The slope of line passing through the given points is: -1/2

Step-by-step explanation:

Given points are:

(x1,y1) = (-8,-1)

(x2,y2) = (-6,-2)

Slope is defined as the steepness of a line.

It is denoted by m.

The formula for slope is:

m = \frac{y_2-y_1}{x_2-x_1}

Putting the values

m = \frac{-2-(-1)}{-6-(-8)}\\= \frac{-2+1}{-6+8}\\=\frac{-1}{2}

The slope of line passing through the given points is: -1/2

Keywords: Slope, steepness

Evaluate the following expression:
Maurinko [17]

Answer:

1

Step-by-step explanation:

{6}^{2} - 7(8 + 6 -  {3}^{2})

Using BODMAS we'll have to solve what is in the bracket first

=  {6}^{2}  - 7(14 - 9) \\  =  {6}^{2}  - 7(5) \\

Multply -7 by 5 still using the rule of BODMAS

=  {6}^{2}  - 35 \\  = 36 - 35 \\  = 1

Here are the prices of five new pairs of hockey skates, in dollars: 59, 60, 65, 99, 175. The standard deviation is about $49. If
Phoenix [80]

Answer:

The standard deviation of the new data will be increased as compared to the previous standard deviation of the data.

Step-by-step explanation:

The prices are given to be : 59, 60, 65, 99, 175

Standard deviation = $49

Now, if we add or subtract any constant value to each of the terms then the standard deviation remains unchanged.

But, we add a new price in the given data that is $450

\text{New standard deviation = }\sqrt{\frac{\sum (\bar{x}-x_i)^2}{n}}\\\\\bar{x}\text{ is the mean of data after adding 450 and}\\x_i\text{ are the price values of the sample data}

Hence, Standard deviation is calculated to be 139.5

Therefore, the standard deviation of the new data will be increased as compared to the previous standard deviation of the data.

Problems with Equations:
Bas_tet [7]

Answer:

x = 11

The value "11" makes the equation true.

Bed &amp; Bath, a retailing company, has two departments—Hardware and Linens. The company's most recent monthly contribution for
kykrilka [37]

Answer:

By eliminating Linens department net operating income fell by $574,800.00

Step-by-step explanation:

The question requires that the monthly contribution income statement be prepared when the Linens is closed or eliminated,incorporating the unavoidable fixed costs of $373,000 as well as the fall in sales of Hardware by 15%.

             Monthly Contribution Income Statement:

Sales($3,110,000)*(1-15%)                               $2,643,500.00  

Variable expenses($858,000)*(1-15%)          ($729,300.00)

Contribution margin                                        $1,914,200.00  

Fixed expenses($1,480,000+$373,000)      ($1,853,000.00)

Net operating income                                        $61,200.00  

Reduction in net operating=$636,000-$61,200.00=$574,800  

Alternatively:

Lost contribution from closing Linens department    $674,000.00

Lost contribution from Hardware(15%*$2,252,000)   $ 337,800.00  

Total lost contribution                                                   $1,011,800.00  

Less avoidable fixed costs($810,000-$373,000)         ($437,000.00)

Reduction in profits company-wide                                $574,800.00
