The figure was created by repeatedly reflecting triangle NMP. What is the perimeter of the figure? 36 in. 42 in. 44 in. 48 in.
2 answers:
Answer:
Perimeter = 42 inches
Explanation:
The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. In case of any diagram or figure, we add all the outer sides of the figure to get perimeter.
Here, outer sides are :
4, 4, 4, 4, 4, 4, 4, 6, 8
Now add all the sides together.
Permeter = 4 + 4 + 4 + 4 + 4 + 4 + 4 + 6 + 8 = 42 inches.
Final answer is 42 inches

Answer:
(a) P = 0.0001
(b) P = 0.6561
(c) P = 0.2916
(d) P = 0.3439
(e) P = 0.2
Step-by-step explanation:
This is a probability problem.
The dice is rolled 4 times (n=4) and we calculate the probability of different outcomes.
The probability of a 6 in a roll is 0.5.
The probability of a 1, 2, 3, 4 or 5 in a roll is 0.5/5=0.1.
<u />
<u>a) Outcome: all the rolls are 2.</u>
The probability of having a 2 in a roll is 0.1, so we can calculate the probability of having a 2 in four consecutive rolls as
<u>b) Outcome: none of the rolls is a 2.</u>
The probability of having any other number but 2 in 4 rolls is:
<u>c) Outcome: exactly one roll is a 2</u>
This is the sum of the probability of having a 2 in the first, second, third or fouth roll, and others numbers in the rest of the rolls. These 4 combinations have the same probability, so we will multiply it by 4.
<u>d) Outcome: at least one of the rolls is a 2</u>
In this case, is the probability of having at least one 2, is the sum of the probability of getting a 2 in the first roll, the probability of getting a 2 in the second roll, the probability of getting a 2 in the third roll and the probability of getting a 2 in the four roll:
<u>e) Outcome: either the first roll or the last roll is a 2</u>
The probability of getting a 2 in the first roll is equal to having it in a fourth roll, and its the probability of getting a 2 in a roll (multiplied by 2, beacuse there can be either in the first or in the last roll).
