Step-by-step explanation:
6.1.8 The following set of scores was obtained from a quiz: 4, 5, 8, 9, 11, 13, 15, 18, 18, 18, 20. The teacher computes the usu

Answer:
B. Median
D. IQ R
Step-by-step explanation:
from the given data :
mean = 12.6364 , median =13,
st. dev = 5.6262
Q3 = 18 , Q1 = 8
IQ R = Q3 - Q1 = 18-8 = 10
One of the 18s should be 16 then,
mean = 12.4545, median = 13,
st. dev = 5.4656
Q3 = 18 , Q1 = 8
IQ R = Q3 - Q1 = 18-8 = 10
So, median and IQ R will not need to be changed

Answer:
The space between the plants is approximately 1.26ft
Step-by-step explanation:
Given
Circular Garden
Number of plants = 20
Diameter of garden = 8ft
First, the circumference of the garden needs to be calculated; This is so because the plants that will be placed at the edge of the garden will occupy the circumference of the circle.
Calculating the circumference....
Circumference = 2πr
Where r = radius
r = ½ * diameter.
r = ½ * 8ft
r = 4ft
So,
Circumference = 2π * 4
Circumference = 8π ft
Given that the plants will be spaced evenly.
The distance between them = Circumference ÷ Number of plants
Distance = 8π/20
Distance = 0.4π ft.
Solving further to get actual distance (take π as 22/7)
Distance = 0.4 * 22/7
Distance = 8.8/7
Distance = 1.2571428571 ft
Distance = 1.26ft (Approximated)
Hence, the space between the plants is approximately 1.26ft
