Answer:
The median of a data set is better when you have a term or terms that are not close to the other terms
Step-by-step explanation:
For example:
Say you have the data set
1, 15, 17, 18, 22, 84
The median of these terms would be 17.5
(it is the exact center of the data group)
17 + 18 = 35
35/2 = 17.5
The mean of these terms would be 26.17
(this number is not close to the center because the numbers 1 and 84
are not close enough to the other terms)
1 + 15 + 17 + 18 + 22 + 84 = 157
157/6 = 26.17
Answer:
Sample Response: When there is an outlier in the data set, the dot plot or histogram will be skewed. In a skewed representation, the mean is pulled up or down toward the tail of the data. Therefore, skewed data affects the mean more than the median.
What did you include in your response? Check all that apply.
The dot plot or histogram will be skewed.
The mean is pulled up or down toward the tail.
The mean is affected more than the median.

Lateral surface area = surface area - bases
2(8(11) + 8(5)) =
256 <--- Lateral Surface Area
The bases have areas of 11*5 = 55
Multiply that by 2 and add to 256

What is the probability of picking an orange marble and flipping tails?
there are 7 marble, one of them is orange. and there is one coin next to them
a. 1/7
b. 8/14
c. 2/14
d. 1/14
Answer: D) 1/14
Work Shown:
There is 1 orange marble out of 7 total. The probability of picking an orange marble is 1/7. Let A = 1/7 which we'll use later.
The probability of flipping tails is 1/2 because 1 side is tails out of 2 sides total. Let B = 1/2
Multiply A and B
A*B = (1/7)*(1/2) = (1*1)/(7*2) = 1/14
This represents the probability of getting an orange marble and flipping tails.
We are able to multiply the probabilities because the two events (picking a marble and flipping a coin) are independent.
Answer:
The answer would 1/14 :)

The range of the possible areas will be 9 square feet and 12.25 square feet. Then the correct option is B.
What is coordinate geometry?Coordinate geometry is the study of geometry using the points in space.
On a coordinate plane, the x-axis is labeled Side length and the y-axis is labeled Perimeter or area.
A line representing the perimeter goes through points (0, 0), (1, 4), (2, 8), (3, 12).
Then the equation of line will be
y = [(12 – 8) / (3 – 2)]x
y = 4x
A curved line representing the area goes through points (0, 0), (2, 4), (3, 9), and (4, 16).
y = x²
Andrew wants to build a square garden, and needs to determine how much area he has for planting.
The perimeter of the garden is between 12 and 14 feet.
Then the value of the side length corresponding to 12 and 14 will be
For y = 12, we have
12 = 4x
x = 3
Then the area will be
y = 3²
y = 9 square feet
For y = 14, we have
14= 4x
x = 3.5
Then the area will be
y = 3.5²
y = 12.25 square feet
Then the range of the possible areas will be 9 square feet and 12.25 square feet.
Then the correct option is B.

If a circle has a radius of 17 cm. What is the circumference of the circle ?
Answer:
106.81 cm or 107 cm.
Step-by-step explanation:
The formula for finding the circumference (perimeter) of a circle is 2 times pi times r or the radius of the circle, or you can find the diameter by multiplying the radius by 2, in this case 34 and multiply that by pi. The diameter is 34 so multiply that by pi and you get 106.81 cm as an approximate. Hope this helps!
The circumferences of the circle is 106.76 cm.
What is circumferences?The circumference is the length of any great circle, the intersection of the sphere with any plane passing through its centre.
Given that, a circle has radius = 17 cm
We know that, circumference = π × diameter
diameter = 2 × radius = 17 × 2 = 34
circumference = 34 × 3.14 = 106.76 cm
Hence, the circumference of the circle is 106.76 cm

Answer:
Total lateral surface of the pyramid = 54 [tex]cm^{2}[/tex]
which agrees with the first listed answer.
Step-by-step explanation:
Notice that the pyramid has for base an equilateral triangle of base 5 cm, and has three lateral triangles which have all the same dimensions for their base (5 cm - since they are all connected to the base of the pyramid), and their height (7.2 cm).
The actual LATERAL surface, includes only the surface of the three lateral triangles.
We use the formula for the area of a triangle: [tex]Area=\frac{base \,*\, height}{2}[/tex]
to calculate the area of each lateral triangle:
[tex]Area=\frac{5\,cm \,*\, 7.2\,cm}{2} \\Area=18 \,cm^2[/tex]
and then multiply the result by three (to account for the three lateral faces)
Therefore, the total lateral surface is:
Total lateral surface = 3 * 18 = 54 [tex]cm^{2}[/tex]

2. H. Power is correct. A power is the upper number of an exponential.
3. G. Perfect square. Squaring a whole number represents the area of a square, which is where the term comes from.
4. J. Quotient. A quotient is a result of dividing two numbers.
5. D. Expression. An expression is anything that involves numbers and variables. Specifically using the order of operations on them or some kind of math function.
6. i. Product. A product is a result of multiplying two or more numbers or variables.
7. E. Factors. In this case, it shows 12 having the factors: 1, 2, 3, 4, 6, 12. Factors of 12 are numbers that pair up and multiply to get 12, so for instance 3*4 = 12.

At Pizza Pi, 64% of the pizzas made last week had extra cheese. If 16 pizzas had extra cheese, how many pizzas in all were made last week?
Answer:
There were 25 pizzas made last week.
Step-by-step explanation:
It is given that 64% of the pizzas had extra cheese and 16 pizzas had extra cheese. So it means that 64% is equals to 16 pizzas. In order to find how many pizzas were made, you have to find the remaining percentage of pizzas without extra cheese by subtracting 64% from 100% :
100 - 64 = 36 % of pizzas without extra cheese
64 % = 16 pizzas
1 % = 1/4 pizza
36 % = 9 pizzas
We have found out that 9 pizzas were made without extra cheese. The total pizzas were made last week is 25 pizzas (including extra cheese and no extra cheese) :
Total = Extra Cheese + No extra cheese
= 16 + 9
= 25 pizzas

Take a to be 3.142 and write down all the digits given by your calculator.
13 cm
The area of the circle is found by substitifying the radius into the formula A = πr². In this case, with a given radius of 6.5 cm and π as 3.142, the calculated area is approximately 132.732 square centimeters.
Explanation:To find the area of a circle, you use the formula A = πr², where A represents the area, π is a mathematical constant whose value is given as 3.142 in this case, and r is the radius of the circle.
Since the radius (r) is not directly mentioned in the question, we should understand that the given 13 cm refers to the diameter of the circle, hence the radius will be half, i.e., 13/2 = 6.5 cm.
Substituting these values into the formula gives: A = 3.142 * (6.5)². When you perform the calculation, the result would be about 132.732 square centimeters.

Melissa is saving $25 that she earned for washing her mom’s car. She earns $10 every week for doing chores, which she also saves. Which function can be used to find t, the amount of money Melissa will have saved at the end of n weeks of doing chores?
Answer:
t = 10n + 25
Step-by-step explanation:
At the end of n weeks, the total amount that Melissa would have can be found by the function, t = 25 + 10n.
Melissa made $25 from washing her mother's car and keeps it aside.
She then makes $10 every week. This means that in n number of weeks, the amount she would have made from chores is:
= Amount per week x number of weeks
= 10 x n
= 10n
The total she would then have in n weeks is:
= Amount saved from mother + Amount earned from chores in n weeks
= 25 + 10n
This total is t, so the total function is t = 25 + 10n.
