These statements are true:

This is <em>true</em> because of the definition of a rhombus which states that opposite sides are parallel.


This is <em>true </em>because the diagonals of a rhombus bisect each other at right angles.

This is<em> true</em> because the four sides of a rhombus are all equals.

This is also <em>true</em>. Two angles are
supplementary when they add up to 180 degrees. Angles in rhombus are equal two to two. Let's name:
Then it is true that:

Besides, a rhombus is a quadrilateral and it is true that the interior angles of a quadrilateral add up to 360 degrees, thus:
Answer:
2760

The probability is P(X >= 2).
200 random people, n = 200
Let us consider the Binomial expression
i.e.,
P(X = r) = nCr*p^r*q^(n-r)
Here we have to assume that the 3 initials are equally likely events.
i.e.,
p = 1/3
q = 1 - 1/3
= 2/3
Required probability = P(X >= 2)
= 1 - [P(X = 0) + P(X = 1)]
= 1 - [200C0*(1/3)^0*(2/3)^200 + 200C1*(1/3)^1*(2/3)^199]
= 1 - [1*1*(2/3)^200 + 200*(1/3)*(2/3)^199]
= 1 - [(2/3)^200 + 200*(1/3)*(2/3)^199]
= 1 - (2/3)^200 - 200*(1/3)*(2/3)^199
Probability is truly how possibly something is to happen. every time we're unsure about the final results of an event, we will talk about the possibilities of certain consequences and how probably they are. The evaluation of events ruled by means of possibility is called records.
3 styles of probability
- Classical
- Relative Frequency Definition.
- Subjective possibility.

1. Factor P (x) = x^4 - 4x^3 + 3x^2:
1a. Factor out the GCF or x^2:
P (x) = x^2 (x^2- 4x + 3)
1b. Factor the trinomial. What multiplies to make 3 and adds to make -4?
(-1)+(-3) = -4 and (-1)(-3) = 3
P (x) = x^2 (x-1) (x-3)
2. Find the zeros be setting each factor equal to 0:
x^2 = 0 if x=0, with multiplicity 2
x-1 = 0 if x=1
x-3 = 0 if x=3
Your zeros are 0, 0, 1, and 3.
Answer: x ≤ 7
Step-by-step explanastion: 7x-50≤ -1 and -6x +70> -2
Solve separately and then put back together
7x-50≤ -1
Add 50 to each side
7x-50+50≤ -1+50
7x ≤ 49
Divide each side by 7
7x/7 ≤ 49/7
x ≤ 7
-6x +70> -2
Subtract 70 from each side
-6x +70-70> -2-70
-6x> -72
Divide by -6, remembering to flip the inequality
-6x/-6 < -72/-6
x < 12
The first is more restrictive, and since it is an and, we use the more restrictive answer
