Easy,

$1394+$124=$1518

This is the original selling price, but $194 was taken off, resulting in $1394.

Now to find Percent Markdown, use this formula:

Percent Markdown= \frac{Markdown Amount}{Selling Price} *100

To find Markdown:

Markdown=Original Selling Price-Reduced Price

Now plug in what you have.

Markdown=$1518-$1394=
M=124

As we already knew, the Markdown is 124.

Now,

<span>Percent Markdown= </span>\frac{124}{1394} *100
PM=0.088952654*100
PM=8.9 (rounded)

Thus, the percent increase, is 8.9%.

What is the population standard deviation of this data set?*
Minchanka [31]

Answer:

C)  2

Step-by-step explanation:

step 1:  Find mean of data set

2+4+4+5+7+8 = 30

30/6 = 5

Mean = 5

step 2: subtract each data value from the mean and square it

5-2 = 3;   3² = 9

5-4 = 1;   1² = 1

5-4 = 1;   1² = 1

5-5 = 0;   0² = 0

5-7 = -2;   (-2²) = 4

5-8 = -3;   (-3²) = 9

Add the squared results:

9+1+1+0+4+9 = 24

Divide 24 by 6 to get the Variance of 4

Take the square root of the Variance to get the Standard Deviation

\sqrt{4} = 2

Zarrin [17]
Since the number before the number in the tenth place (7) is greater than 5 (8), you will be rounding up. So your answer is 9.80

Pls help I don't understand:
sineoko [7]

Answer:

Part a) T(d)=2d+30

Part b) T(6)=42\ minutes

Step-by-step explanation:

Part a) Write an equation for T (d)

Let

d ----> the number of days

T ---> the time in minutes of the treadmill

we know that

The linear equation in slope intercept form is equal to

T=md+b

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have

The slope or unit  rate is

m=2\ \frac{minutes}{day}

The y-intercept or initial value is

b=30\ minutes

substitute

T(d)=2d+30

Part b) Find T (6), the minutes he will spend on the treadmill on day 6

For d=6

substitute in the equation and solve for T

T(6)=2(6)+30

T(6)=42\ minutes
