Answer:
95.4% of family vehicles is between 1 and 3 years old.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 2
Standard Deviation, σ = 6 months = 0.5 year
We are given that the distribution of age of cars is a bell shaped distribution that is a normal distribution.
Formula:
P(family vehicles is between 1 and 3 years old)
95.4% of family vehicles is between 1 and 3 years old.
Answer:
The other endpoint of the line segment = (-1, -3)
Step-by-step explanation:
A segment has:
Let (x, y) be the other endpoint of the line segment
Therefore, the other endpoint of the line segment = (-1, -3)

Hope this helps
First write it in vertex form :-
y= a(x - 2)^2 + 3 where a is some constant.
We can find the value of a by substituting the point (0.0) into the equation:-
0 = a((-2)^2 + 3
4a = -3
a = -3/4
so our equation becomes y = (-3/4)(x - 2)^2 + 3
Answer:
12 and 1/4
Step-by-step explanation:
This is a fairly simply problem all you have to do is all all the fractions given. So we get the equation 4/8 + 5/8 + 5/8 + 1 1/8 + 1 1/8 + 1 4/8 + 1 4/8 + 1 4/8 + 1 6/8 + 2. This makes the equations easy since all the denominators are the same. First we must make all the fractions improper fractions. This will make the equation 4/8 + 5/8 + 5/8 + 9/8 + 9/8 + 12/8 +12/8 + 12/8 + 14/8 + 16/8. Then we can add all the values together and we get 98/8 which simplifies to 12 2/8 which further simplifies to 12 and 1/4.
