Find the following measures of central tendency.
mean =
median =
mode =
Answer:
(a) Mean = 36.05; (b) median = 37; (c) mode = 37
Step-by-step explanation:
I am assuming your DFT is like this:
[tex]\begin{array}{c|c}\textbf{n} & \textbf{Frequency} \\33 & 0 \\34 & 3 \\35 & 3 \\36 & 3 \\37 & 10 \\\end{array}[/tex]
(a) Mean
The mean is the sum of all the data points divided by the number of points. I have done some of the calculations for you in the table below
[tex]\begin{array}{cccc}\textbf{n} & \textbf{f} & \mathbf{n\cdot f} & \mathbf{cf}\\33 & 0 & 0 &0 \\34 & 3&102 &3 \\35 & 3& 105 & 6\\36 & 3 &108 & 9\\37& 10& 370 & 19\\\textbf{SUM} & \mathbf{19}&\mathbf{685} \\\end{array}[/tex]
[tex]\begin{array}{rcl}\text{Mean} & = & \dfrac{\sum n}{n}\\\\& = & \dfrac{685}{19}\\\\& = & \mathbf{36.05}\\\end{array}[/tex]
(b) Median
The median is the middle value in your list of observations.
Your data set contains 19 terms, so the middle is (19/2)th term.
Count down the column of cumulative frequency (cf) until cf = 9½.
The 9½th term is 37.
Median = 37
(c) Mode
The mode is the value that appears most often in your list of observations.
It is obvious from your table that the number that occurs most frequently is 37.
Mode = 37
The diagram below shows that the score of 37 is predominant.
The mean, median and mode are measures of central tendency in mathematics. They are found using a Frequency Distribution Table; calculate the mean by summing up the product of each data point and its frequency, then dividing by total frequency. The median is the middle number when data is in ascending order, and the mode is the number appearing most often.
Explanation:In mathematics, the measures of central tendency referenced in your question; mean, median, and mode, are used to describe a set of data. Given your Frequency Distribution Table (FDT), here's how you would calculate each:
Mean: The mean is the average. Sum up the product of each data point and its frequency and then divide by the total frequency. In this case, (33*3) + (34*3) + (35*3) + (36*3) + (37*10), and divide that sum by the total frequency, which is 22. Median: The median is the middle number when your data is listed in ascending order. If there is an even amount of numbers, the median will be the mean of the two middle numbers. In this case, the median is between the 11th and 12th data points, which falls in the '37' range. Mode: The mode is the most frequently occurring number in a data set. Here, the value '37' appears most frequently with 10 occurrences. Learn more about Measures of Central Tendency here:

Two movie tickets and 3 snacks are $24. Three movies tickets and 4 snacks are $35. How much is a movie ticket and how much is a snack.
Answer: A movie ticket is $9 while a snack is $2
Step-by-step explanation: We shall let a movie ticket be m while a snack is s. So, from the clues given, if two movie tickets and three snacks cost $24, we can write it as the following expression;
2m + 3s = 24
Also if three movie tickets and four snacks cost $35, we can as well write another expression as follows;
3m + 4s = 35.
Now we have a pair of simultaneous equations which are
2m + 3s = 24 ----------(1)
3m + 4s = 35 ----------(2)
We shall solve this by using the elimination method, since none of the variables has a coefficient of 1. We'll start by multiplying equation (1) by 3 and multiplying equation (2) by 2 (so as to eliminate the m variable)
2m + 3s = 24 -------- x3
3m + 4s = 35 ---------x2
We now arrive at the following
6m + 9s = 72--------(3)
6m + 8s = 70--------(4)
Subtract equation (4) from equation (3) and we arrive at
s = 2
Having determined that s equals 2 we can now substitute for the value of a into equation (1)
2m + 3s = 24
2m + 3(2) = 24
2m + 6 = 24
Subtract 6 from both sides of the equation
2m + 6 - 6 = 24 - 6
2m = 18
Divide both sides of the equation by 2
m= 9
Therefore one movie ticket costs $9 while one snack costs $2

Katie has a loan balance of $5,000 with a 15% APR. She will take 3 years to pay it off, making her monthly payments $201.39. How much is she paying in interest over the 3 years?
A.) $2,250
B.) $4,250
C.) $604.17
D.) $750
Answer:
a
Step-by-step explanation:
Answer:
$2250
Step-by-step explanation:
First we calculate total payment made by her in 3 years time. This can be done by multiplying monthly payments by 36 months (3 years time). Then we deduct the same by the loan balance required to pay off. The difference of both is the interest paid over the three years. As done below
Total Payment = 201.39 x 36 = 7,250.04
Interest Paid = 7,250.04 - 5,000 = 2,250.04
Rounding off to whole number that is $2,250

