Which relation defines y as a function of x?
UkoKoshka [18]

Answer:

A function is a relation in which each input has only one output. In the relation, y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y.

Step-by-step explanation:

For every x there is exactly one y value. We can forgive a function if some values of x do not have a y, but if there is more than one y for even one value of x, then the relation is not a function.

Ksenya-84 [330]

Answer:

3. Standard deviation is the square root of the variance.

4. Standard deviation is useful because it has the same units as the underlying data.

Step-by-step explanation:

3. In statistics, the dispersion in a given data with respect to its mean distribution can be determined or measured by standard deviation and variance. The standard deviation of a distribution can also be determined as the square root of variance.

4. Standard deviation is measured in the same units as that of the original data. Thus it has the same units as the underlying data.

A rectangular rug has an area of 84 square feet. If its length is 2 feet more than twice its​ width, find the dimensions of the
weeeeeb [17]

L=2W+2

W=(L-2)/2

A=LW, using W from above makes this

A=L(L-2)/2

2A=L^2-2L

L^2-2L-2A=0, given A=84

L^2-2L-168=0

(L-14)(L+12)=0, since L>0

L=14

The length of the rug is 14 ft

(W=(L-2)/2=6 ft)

Find the product and write in lowest term. Give me an integer or simplified fraction.<br> 7/54×27/35
wariber [46]

The product of given expression is \frac{1}{15} \text{ or } 0.0667

<em><u>Solution:</u></em>

Given that we have to find the product and write it in lowest term

Given expression is:

\frac{7}{54} \times \frac{27}{35}

Let us first find common factors of numerator and denominator so, thet simplification becomes easier

54 = 27 \times 3\\\\35 = 7 \times 5

Substituting these in above expression, we get

\rightarrow \frac{7}{27 \times 3} \times \frac{27}{7 \times 5}

Cancel the common factors in numerator and denominator

\rightarrow \frac{1}{15}

In decimal form, we get

\rightarrow \frac{1}{15} = 0.0667

Thus the product of given expression is \frac{1}{15} \text{ or } 0.0667
