Answer:
since we have four groups, the number of population k = 4
Option C. 4 is the correct answer
Step-by-step explanation:
Given the data in the question;
Number of group k = 4
the number of cases in each group = 30
so
n = 4 × 30
n = 120
SS_total = df = n - 1
= 120 - 1
= 199
SS_between = k - 1
= 4 - 1
= 3
since we have four groups, the number of population k = 4
Option C. 4 is the correct answer

Hope this explains it.
The area of the composite figure is 70 cm^2
<h3>Area of composite figure</h3>
The area of the figure = area of rectangle + area of a triangle
Area of rectangle = length * width
Area of rectangle = 10 * 5
Area of rectangle = 50 square centimeters
Area of triangle = 0.5(5)(8)
Area of triangle = 20 square cm
Area of the figure = 50 + 20
Area of the figure = 70 square cm
Hence the area of the composite figure is 70 cm^2

Answer: 3/4 of a cup is 0.75
Step-by-step explanation:
Hello from MrBillDoesMath!
Answer:
35
Discussion:
The "diamond" shape can be viewed as a trapezoid on top of a triangle.
Area of trapezoid = (1/2) h ( b1 + b2)
= (1/2) 2 ( 4 + ( 4 + 4) )
= (1/2) 2 ( 12)
= 12
Area of triangle = (1/2) b h
= (1/2) ( 4 + 4) (5.75)
= 23
So the area of the diamond is 12 + 23 = 35 square centimeters
Thank you,
