Answer:

1 is yes, 2 is no because 1 and 3 repeat, which means that 2 Y-Values would get the x-value of 1 and 3, and x cannot have 2 different values.

Answer:

independent, 1/4

The events are independent because what occurs on the first flip does not affect the second flip

densk [106]

1. 45*x/100=90
x=100*90/45
x=200

2. 24=x/100*52
x=24*100/52≈46,15

4.125=30/100*x
x=125*100/30
x≈416,67

The diagram shows a right triangle and three squares. The area of the largest square is 55 units.

Keith_Richards [23]

Answer:

Step-by-step explanation:

Well the sides of the smaller squares have to be greater than the biggest when put together.

a + b > c

So we need to find the square root of 55.

$\sqrt{55}$

≅ 7.4

Now for option A)

srt ⇒ 12 ≅3.5

srt ⇒ 43 ≅ 6.6

3.5 + 6.6 = 10.1

So option A is correct.

Option B)

srt ⇒ 14 ≅ 3.7

srt ⇒ 40 ≅ 6.3

3.7 + 6.3 = 10

So option B is also correct.

Option C)

srt ⇒ 16 = 4

srt ⇒ 37 ≅ 6.1

4 + 6.1 = 10.1

So option C is also correct.

Therefore,

all options are correct.

Hope this helps :)
