A radio station runs a promotion at an auto show with a money box with 13 $50 tickets, 11$25 tickets, and 11$5 tickets. The box contains an additional 20 "dummy" tickets with no value. Three tickets are randomly drawn. Find the probability that exactly two $50 prizes and no other money winners are chosen
The probability of choosing exactly two $50 tickets and no other money winners is:
34,320 / 21,455 ≈ 0.
we can use the hypergeometric probability distribution to solve this problem, since we are drawing without replacement from a finite population of tickets with different values.
the total number of tickets in the box is:
13 + 11 + 11 + 20 = 55
the number of ways to choose exactly two $50 tickets from the 13 available is:
${13 \choose 2} = 78$
the number of ways to choose one dummy ticket from the 20 available is:
${20 \choose 1} = 20$
the number of ways to choose one ticket from the remaining non-$50 tickets is:
11 + 11 = 22
, the total number of ways to choose exactly two $50 tickets and no other money winners is:
78 x 20 x 22 = 34,320
the number of ways to choose any three tickets from the 55 available is:
${55 \choose 3} = 21,455$ 60 or about 60%

y varies jointly as the square of x, the square of z, and when x = 3 and
z = 4, then y = 72
What’s the equation?
The equation will be y = kx²z², where k is the proportionality constant.
Given that y varies jointly as the square of x, the square of z,
And when x = 3 and z = 4, then y = 72,
So, we can write,
y ∝ x²z²
or,
y = kx²z² [k = proportionality constant]
Now, given x = 3 and z = 4, then y = 72,
Therefore,
72 = 3²·4²·k
72 = 9·16 k
k = 72 / 144
k = 0.5
Therefore, the value of proportionality constant k is 0.5.
Hence the equation will be y = kx²z², where k is the proportionality constant.

A golfer played 7 rounds of golf with the following scores: 1 round at 3 over par, 2 rounds with 1 over par, 3 rounds with 3 under par, and the last round at 1 under par. How did she finish with respect to par?
Answer:
To determine how the golfer ended in terms of par, tally up all of her scores and deduct them from the total par for the seven rounds.
The total par for seven rounds multiply by eighteen is 126 (assuming the course is a regular par 72).
The golfer's score in relation to par for each round is:
1 round at 3 over par = 75 (72 + 3)
2 rounds with 1 over par = 73 (72 + 1) x 2 = 146
3 rounds with 3 under par = 69 (72 - 3) x 3 = 207
1 round at 1 under par = 71 (72 - 1)
you add all the pars working above, which is
75 + 146 + 207 + 71 = 499
Her score of 499 is 27 below par (126 - 499 = -373), meaning she ended significantly below par.

The utilization factor can be calculated as the ratio of the arrival rate to the service rate. In this case, the arrival rate (lambda) is 15 per hour, and the service rate (mu) is 25 per hour. Therefore, it is important for the clinic to monitor the utilization factor and adjust staffing levels as needed to ensure efficient and effective patient communication.
So the utilization factor is:
Utilization factor = lambda / mu
Utilization factor = 15 / 25
Utilization factor = 0.6
This means that on average, the operator is utilized 60% of the time. In other words, there is a 40% idle time during which no phone calls are being processed. This is a relatively low utilization factor, which suggests that there is some capacity to handle more phone calls if necessary. However, it is important to note that if the arrival rate were to increase, the utilization factor would increase as well, which could lead to longer wait times for patients and potential bottlenecks in the phone system.

two people leave their shared apartment at the same time. during a 500 second interval, one jogs 10 blocks south at a constant rate, whereas the second walks 5 blocks west, again, at a constant rate. what is their speed relative to each other during this interval? assume each block corresponds to 100 meters.
The relative speed between the jogger and the walker during the 500 second interval is 2.24 m/s.
To solve this problem, we need to first find the distances traveled by each person.
The jogger travels 10 blocks x 100 meters/block = 1000 meters south.
The walker travels 5 blocks x 100 meters/block = 500 meters west.
Using the Pythagorean theorem, we can find the distance between them: √((1000m)² + (500m)²) = 1118.03 meters.
To find their relative speed, we divide this distance by the time interval: 1118.03 meters / 500 seconds = 2.24 m/s.
Therefore, their speed relative to each other during this interval is 2.24 m/s.
The jogger traveled 1000 meters south, while the walker traveled 500 meters west. Using the Pythagorean theorem, the distance between them is 1118.03 meters. Dividing this distance by the time interval of 500 seconds, we get their relative speed, which is 2.24 m/s.

Calculate the length of AC to 1 decimal place
The length of AC by the given data is about 11.0 cm.
We are given that;
ABCD is a trapezium AB=16cm, AD=11cm, BC=4cm
Now,
We can use these values to find DC. Since ABCD is a trapezium, we know that AB and DC are parallel. Therefore, the distance between them is constant. We can write:
AB−BC=AD−DC
Plugging in the given values, we get:
16−4=11−DC
Solving for DC, we get:
DC=11−12=−1
We can ignore the negative sign since we are only interested in the length of DC. So, DC = 1 cm.
Now we can plug in AD = 11 cm and DC = 1 cm into the Pythagorean theorem and get:
AC2=112+12
AC2=122
Taking the square root of both sides, we get:
AC=122≈11.045
Rounding to one decimal place, we get:
AC≈11.0 cm
Therefore, by algebra the answer will be 11.0 cm.

