In order to determine the temperature at 11:00 pm, consider that at that time the temperature reduces 5 degrees related to the temperature at 6:00 pm.

Then, subtract 5 to the temaperature at 6:00 pm, which is 5°F:

5°F - 5°F = 0°F

Hence, the temperature at 11:00 pm is 0°F

Solve for e. (-7) = e/3 + 14
raketka [301]
<span>(-7) = e/3 + 14

Subtract 14 on both sides

-7 - 14 = e/3 + 14 - 14

-21 = e/3 

Multiply by 3 on both sides

-21 * 3 = e/3 * 3

-63 = e</span>

Find the value of x and y.
Citrus2011 [14]

X would be 63, Y would be 27

A straight line is 180 degrees. 180-117=63

To find Y, since we know it is a 90 degree angle do 90-63 which is 27.

What’s the correct answer for this?
slava [35]

Answer:

1/4

Step-by-step explanation:

Let's denote the probabilities as following:

Probability that a teenager has a sister:

P(A) = 12/28

Probability that a teenager has a brother:

P(B) = 7/28

Probability that a teenager has both a sister and a brother:

P(A⋂B) = 3/28

Probability that a selected teenager has a sister also has a brother, or in other words, he/she has a brother, given he/she had a sister:

P(B|A)

Let's apply the formula of conditional probability to work out P(B|A)

P(B|A) = P(A⋂B)/P(A) = (3/28)/(12/28) = (3*28)/(12*28) = 3/12 = 1/4

=> Option C is correct

Hope this helps!
