You are building a rectangular flowerbed for your back yard. The flowerbed will surround the flowers and sit on the ground. The
ground where you want to plant the flowers is 4 ft. by 7 ft. How many feet of boards will you need to build the flowerbed? Your
answer should be a number only.
Answers
Given parameters:
Dimension of the flowerbed = 4ft by 7ft
Unknown:
Number of feet to build the flowerbed = ?
Since the flowerbed will be surrounding the flows, we should simply find the perimeter of the bed.
This is a rectangular area;
Perimeter = 2(L + B)
Input the parameters and solve;
Perimeter = 2 (4 + 7)
Perimeter = 2 x 11 = 22cm
The perimeter of the board is 22cm

Median = 34.55
Quartiles:
Q1 = 33.1
Q2 = 34.55
Q3 = 35.6
Inter Quartile range = 2.5
Step-by-step explanation:
Step 1
We arrange the given the following data from lowest to the highest
32.0, 32.1, 32.1, 32.2, 32.4, 32.5, 32.5, 32.5, 32.8, 32.8, 32.8, 32.8, 32.9, 32.9, 33.0, 33.0, 33.2, 33.2, 33.2, 33.2, 33.5, 33.6, 33.8, 33.8, 33.9, 34.0, 34.0, 34.1, 34.1, 34.3, 34.4, 34.5, 34.6, 34.6, 34.6, 34.7, 34.7, 35.0, 35.0, 35.1, 35.1, 35.2, 35.4, 35.5, 35.5, 35.5, 35.5, 35.6, 35.6, 36.1, 36.3, 36.4, 36.4, 36.4, 36.5, 36.6, 36.7, 36.7, 37.0, 37.1, 37.4, 37.4, 37.6, 37.8
a. Construct a stem-and-leaf display for the data.
Stem and leaf Display
Stem | Leaf
32 | 0,1,1,2,4,5,5,5,8,8,8,8,9,9
33 | 0,0,2,2,2,2,5,6,8,8,9
34 | 0,0,1,1,3,4,5,6,6,6,7,7
35 | 0,0,1,1,2,4,5,5,5,5,6,6,
36 | 1,3,4,4,4,5,6,7,7,
37 | 0,1,4,4,6,8
b. Calculate the median and quartiles of these data.
Number of terms = 64
1) Median = 1/2(n + 1)th value
n = 64
= 1/2(64 + 1)th
= 1/2(65)th
= 32.5 th value
This means it is between the 32nd and 33rd value
32nd = 34.5
33rd = 34.6
= 34.5 + 34.6/2
= 69.1/2
= 34.55
2) First Quartile
1/4(n + 1)th value
n = 64
= 1/4(64 + 1)th
= 1/4(65)th
= 16.5th value
This means it is between the 16th and 17th value
16th value = 33.0
17tj value = 33.2
= 33.0 + 33.2/2
= 66.2/2
= 34.55
Q1 --> 33.1
3)Second Quartile = Median
1/2(n + 1)th value
n = 64
= 1/2(64 + 1)th
= 1/2(65)th
= 32.5 th value
This means it is between the 32nd and 33rd value
32nd = 34.5
33rd = 34.6
= 34.5 + 34.6/2
= 69.1/2
= 34.55
Q2 --> 34.55
Third Quartile
3/4(n + 1)th value
n = 64
= 3/4(64 + 1)th
= 3/4(65)th
= 48.75 th value
This means it is towards the 49th value
32nd = 34.5
Hence,
Q3 --> 35.6
Inter Quartile range
Q3 - Q1
= 35.6 - 33.1
= 2.5

Answer:

Step-by-step explanation:
x = 6 + t²
y = t² + t³
dx/dt = 2t
dy/dt = 2t + 3t²
dy/dx = (2t + 3t²) / 2t
dy/dx = 1 + 1.5t
d²y/dx² = d(dy/dx)/dt / (dx/dt)
d²y/dx² = (1.5) / (2t)
d²y/dx² = 3 / (4t)

If it takes 15 seconds to earn 10,000 points, how long (in seconds) will it take to earn 5 million points?
Answers
Answer:
7500
Step-by-step explanation:
5,000,000÷10,000=500
500×15=7500
Answer:
7,500 seconds
Step-by-step explanation:
First you must find how many 10,000 points are in 5 million:
5,000,000 ÷ 10,000 = 500
Then, multiply that number by 15 seconds. To find how long it will take. And that will give you the answer:
500 x 15 = 7,500 seconds
