Every year, the students at a school are given a musical aptitude test that rates them from 0 (no musical aptitude) to 5 (high musical aptitude). This year's results were:
The question is incomplete. Here is the complete question.
Every year, the students at a school are given a musical aptitude test that rates them from 0 (no musical aptitude) to 5 (high musical aptitude). This year's results were shown in the figure below.
The average (mean) aptitude score:
The median aptitude score:
Answer: mean: 2.73
median: 3
Step-by-step explanation: Mean is the average number of a set of numbers.
The table below shows a frequency of students to each score of the test. To calculate mean with a frequency table, do the following:
[tex]mean=\frac{\Sigma (score*frequency)}{\Sigma frequency}[/tex]
[tex]mean=\frac{0*1+1*5+2*0+3*3+4*3+5*3}{1+5+0+3+3+3}[/tex]
mean = 2.73
Median is the middle term of a set of data.
When there is a frequency table, median is calculated as:
1) First, determine the total number of observations (n).
For this table, n = 15
2) Because n is odd, find the position of the median using:
[tex]position=\frac{n+1}{2}[/tex]
position = 8th
3) The median will be in the 8th position. To find the position, we add the frequencies and in doing so, we notice the position we want is in the score 3 category. So, the median for this frequency table is 3.
Average score of a musical aptitude test is 2.73 and median is 3

Mary-Ann has $28, which is 2 1/3 as much money as Lola has. How much money does Lola have?
Answer:
$12
Step-by-step explanation:
Lola has x.
Mary-Ann has 2 1/3 times Lola's amount, so Mary-Ann has (2 1/3)x.
Mary-Ann has $28.
(2 1/3)x = 28
7/3 x = 28
Multiply both sides by 3/7.
x = 28 * 3/7
x = 12
Lola has $12.

Which of the following numbers are greater than 30 and less than the difference between 60 and 25?
Select all answers that apply:
A. 30
B. 32
C. 34
D. 36
E. 38
Answer:
B and C
Step-by-step explanation:
60-25= 35
So you have to pick the numbers between 30 and 35, but not 30 I believe.
The numbers greater than 30 and less than the difference between 60 and 26 were 32 & 34.
Step-by-step explanation:
Given:
Numbers : 30, 32, 34,36,38
To find:
The numbers greater than 30 and less than the difference between 60 and 25.
Solution:
30<N<(60-25)
30<N<35
Where:
N = Number greater than 30 and less than 45
Put, N=3030<30<35 ( not valid, 30 is equal to 30)
Put, N=3230<32<35 ( valid)
Put, N=3430<34<35 ( valid)
Put, N=3630<36<35 ( not valid, 36 is greater than 35)
Put, N=3830<38<35 (not valid,38 is greater than 35)
The numbers greater than 30 and less than the difference between 60 and 26 were 32 & 34.

Kacy is on her freshman basketball team. She makes 48% of her foul shots, leading her team to 14 wins in 17 games for the season.
If Kacy took 78 foul shots during the season, how many shots did she make?
Answer:
37 shots
Step-by-step explanation:
48% = 48/100
Set the ratios equal to each other so that we can find "x" the number of shots she made.
48/100 = x/78
78*48 = 3744
3744/100 = 37.44
She made 37 shots

For .5m^2: .6
For 12 liters of paint: 10m^2
and for 6.6: 5.5m^2
Answer:
a) 8.4
b) 0.6
Step-by-step explanation:
a) 1.2L=1m^2
8.4L = 7m^2
7 times 1.2 is 8.4
b) 1.2L=1m^2
0.6L=0.5m^2
1.2 times 0.5 or 1.2 divided by 2 is 0.6
You are interested in determining if the average amount of time (in hours) that students spend on the Internet per day is greater than 2 hours. The data below are from a random sample of 11 students. 2.5 100 .5 1 1.5 3 3.5 4 3 4 2.5 What did you notice from your preliminary analysis of the data
Answer:
The data is not appropriately normal.
Step-by-step explanation:
In inferential statistics, a normal distribution is said to be symmetric and should be single-peaked when working with a random selection of a large sample.
The high number of the sample is 100 which is further from other samples, the central limit theorem explains that the sample size of independent mean must be large enough to mimic the population for the sample to be normal or nearly normal. So, the sample is not appropriately normal and should be larger in size.

1. In order for cos 47 to equal sin A, what must the measure of angle A be?
Explanation:
The rule used here is
if sin(A) = cos(B), then A+B = 90.
In this case, B = 47, meaning that,
A+B = 90
A+47 = 90
A = 90-47
A = 43
Therefore,
sin(43) = cos(47)
WILL GIVE BRAINLIEST !!! What is the axis of symmetry for the function, f(x) = −2(x − 4)2 + 2 ?
Answer:
[tex]x=4[/tex]
Step-by-step explanation:
We have the function:
[tex]f(x)=-2(x-4)^2+2[/tex]
This is a quadratic in vertex form:
[tex]f(x)=a(x-h)^2+k[/tex]
Where (h, k) is the vertex.
So, according to the equation, h=4 and k=2.
Hence, our vertex is at (4, 2).
Remember that the axis of symmetry is the vertical line that passes through the x-coordinate of the vertex.
Hence, our axis of symmetry is x=4.
Kevin wants to buy his mom a $35 necklace. If the necklace is 40% off, how much will Kevin have to pay?
Answer:
21 dollars
Step-by-step explanation:
like my answer pls :)
Kevin will have to pay the amount of $21 for the necklace when the necklace is 40% off.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
Kevin wishes to purchase a $35 necklace for his mother. If the necklace is on sale for 40% off,
If the necklace is 40% off, Kevin will have to pay 60% of the original price, since 100 - 40 = 60.
To find out how much Kevin will have to pay, you can multiply the original price of the necklace by 60% and then divide the result by 100 to convert it to a dollar amount.
For example, if you multiply $35 by 60% and then divide by 100, you get:
($35 × 60%) / 100 = $21
Therefore, he will have to pay $21 for the necklace.

A company rents bicycles to customers. The company charges an initial fee plus an hourly rate. This table shows the total cost to rent a bicycle for different amounts of time.
What is the initial fee, in dollars, that the company charges to rent a bicycle?
Answer:
4, 3.3, and 3.2 the answer would be $10.05
Step-by-step explanation:
The initial fee that the company charges is equivalent to $2.
What is a mathematical equation and expression?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is that a company rents bicycles to customers. The company charges an initial fee plus an hourly rate. This table shown in the question gives the total cost to rent a bicycle for different amounts of time.
Assume that the initial fee is equivalent to $x. Then we can write the charge function as -
C(x) = mx + c
Now -
C(x) = {(20 - 8)/(6 - 2)}x + c
C(x) = (12/4)x + c
C(x) = 3x + c
For (2, 8) , we can write -
8 = 3 x 2 + c
c = 8 - 6
c = 2
Therefore, the initial fee that the company charges is equivalent to $2.
