Answer:
The statement is true about whether A and B are independent eventa is fourth option:
A and B are not independent events because P(A/B)=0.375 and P(A)=0.25
Step-by-step explanation:
Let A be the event that the person rides the bus to school, then:
P(A)=75/300
P(A)=0.25
Let B be the event that the person has 3 or more siblings, then:
P(B)=24/300
P(B)=0.25
P(A/B)=9/24
P(A/B)=0.375
Like P(A/B)=0.375 is different to P(A)=0.25 the events are not independent
Answer. Fourth option:
A and B are not independent events because P(A/B)=0.375 and P(A)=0.25
16-A 18-B 19-D (not 100% sure on 16)
Answer:
She was wrong because if you were to find the quotient it would be 2 because if it were to be 3 it'll look like 6 divided by 18= 3. so what she has to do is find what times 6 equals 2 and that'll be 6 divided by 12= 2

Answer:
The equation of Grant's path is y = 4 - x over 2 ⇒ 2nd answer
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
- m is the slope of the line
- b is the y-intercept (value y at x = 0)
The formula of the slope of a line is 
∵ Grant's path is a line from point A to point B
∴ The equation of AB represents Grant's path
Lets find the slope of AB using the formula of the slope above
∵ A = (8 , 0)
∵ B = (-4 , 6)
∴ 
= 8 and 
= -4
∴ 
= 0 and 
= 6
∵ 
∴ 
Substitute the value of m in the form of the equation
∵ y = m x + b
∴ y = 
x + b
∵ b is the value of y at x = 0
∵ y = 4 at x = 0 ⇒ from the figure
∴ b = 4
∴ y = x + 4
We can write x as 
∴ y = + 4
- Switch the two terms of the right hand side
∴ y = 4 - 
The equation of Grant's path is y = 4 -
