Total pedestrian deaths = 179
Total number of deaths that involved intoxicated
driver = 96 + 40 = 136
Two accidents are randomly selected without replacement,
thus;
Probability = desired outcome / total number of
outcome
<span>Probability = (136/179) x (135/178) = 0.7597x0.7584 =
0.5761</span>
I'm sure you already know the axis which is x= -2. The vertex is (-2,-9). You can use the graph or solve to find the vertex. I hope this helpful.
Answer:
(4b-9) (4b+9)
Step-by-step explanation:
16b^2 – 81
This is the difference of squares
(a^2 -c^2) = (a-c) (a+c)
a^2 = 16b^2 so a= 4b
c^2 = 81 so c = 9
(16b^2 – 81) = (4b-9) (4b+9)
Answer:
The price of the cupcakes
Step-by-step explanation:
The expression represents the price of the cupcakes. D represents the dollar amount. If you were to do d-7 then you would get the price of the cake but since it's d+7 it would be the cupcakes
Negative numbers aren't in a solution set because in equations and inequalities you have to multiply and divide and a positive number divided by a negative number will be a negative number. Positive divided by positive will be positive. Negative divided by negative will be positive. So that's why negative numbers aren't a solution to any set or equation.
hope this helps
