Answer:
The correct option is B) zero x = -2.
Step-by-step explanation:
Consider the provided graph y = x + 2
The zeros of a function are the point on which graph intersects the x axis or we can say the value of x when y = 0.
Substitute y = 0 in the provided equation.
0 = x + 2
x = -2
The coordinate is (-2,0). Also the zero of the graph is at x = -2 because it follows the definition of zeros.
Now substitute x = 0 in the provided equation.
y = 0 + 2
y = 2
The coordinate is (0,2).
Now, draw a line passing through the point (-2,0) and (0,2).
The required line is shown in figure 1.
Now consider the provided options only option A and B have the same graph.
But the correct option is B as the zero of the option B is x = -2.
Hence, the correct option is B) zero x = -2.

Answer : The fraction empty container is,
Step-by-step explanation :
As we are given that:
The capacity of container = 60 mL
In the given figure, the container is filled with 25 mL.
That means,
60 - 25 = 35 mL container is empty.
Now we have to calculate the fraction of it is empty.
The fraction of it is empty =
The fraction of it is empty =
The fraction of it is empty =
Therefore, the fraction empty container is,
The mean deviation of the ratings is 4.12
<em><u>Explanation</u></em>
The ratings of the ten experts are: 34, 35, 41, 28, 26, 29, 32, 36, 38 and 40
So, the mean of all ratings
<u>The formula for Mean deviation</u> , where
is the given data from
to
,
is the mean of the data and
is the total number of data. So.....
So, the Mean deviation
