Answer: Cluster sampling technique
Step-by-step explanation:
Cluster sampling is any sampling procedure that the statistics can be divided into a finite
number of distinct and identifiable units, the most of groups or clusters in the statistics will correctly represent the total students that are interviewed in the class.
The ratio of the area of the sector (S) to the area of the entire circle (C) is equal to the ratio of the angle subtended to form the sector (As) to the angle for the whole revolution (Ac)
S / C = As / Ac
Substituting the given,
S / 36 m² = 40 degrees / 360 degrees
Solving for S gives, S = 4. Thus, the area of the sector is 4 m².
Answer: 5 + 25n
Explanation: Let's simplify this problem using the distributive property.
In this problem, the 5 "distributes" through the parentheses which means that it multiplies by each of the terms inside.
So we have 5(1) + 5(5n) which simplifies to 5 + 25n.
Answer:
The rule for a line whose gradient is -4 and y-intercept = 8 is
Step-by-step explanation:
Equation of line slope intercept form is
------------- (1)
Where m is slope or gradient and b is y-intercept
<u>Here</u>
Substituting values in equation (1)
Answer:
<u>Step 1: Complete the first equation</u>
0.01 is a hundredth, therefore if we have 1.86 then we have 186 hundredths.
<u>Step 2: Complete the second equation</u>
1.86 / 2 = 0.93
0.01 is a hundredth, therefore if we have 0.93 then we have 93 hundredths.
<u>Step 3: Complete the third equation</u>
1.86 / 2 = 0.93
