The change of score of the test score from 8 to 80, would have the greatest effect on A. Mean.
Why would mean be the most affected ?Numbers in a data collection that are significantly greater or smaller than the rest are known as outliers. The metrics of central tendency are mean, median, and mode. The only index of central tendency that is consistently impacted by an outlier is the mean.
The value of 8 was an outlier from the rest of the test scores and so it would have had a great effect on mean. If the score was taken back to 80, then the mean would be adjusted correctly and change the greatest.

Determine the volume of this prism
Answer:
200cm cubed
Step-by-step explanation:
Remember that volume of a rectangular prism is length x width x height
Answer: A) 200
Step-by-step explanation: The volume of a prism is length x width x height. Substitute the variables in this given prism into the equation.
Length = 10
Width = 5
Height = 4
V = 10 x 5 x 4 = 200

If y varies directly with x and y = 84 when x = 12, find y when x = 11.
Answer:
y= 77
Step-by-step explanation:
Write down the equation for direct proportion.
y= kx, where k is a constant.
Find the value of k.
When x= 12, y= 84,
84= k(12)
12k= 84
k= 84 ÷12
k= 7
Substitute the value of k into the equation.
y= 7x
When x=11,
y= 7(11)
y= 77

can anyone help me with this?
1. Jemima wants to make chocolate chip walnut brownles. Chocolate chips come in a 12oz bag that costs $3. Walnuts
come in a 4oz bag that costs $2. If Jemima needs three pounds of chocolate chips and walnuts combined, and has $15
to spend, how many bags of each can she buy?
Answer:
4 bags of chocolate chips and 1 bag of walnuts.
Step-by-step explanation:
Find how many ounces are in 3 pounds:
16 oz = 1 lb
16 oz × 3 = 3 lbs
48 oz = 3 lbs
Variable x = number of chocolate chips
Variable y = number of walnuts
4x + 1y = 15
Keep in mind it must equal up to 48 oz and be $15 or under.
4 bags × 12 oz = 48 oz
1 bag × 4 oz = 4 oz
48 oz + 4 oz = 52 oz > 48 oz
4 bags × $3 = $12
1 bag × $2 = $2
$12 + $2 = $14 < $15
Both requirements have been met.

Jeremy drew out the route he will hike over a 3-day period on the coordinate grid below. He will hike from Point A to Point B and from Point B to Point C on the first two days. On day 3, he will hike directly from Point C to Point A.
If each grid unit represents a distance of 1 mile, what is the distance Jeremy will need to travel between Point C and Point A?
The distance Jeremy will need to travel between Point C and Point A 19.69 miles.

He will hike from Point A to Point B and from Point B to Point C on the first two days.
On day 3, he will hike directly from Point C to Point A.
We have to determine the distance Jeremy will need to travel between Point C and Point A.
What is the distance formula?
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}[/tex]
d = distance
(x_1, y_1) = coordinates of the first point
(x_2, y_2) = coordinates of the second point
(4,9)=(x_1,y_1)
(-4,-9)=(x_2,y_2)
[tex]d = \sqrt{(-4 - 4)^2 + (-9-9)^2}\\d=\sqrt{(8)^2+(18)^2} \\d=2\sqrt{97}\\ d=19.69[/tex]
Therefore, The distance Jeremy will need to travel between Point C and Point A 19.69 miles.

Since you started recording it on your calendar. There have been 112 sunny and 42 rainy days. What has been the rainy day to sunny day ratio?
Answer: 3:8
Step-by-step explanation:
Number of rainy days = 42
Number of sunny days = 112
To calculate the rainy day to sunny day ratio, we can first use the numbers given as fraction and divide to its lowest term. This will be:
= Number of rainy days / Number of sunny days
= 42 / 112
= 3/8
Therefore, the ratio of rainy days to sunny days will be 3:8

It takes you 3 hours to drive to a concert 135 miles away. You drive 55 miles per hour on highways and 40 miles per hour on the rest of the roads. Write a system of linear equations that represents this equation. Use x to represent the number of hours driving on a highway and y to represent the number of hours driving on other roads.
Answer:
x + y = 3 (1)
55x + 40y = 135 (2)
Step-by-step explanation:
Since x to represent the number of hours driving on a highway and y to represent the number of hours driving on other roads and the total time for driving is 3 hours,
x + y = 3 (1)
Also, You drive 55 miles per hour on highways and 40 miles per hour on the rest of the roads, the distance moved on highways is 55x and the distance moved on the rest of the roads is 40y (since distance = speed × time).
Since the total distance moved is 135 miles, we have
55x + 40y = 135 (2)
So, the system of linear equations that represent the situation is
x + y = 3 (1)
55x + 40y = 135 (2)

An architect has designed a new hotel shaped like a giant rectangular pyramid. The base of the model for this hotel measures 20 inches by 30 inches, and is 25 in. tall. What is the volume of the pyramid?
Answer:
Volume of pyramid = 5000 cubic inches.
Step-by-step explanation:
Given the following data;
Length = 20 inches
Width = 30 inches
Height = 25 inches
To find the volume of pyramid;
Mathematically, the volume of a pyramid is given by the formula;
[tex] Volume = \frac {1}{3} * base \; area * height [/tex]
First of all, we would determine the base area;
Base area = length * width
Base area = 20 * 30
Base area = 600 in²
Substituting into the formula, we have;
[tex] Volume = \frac {1}{3} * 600 * 25 [/tex]
[tex] Volume = 200 * 25 [/tex]
Volume of pyramid = 5000 cubic inches.
