Answer:
the first one
Step-by-step explanation:
if you simplify 10/2 it is 5. there is already a 5 as an x value, so that means this isn't a function.
2y = 8x + 6
y = 4x + 3
The graph is a straight line passing through points (0, 3) and (-3/4, 0) with slope = 4.
Answer:
distance between two cars in a straight line = 4.12 miles
Step-by-step explanation:
The North and East make a right angle and if you make a straight line between the two cars you will make a right angled triangle.
Now we can use Pythagoras theorem to calculate the distance between two cars in a straight line.
p = 1
b = 4
h = ?
Using Pythagoras theorem
h² = p² + b²
h² = 1² + 4²
h² = 1 + 16
h² = 17
h = sqroot (17)
h = 4.12 miles

Answer: The value of P(A or B) is 0.8.</h3>
Step-by-step explanation: We are given P(A)=0.6 , P(B)=0.3 and P(A and B)=0.1.
P(A and B)=0.1 could be written as P(A∩B) = 0.1.
We need to find P(A or B) that is P(A∪B) = ?
We know formula,
P(A∪B) = P(A) + P(B) - P(A∩B)
Plugging values in formula, we get
P(A∪B) = 0.6 + 0.3 - 0.1
P(A∪B) = 0.9 -0.1
P(A∪B) = 0.8.
<h3>Therefore, the value of P(A or B) is 0.8.</h3>
