Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
and
So, we need to find,
(∵they are independent events .)
So, option 'D' is correct.
From the slope formula
(5-1)/(-3-1). slope = -1.
Finding the y intercept (b in this case)
y = -x + b
We plug in one of the points we have to solve for b (I use (1,1) you can use (-3,5) if you want)
y = -x + b
1 = -(1) + b
1 = -1 + b
2 = b
So now we have our formula
y = -x + 2
Answer:
x = 58°
Step-by-step explanation:
Fact 1) Recall the fact that angles in a triangle add to 180°
Fact 2) Recall the fact that angles on a straight line add to 180°
The first angle we can work out is BAC using fact 2
114 + ? = 180
? = ( 180 - 114 )
? = 66
∠ BAC = 66
Now that we have angle BAC we can utilise the fact angles in a triangle add to 180°, so we can set this equation up
x + 66° + 56° = 180°
x + 122° = 180°
x = ( 180 - 122 )
x = 58°
