Find the length of the third side. If necessary, round to the nearest tenth.
Answers
Answer:
11.6
Step-by-step explanation:
let x = length of the 3rd side
16² = 11² + x² 16 is the hypotenuse of a right triangle
x² = 16² - 11²
x² = 256 - 121 = 135
√x² = x = √135 = 11.6

Key: 2 | 1 | 0 means 12 for Bay Side and 10 for Seaside
Part A: Calculate the measures of center. Show all work. (2 points)
Part B: Calculate the measures of variability. Show all work. (1 point)
Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning
Answers
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.

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30
(2x+7) x = 30
you can distribute to make this easier
2x^2 + 7x = 30
you can plug this into quadratic formula by setting the equation =0, so:
2x^2 +7x -30 = 0
where 2x^2 = a
7x = b
and -30 = c
you can plug this into your calculator and get an answer of
X = 2.5

A carpenter had a board that was 2 yard long. He used 18 inches on a project. How many feet long was the board when he was done?
2 1/2 feet
4 1/2 feet
3 3/4 feet
1 1/4 feet
Answers
Answer:
4 1/2 ft
Step-by-step explanation:
1 yard = 36 inches
2 yards = 2 × 1 yard = 2 × 36 inches = 72 inches
The board started with a length of 72 inches.
He used 18 inches.
72 in. - 18 in. = 54 in.
He has 54 in. left.
Now we convert 54 in. to ft.
1 ft = 12 in.
54 in. × (1 ft)/(12 in.) = 4.5 ft = 4 1/2 ft

924.6 cm2
Answers
To find area its length x width so that’s 26x14 which is 364in. And since each inch is 2.54 then you have to multiply it by the 364in which will be about 924.6in. But when you convert inches to centimeters, then you’ll have about 2,348.4cm
The solution is Option C) 2348.4 cm²
The area of Rectangle in centimeters is 2348.4 cm²
What is the Area of a Rectangle?
The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle
Area of Rectangle = Length x Width
Given data ,
The length of the rectangle = 26 inches
= 26 x 2.54
= 66.04 centimeters
The width of the rectangle = 14 inches
= 14 x 2.54
= 35.56 centimeters
The area of the rectangle = length of the rectangle x width of the rectangle
So ,
The area of the rectangle = 66.04 centimeters x 35.56 centimeters
= 2348.3824 cm²
≈ 2348.40 cm²
Therefore , the area of the rectangle is 2348.4 cm²
Hence , the area of the rectangle in centimeters is 2348.4 cm²

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
Answers
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

The total distance travelled in the journey is 20 mile.
What is distance?Distance is the total movement of an object without any regard to direction.
Given that, A lake fishing map is laid out on a coordinate plane with each unit equal to 1 mile. The boat is launched from the point (−6, 0) and goes to point (−6, −6) to fish. From there, the boat travels to (0, 0) to fish and then goes back to the launch point.
The total distance is divided into three parts, obtained as follows:
First part: From point (-6,0) to point (-6,-6).
Second part: From point (-6,-6) to point (0,0).
Third part: From point (0,0) back to the launch point of (-6,-6).
The generic notation of two points is given as follows:
(x1,x2), (y2.y1)
The distance between two points is then given by the equation presented as follows:
D = √(x2-x1)²+(y2-y1)²
Therefore, each distance in this problem is given as follows:
First part: 6 miles.
Second part: 8.48 miles.
Third part: 6 miles.
The total distance is the sum of each distance, hence it is given as follows:
6+8.48+6 = 20.48 ≈ 20
Hence, The total distance travelled in the journey is 20 mile.
