There are 11 pets in a cute pet competition, 6 cats(C), 3 dogs(D) and 2 gerbils(G). Three winners will be chosen for first second and third prize. A winner can only get
one prize. Sample space is (C1, C2, C3, C4, C5, C6, D1, D2, D3, G1, G2]
a) What is the probability that C5, G2 and D1 are chosen in that order?
b) What is the probability that all three chosen are C?
a) 990 b) a = 0.12
O a) 165 b 0.55
O a) 165 b) 0.12
a) 990 b 0.55

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
