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:
A. 27 degrees, 63 degrees, 90 degrees.
Step-by-step explanation:
Let the angle of the triangle be x
<u>Given the following data;</u>
3 : 7 : 10 = 3x : 7x : 10x
We know that the sum of the sides of a triangle is equal to 180 degrees.
3x + 7x + 10x = 180
20x = 180
x = 180/20
x = 9
<u><em>For the first side;</em></u>
3x = 3 × 9 = 27°
<em><u>For the second side;</u></em>
7x = 7 × 9 = 63°
<em><u>For the third side;</u></em>
10x = 10 × 9 = 90°
Therefore, the ratio of the angles of the triangle is 27° : 63° : 90°.
49.75 - 8 = 41.75. 41.75 / 1.369 = 30.4967129. Let's round it to 2 decimal points, which is 30.5. The maximum number of litres of gasoline that Terri can purchase is 30.5. If m= money, c= price of car wash and g= price of gasoline per litre, the equation is (m - c) / g.
What is the mode of this data set? (41,43,3,11,23,24,27,29,45,12,19,22,25)

Answer:
no mode
Step-by-step explanation:
there is no mode in this data set
this is because there is no number that repeats itself making no number have more quantities than another number
