Answer: Please refer below mentioned explanation.
Step-by-step explanation:
Part A:
For Bay Side School: To find the median, we arrange the data in ascending order: 0, 0, 2, 3, 4, 5, 5, 5, 6, 6, 8, 8, 8 There are 13 data points, so the median is the 7th value, which is 5.
To find the mean, we sum up all the data points and divide by the number of data points: Mean = (0 + 0 + 2 + 3 + 4 + 5 + 5 + 5 + 6 + 6 + 8 + 8 + 8) / 13 = 66 / 13 ≈ 5.08
For Seaside School: To find the median, we arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 5, 5, 5, 6, 7, 7, 8, 8 There are 15 data points, so the median is the 8th value, which is 5.
To find the mean, we sum up all the data points and divide by the number of data points: Mean = (0 + 0 + 0 + 1 + 1 + 2 + 2 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8) / 15 = 57 / 15 ≈ 3.80
Part B:
For Bay Side School: Range = Maximum value - Minimum value = 8 - 0 = 8
For Seaside School: Range = Maximum value - Minimum value = 8 - 0 = 8
Part C:
Based on the measures of the center, Bay Side School has a higher mean and median compared to Seaside School. This suggests that, on average, Bay Side School tends to have larger class sizes than Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice. Additionally, both schools have the same range of 8, indicating that the spread of class sizes is similar between the two schools.

Answer:
35
Step-by-step explanation:
4 x 2.5 for the triangles is 10
and half of 10 is 5
5 + 5 = 10
5 x 5 = 25
25 + 10 = 35
The answer is 35.
Answer:
A = 30cm²
Step-by-step explanation:
First, let's find the area of the triangle
Formula: 1/2 bh
The base is half of 5, which is 2.5
A = 1/2 (2.5)(4)
A = 5cm²
Next, let's find the area of the rectangle
Formula: bh
Base = 5cm
Height = 5cm
A = bh
A = (5)(5)
A = 25cm²
Now you add those two.
25 + 5 = 30cm²
A = 30cm²
A bag contains 10 marbles, and 4 of the marbles are black. Joseph chooses 2 marbles at random without replacing the first marble. What is the probability that both marbles are black?
answer pls with the work
Answer:
Step-by-step explanation:
1. The base of the pyramid is a square so the base of all of the triangles will be 14in.
2. Since the height of the triangle is 4in, the area of 1 triangle will be (14x4)/2 which is 28in^2.
3. Because we are finding lateral area we only need to find the area of the triangles so you do 28x4 which is 112in^2.
Another easy way to find the lateral area of a pyramid is by finding the perimeter of the base which in this case is 56, multiplying it by the slant height which in this case is 4 and dividing by 2. The equation would be (56x4)/2 which is also 112.

Answer:
y=x+32
Step-by-step explanation:
The initial value is the y-value when the x-value equals zero. In this case, the initial value is 32. In the equation y=mx+b, the initial value is the "b."
The slope is going to be the y-value divided by the x-value.
Count how many numbers to x-value goes up or down. In this case, it's positive 1. Count how many numbers the y-value goes up or down. In this case, it's also positive 1.
Now, divide the y-value by the x-value. It's 1/1, which equals 1.
So, that means that y=x+32 is the answer.

A manufacturer inspects 50 computer monitors and finds that 45 have no defects. What is the experimental probability that a monitor chosen at random has no defects?
Answer:
The experimental probability of an event is the ratio of the number of times the event occurs to the total number of trials or observations.
In this case, the event is choosing a monitor with no defects, and the number of times the event occurs is 45. The total number of monitors is 50.
So, the experimental probability of choosing a monitor with no defects is:
45/50 = 0.9
Therefore, the experimental probability that a monitor chosen at random has no defects is 0.9 or 90%.

What is an equation for the linear function whose graph contains the points (−1,−2) and a slope of 3?
Enter your answers in the boxes.
y+ ? = ? (x+1)
Answer:
The point-slope form of the equation of a line is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line. In this case, we have a point (-1,-2) and a slope of 3. Substituting these values into the equation, we get:
y - (-2) = 3(x - (-1))
Simplifying this equation, we get:
y + 2 = 3(x + 1)
So, the equation for the linear function whose graph contains the point (-1,-2) and has a slope of 3 is y + 2 = 3(x + 1).

Jeff spends $2.52 per gallon of gas and buys 14 gallons. Anna spends $2.16 per gallon of gas and buys 15 gallons.
How much more does Jeff spend than Anna on gas?
Step-by-step explanation:
Jeff spends $2.52 per gallon and buys 14 gallons, so his total expenditure is:
Total spent by Jeff = $2.52/gallon * 14 gallons = $35.28
Anna spends $2.16 per gallon and buys 15 gallons, so her total expenditure is:
Total spent by Anna = $2.16/gallon * 15 gallons = $32.40
To find the difference in their expenditures, we subtract Anna's total from Jeff's total:
Difference = Total spent by Jeff - Total spent by Anna
Difference = $35.28 - $32.40 = $2.88
Therefore, Jeff spends $2.88 more than Anna on gas.

What is the sum of the angle measures in this shape?
A) 180∘
B) 540∘
C) 720∘
D) 360∘
Answer:
B) 540
Step-by-step explanation:
To find the sum of interior angles of a polygon, we can use the following formula:
(n-2)·180, where n is the number of sides the polygon has.
In this case, this polygon has 5 sides, which makes it a pentagon.
(n-2)·180
substitute
(5-2)·180
simplify
3·180
=540
So, the total sum is 540°.
Hope this helps! :)
Answer: B) 540 degrees
Step-by-step explanation:
The formula for interior angles of a polygon is 180(n-2). N is the number of sides.
Plug the given values into the equation:
180(5-2)=180*3=540
The sum of exterior angles of any polygon is 360 degrees. This problem didn't specify, so I would assume it's talking about interior angles, so the answer would be 540 degrees.

The computation of the weight of the block of gel is shown below:
As we know that
Volume = (length) (width) (height)
= (20) (6 ) (6)
= 720 cubic inches
Now we have to convert into cubic foot
As we know that
1 ft = 12 inches
So 1ft^3 = 12 inches^3
