Answer:
(x, y) = (452.5, -986)
Step-by-step explanation:
Dividing the first equation by 300 gives the standard form equation ...
12x +5y = 500
Dividing the second equation by 180 gives the standard form equation ...
22x +10y = 95
Subtracting the second of these equations from twice the first gives ...
2(12x +5y) -(22x +10y) = 2(500) -(95)
2x = 905 . . . . . simplify
x = 452.5 . . . . .divide by 2
The second equation tells us ...
y = (95 -22x)/10 = (95 -9955)/10 = -9860/10 = -986
The solution is (x, y) = (452.5, -986).

Answer:
But does not touch the horizontal axis.
Step-by-step explanation:
The curve of a normal distribution extends indefinitely at the tails but does not " touch the horizontal axis."
The reason for this is that the tails of the curve suggest that a variable can take on any theoretically reasonable value, although the probability of such occurrence is considerably low.
Generally, a normal distribution curve is considered to be asymptotic to the horizontal axis.
Answer:
f(4) = -11
Step-by-step explanation:
Plug in 4 for x: Note that x = 4.
f(x) = -2x - 3
f(4) = -2(4) - 3
Remember to follow PEMDAS. First, solve the multiplication, then subtract:
f(4) = (-2 * 4) - 3
f(4) = (-8) - 3
f(4) = -11
f(4) = -11 is your answer.

Using proportions, the total acceleration you would have applied to the car would be of -33 m/s².
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
For one crash, the acceleration is of -3 m/s². Hence, for 11 crashes, the total acceleration would be of:
a = -3 x 11 = -33 m/s².
