Answer:
286 students attended
148 non students attended
Step-by-step explanation:
Given
[tex]Tickets = 434[/tex]
[tex]Students = \$4.00[/tex]
[tex]Non-Students = \$6.00[/tex]
[tex]Total = \$2032.00[/tex]
Solving (a): Number of students
Represent students with S and non students with N
So:
[tex]S + N = 434[/tex] --- (1)
[tex]4S + 6N = 2032[/tex] --- (2)
Make N the subject of formula in (1)
[tex]N = 434 - S[/tex]
Substitute 434 - S for N in (2)
[tex]4S +6(434 - S) = 2032[/tex]
Open Bracket
[tex]4S + 2604 - 6S = 2032[/tex]
Collect Like Terms
[tex]4S - 6S = 2032 - 2604[/tex]
[tex]-2S = -572[/tex]
Divide through by -2
[tex]S = 286[/tex]
Hence; 286 students attended
Solving (b):
Recall that
[tex]N = 434 - S[/tex]
[tex]N = 434 - 286[/tex]
[tex]N = 148[/tex]

BAKED GOODS Mary sells giant chocolate chip and peanut butter cookies for
$1.25 and $1.00, respectively, at a local bake shop. She wants to make at least
$25 a day
a. Write and graph an inequality that represents the number of cookies Mary
needs to sell each day.
Answer:
(1.25c) + (1p) ≥ 25
c is the amount of chocolate chip cookies
p is the amount of peanut butter cookies
Inequalities help us to compare two unequal expressions. The inequality that represents the number of cookies Mary needs to sell each day is 1.25x + 1y ≥ 25.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.
Let the number of chocolate chips sold be represented by x, while the number of peanut butter cookies is represented by y.
Given that the selling cost of chocolate chips and peanut butter cookies is $1.25 and $1.00, respectively. Also, Mary needs to make $25 a day, therefore, the inequality can be written in the form as,
1.25x + 1y ≥ 25
Hence, the inequality that represents the number of cookies Mary needs to sell each day is 1.25x + 1y ≥ 25.

What is the distance between (2,8) and (7,7)
Answer:
5.1 units
Step-by-step explanation:
Hey there!
To find the distance of points,
(2,8) and (7,7).
We need to use the Pythagorean Theurom formula which is,
[tex]a^2 + b^2 = c^2[/tex]
So we need to find the rise/run or a and b to find c or the distance.
x - 2 and 7, distance of 5 units
y - 8 and 7, distance of 1 unit.
Plug those numbers in.
[tex]5^2 + 1^2 = c^2[/tex]
25 + 1 = c^2
26 = c^2
c = 5.09901
c = 5.1 rounded to the nearest tenth.

In the class election, the student who gets the highest number of votes will become the class president and the one who gets the second highest
number of votes will become the class vice president. Tabitha and four other students were candidates. Tabitha's teacher announces the election
results as percentages of the total number of votes. Two hundred votes were cast in the election. In this activity, you will relate the percentages of
the votes received to the actual numbers.
Question 1
The table gives the percentage of votes each candidate received. Use the information in the table to understand the results of the election
Candidate Percentage of Votes
Tabitha
30%
Vincent
12%
Esmeralda
22%
Nancy
5%
Tyler
31%
Part A
How many votes did Tabitha receive?
Answer:
Tabitha received 60 votes.
Step-by-step explanation:
200 votes × .30 = 60 votes
The given percentage of votes shows that Tyler win the class elections (has the highest percentage of votes - 31%), and Tabitha received 60 votes (30% of 200).
What are percentages?A percentage is a fraction of a whole number represented as a number out of 100.
How do we solve the given question?We are given the percentages of votes received by the candidates in a class election. We are also informed that a total of 200 votes were cast in the elections.
The percentages are as follows:
Tabitha = 30%
Vincent = 12%
Esmeralda = 22%
Nancy = 5%
Tyler = 31%.
We are asked to find the winner of the election and the number of votes Tabitha received.
As Tyler receives the highest percentage of votes (31%), he is the winner of the elections.
Tabitha received 30% of the votes, and the total number of votes = 200
∴ Number of votes Tabitha received = 30% of 200 = (30/100)*200 = 0.3*200 = 6.
∴ Tabitha received a total of 60 votes.

The distribution of IQ (Intelligence Quotient) is approximately normal in shape with a mean of 100 and a standard deviation of 13. According to the standard deviation rule, only (what?) % of people have an IQ over 126.
Answer: 2.5% of people have an IQ over 126.
Step-by-step explanation:
Given: The distribution of IQ (Intelligence Quotient) is approximately normal in shape with a mean of 100 and a standard deviation of 13.
126 = 100 + 2(13) = Mean +2 ( standard deviation)
To find : % of people have an IQ over 126.
i.e. % of people have an IQ over Mean +2 ( standard deviation).
According to the standard deviation rule,
95% of data fall within two standard deviations.
Now, 100% - 95% = 5%
and Half of 5% is 2.5%.
So 2.5% of the data lies below 2 standard deviations of mean and 2.5% of the data lies above 2 standard deviations of mean .
i.e. 2.5% of people have an IQ over 126.

A light phone company advertises that its light bulb will last 100 hours. if 92% of the bulbs the company produces actually last that long. approximately how many light bulbs should be produced to have 15000 light bulbs meet the advertising claim?
Answer:
16,304
Step-by-step explanation:
We need to have a number that has 15,000 be 92% of it. To do this, divide 15,000 by 92% to find the total needed.
92% = 0.92
15,000/0.92 = 16,304.3 = 16,304
You will need 16,304 light bulbs.
A company should produce 16,304 bulbs to have 15,000 light bulbs meet the advertising claim.
The percentage formula:"For a number x, m% of number x is [tex]=x\times \frac{m}{100}[/tex] "
For given question,
Let 'n' represents the number of bulbs that should be produced to have 15000 light bulbs meet the advertising claim.
This means 92% of 'n' light bulbs should be 15000 light bulbs.
⇒ 15000 = n × (92/100)
⇒ 15000 = n × 0.92
⇒ n = (15000) / (0.92)
⇒ n = 16304.3
⇒ n ≈ 16304
Therefore, there should be 16304 light bulbs.

On average, which country user's spend the most time on social media? Which country's users spend the least time?
Answer:
Israel top, canada bottom
Step-by-step explanation:
Don't worry, I have this question too :)
Answer:
On average, Israel's country's users spend the most time on social media. United States' country's users spend the least time.
Step-by-step explanation:
Using the given inputs, we will rewrite these as decimals.
The only fractions that are listed are:
United States - 7 3/5
Canada - 7 7/10
Russia - 10 2/5
Colombia - 8 1/2
To convert a fraction to a decimal, we have to divide the numerator to the denominator. Add this decimal number to the whole number part of the mixed number.
So now, we get:
United States - 7.60
Canada - 7.70
Russia - 10.40
Colombia - 8.50
To determine which ones are greater than the others, you add a 0 to the end of the decimal.
The number with the least value here is 7.6, and the number with the largest value is 10.4. So, Israel's country's users spend the most time on social media. United State's country's users spend the least time on social media.
