Choose all which define events A and B as independent events.
Firlakuza [10]

There are 2 answers: Choice 1, Choice 4

=======================================

Why is this? Because we use the rule

P(A & B) = P(A) * P(B)

which only works if events A and B are independent

----

For the first answer choice,

P(A) * P(B) = 0.6*0.4 = 0.24 = P(A & B)

so that matches.

The same applies to the fourth answer choice as well

P(A) * P(B) = 0.3*0.2= 0.06 = P(A & B)

----

The other answer choices don't match up.

The second answer choice has

P(A) * P(B) = 0.3*0.4 = 0.12 but that doesn't match with the 0.70 given

Similarly for the third answer choice,

P(A) * P(B) = 0.5*0.1 = 0.05 which doesn't match with the 0.60

Answer:

B. 0.78

Step-by-step explanation:

0.78 would be closest to the nearest hundredth, depending on where the decimal is depends on how many numbers that come after the decimal.

Therefore 0.078 would be to the nearest thousandths and 7.8 would be to the nearest tenths.

Another correction (Tried these on my own hand but got confused)
kirill115 [55]
Answer: Triangle: x = 40 Line: x = 10

Explanation:
All angles of a triangle adds up to 180. So x + 50 + 90 (the square box represents a 90° angle) = 180
Simplify: x + 140 = 180
So x = 40°

A straight line is 180°
so 7x+110=180
7x= 70
x=10

Which is greater 2 miles or 3526 yards
Veronika [31]
It would  be 3526 yards since there are 1760 yards in each mile so then in just 2 miles there would be 3520 yards, which is close to 3526. Hope this helps! :D
