What is the SLOPE of the LINES that passes through the points (13,1) and (-2,4 )
olga55 [171]

Answer: M= slope

M= -1/5

Step-by-step explanation:

M= the change in y over the change in x so you would do 1-4 over 13-(-2) which gives you -3 over 15 which is simplified to give you the answer which is -1/5.

Please help!
AfilCa [17]

Answer:

a.) P(HH|C)=2/5

Explanation:

Given following:

  • P(HH) = 7
  • P(C) = 10
  • P(HH ∩ C) = 4
  • P(HH ∪ C) = 13

Solving steps:

\sf P(HH|C) = \dfrac{P(HH \cap C) }{P(C)}

\sf P(HH|C) = \dfrac{4 }{10}

\sf P(HH|C) = \dfrac{2 }{5}

Find the coordinates of midpoint F.
Mice21 [21]

Answer:

The coordinates are (0,b)

Step-by-step explanation:

Here, we want to find the coordinates of the midpoint F

as we can see, F is between A and B

we proceed to use the midpoint formula

The midpoint formula is;

(x,y) = (x1 + x2)/2, (y1 + y2)/2

(x1,y1) = (-3a, b)

(x2,y2) = (3a, b)

The substitution of these values will thus yield;

(-3a + 3a)/2, (b + b)/2

= (0/2), (2b/2)

= (0, b)
