Step-by-step explanation:
Find P(X=4)
By doing 4C4* (0.15)^4*(0.85)^0
Find P(X=1, 2,3) by doing 1- Ans you get for P(X=4)
The answer is A
Multiply the 2nd equation by -2
-2x -12y = -8
Then add it to the 1st equation
-9y = -6
y = 2/3
By substituting in the 1st equation
2x + 3(2/3) = 2
2x = 0
x=0
Answer:
y- intercept = - 13 , x- intercept = 
Step-by-step explanation:
To find the y- intercept, substitute x = 0 into the equation and solve for y
y = 5(0) - 13 = 0 - 13 = - 13 ← y- intercept
To find the x- intercept substitute y = 0 into the equation and solve for x
0 = 5x - 13 ( add 13 to both sides )
13 = 5x ( divide both sides by 5 )
= x
x- intercept =
= 2
= 2.6
Answer:
She multiplies each number by three. So 54×3=162
Answer:
Y=x(5)+120
Step-by-step explanation:
Y= the money you have to pay for the party
X(5)= you multiply x by 5
+120= you add the fee
