With replacement, each draw has a probability of
9 pink out of 18 total number of chips.
Therefore, by the multiplication rule, the probability of having both draws picking a pink is
P(pink,pink) = (9/18)*(9/18) = 81/324 [ = 1/4 ]
or
P(pink,pink) =
Answer:
k = - 3
Step-by-step explanation:
Given that x = 3 is a solution then it satisfies the equation, that is
2(3)² - 5(3) + k = 0
2(9) - 15 + k = 0
18 - 15 + k = 0
3 + k = 0 ( subtract 3 from both sides )
k = - 3
y= kx
k= y/x
k= -3/4
make the constant K the subject
The y intercept of the equation is -4. We know this because the y intercept of a linear equation always appears there in the formula.
To find the x intercept, plug 0 in for y and solve for x.
0=3x-4
<em>*Add 4 to both sides*</em>
4=3x
<em>*Divide both sides by 3*</em>
4/3=x
The x intercept of the equation is 4/3.
