Zoo admission costs $6 for children and $9 for adults. On Monday, 2200 people visit the zoo and the zoo collects $14,850 in admissions.
a. Write a system of linear equations that represents this situation. Let x represent the cost of a ticket for a child and let y represent the cost of a ticket for an adult.
System of equations:
Answer:
There are 1650 child visitors and 550 adult visitors
Step-by-step explanation:
Use this step by step that was already used before to answer this, it's a png file.
A system of linear equations that represents this situation is,
⇒ x + y = 2200
⇒ 6x + 9y = 14,850
Where, x represent the cost of a ticket for a child and let y represent the cost of a ticket for an adult.
What is linear expression?A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
Zoo admission costs $6 for children and $9 for adults.
And, On Monday, 2200 people visit the zoo and the zoo collects $14,850 in admissions.
Let x represent the cost of a ticket for a child and let y represent the cost of a ticket for an adult.
Hence, We can formulate;
A system of linear equations that represents this situation is,
On Monday, 2200 people visit the zoo.
So, we get;
⇒ x + y = 2200 .. (i)
And, Zoo admission costs $6 for children and $9 for adults and the zoo collects $14,850 in admissions.
So, We get;
⇒ 6x + 9y = 14,850 .. (ii)

Which compares the medians of the data?
The median for the students is 4 and the median for the teachers is 8.
The median for the students is 2 and the median for the teachers is 3.
The median for the students is 4 and the median for the teachers is 3.
The median for the students is 2 and the median for the teachers is 8.
Answer: The median for the students is 2 and the median for the teachers is 3.
Step-by-step explanation:
Ordering the data for the students from the dot points:
0, 0, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4.
n = 20 which is positive so median position is average of:
= (n / 2) and = (n + 1) / 2
= 20 / 2 = 21 / 2
= 10 = 10.5
2 is in position 10 2 is in position 10.5
Average = (2 + 2) / 2 = 2
Student median is 2.
Teachers
0, 1, 1, 1, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 6, 8
3 is in position 10 as well as in position 10.5.
= (3 + 3) / 2
= 3

\250 doctors from three countries in Europe meeting in a conference to decide whether to approve a new vaccine for the flu. Among these are 115 Germans, 65 French, and 70 Englishmen. We also know that, 75% of the Germans, 60% of the French and 65% of the Englishmen are in favor of using the new vaccine. (a) What is the probability that a randomly chosen doctor is in favor of the vaccine
Answer:
0.683 = 68.3% probability that a randomly chosen doctor is in favor of the vaccine
Step-by-step explanation:
(a) What is the probability that a randomly chosen doctor is in favor of the vaccine
75% of 115/250 = 0.46(German).
60% of 65/250 = 0.26(French).
65% of 70/250 = 0.28(Englishmen). So
[tex]p = 0.75*0.46 + 0.6*0.26 + 0.65*0.28 = 0.683[/tex]
0.683 = 68.3% probability that a randomly chosen doctor is in favor of the vaccine

232. Сколько решений имеет уравнение | х + 3 | -один?
Answer: уравнение имеет 2 решения:
x₁ = - 4; x₂ = - 2.
Step-by-step explanation:
Ix + 3I = 1
1) x + 3 = 1
x + 3 - 3 = 1 - 3
x = -2
2) - (x + 3) = 1
x + 3 = - 1
x + 3 - 3 = - 1 - 3
x = - 4

Study the data set shown. Then answer the questions below.
a. Any number that is not the minimum or maximum could be removed without changing the range.
b. Removing the number 97 changes the range.
What is set ?
In mathematics, a set is a collection of distinct objects, called elements or members, that are treated as a single entity. Sets can contain any type of object, such as numbers, letters, or other mathematical objects.
To find a number that could be removed from the data set without changing the range, we need to determine the minimum and maximum values in the set. In this case, the minimum value is 53 and the maximum value is 97, so any number that is not the minimum or maximum could be removed without changing the range. For example, we could remove the number 85:
53 54 63 63
68 68 68 74
82 85 92 88
89 92 92 97
The range of the data set is still 97 - 53 = 44.
To find a number that could be removed from the data set that would change the range, we need to identify a number that is either the minimum or maximum value. For example, we could remove the number 97:
53 54 63 63
68 68 68 74
82 85 85 88
89 92 92
b. The range of the data set is now 92 - 53 = 39, which is smaller than the original range of 44.
Therefore, removing the number 97 changes the range.
