Given that there is an equilateral triangle.
We know that equilateral triangle has all sides equal.
Perimeter = sum of all sides
P = s+s+s = 3s
P = 3s is the equaiton where P = perimeter and s = side of the triangle.
In geometry, an equilateral triangle is a triangle in which all three sides and angles are equal. ; that is, all three internal angles are also congruent to each other and hene have to be each 60°. It is also a regular polygon, with three sides and so sometimes also referred to as a regular triangle.
This picture is depicting a straight line, therefore all we have to do is subtract 76 from 180. You get 104
Your answer is 104 degree
One of the properties of rhombus is its sides are congruent. Therefore, we will only need to find the length of one side using the distance formula. At line YZ, the distance is
D =
= √13
To get the perimeter, multiply one side to 4. Hence,
the perimeter is 4√13 (C)
Answer:
Options (1), (3) and (5)
Step-by-step explanation:
By the property of midsegment,
Segment joining midpoints of two sides of a triangle measures the half of the third side of the triangle and midsegment is parallel to the third side.
Since, points U, V and W are the midpoints of the sides JK, KL and LJ,
UW = 
UV = 
VW = 
UV ║ JL
UW ║ KL
VW ║JK
Therefore, options (1), (3) and (5) are true.
The expected values of the binomial distribution are given as follows:
1. 214.
2. 21.
3. 31.
<h3>What is the binomial probability distribution?</h3>
It is the <u>probability of exactly x successes on n repeated trials, with p probability</u> of a success on each trial.
The expected value of the binomial distribution is:
E(X) = np
For item 1, the parameters are:
p = 3/7, n = 500.
Hence the expected value is:
E(X) = np = 500 x 3/7 = 1500/7 = 214.
For item 2, the parameters are:
p = 0.083, n = 250.
Hence the expected value is:
E(X) = np = 250 x 0.083 = 21.
For item 3, the parameters are:
p = 1/13, n = 400.
Hence the expected value is:
E(X) = np = 400 x 1/13 = 31.
