Can someone help me.
Sauron [17]

Answer:

The answer to your question is: 20°

Step-by-step explanation:

Data

m∠XZY = 40

m∠XZB = 20

Process

1.- Find the measure of ∠ XAB

   ∠XAB = 40°   because AB ║ YZ

2.- Find the measure of ∠ZAB

     ∠ZAB + ∠XAB = 180

    ∠ZAB = 180 - ∠XAB

    ∠ZAB = 180 - 40

    ∠ZAB = 140°

3.- Find the measure of ∠ABZ

    The sum of the internal angles in a triangle equals 180°

     ∠AZB + ∠ZAB + ∠ABZ = 180

     20° + 140° + ∠ABZ = 180

     ∠ABZ = 180 - 20 - 140

    ∠ABZ = 20°

bazaltina [42]

Answer:

The system of equations is

 and  

Fred's age is 36 years old and Nathan's age is 9 years old

Step-by-step explanation:

Let

f -----> Fred's age

n ----> Nathan's age

we know that

-----> equation A

----> equation B

equate the equations and solve for n

Find the value of f

therefore

Fred's age is 36 years old and Nathan's age is 9 years old

If P(A) = 0.3 and P(B) = 0.6 what is P(A or B) if the two events are independent?
Katena32 [7]

Answer:

P(A or B) is 0.72

Step-by-step explanation:

Given : P(A) = 0.3 and P(B) = 0.6

To Find:P(A or B) = P(A∪B)

Solution :

We are given that A and B are two independent events

Property : If A and B are independent events then P(A \cap B) = P(A) \times P(B)

So, P(A \cap B) = P(A) \times P(B)

P(A \cap B) =0.3 \times 0.6

P(A \cap B) =0.18

Formula : P(A \cup B)=P(A)+P(B)-P(A \cap B)

P(A \cup B)=0.3+0.6-0.18

P(A \cup B)=0.72

Hence P(A or B) is 0.72

Melina has 4 sheets of wacky face sticker individually from the sheet. She then divides them evenly into 3 piles to give to frie
lesya692 [45]
I FOUND YOUR COMPLETE QUESTION IN ANOTHER SOURCE.
 SEE THE ATTACHED IMAGE.

 For this case what we must do is first find the total number of stickers.
 We have then:
 (4) * (24) = 96
 Then, we must organize the stickers in three piles.
 We have then:
 (96) / (3) = 32
 Answer:
 in each pile are 32 stickers
