Helena asked five drama club members in her homeroom how many tickets they had sold. The mean number of tickets sold was 16.
Then she took ten random samples from the entire drama club of 75 students. The mean number of tickets sold was 22.5.
Compare the means. Is one sample a better representation? Explain why or why not.
Using the Central Limit Theorem, considering the higher sample size, the sample of 75 students, with a mean of 22.5, is a better representation.
What does the Central Limit Theorem state?It states that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard error [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
A higher sample size leads to a smaller standard error, hence the sample of 75 students, with a mean of 22.5, is a better representation.

Answer:
This is my answer:The second one is better. the entire drama club one was better because the sample is large enough .It also comes from a bigger and more varied group of students thus it is less likely to be biased.

The sum of twice a number and three times a number is triple the quantity of five more than a number. Find the number.
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
First you have to translate the words to numbers into an understandable equation like this...
[tex]2x+3x=3(x+5)[/tex]
Now we can solve for x...
[tex]2x+3x=3(x+5)\\2x+3x=3x+15\\5x=3x+15\\2x=15\\x=7.5[/tex]
So the number is 7.5
5/2 is the number if the sum of twice a number and three times a number is triple the quantity of five more than a number then the number.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, The sum of twice a number and three times a number is triple the quantity of five more than a number.
Assuming the number has a unique multiple of x.

If the radius of a pizza has a length of
X + 5 units, what is the area of the
pizza? What is the value when x = 10
inches?
Answer:
225π inches²
Step-by-step explanation:
Assuming the pizza to be a circle, its area is calculated below:
[tex]A=\pi r^2\\A=\pi(x+5)^2\\A=\pi(10+5)^2\\A=\pi(15)^2\\A=225\pi[/tex]
Thus, the radius of the pizza is [tex]225\pi[/tex] inches² when x is 10 inches.
The tens digit of a three digit number exceeds its units digits by 3. If we were to swap the 100's digit and the unit's digit, the new number would be 297 more than the original number. If we were to remove the hundreds digit from the original number, the two digit number obtained would be 13 less than half the original number. What's the original number?
Answer: 174
Step-by-step explanation:
Let's define the notation:
U = units digit
T = tens digit
H = hundreds digit.
Where the number is HTU.
We know that:
T = U + 3
"UTH" - "HTU" = 297.
"TU" = "HTU"/2 - 13.
First, let's wrote this correctly, and make a system of equations:
T = U + 3.
U*100 + T*10 + H - H*100 - T*10 - U = (U - H)*99 = 297.
T*10 + U = (H*100 + T*10 + U)/2 - 13 = H*50 + T*5 + U*0.5 - 13
Then we have the system of equations:
T = U + 3.
(U - H)*99 = 297
T*10 + U = H*50 + T*5 + U*0.5 - 13.
First, we can replace the first equation into the third one, so now we have only two variables.
(U - H)*99 = 297
(U +3)*10 + U = H*50 + (U + 3)*5 + U*0.5 - 13.
Now we can isolate H in the first equation and get:
(U - H) = 297/99
H = -297/99 + U.
Now we can replace it into the other equation:
(U +3)*10 + U = (-297/99 + U)*50 + (U + 3)*5 + U*0.5 - 13.
Now let's solve this for U.
U*10 + 30 + U = U*50 -150 + 5*U + 15 + U*0.5 - 13
11*U + 30 = U*(50 + 5 + 0.5) - 148
30 +148 = U*(55.5 - 11) = U*44.5
U = 178/44.5 = 4.
Then using the previous equations:
T = U + 3 = 4 + 3 = 7
H = -3 + U = -3 + 4 = 1.
Then our number is:
174.

the pyramid is comprised of four triangles and one square, all we need is to find the individual surface areas of the shapes that compose the pyramid
Answer:
(a) see attached
(b) Surface area = 224 mm²
Step-by-step explanation:
A square based pyramid is made up of a square at the base and 4 congruent triangles as the sides which meet at one point.
Area of a triangle = 1/2 × base × height
⇒ area of one triangle = 1/2 × 8 × 10
= 40 mm²
Area of a square = s² (where s is the side length)
⇒ area of base = 8²
= 64 mm²
Total surface area = 4 × area of one triangle + area of the base
= 4 × 40 + 64
= 224 mm²

Amari can spend at most $40 at the fair. It cost her $12 to enter the fair and $3 per ticket, t, to ride the rides.
Answer:
i have no idea if you're looking for how many rides she can go on or the equation so i'll give you both lol.
Step-by-step explanation:
3t + 12 = 40
t represents the number of tickets (rides)
$12 is the entry fee.
$3 is the cost per ticket
to solve, use the subtraction property of equality. (subtract 12 from both sides)
3t + 12 - 12 = 40 - 12
3t = 28
divide each side by 3.
3t/3 = 28/3
28/3 = 9.3333...
amari can go on a maximum of 9 rides ($27) and stay within her budget of $40 or less.
$27 + $12 = $39.
she will have $1 left over.
The inequality in the given situation is 3t+12≤40
Given that, Amari can spend at most $40 at the fair.
What is inequality?Inequalities are mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Now, the cost her $12 to enter the fair and $3 per ticket, t, to ride the rides.
Here, $3 per ticket, t, to ride the rides = 3t
So, the inequality is 3t+12≤40
Therefore, the inequality in the given situation is 3t+12≤40.

Augment is 5 1/3 feet tall how many inches tall is she
Answer:
64 inches tall
Step-by-step explanation:
We know in 1 foot, there are 12 inches.
We can convert 5 1/3 feet to 16/3 feet.
To do this you convert 5 feet to 15/3 feet and add it to 1/3 feet.
So we now have 16/3 feet and we will multiply by 12 to find the number of inches she is.
16/3 * 12 = 64 inches tall

Rolling a 3 or rolling an odd number on a six sided die. Is it mutually exclusive or non-mutually exclusive? Give one reason.
Answer:
Non-mutually exclusive
Step-by-step explanation:
both events can happen simultaneously... 3 is an odd number, events A and B have a common outcome.
It would be mutually exclusive if event A was rolling a 4 and event B was rolling an odd number.
===================================================
Explanation:
Ask yourself "is it possible to get a 3 and an odd number at the same time?"
The answer is "yes, because 3 is an odd number"
This is why they are non-mutually exclusive.
Mutually exclusive events cannot happen at the same time. In terms of a venn diagram, mutually exclusive events would be represented by two circles that do not overlap. The overlapping region is where the two events happen at the same time. An example of mutually exclusive events would be flipping a single coin to land on heads and tails at the same time.