x^4-5x^3+7x^2-5x+6=0
Answer:Therefore, the solutions to the equation x^4 - 5x^3 + 7x^2 - 5x + 6 = 0 are x = 0, x = 1, x = 5.
Step-by-step explanation:
To solve the equation x^4 - 5x^3 + 7x^2 - 5x + 6 = 0, we can use factoring by grouping.
First, we can group the first two and last two terms:
x^4 - 5x^3 + 7x^2 - 5x + 6 = (x^4 - 5x^3) + (7x^2 - 5x + 6)
Next, we can factor out x^3 from the first group and factor out 1 from the second group:
(x^3(x - 5)) + (7x^2 - 5x + 6)
Now, we can group the last two terms of the second group:
x^3(x - 5) + (7x^2 - 3x - 2x + 6)
Then, we can factor out 1 from the terms inside the parentheses and group them:
x^3(x - 5) + (7x^2 - 3x) + (-2x + 6)
Now, we can factor out x from the second and third groups:
x^3(x - 5) + x(7x - 3) - 2( x - 3)
We can simplify the third group by distributing the negative sign:
x^3(x - 5) + x(7x - 3) - 2x + 6
Finally, we can combine the second and third groups:
x^3(x - 5) + x(7x - 5) + 6
So, the factored form of the equation x^4 - 5x^3 + 7x^2 - 5x + 6 = 0 is:
(x^3(x - 5) + x(7x - 5) + 6) = 0
This equation can be solved by setting each factor equal to zero and solving for x:
x^3(x - 5) + x(7x - 5) + 6 = 0
(x^3 - 7x^2 + 5x) + (6 - 5x) = 0
x(x^2 - 7x + 5) - (5x - 6) = 0
x(x - 5)(x - 1) - (5x - 6) = 0
x(x - 5)(x - 1) = 5x - 6
x^3 - 6x^2 + 10x - 6 = 5x - 6
x^3 - 6x^2 + 5x = 0
x(x^2 - 6x + 5) = 0
x(x - 1)(x - 5) = 0
Therefore, the solutions to the equation x^4 - 5x^3 + 7x^2 - 5x + 6 = 0 are x = 0, x = 1, x = 5.

The correct statement is:
As x → ∞, f(x) → ∞ and as x → -∞, f(x) → -∞.
I understand that you are asking about the behavior of the function g(z) as x approaches positive and negative infinity. Let's analyze the given function:
g(z) = 4x³ - 3r + 2r³ - 1
First, I believe "r" should be "x" to keep the variables consistent. So, the corrected function is:
g(x) = 4x³ - 3x + 2x³ - 1
Now, let's find the end behavior of this function as x approaches positive and negative infinity.
As x → ∞:
The highest degree term, x³, will dominate the function's behavior. The coefficients for x³ are 4 and 2, so the function will behave like 6x³. Since this term is positive and has an odd exponent, as x → ∞, f(x) → ∞.
As x → -∞:
Again, the x³ term will dominate the function's behavior. Since the exponent is odd, as x → -∞, f(x) → -∞.
So, the correct statement is:
As x → ∞, f(x) → ∞ and as x → -∞, f(x) → -∞.

Find the volume of liquid needed to fill a sphere of radius R to height R/5.
To find the volume of liquid needed to fill a sphere of radius R to a height of R/5, we can consider the spherical cap formed by the liquid.
The volume of a spherical cap can be calculated using the formula:
V = (1/3)πh²(3R - h)
Where V is the volume, h is the height of the cap, and R is the radius of the sphere.
In this case, the height of the cap is R/5 and the radius of the sphere is R. Substituting these values into the formula, we get:
V = (1/3)π(R/5)²(3R - R/5)
= (1/3)π(R²/25)(15R - R/5)
= (1/3)π(R²/25)(74R/5)
= (74/75)πR³

To obtain a mixture of coffee that can be sold for $60 a pound, the merchant must mix the $20 coffee with the $80 coffee in such a way that the resulting mixture is worth $60 per pound.
To determine how many pounds of the $20 coffee should be used, we can set up a system of equations using the weights of each type of coffee and their corresponding values per pound.
Let x be the number of pounds of the $20 coffee to be used. Then, the total weight of the mixture is 80 + x pounds. The value of the $20 coffee is $20 per pound, and the value of the $80 coffee is $80 per pound. The value of the mixture must be $60 per pound. Therefore, we can write the following equation:
$20x + 80(80) = 60(80 + x)$
Simplifying and solving for x, we get:
$x = 200$
Therefore, the merchant should use 200 pounds of the $20 coffee and mix it with 80 pounds of the $80 coffee to obtain a mixture that can be sold for $60 a pound.

The equation of the line represented by the points on the graph is (5x+16)/6.
What is a line?line is a straight one-dimensional figure that does not have a thickness, and it extends endlessly in both directions.
To calculate the equation of the line represented by the points on the graph, we use the formula below
Formula:
(y-y₁)/(x-x₁) = (y₂-y₁)/(x₂-x₁)....................... Equation 1From the points in the graph,
Given:
y₁ = 1y₂ = 6x₁ = -2x₂ = 4Substitute these values into equation 1
[y-1]/[x-(-2)] = (6-1)/[4-(-2)]y-1/x+2 = 5/66(y-1) = 5(x+2)6y-6 = 5x+106y = 5x+10+66y = 5x+16y = (5x+16)/6Learn more about lines here: https://brainly.com/question/29044610
