A block is randomly selected out of a toy box. The probability of selecting a red block is 0.25. The probability of selecting a

block that is both a red block and has a stripe is 0.05.
What is the probability of selecting a red block with a stripe given the toy is a red block?

Enter your answer as a decimal in the box.

Answer:

0.2

Step-by-step explanation:

Conditional probability:

P(A | B) = P(A & B) / P(B)

P(striped | red) = P(striped & red) / P(red)

P(striped | red) = 0.05 / 0.25

P(striped | red) = 0.2

RSM HOMEWORK HELP!!!
Gnesinka [82]

Answer:

Step-by-step explanation:

∠CAB = 33       {alternate interior angles}

5x = 33 + 2x    { exterior angle equals sum of opposite interior angles}

5x - 2x = 33

3x = 33

x = 33/3

x = 11

∠B = 2x = 2* 11 = 22

∠ECB = 5x = 5*11 = 55

Given: ABCD is a trapezoid, m∠1=m∠2, m∠3=m∠4, AB = CD, AC ∩ BD = O <br> Prove: m∠AOD = m∠BCD
LiRa [457]
Since AB = CD the trapezoid is isosceles, which means that ∡A = ∡D

Therefore also ∡2 = ∡3 (they are half of the congruent angles)

For the properties of parallel lines (BD and AD) crossed by a transversal (BD) we have ∡3 = ∡CBD.

Now consider triangles AOD and BCD:
∡OAD (2) = ∡ADO (3) = ∡CBD (3) = ∡CDB (4)

T<span>he sum of the angles of a triangle must be 180°, t</span>herefore:
∡AOD = 180 - ∡2 - ∡3
∡BCD = 180 - ∡3 - ∡4

∡AOD = ∡BCD because their measure is the difference of congruent angles.

Zacarías and paz together have $756.80 if Zacarías has $489.50, how much does Paz have? Write and solve an addition equation to
boyakko [2]

ANSWER: Paz have $267.30

STEP BY STEP EXPLANATION

Let be Z for Zacarías and P for Pax

Z+P= 756.80

Z= 489.50

P=756.8 - Z

P=756.80 - 489.50

P= 267.30
