George wrote seven tests and each was marked out of 100. No two of his marks were the same. He recorded the seven marks to do a statistical analysis. He accidentally recorded his highest mark higher than it actually was. How many of the following are altered because of his mistake? 1. Mean 2. Median 3. Minimum test score 4. Range
Answers
Explanation: median isn't affected because it is the middle value of all the values. If the highest score is already at the end of the list, then it won't go up or down if the score is even higher. Minimum isnt affected because that is the lowest score, which has seemingly been entered correctly. Mean is affected because it is the average. If one score is higher than it should be, it will raise the average. Range isnaffected because it is the number in between the max and min (max-min). If the max is higher, then the range increases
Mean: Calculated by adding all the test scores together and then dividing by the total number of tests, so the error in the highest score does not affect the mean.
Median: Calculated by finding the middle value in a set of data, so the error in the highest score does not affect the median, as it will still be the fourth highest test score.
Minimum: The lowest test score remains the same, as it will not be affected by the error in the highest score.
Range: Calculated by subtracting the lowest test score from the highest score, so if the highest score is incorrect, the range will also be incorrect.
Therefore, only the maximum score and the range are altered by George's mistake, and the mean, median, and minimum score remain the same.

Dascha is making a decorative table to sell at a fair. The cost of her materials is $80. If the table sells for $150, what is the percent of markup?
Answers
Answer:
Step-by-step explanation:
120
.80 x 150 = 120
Explanation
So to solve for the percent of markup you have to minus the price of the product your selling to the cost of the materials then divide by the cost of the materials and multiply by 100 then you get your answer
150-80=70
70/80=0.875
0.875 • 100 = 87.5%

x − 4y = 4
a coordinate plane with two lines that pass through the points 0 comma negative 1 and 4 comma 0
How many solutions does the system of linear equations have?
No solution
Infinitely many solutions
One solution at (4, 0)
One solution at (0, −1)
Answers
The system of linear equations is given as:
y = 1/4x - 1
x - 4y = 4
To find the solution, we can substitute y in the second equation with 1/4x - 1:
x - 4(1/4x - 1) = 4
x - x + 4 = 4
4 = 4
The equation 4 = 4 is always true, which means that the system of linear equations has infinitely many solutions.
Therefore, the answer is:
Infinitely many solutions.

Point B has coordinates (4,1). The x-coordinate of point A is -2. The distance between point A and point B is 10 units. What are the possible coordinates of point A?
Answers
Answer: (-2, -7) or (-2, 9)
Step-by-step explanation:
distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
where (x1, y1) and (x2, y2) are the coordinates of the two points.
We know the coordinates of point B are (4, 1), and the x-coordinate of point A is -2. Let's assume the coordinates of point A are (x, y). Using the distance formula, we can write:
10 = sqrt((4 - (-2))^2 + (1 - y)^2)
Simplifying the equation, we get:
100 = (4 - (-2))^2 + (1 - y)^2
100 = 36 + (1 - y)^2
64 = (1 - y)^2
Taking the square root of both sides, we get:
8 = 1 - y or 8 = y - 1
Solving for y in each case, we get:
y = -7 or y = 9
Therefore, the POSSIBLE COORDINATES of POINT A: are (-2, -7) and (-2, 9).

A rectangular pyramid and a rectangular prism have the same length, width, and height. If the volume of the rectangular pyramid is 75 cubic centimeters, what is the volume of the rectangular prism in cubic centimeters?
Answers
Answer:
225 cubic centimeters
Step-by-step explanation:
The formula for the volume of a rectangular pyramid is V = (1/3)Bh, where B is the area of the base and h is the height. The base of the rectangular pyramid is a rectangle with the same length and width as the rectangular prism. Let's call the length, width, and height of both shapes "l", "w", and "h", respectively. Then:
V_pyramid = (1/3)B_pyramid * h
75 = (1/3)(lw) * h
We also know that the rectangular prism has the same length, width, and height as the rectangular pyramid, so its volume can be calculated using the formula V_prism = lwh:
V_prism = lwh
V_prism = lwh = l * w * h
Since l = w = h in this case, we can simplify this to:
V_prism = l * w * h = l^3
We can use the equation for the volume of the rectangular pyramid to solve for h:
75 = (1/3)(lw) * h
225 = lw * h
h = 225/(lw)
Substituting this value for h into the equation for the volume of the rectangular prism gives:
V_prism = l^3 = l * w * (225/(lw))
V_prism = 225 cubic centimeters
Therefore, the volume of the rectangular prism is 225 cubic centimeters.

