So the domain is the list of x-values that are possible on a line.

In this case since time is the x-axis, this means that he ran the race from 0 to 11 seconds, eliminating the first two options.

Now, a lot of races will have times going into the decimal places (tenths, hundredths, thousandths, etc). With integers however, they are whole numbers, and fractions and decimals are not considered whole numbers. With this info, we can eliminate the last option.

With the other three options eliminated, your answer is C. Real numbers from 0 to 11.

Each cube in this solid figure is a unit cube. What is the volume of this solid figure?

padilas [110]

Answer:

The volume of this given solid figure is 18 cubic units.

Step-by-step explanation:

Here, given the volume of 1 small cube = 1 cubic units

Now, counting the total cubes in the given solid figure, we get

Number of cubes in base row = 10

Number of cubes in middle row = 6

Number of cubes in top most row = 2

So, the total number of cubes in the figure = 10 + 6 + 2 = 18 cubes

So, the volume of 18 cubes = 18 ( Volume of 1 small cube)

= 18 x (1 cubic units) = 18 cubic units

Hence, the volume of this given solid figure is 18 cubic units.

HelloI need some assistance with this question. I provided an answer, but it was incorrect. The images are enclosed.

ycow [4]

Given:

There are given that the zeroes and degrees of the polynomial:

$\begin{gathered} \text{zeros:}-2,2,4 \\ \text{Degres:}3 \end{gathered}$

Explanation:

From the concept of a polynomial:

A polynomial has a as zero if and only if (x -a) is a factor of the polynomial.

Then,

From the given polynomial:

$f(x)=(x+2)(x-2)(x-4)$

Then,

$\begin{gathered} f(x)=(x+2)(x-2)(x-4) \\ f(x)=(x^2-2x+2x-4)(x-4) \\ f(x)=(x^2-4)(x-4) \\ f(x)=x^3-4x^2-4x+16 \end{gathered}$

Final answer:

Hence, the polynomial is shown below:

$f(x)=x^3-4x^2-4x+16$

After 3 points have been added to every score in a sample, the mean is found to be M 5 83 and the standard deviation is s 5 8. W

Maurinko [17]

Answer:

Hence the value for the mean is 80 and the standard deviation for the original sample is 8.

Step-by-step explanation:

Mean = 83-3 = 80.

Here the standard deviation didn't change = 8.
