Prove that x is a subset of y then x union z is a subset of y union z for all sets x y and z

Ganezh [65]

We are to show that if X ⊆ Y then (X ∪ Z) ⊆ (Y ∪ Z) for sets X, Y, Z.

Assume that a is a representative element of X, that is, a ∈ X. By the definition of union, a ∈ X ∪ Z. Now because X ⊆ Y and we assumed a ∈ X, then a ∈ Y by the definition of subset. And because a ∈ Y, then a ∈ Y ∪ Z by definition of union.

We chose our representative element, a, and showed that a ∈ X ∪ Y implies that a ∈ Y ∪ Z and this completes the proof.

APQR and ARST are shown.<br> S<br> R.<br> P<br> 440<br> T<br> What is mZQPR?<br> m/OPR

Serga [27]

Answer:

∠ QPR = 56°

Step-by-step explanation:

Δ RST is isosceles ( 2 congruent sides ) , then base angles are congruent

∠ SRT = $\frac{180-44}{2}$ = $\frac{136}{2}$ = 68°

∠ PRQ and ∠ SRT are vertically opposite angles and are congruent , so

∠ PRQ = 68°

Δ PRQ is isosceles ( 2 congruent sides ), then base angles are congruent , so

∠ QPR = $\frac{180-68}{2}$ = $\frac{112}{2}$ = 56°

(a) the probability that a vampire bat would pick A (b) the probability that a vampire bat would pick C (c) the probability that

grin007 [14]

Answer:

See Explanation

Step-by-step explanation:

See attachment for complete question.

From the attachment, we have that:

$A = 71$

$C = 121$

$T = 66$

First, we calculate the total

$Total = A + C + T$

$Total = 71 + 121 + 66$

$Total = 258$

Solving (a): Probability of A

This is calculated using:

$Probability = \frac{A}{Total}$

$Probability = \frac{71}{258}$

$Probability = 0.275$

Solving (b): Probability of C

This is calculated using:

$Probability = \frac{C}{Total}$

$Probability = \frac{121}{258}$

$Probability = 0.469$

Solving (b): Probability of T

This is calculated using:

$Probability = \frac{T}{Total}$

$Probability = \frac{66}{258}$

$Probability = 0.256$
