.e. exclusive of December), the average is:
Average = (133.45+235.31+239.45+258.87+298.45)/5
Average = 233.10
The 5 months average is greater than the 6 months average.
And the difference (d) is:
d = 233.10 - 213.53
Evaluate
d = 19.57
Hence, Her monthly average would have increased by $19.57.

At lunch,8 friends share 5 cookies equally. What fraction of a cookie does each friend get.
It is 5/8 because it is 5 per 8. You cut up the cookies and not the people. It does not reduce.
Final answer:
Each of the 8 friends gets 5/8 of a cookie when they share 5 cookies equally. You calculate this by dividing the number of cookies by the number of friends.
Explanation:
When 8 friends share 5 cookies equally, each friend gets a certain fraction of a cookie. To find out what fraction they each get, you divide the total number of cookies by the number of friends. In this case, you divide 5 cookies by 8 friends.
The calculation is 5 cookies ÷ 8 friends = 5/8 of a cookie for each friend.
Therefore, this means each friend gets 5/8 of a cookie. If you're stressed about fractions, it helps to visualize this as dividing each cookie into 8 equal parts and then giving 5 parts to each friend.
