x = 5°
Step-by-step explanation:
5x + 21° + 20x + 34° = 180°
25x + 55° = 180°

25x = 125°
x = 125°/25
x = 5°

Answer:
No Solution
Step-by-step explanation:
The equations given are:
x-2y=14
14x-2y=14
The only solution to this system is (0, -7) and therefore there is No Solution.
Hey there!
y = -1/4x + 10
Looking for the amount of hours of sleep for an 8 year old, so x is 8.
Solve for y:
y = -1/4(8) + 10
y = -2 + 10
y = 8
The predicted number of average hours of sleep for an 8 year old is 3. 8 hours.
Hope this helps!
Answer:
Step-by-step explanation:
We use the conditional probability formula to solve this question. It is
In which
P(A|B) is the probability of event A happening, given that B happened.
is the probability of both A and B happening.
P(B) is the probability of B happening.
We have that:
So
Then
