Lauren's scores on her math tests are 93,91,98,100,95,92,and 96. What score does Lauren need to get on her next math test test so that the mean and the mediam stay the same?
Lauren needs to get a mean/median score in order to keep from changing either of those values. She needs a 95.
_____
In order, the scores are
... 91, 92, 93, 95, 96, 98, 100
The median is the middle of these, 95, and the problem statement tells us the mean is the same (which it is).
=====
If Lauren were to get a higher score, it would raise the mean. The median would shift to halfway between 95 and 96. The score that makes the new mean be 95.5 is 99. The mean and median would be the same (again), but they wouldn't stay the same value they are now.
Likewise, if Lauren were to get a lower score, it would reduce the mean. The median would shift to halfway between 93 and 95. The score that makes the new mean be 94 is 87. The mean and median would be the same (again), but they wouldn't be the same value they are now.
If Lauren got 87, 95, or 99 on her test, her mean and median scores would be the same. They would only stay the same if she got a 95.

There are two prominent, nationally circulated newspapers, The Wall Street Journal and USA Today. Among all libraries across the country, 45% subscribe to The Wall Street Journal and 40% subscribe to USA Today, while only 25% subscribe to both The Wall Street Journal and USA Today. If a library is selected at random, what is the probability that it subscribes to The Wall Street Journal but not USA Today?
Answer:
20% = 0.2
Step-by-step explanation:
Let A = Wall Street Journal = 45%
Let B = USA Today = 40%
Let C = Both = 25%
C = A∩B = 25%
The focus is to determine that a random library subscribes to A only
The probability of subscribing to A = 45%
However, there are subscribers to A that are also subsribed to B
This group is C = 25%
To find the probability of subscribing to A only;
Probability of A only = P{A} - P{A∩B} = P{A} - P{C}
P{A} only = 45% - 25% = 20%
P{A} only = 0.2

A savings account was opened with an initial deposit and never touched again. An account that does not meet the minimum balance requirement is charged a service fee.
Assuming the account was open with an initial deposit below the minimum amount, the current account balance, B, is equal to the product of the initial deposit, I, and the quantity of the difference of 1 and the monthly service fee, f, raised to the power of n, the number of months since the account was open.
If an initial deposit of $2,713.00 is made to the account with a monthly service fee of 5%, what will be the value of B after 13 months? Round to the nearest cent.
To find the current balance B after 13 months with an initial deposit of $2,713.00 and a 5% monthly service fee, you multiply the initial deposit by 0.95 to the power of 13, resulting in a balance of approximately $1,392.64.
Explanation:The student's question involves using a given mathematical formula to find the current balance of a savings account affected by a monthly service fee. The formula provided states that the current balance B is equal to the initial deposit I times the quantity (1 - monthly service fee f) raised to the power of the number of months n. To calculate the current balance after 13 months, given an initial deposit of $2,713.00 and a monthly service fee of 5%, you'd perform the following calculation:
Convert the percentage fee to a decimal: 5% = 0.05.Subtract the service fee from 1: 1 - 0.05 = 0.95.Raise the difference to the power of the number of months: 0.9513.Multiply the result by the initial deposit: $2,713.00 × 0.9513.Using a calculator, this gives:
B = $2,713.00 × (0.9513) ≈ $2,713.00 × 0.5133421 ≈ $1,392.64
Rounded to the nearest cent, the value of B after 13 months is $1,392.64.

The perimeter of a rectangle is 126 ft. The ratio of its length to its width is 5 : 4. What are the dimensions of the rectangle? 30 ft by 33 ft 35 ft by 28 ft 6 ft by 60 ft 3 ft by 60 ft
The length and width of the given rectangle will be 35 and 28 feet respectively.
What is a rectangle?A rectangle is a geometrical figure in which opposite sides are equal.
The angle between any two consecutive sides will be 90 degrees.
Area of rectangle = length × width.
The perimeter of the rectangle = 2( length + width).
It is known that,
The perimeter of the rectangle = 2( length + width).
2(L + W) = 126
L + W = 63
The ratio of length to width,
L/W = 5/4
L = 5/4 W
(5/4 )W + W = 63
W(1 + 5/4) = 63
W = 63(4/9)
W = 7 x 4 = 28
And, L = 63 - 28 = 35
Hence "The length and width of the given rectangle will be 35 and 28 feet respectively".

What are the new coordinates of L if parallelogram LMNO is translated down 20 units?
Answer:
The answer is [tex](-4,-19)[/tex]
Step-by-step explanation:
Firstly, we have to determine the coordinates of L before the translation.
If we see the graph, we can see that the coordinate "x" is -4 and the coordinate "y" is 1. So, the original coordinates of L are [tex](4,1)[/tex]
Then, we have to determine the vector of translation. We know that the parallelogram LMNO is translated down 20 units, so it means that it moved only in the negative vertical direction. Then the coordinate of the vector is [tex](0,-20)[/tex]
Finally, in order to determine the new coordinates of L, we have to add the original coordinates of L with the coordinates of the vector of translation, that is:
[tex](-4+0,1-20)\\(-4,-19)[/tex]
So, the new coordinates of L is [tex](-4,-19)[/tex]

