at a local play student tickets cost $5 each and adult tickets cost $11 each if tickets sales were 3000 for 300 tickets how many students attended the play
Answers
Answer: 50 students attended the play.
Step-by-step explanation:
Let x be the number of student tickets sold and y be the number of adult tickets sold. We know that:
x + y = 300 (total number of tickets sold)
5x + 11y = 3000 (total revenue from ticket sales)
We can use the first equation to solve for one of the variables in terms of the other. For example, we can substitute y = 300 - x into the second equation:
5x + 11(300 - x) = 3000
5x + 3300 - 11x = 3000
-6x = -300
x = 50
Huey can wash 6 cars or mow 3 lawns in one hour. Dewey can wash 3 cars or mow 3 lawns in one hour. Louie can wash 3 cars or mow 6 lawns in one hour. They each work 8 hours per day. If two of them wash cars and one mows lawns then at most they can wash cars and mow lawns. Enter whole numbers.
Answers
At most, they can wash 96 cars and mow 96 lawns.
To determine the maximum number of cars they can wash and lawns they can mow, we need to consider the work rates of each person and the total number of hours they work.
Huey can wash 6 cars or mow 3 lawns in one hour, so in 8 hours, he can wash 6 \(\times\) 8 = 48 cars or mow 3 \(\times\) 8 = 24 lawns.
Dewey can wash 3 cars or mow 3 lawns in one hour, so in 8 hours, he can wash 3 \(\times\) 8 = 24 cars or mow 3 \(\times\) 8 = 24 lawns.
Louie can wash 3 cars or mow 6 lawns in one hour, so in 8 hours, he can wash 3 \(\times\) 8 = 24 cars or mow 6 \(\times\) 8 = 48 lawns.
Since two of them wash cars and one mows lawns, the maximum number of cars they can wash is the sum of the maximum cars each person can wash, which is 48 + 24 + 24 = 96 cars.
The maximum number of lawns they can mow is the sum of the maximum lawns each person can mow, which is 24 + 24 + 48 = 96 lawns.

The formula of rational function is \(R(x) = \frac{P(x)}{Q(x)}\) , where P(x) and Q(x) are polynomial functions.
What is rational function ?
A rational function is one that can be written as a polynomial divided by a polynomial. Since polynomials are defined everywhere, the domain of a rational function is the set of all numbers except the zeros of the denominator. Example 1. f(x) = \(\frac{x}{x - 2}\).
Rational functions are typically identified by the degrees of the numerator and denominator. For example, a quadratic for the numerator and a cubic for the denominator is identified as a quadratic/cubic rational function. A rational function model is a generalization of the polynomial model.

The values for the highlighted variables is a=-1,b=-9,c=9,d=3,e=3,f=2 and g=3/2.
Given:
3x/2x-6 + 9/6-2x
Rewrite 6-2x as 2x-6 by taking (-1) as common factor:
= 3x/2x-6 + 9/(-1)(2x-6)
so a = -1
= 3x/2x+6 + -9/2x-6
so b = -9
The LCM of 2x - 6 and 2x - 6 is 2x -6.
= 1*3x + 1*-9 / 2x-6
= 3x - 9 / 2x -6
so c = 9
(3x - 9) = 3(x-3)

Answer:

Step-by-step explanation:
The items below are based on the following scenario.
A counseling psychologist developing a technique to reduce procrastination has students time their procrastination for a week and uses this as a pretest measure of procrastination. Students then attend a workshop in which they are instructed to do a specific warm-up exerdse for studying by focusing on a pleasant activity. Students again time their procrastination for a week, and the time from this second week is the posttest measure.
1. If the psychologist wants to see if there is a change (increase or decrease) in procrastination by students who attended his workshop, the appropriate description of "Population 2" (the comparison population) would be people whose:_________.
a. posttest scores will be lower than their pretest scores.
b. difference scores will be 0 or greater than 0.
c. difference scores will be 0.
d. difference scores will be smaller than their pretest scores.
2. If the psychologist wants to see if there is a change (increase or decrease) in procrastination by 10 of the students who attended his workshop using the.05 significance level, the cutoff t score(s) would be:_______.
a. -.62,0,0,+2.62
b. +2.262
c. -2.262,0
d. -2.262, +2.262
3. If the psychologist finds that the sum of squared deviations from the mean of the difference scores of the sample is 135, the estimated population variance would be:__________.
a. 135/10 = 13.5
b. 135/9 = 15.0
c. 10/135 =.074
d. 9/135 =.067
Answers
Answer:
1) Option C is correct.
Difference should be 0.
2) Option D is correct.
The cutoff t-scores are -2.262, 2.262.
t < -2.262, t > 2.262
3) Option A is correct.
The variance = (135/10) = 13.5
Step-by-step explanation:
1) For any hypothesis test, the first step is usually to define the null and alternative hypothesis.
In hypothesis testing, especially one comparing two sets of data, the null hypothesis plays the devil's advocate and usually takes the form of the opposite of the theory to be tested. It usually contains the signs =, ≤ and ≥ depending on the directions of the test. It usually maintains that, with random chance responsible for the outcome or results of any experimental study/hypothesis testing, its statement is true.
The alternative hypothesis usually confirms the theory being tested by the experimental setup. It usually contains the signs ≠, < and > depending on the directions of the test. It usually maintains that significant factors other than random chance, affect the outcome or results of the experimental study/hypothesis testing and result in its own statement.
For this test, the counselling psychologist wants to check if there is a difference, whether positive or negative between the procrastination times before and after attending the workshop.
So, the appropriate parameter to compute would be the difference in procrastination times before and after the workshop.
Then the null hypothesis would be that the difference between these two times is 0.
Alternative hypothesis would be that there is no difference between the two times.
Mathematically, if the difference between the two times is p.
The null hypothesis is represented as
H₀: p = 0
The alternative hypothesis is represented as
Hₐ: p ≠ 0
Hence, it is evident that the comparison population would be the difference scores being 0.
b) This test aims to test whether there's a negative or positive difference in the scores before and after the workshop.
So, the test will be in both directions. The cut off t-score indicating the rejection regions would be found using the significance level provided (0.05) and the degree of freedom.
degree of freedom = df = n - 1 = 10 - 1 = 9
t(9, 0.05) = ± 2.2622 (from the t-distribution tables)
c) Variance is an average of the squared deviations from the mean.
Mathematically, estimate of the population variance is given as
Variance = σ² = [Σ(x - xbar)²/N]
Where Σ(x - xbar)² = square of the deviations from the mean = 135
N = Sample Size = 135
So, variance = (135/10) = 13.5

