Answer/Step-by-step explanation:

Quotient is simply the ratio of the first numerator to the second numerator:

Let's $\frac{x_1}{y}\;and\;\frac{x_2}{y}$ are two fractions in same terms.

Thus, $\frac{x_1}{y}\div\frac{x_2}{y}$ {Divided by a fraction is equal to multiplied by its reciprocal}

= $\frac{x_1}{y}\times\frac{y}{x_2}$

Quotient is simply the quotient of their numerators.

Example could be:

$\frac{2}{7}\div\frac{3}{7}$

$\frac{2}{7}\times\frac{7}3}$

$\frac{2}{3}$

2 is first numerator and 3 is the second numerator.

The box plots below show attendance at a local movie theater and high school basketball games:

cricket20 [7]

The standard deviation is a better measure of spread for movies than it is for basketball games.

A box plot is a graphical rendition of statistical data based on the minimum, first quartile, median, third quartile, and maximum.

As, Movies is more centric to mean and not skewed on a particular side whereas basketball games is not centric to mean but is skewed right then left.

Now, Standard deviation just measures the deviation or spread with respect to mean of collected data.

So, In the movies the data is more collected. Thus standard deviation is best suited for movie data.

Now, interquartile range. IQR relies on if the data is skewed.

So, in the basketball data the standard deviation will not give the information.

Hence, the standard deviation is a better measure of spread for movies than it is for basketball games.

If the fraction 414/x-10 is equivalent to -23 , find the value of x. Show your work. Use reasoning to find x.

NemiM [27]

Answer:

x = -8

Step-by-step explanation:

Solve for x by getting rid of the fraction.

414/(x-10) = -23

414 = -23(x-10)

414 = -23x + 230

184 = -23x

-8 = x

Find the equation of circle (5,1) diameter 4 square root 5

stepladder [879]

Answer:

$(x-5)^2+(y-1)^2=20$

Step-by-step explanation:

<u>Equation of a circle</u>

$(x-a)^2+(y-b)^2=r^2$

(where (a, b) is the center and r is the radius)

Given:

center = (5, 1)
diameter = 4√5

Diameter = 2r (where r is the radius)

⇒ r = 4√5 ÷ 2 = 2√5

Substituting these values into the equation:

$\implies (x-5)^2+(y-1)^2=(2\sqrt{5})^2$

$\implies (x-5)^2+(y-1)^2=20$