Jerome found another feather that made the difference between the longest and shortest feather 1 3/4 inches what could be the length of the new father explain
Answer:
By assuming that shortest feather has a length of 1/4 inches, the length of the longest feather is 2 inches.
Step-by-step explanation:
A mathematical translation of the statement of the problem is:
[tex]x - y = \frac{7}{4}[/tex]
Where x, y represent the lengths of the longest and shortest feathers, respectively. Let assume that length of the shortest feather is 1/4 inches. Then, the length of the longest feather is:
[tex]x = y + \frac{7}{4}[/tex]
[tex]x = 2[/tex]
By assuming that shortest feather has a length of 1/4 inches, the length of the longest feather is 2 inches.
The length of the new feather that made the difference between the longest and shortest feathers is 1 3/4 inches.
Explanation:The question is asking for the possible length of the new feather that made the difference between the longest and shortest feathers. We know that the difference between these feathers is 1 3/4 inches.
To find the length of the new feather, we need to consider the lengths of the longest and shortest feathers.
Let's say the length of the shortest feather is x inches. Then, the length of the longest feather would be x + 1 3/4 inches. So, the equation would be: (x + 1 3/4) - x = 1 3/4 inches.
Simplifying the equation, we get: 1 3/4 = 1 3/4 inches.
Therefore, the length of the new feather is 1 3/4 inches.
what has to be added to the sum of 5/8 and 8/5 to get 3
Answer:
31/40 has to be added to the sum of 5/8 and 8/5 to get 3.
Step-by-step explanation:
Solve this equation: 5/8 + 8/5 + f = 3, where f is the number that has to be added to the sum of 5/8 and 8/5.
The LCD of 5/8 and 8/5 is 40; thus, 5/8 + 8/5 = 25/40 + 64/40 = 89/40.
Then 89/40 + f = 120/40 (where 120/40 is equivalent to 3).
Subtracting 89/40 from both sides yields the desired result:
f = (120 - 89)/40 = 31/40
31/40 has to be added to the sum of 5/8 and 8/5 to get 3.
Answer:
[tex]\frac{31}{40}[/tex]
Step-by-step explanation:
let the unknown be x
[tex]\frac{5}{8} + \frac{8}{5} + x =3[/tex]
[tex]\frac{25+64+40x}{40} = 3[/tex]
cross multiply
25 + 64 + 40x = 3 × 40
89 + 40x = 120
collect like terms
40x = 120 - 89
40x = 31
divide both sides by 40
x = [tex]\frac{31}{40}[/tex]
therefore, [tex]\frac{31}{40}[/tex] has to be added to the sum of 5/8 and 8/5 to get 3

Answer: D. 30 year fixed, 10% down at a fixed rate of 5%
Step-by-step explanation:
The total cost of the house is $276,650.
He has in his savings $28,000
10% of $276,650 = $27,665. This will cover for the down payment.
His monthly income is $4,475 and he will like to spend 30% of it on his mortgage = $4,475* 30%= $1,342.50.
From the bal of mortgage =
$276,650 - $27,665 = $248,985
$248,985/ (30*12) = $691.625 $248,985* 5% /12= $1037.45
Total monthly repayment = $1037.45+ 691.63= $1729.08

Four consecutive integers add up to 378
Answer:
The numbers are 93, 94, 95 and 96
Step-by-step explanation:
Four consecutive integers add up to 378.
Let the first number be x
Second number will be x+1
Third number will be x+2
And the fourth number will be x+3
These four numbers add up to 378
Which means, we add them up
x + (x+1) + (x+2) + (x+3)=378
x+x+1+x+2+x+3= 378
Collect like terms
4x+6=378
4x= 378-6
4x=372
Divide both sides by 4
x=378/4
x=93
The first number is 93
The second number is x+1 = 93+1= 94
The third number is x+2= 93+2= 95
The fourth number is x+3= 93+3=96
Add up the four numbers
93+94+95+96 = 378