Answers
The circumference of 1/8th of a circle with a radius of 30 centimeters is 11.78 centimeters.
The formula for the circumference of a circle is C = 2πr, where C is the circumference, π is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.
To find the circumference of 1/8th of a circle, we need to divide the circumference of the full circle by 8. So, the formula becomes:
C = (1/8) * 2πr
Substituting the given value of the radius, we get:
C = (1/8) * 2π(30)
Simplifying, we get:
C = (1/4) * π(30)
C = (1/4) * 30π
C = 7.5π
Approximating π as 3.14, we get:
C = 7.5 * 3.14
C = 23.55/2
C = 11.78
Therefore, the circumference of 1/8th of a circle with a radius of 30 centimeters is 11.78 centimeters.

In a shop, the cost of 4 shirts, 4 pairs of trousers and 2 hats are $560. The cost of 9 shirts, 9 pairs of trousers and 6 hats is $1,290. What is the total cost of 1 shirt, 1 pair of trousers and 1 hat?
Answers
Answer: Given:
4 shirts, 4 pairs of trousers , and 2 hats is $560
9 shirts, 9 pairs of trousers , and 6 hats is $1,290
1) Let x be the price of 1 shirt
Let y be the price of 1 pair of trousers
Let z be the price of 1 hat
2) 4x + 4y + 2z = 560
3) 9x + 9y + 6z = 1,290
4) (9x + 9y + 6z) / 3 = 1,290 / 3
3x + 3y + 2z = 430
5)
4x + 4y + 2z = 560
- (3x + 3y + 2z = 430)
x + y = 130
6) 3(x+y) + 2z = 430
3(130) + 2z = 430
390 + 2z = 430
2z = 430 - 390
2z = 40
z = 40/2
z = 20
7) x = price of 1 shirt; y = price of 1 pair of trousers ; z = price of 1hat
x + y = 130 ; z = 20
130 + 20 = 150
The price of 1 shirt, 1 pair of trousers, and 1 hat is $150.

(c) The cost of a 9 1/2 minute call is 1.66 (m > 6; m is not an integer)
What is a piecewise function?A piecewise function is given by different functions at different intervals.
Calculation:It is given that,
phone company set the following rate schedule for an m-minute call from any of its pay phones.
C(m) = 0. 70 when m ≤ 6
= 0.70 + 0.24(m - 6) when m > 6 and m is an integer
= 0.70 + 0.24([m - 6] + 1) when m > 6 and m is not an integer
(a) The cost of a call that is under six minutes:
Since m < 6, the cost is C(m) = 0.76
Thus, the cost of a call that is under six minutes is 0.76
(b) The cost of a 14-minute call:
Since 14 > 6, the cost is C(m) = 0.70 + 0.24(m - 6) when m > 6 and m is an integer.
C(14) = 0.70 + 0.24(14 - 6)
= 0.70 + 0.24(8)
= 0.70 + 1.92
= 2.62
Thus, the cost of a 14-minute call is 2.62.
(c) The cost of a 9 1/2 minute call:
9 1/2 = 19/2 = 9.5
Since 9.5 > 6, the cost is C(m) = 0.70 + 0.24([m - 6] + 1) when m > 6 and m is not an integer.
C(9.5) = 0.70 + 0.24([9.5 - 6] + 1)
= 0.70 + 0.24([3.5] + 1)
Since we know that if [x] is a function then its domain is R and the range is Z(integer)
So, [3.5] = 3(is an integer)
Then,
C(9.5) = 0.70 + 0.24(3 + 1)
= 0.70 + 0.96
= 1.66
Therefore, the cost of a 9 1/2 minute call is 1.66.

\(a_n=4n-11\)
Step-by-step explanation:
The common difference is \(d=4\) with the first term being \(a_1=-7\), so we can generate an explicit formula for this arithmetic sequence:
\(a_n=a_1+(n-1)d\\a_n=-7+(n-1)(4)\\a_n=-7+4n-4\\a_n=4n-11\)
