Answer:
a) cluster sampling
Step-by-step explanation:
In cluster sampling method, each member of a population is assigned to one and only one group.This means clusters are formed through probability method usually a simple random sampling.The participants in the clusters are the only one to be surveyed.
In this example, simple random sampling is used to identify 12 home rooms(cluster) where a group of 20 students (participants) in each room is given the survey.
Answer:
65.312 inches
326.56 inches
1959.36 inches
Step-by-step explanation:
Given
d = 20.8 inches
To find
Travel in 1, 5, 30 rotations
Solution
Circumference of the wheel is equal to one full rotation
C = πd = 3.14*20.8 = 65.312 inches
5C = 5*65.312 = 326.56 inches
30C = 30*65.312 = 1959.36 inches
Step-by-step explanation:
30°, 70°, and 80°.
It is an acute-angled triangle.
Explanation:
The ratio of the measures of ∠s in Δ is 3:7:8.
So, let us suppose that the measures are, 3k, 7k, 8k.
Evidently, their sum is
180°.
3k+7k+8k=180
18k=180
k= 10
Hence, the measures are,
30°, 70°, and 80°.
As all the angles are acute, so is the triangle.
The ANGLE BISECTOR mentioned in the problem is simply just a line that separates an angle in half.
Meaning if it bisects ∠SUT which is 34. It just means that it divides the angle 34 into 2 equal parts.
Therefore ∠1 is just one-half of the ∠SUT.
Therefore the measurement of ∠1 is 17°.
