The soccer club has planned a trip to a tournament. The cost of the van is
$231. When 3 students who are not members of the club join the trip, the
transportation cost per person drops by $4.50. How many soccer club
members are going to the tournament?
A. 14
B. 11
C. -14
D. -14, 11
Answer: B: 11
Step-by-step explanation:
Just to the quiz for it
An equation is formed of two equal expressions. The number of players going to the tournament is 11.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Since the cost of the van is fixed, therefore, 231. Thus, the two equations can be written as,
P × x = 231(P-4.50)×(x+3)=231Solving the above two equations we will get,
Px + 3P - 4.50x -13.5 = 231
3P - 4.50x - 13.5 = 0
3P - 4.50x = 13.5
3(231/x) - (4.50x) = 13.5
693 - 4.50x² = 13.5x
-4.50x² - 13.5x + 693 = 0
x² + 3x - 154 = 0
x = -14, 11
Since the number of members can not be negative, the number of players going to the tournament is 11.

There are 12 rolls of film in a box, and 4 are defective. Two rolls are to be selected, one after the other, sampling without replacement. What is the probability of selecting two defective rolls?
Group of answer choices
None of the answers is correct.
7/23
12/132
16/144
1/4
12/144
Using the hypergeometric distribution, it is found that the probability is 12/132
------------------------------------
The rolls are chosen from a sample without replacement, which means that the hypergeometric distribution is used to solve this question.
------------------------------------
Hypergeometric distribution:
The probability of x successes is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of successes.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
------------------------------------
12 rolls means that [tex]N = 12[/tex]4 defective means that [tex]k = 4[/tex]2 are chosen, which means that [tex]n = 2[/tex]------------------------------------
What is the probability of selecting two defective rolls?
This is P(X = 2). So
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 2) = h(2,12,2,4) = \frac{C_{4,2}*C_{8,0}}{C_{12,2}} = \frac{4 \times 3}{12 \times 11} = \frac{12}{132}[/tex]
12/132 is the probability.

Amelia's family took a road trip to Niagara Falls. Amelia fell asleep after they had travelled 931 miles. If the total length of the trip was 980 miles, what percentage of the total trip had they travelled when Amelia fell asleep?
Answer:
95%
Step-by-step explanation:
Total distance of trip = 980 miles
Miles covered when Amelia slept = 931 miles
what percentage of the total trip had they travelled when Amelia fell asleep?
Miles yet to be covered = 980 miles - 931 miles
= 49 miles
percentage of the total trip had they travelled when Amelia fell asleep = 931 / 980 × 100
= 0.95 * 100
= 95%
Answer:
95%

Jada and Priya are trying to solve the equation 2/3+x=4
Jada says, “I think we should multiply each side by 3/2 because that is the reciprocal of 2/3."
Priya says, “I think we should add -2/3 to each side because that is the opposite of 2/3."
1. Which person's strategy should they use?
2. Explain your reasoning.
Answer:
Priya is correct. Because 2/3 is being added to x and not multiplied, then subtracting 2/3 from both sides is the correct action.
Step-by-step explanation:
Let's run through solving it that way:
2/3 + x = 4
2/3 - 2/3 + x = 4 - 2/3
0 + x = 4 - 2/3
x = 4 - 2/3
x = 10/3

What are coordinates?A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.
The coordinates of a point are given as (x,y).
Now, the x-coordinate is on the horizontal axis, therefore, if the point is moving right it is going in the positive direction, while if the point is moving in the left direction it is going in the negative direction.
Similarly, the y-coordinate is on the vertical axis, therefore, if the point is moving upwards it is going in the positive direction, while if the point is moving in downwards its direction it is going in the negative direction.
Given that the coordinates are translated as 2 units left and 6 units up. Therefore, we can write,
(x,y) → (x-2, y+6)
Hence, the translation using translation notation can be described as
(x-2,y+6).
