Answer:
The answer is (-3x^3)+(9x^2)-(6x)-6
Step-by-step explanation:
Line through (a,b) with slope m is
y - b = m(x -a)
Here that's line through (a,b)=(5/3, -7) with slope m=-3/4
y - -7 = (-3/4) (x - 5/3)
Solve for y,
y + 28/4 = (-3/4) x + 5/4
y = (-3/4) x - 23/4
Look at the choices.
Answer: D
Answer:
a. 7/22
b. 28/33
c. 7/22
d. dependent events
Step-by-step explanation:
The total number of cards is given as 7 + 5 = 12.
The probability if a card being green on the first pick, P(G) = 7/12
The probability of a card being yellow on the first pick, P(Y) = 5/12
Because there is no replacement, the card are going to be short by one card. Therefore, the second pick will be like this:
P(GG) = ( 7/12×6/11)
P(GY) = ( 7/12 × 5/11)
P(YG) = ( 5/12×7/11)
P(RR) = ( 5/12 ×4/11)
a. P (G1 and G2) = ( 7/12×6/11)
= 7/22
b. P( At least one is green) = ( 7/12×6/11) + ( 7/12 × 5/11) + ( 5/12×7/11)
= 28/33
c. P(G2G1) = 7/22
d. the events are dependent. They do not give the same result.
