To find the probability of any sample you're studying, you divide the number of objects studied by the total number of the sample. Here, we have 30,000 cars. It has been found that 222 had a defect in one of the headlight bulbs. So 222 of 30,000 cars had a defect. So the probability that any of those cars can have a defect is 222/30,000. You divide both numbers by 5 to simply, and you get 37/5000.
So the probability that any of those cars could have the defect is 37/5000, so 37 cars out of 5000 (Answer C)
Hope this Helps! :)
Hi there!
From the given information, we can infer that the inner quadrilateral has equal side lengths of x and 2x-3.
We can turn this into a mathematical equation with 1 variable.
x = 2x - 3
Subtract both sides by 2x
-x = -3
Multiply both sides by -1
x = 3
Have an awesome day! :)

Answer:
x = 8, y = -7
in coordinate form: (8,-7)
Step-by-step explanation:
first, find x using the second equation:
x - 9 = -1
add 9 to both sides of the equation
x - 9 + 9 = - 1 + 9
x = -1 + 9
x = 8
next, substitute x for 8 in the first equation:
2x - y = 23
2 * 8 - y = 23
16 - y = 23
16 - y + y = 23 + y
16 = 23 + y
16 - 23 = y
y = -7
also, I had this exact question on an assignment earlier today ahah
F(h(3))
h(3) = 3^2 + 1 = 9 + 1 = 10
f(10) = 2(10) - 1 = 19
g(f(-5))
f(-5) = 2(-5) -1 = -10 - 1 = -11
g(-11) = 3(-11) = -33
f(f(6))
f(6) = 2(6) - 1 = 12 - 1 = 11
f(11) = 2(11) - 1 = 21
I think I already did the others on a separate question.
