Answer:
Step-by-step explanation:
y - y1 = m(x - x1)
y - 5 = -9/2*(x - 4)
y -5 = -9/2x + 9*4/2
y - 5 = -9x/2 +9*2
y-5=-9x/2 + 18
y= -9x/2 + 18 +5
y= -9x/2 + 23 {y =mx+c}
Answer:
160 units.
Step-by-step explanation:
In order to find the minimum cost, we need to find the vertex of the equation since it is the lowest point of the graph. To find the vertex, we use the following equation.
x = -b/2a
In this equation, a is the coefficient of x^2 and b is the coefficient of x. So we plug in and solve.
x = -b/2a
x = -(-80)/2(.25)
x = 80/.5
x = 160

Answer: P(5A) = 0
Step-by-step explanation:
There are four aces in total in a 52 card deck. Therefore the probability of getting 5 aces can be expressed as;
P(5A) = 4/52 × 3/51 × 2/50 × 1/49 × 0/48 = 0
Therefore, it is impossible to get 5 aces from a standard 52 cards deck
