QUESTION A AND B PLEASEEE I REALLY NEEDED THE ANSWER

a) A ( 7,0 )

   B ( 0,7 )

b) y = x

Step-by-step explanation:

Since the radius is 7,

So,

a)   A ( 7,0 )

     B ( 0,7 )

b) The coordinates of O are (0,0)

while M are to be founded.

Using Midpoint formula to find M

M =

M =

M = (3.5,3.5)

Now, Finding the equation of line OM

Slope = m =

Slope =

Slope =

Slope = 1

Now, the y-intercept,b

Putting M(3.5,3.5) in slope intercept equation to get y-intercept, b

=>

=> 3.5 = (1)(3.5) + b

=> b = 3.5-3.5

=> b = 0

Now, the equation becomes

=>

=> y = (1)(x) + (0)

=> y = x

This is the required equation

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %

he answer is x=1x3 because x=1 to x=3
