Herbert has sold 90, 45, 103 and 68 appliances in the last four months, respectively. How many appliances will he need to sell t

Elena-2011 [213]

Answer:

The sale this month = 79

Step-by-step explanation:

Let the amount he needs to sell this month = x

$Average = \frac{sum\ of\ individual\ data\ }{number\ of\ entries}$

$Average= \frac{90\ +\ 45\ +\ 103\ +\ 68\ +\ x}{5}$

Note that number of entries = number of months = 5

To maintain an average sales of 77, the amount of sale in month 5 is determined as follows:

$77 = \frac{306\ +\ x}{5} \\cross-multiplying\\77\ \times\ 5\ = 306\ +\ x\\385 = 306\ +\ x\\x =385\ -\ 306\\x = 79$

Uh I'm confused on how to do this may someone help?

vlada-n [284]

Answer:

5

Step-by-step explanation:

Use the distance formula

$\sqrt{(x_{1}-x_{2})^{2}+(y_{1}-y_{2})^{2}}$

$\sqrt{(-2+7)^{2}+(4-4)^{2}}$

$\sqrt{5^{2}}=5$

You can also just subtract: -2-(-7) to get 5 because the y-values are the same

The cost of a package of ground beef (y) is directly proportional to its weight in ounces (x). A 14-ounce package costs $7. Writ

Sonja [21]

Answer:

$y = \dfrac{1}{2}x$

Step-by-step explanation:

The standard equation of direct variation is

y = kx

where k = constant of variation

We start with

y = kx

Since we are give one ordered pair, we use its coordinates for x and y, and we solve for k. We are told that when x = 14 ounces, y = $7.

7 = k * 14

k = 7/14

k = 1/2

Now that we know k = 1/2, we can write the direct variation equation:

$y = \dfrac{1}{2}x$
