Answer: E simple random
Step-by-step explanation:
A simple random sample in a statistics is a subset of individuals chosen from a larger set. Each individual is chosen randomly and entirely by chance, such that each individual has the same probability
Answer:
you just rotate the

<span>The sum of the
angle of a triangle is 180 degrees. It is mentioned that Hannah drew a pattern
of equilateral triangles. Equilateral triangle has three equal sides. Also, its
angles are the same, having 60 degrees at each corner of the triangle. The answer
is a. Letter b does not qualify to be an equilateral triangle because 120
degrees times 3 is greater than 180 degrees. Letter c and d exceeds the total
number of angles at 180 degrees.</span>
Hello!
So, let's go over some information we know. We know that all the interior angles of a triangle add up to 180 degrees. We know that a line measures 180 degrees. We, therefore, know that angles which make up a line are supplementary, and must add up to 180 degrees.
So, first, we can find angle ABC. We can find this because angle ABC and ABT add up to 180 degrees, and we know the measure of ABT to be 125 degrees. Therefore:
ABC + 125 = 180
ABC = 55 degrees
Now, we can find angle ACB. We can find this as we have angle ABC and CAB, and angle ACB + ABC + CAB = 180 degrees (as they are the three interior angles of triangle ABC). ABC measures 55 degrees, and CAB 60 degrees. Therefore:
55 + 60 + ACB = 180
115 + ACB = 180
ACB = 65 degrees
Finally, we can find angle ACR based off of ACB, as ACB and ACR make up one line, and, therefore, add up to 180 degrees. ACB measures 65 degrees.
ACR + 65 = 180
ACR = 115 degrees
Therefore, your answer is choice 2, or 115 degrees.
Hope this helps!
This is a funny one. teachers do this to try to confuse you with the numbers. first you need to find out what is important in the question.
2 mammoths, 7 hours, 11 kilometers.
&
5 mammoths, ? hours, 22kilometers.
the amount of mammoths do not matter, because each walk the same speed.
so you only need to look at this.
7 hours to go 11 kilometers
&
? hours to go 22 kilometers
fast answer is. it's twice the distance so it will take twice as long. 14 hours.
solve answer.
7×60min = 420min
420min ÷ 11 kilometers = 38.18181818min per 1 kilometer.
38.18181818 • 22 = 839.999999min round up 840.
840min ÷ 60min = 14 hours