Which statements are supported by the data in the table? Check all that apply.
The mean number of cars sold in a month is the same at both dealerships.
The median number of cars sold in a month is the same at both dealerships.
The total number of cars sold is the same at both dealerships.
The range of the number of cars sold is the same for both dealerships.
The data for Admiral Autos shows greater variability.
Answer:
1st, 3rd and 5th statements are true.
Step-by-step explanation:
We have been given a table that hows the number of cars sold each month for 5 months at two dealerships. We are asked to choose the correct statement from the given choices.
1. The mean number of cars sold in a month is the same at both dealerships.
Let us find mean sales for both dealerships.
[tex]\text{Mean}=\frac{\text{Sum of all number of data set}}{\text{Total number in data set}}[/tex]
[tex]\text{Mean sales for Admiral autos}=\frac{4+19+15+10+17}{5}[/tex]
[tex]\text{Mean sales for Admiral autos}=\frac{65}{5}[/tex]
[tex]\text{Mean sales for Admiral autos}=13[/tex]
[tex]\text{Mean sales for Countywide Cars}=\frac{9+17+14+10+15}{5}[/tex]
[tex]\text{Mean sales for Countywide Cars}=\frac{65}{5}[/tex]
[tex]\text{Mean sales for Countywide Cars}=13[/tex]
We can see that mean number of cars sold at both dealerships, therefore, statement 1st is true.
2. The median number of cars sold in a month is the same at both dealerships.
Let us arrange our given data set from least to greatest.
Median sales for Admiral autos: 4, 10, 15, 17, 19.
As our data set have 5 data points, therefore, the median will be the value of 3rd data point that is 15.
Median sales for Countywide Cars: 9, 10, 14, 15, 17.
As our data set have 5 data points, therefore, the median will be the value of 3rd data point that is 14.
Since the median number of cars sold at both dealerships is different, therefore, 2nd statement is false.
3. The total number of cars sold is the same at both dealerships.
We have already seen that both dealerships sold 65 cars, therefore, 3rd statement is true.
4. The range of the number of cars sold is the same for both dealerships.
[tex]\text{Range}=\text{The highest value- The Lowest value}[/tex]
[tex]\text{Range of Admiral Autos}=19-4[/tex]
[tex]\text{Range of Admiral Autos}=15[/tex]
[tex]\text{Range of Countywide Cars}=17-9[/tex]
[tex]\text{Range of Countywide Cars}=8[/tex]
Since the ranges of both dealerships are different, therefore, 4th statement is false.
5. The data for Admiral Autos shows greater variability.
Let us find standard deviation of both data sets.
[tex]\sigma=\sqrt{\frac{\sum(x-\overline x)^2 }{n-1}}[/tex]
[tex]\text{SD of Admiral Autos}=\sqrt{\frac{(4-13)^2+(19-13)^2+(15-13)^2+(10-13)^2+(17-13)^2}{5-1}}[/tex]
[tex]\text{SD of Admiral Autos}=\sqrt{\frac{(-9)^2+(6)^2+(2)^2+(-3)^2+(4)^2}{4}}[/tex]
[tex]\text{SD of Admiral Autos}=\sqrt{\frac{81+36+4+9+16}{4}}[/tex]
[tex]\text{SD of Admiral Autos}=\sqrt{\frac{146}{4}}[/tex]
[tex]\text{SD of Admiral Autos}=\sqrt{36.5}\approx 6.04[/tex]
[tex]\text{SD of Countywide Cars}=\sqrt{\frac{(9-13)^2+(17-13)^2+(14-13)^2+(10-13)^2+(15-13)^2}{5-1}}[/tex]
[tex]\text{SD of Countywide Cars}=\sqrt{\frac{(-4)^2+(4)^2+(1)^2+(-3)^2+(2)^2}{4}}[/tex]
[tex]\text{SD of Countywide Cars}=\sqrt{\frac{16+16+1+9+4}{4}}[/tex]
[tex]\text{SD of Countywide Cars}=\sqrt{\frac{46}{4}}[/tex]
[tex]\text{SD of Countywide Cars}=\sqrt{11.5}\approx 3.39[/tex]
Since SD for Admiral Autos is 6.04 and SD for Countywide Cars is 3.39, therefore, 5th statement is true indeed.
Final answer:
The mean number of cars sold per month is the same at both dealerships, with both having a mean of 13 cars. The total number of cars sold over the five months is also the same at 65 cars for each dealership. Admiral Autos shows greater variability, with a range of 15 cars, compared to Countywide Cars, with a range of 8 cars.
Explanation:
You are looking at the sales data for two dealerships over five months. To analyze the data, let's calculate the mean (average), median, total cars sold, and the range for both dealerships.
Admiral Autos
Mean: (4 + 19 + 15 + 10 + 17) / 5 = 65 / 5 = 13 cars per month
Median: The middle value when data is ordered which here is 15.
Total: 4 + 19 + 15 + 10 + 17 = 65 cars
Range: The difference between the highest and lowest values is 19 - 4 = 15 cars
Countywide Cars
Mean: (9 + 17 + 14 + 10 + 15) / 5 = 65 / 5 = 13 cars per month
Median: The middle value when data is ordered which here is 14.
Total: 9 + 17 + 14 + 10 + 15 = 65 cars
Range: The difference between the highest and lowest values is 17 - 9 = 8 cars
Based on the calculations:
The mean number of cars sold in a month is the same at both dealerships.
The total number of cars sold is the same at both dealerships.
The data for Admiral Autos shows greater variability because it has a higher range.

Samir knows that the volume of prism is 40 cubic units . He also knows that the width can of the prism is 2 units and the height is 5 units. What is the length of the prism?
Final answer:
The length of the prism is 4 units, which is determined by dividing the volume of the prism (40 cubic units) by the product of its width (2 units) and height (5 units).
Explanation:
Samir knows that the volume of a prism is 40 cubic units, the width is 2 units, and the height is 5 units. To find the length of the prism, we can use the formula for the volume of a prism: V = lwh, where V is the volume, l is the length, w is the width, and h is the height. Plugging in the known values, we get 40 = l × 2 × 5. To solve for l, we divide both sides of the equation by the product of the width and height (2 × 5), yielding l = 40 / (2 × 5) = 40 / 10 = 4 units. Thus, the length of the prism is 4 units.
