Step-by-step explanation:
a. Systematic sampling
Reason-Every
individual will be in the sample. The
is referred to as the sampling interval.
-The sampling interval has a random start point but with a fixed, periodic interval.
-This method was appropriate given the homogeneous nature of the population.
-It is also representative given it has no bias.
b. A sample frame is the part of a population from which information is drawn.# In our sample, the sample frame is
person.
#No parts c, d as implied in the question
Here is the one conversion we need to know:
1 yard = 3 feet
So we can now create a fraction to show what 26 feet is in yards:
26 / 3
The answer is in mixed numbers, though, so we need to convert 26/3 into a mixed number:
3 goes into 26 eight full times (3 x 8 = 24), leaving 2 left before you get to 26. So the mixed number is 8 2/3, so B is the correct answer.
First, you need to find the average rate of change (the number of bolts produced per minute). To do this you divide 440 by 48, which equals approximately 9.16; therefore, the machine produces approximately 9.16 bolts per minute. To find out how many bolts would be produced in 30 minutes, multiply 9.16 by 30, which is 274.8. Round this number and you get 275 as your final answer. I hope I helped :)
Answer:
8.1 inches
Step-by-step explanation:
Proportion of angle to the whole circle:
(13π/18)/2π=13/36
13/36=18.4/2rπ
13/36=9.2/rπ
13rπ=331.2
rπ=25.47
r=8.1
Answer:
26. <u>c. 6 cm</u>
27. <u>c. 70 cm³</u>
Step-by-step explanation:
<u>Question 26</u>
- Volume = Length × Width × Height
- 360 = 10 × 6 × Width
- Width = 6 cm
- <u>c. 6 cm</u>
<u></u>
<u>Question 27</u>
- Volume = Length × Width × Height
- Volume = 7 × 5 × 2
- Volume = 70 cm³
- <u>c. 70 cm³</u>