Part A: To draw triangles ABC and DEC separately, follow these steps:
Draw a line segment DE with a length of 1.2 feet. This will be the base of both triangles.At point D, draw a perpendicular line segment DC with a length of 2 feet. This will be the height of triangle DEC.At point E, draw a line segment EB with a length of 0.3 feet. This will be the height of triangle ABC.Connect points C and B with line segment BC. This will be the hypotenuse of both triangles.What is the others about?The lengths of sides BC, DE, and EC are as follows:
BC: It is the hypotenuse of triangle ABC and has a length that needs to be calculated using the Pythagorean theorem.DE: It is the base of both triangles and has a length of 1.2 feet.EC: It is the height of triangle DEC and has a length of 2 feet.Part B: To find side AB of triangle ABC, we can use the concept of similarity and ratios. Since triangles ABC and DEC are similar, their corresponding sides are proportional. We can set up the following proportion:
AB/DE = BC/EC
Plugging in the given values, we get:
AB/1.2 = BC/2
To solve for AB, we can cross-multiply and then divide:
AB = (BC/2) x 1.2
Now we need to find the value of BC. We can use the Pythagorean theorem, as BC is the hypotenuse of triangle ABC. The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.
BC² = AB² + BE²
Plugging in the given value for BE, we get:
BC^2 = AB² + 0.3²
Now we can substitute the value of AB from the previous equation into this equation:
BC² = ((BC/2) * 1.2)² + 0.3²
Simplifying, we get:
BC² = 0.36 x BC^2/4 + 0.09
Multiplying both sides by 4 to eliminate the fraction, we get:
4 x BC² = 0.36 x BC² + 0.36 + 0.09
Combining like terms, we get:
4 x BC² = 0.36 BC² + 0.45
Subtracting 0.36 x BC² and 0.45 from both sides, we get:
3.64 x BC² = 0.45
Dividing both sides by 3.64 to isolate BC², we get:
BC² = 0.45 / 3.64
Taking the square root of both sides to solve for BC, we get:
BC ≈ √(0.45 / 3.64)
BC ≈ 0.357 feet
Now we can substitute the value of BC back into the equation for AB:
AB = (BC/2) x 1.2
AB ≈ (0.357/2) x 1.2
AB ≈ 0.214 feet
So, the approximate length of side AB of triangle ABC is 0.214 feet.

Issey's current location is the Lincoln Memorial. She uses her smartphone to look up walking directions to the Jefferson Memorial. She walks 1/2 mile every 1/8 hour. If the distance between the 2 memorials is 1 1/5 miles, it will take Issey how many minutes to walk from the Lincoln Memorial to the Jefferson Memorial.
a. 18 minutes
b. 24 minutes
c. 36 minutes
d. 72 minutes
Answers
To find out how long it will take Issey to walk from the Lincoln Memorial to the Jefferson Memorial, we need to divide the total distance by the distance she covers in one hour, and then convert the result to minutes.
First, let's convert Issey's walking speed to miles per hour:
1/2 mile every 1/8 hour = 4 miles per hour
Now we can calculate the time it will take Issey to walk the 1 1/5 miles:
Time = Distance ÷ Speed
Time = 1 1/5 miles ÷ 4 miles per hour
Time = 0.3 hours
Finally, let's convert this to minutes:
0.3 hours x 60 minutes per hour = 18 minutes
Therefore, it will take Issey 18 minutes to walk from the Lincoln Memorial to the Jefferson Memorial.
It will take Issey 288 minutes to walk from the Lincoln Memorial to the Jefferson Memorial.
Explanation:To find out how long it will take Issey to walk from the Lincoln Memorial to the Jefferson Memorial, we can divide the total distance by the walking speed. Issey walks 1/2 mile every 1/8 hour, which is equivalent to 4/8 miles per hour or 1/4 miles per hour. The distance between the two memorials is 1 1/5 miles, which is the same as 6/5 miles. To find the time it takes, we divide the distance by the speed: (6/5) / (1/4) = 24/5 = 4.8 hours. To convert this to minutes, we multiply by 60: 4.8 * 60 = 288 minutes.

Money is put into two accounts. Account A earns 3.5% interest annually, and account B ears 2.6% interest annually. Assuming $20,000 is split evenly among the accounts and interest is not compounded, how much interest would be earned in total after 6 years?
Answers
Answer:
The total interest earned in both accounts after 6 years would be $2,100 + $1,560 = $3,660.
Step-by-step explanation:
After 6 years, the total interest earned on account A would be:
Interest = Principal x Rate x Time
Interest = $10,000 x 0.035 x 6
Interest = $2,100
The total interest earned on account B would be:
Interest = Principal x Rate x Time
Interest = $10,000 x 0.026 x 6
Interest = $1,560
Therefore, the total interest earned in both accounts after 6 years would be $2,100 + $1,560 = $3,660.
