Answer:
38
Step-by-step explanation:
40 x 95/100 = 38
95 is the amount
40 is the percent that this item is off by
100 is the maximum percent the item can be off by
Another example to prove this
40 percent * 95 =
(40:100)* 95 =
(40* 95):100 =
3800:100 = 38

Answer:
x = 1
Step-by-step explanation:
The line of symmetry is defined as the x value of the vertex of a parabola.
To find the vertex of a parabola, we need to convert to vertex form.
Vertex form looks like this:
, where -h is the x value of the vertex and k is the y value of the vertex.
H is also defined as 
where a is the coefficient of x squared and b is the coefficient of the x term.
The coefficient of the x squared term is 1 and the coefficient of b is -2.
Plugging in, we get 
, which is equal to 1. This can then be plugged into the equation as
, but k doesn't matter because all we need is the x-term. Now, our x-term is negative h, which is negative negative one, which is positive one. Therefore, our answer is x = 1.
Answer:
82 wheels
Step-by-step explanation:
7(2) + 9(4) + 8(4) = x
14 + 36 + 32 = x
82 = x
The frequency is how often something occurs. Here 15. It occurred 15 times that the participants scored in the interval given.
The relative frequency (expressed as a percent) looks at how often something occurred relative to the overall occurrences. Here 15/60 = 1/4 = 25%
The relative frequency is 25%
