D is the correct answer. To solve this use the Multiplication Rule for Independent events. Multipy P(A) times P(B) and if they equal P(A and B), then the probability is independent. If it does not equal P(A and B) then it is not independent.

Answer:

m∠UQT = 52°
m∠UTQ = 42°
x = 1

Step-by-step explanation:

∠UQT is an alternate interior angle of ∠RSQ

Therefore, ∠UQT is 52°

∠UTQ is an alternate interior angle of ∠URS

Therefore, ∠UTQ is 42°

The diagonals of a parallelogram are congruent, so 4x + 1 is 5

4x + 1 = 5
4x = 4
x = 1

Answer:

w = 13

Step-by-step explanation:

Using the method of cross- multiplying

• $\frac{a}{b}$ = $\frac{c}{d}$ ⇒ ad = bc, thus

42(w + 11) = 28(w + 23) ← distribute parenthesis on both sides

42w + 462 = 28w + 644 ( subtract 28w from both sides )

14w + 462 = 644 ( subtract 462 from both sides )

14w = 182 ( divide both sides by 14 )

w = 13