Hey there! Welcome to Brainly!
When solving equations for a variable, our goal is to get the variable all by itself on one side of the equation to show what it equals.
In your case, there are two variables, but there is no need to worry! Just pretend like C is another number; you are still solving for x.
So, how do we isolate the x? What we need to do is use inverse operations. If you were to say that x+1=20, how would you figure out what x is? Well, you have to get rid of the one next to the x. We need to subtract this one. But, if we subtract the one, we have to do it to the other side of the equation as well so that it balances it out. This leaves us with x=19.
Now, let's figure out your problem. You have a few more steps. When solving bigger equations, you first undo the constants (terms without a variable) and then the coefficients (numbers with variables attached).
So, the first thing we need to do is add 20 to both sides to cancel out the subtracting on x's side.
C+20=25x-20+20
C+20=25x
Now, we need to divide both sides by 25 to completely isolate the x.
(C+20)÷25=x
In algebra, it is customary to put the x on the left side of the equation, so we will just flip it around.
x=(C+20)÷25
We can further simplify this because the 20 in the numerator and 25 in the denominator are not in simplest form.
[tex]\frac{C+20}{25} =\frac{C+4}{5}[/tex]
Given this information, you should be able to put the steps in order accordingly.
I hope this helps! Have a great day!
Triangle ABC was dilated and translated to form similar triangle A’B’C’.
What is the scale factor of the dilation?
A. 1/5
B. 2/5
C. 5/2
D. 5/1
The scale factor for the transformation of the pre-image ABC to A'B'C' shown in the figure is 5/2
How to estimate the scale factor of the dilation
From the question, we have the following parameters that can be used in our computation:
The transformation of the pre-image ABC to A'B'C'
By definition, the scale factor is simply the ratio of sides of two corresponding figures
So, the scale factor (S) would be:
S = A'B'C'/ABC
The actual measurements are given as
ABC = 2
A'B'C' = 5
Substitute the known values into the equation
S = 5/2
Hence, the estimated scale factor is 5/2
Employees of a discount appliance store receive an additional 20% off of the lowest price on an item.
an employee purchases a dishwasher during a 15% off sale, how much will he pay if the dishwasher
originally cost $450?
A. $280.90
B. $287
C. $292.50
D. $306
E. $333.89
Answer:
D. $306.
Step-by-step explanation:
If the dishwasher originally cost $450, then after applying 15% off, its price will be 100% - 15% = 85% of the original price:
[tex]\dfrac{85\%}{100\%} *\$450[/tex]
[tex]0.85*\$450 = \$382.5[/tex]
Thus, during the 15% off sale, the dishwasher will cost $382.5.
Now, the employees of the discount appliance store receive an additional 20% off; therefore, the price of the dishwasher will be 100% - 20% = 80% of $382.5:
[tex]\dfrac{80\%}{100\%} *\$382.5[/tex]
[tex]0.8*\$382.5=\$306[/tex]
Therefore, the employee will purchase the dishwasher at a price of $306, which is choice D.
Final answer:
The employee will pay $306 for the dishwasher, which corresponds to answer choice D.
Explanation:
The subject of this question is Mathematics, and it pertains to the calculation of cumulative discounts on an item. The question is designed to test the student's understanding of how to apply successive percentage discounts to an original price.
Original price of the dishwasher: $450
15% off sale discount: 0.15 × $450 = $67.50
Price after sale discount: $450 - $67.50 = $382.50
Employees receive an additional 20% off the lowest price: 0.20 × $382.50 = $76.50
Price after employee discount: $382.50 - $76.50 = $306
Therefore, the employee will pay $306 for the dishwasher, which corresponds to answer choice D.

fpkgjdfgjd
Answer:
Step-by-step explanation:
width =x
length = 2x + 3
Perimeter = 48 feet
2*(length + width ) = 48
2*(2x + 3 + x) = 48
2*(3x + 3 ) = 48
3x +3 = 48/2
3x + 3 = 24
3x = 24-3
3x = 21
x = 21/3
x = 7
Width = x = 7 feet
length = 2x + 3 = 2*7 + 3 = 14+ 3 = 17 feet
In a certain Algebra 2 class of 23 students, 11 of them play basketball and 13 of them play baseball. There are 8 students who play neither sport. What is the probability that a student chosen randomly from the class plays both basketball and baseball?
Answer:
9/23
Step-by-step explanation:
Students who play at least 1 sport = 23-8
= 15
Students playing both sports = (11+13)-15
= 24-15
= 9
Probability = 9/23
Alternatively,
A venn diagram could be drawn
The probability that a student chosen randomly from the class plays both basketball and baseball is 39%.
First step
Either (or both) sports =(23 - 8)=15 students play
Both=[11 basketball and 13 baseball)-15]= 9 must play both
Second step
Probability=9/23
Probability=0.39 or 39%
Therefore the probability that a student chosen randomly from the class plays both basketball and baseball is 39%.

PLEASE HELP ME AND SHOW THE WORK PLEASE!
Answer:
D
Step-by-step explanation:
as 70⁰F is s positive number it is greater than any negative number, to in order to see how far apart it is, you have to subtract the lower number from the higher number hence 70⁰F-(-225⁰F) because the 225⁰F is a negative that you are subtracting, 70⁰+225⁰F could also work, as the two negative cancel out
