20 = 0.6*x
x = 20/.6
x = 33.33

The regular price of the jeans is $33.33

What is the slope of the line that passes through the points (-4, -1) and (4, 5)?
andreyandreev [35.5K]

Answer:

3/4

Step-by-step explanation:

Since we have two points, we can use the slope formula

m = ( y2-y1)/(x2-x1)

   = ( 5 - -1)/( 4 - -4)

   = ( 5+1)/(4+4)

   = 6/8

   = 3/4

Exercises 1–5
Degger [83]

Answer:  The estimated value for population mean rating based on these ten sampled ratings is 7.3 .

Step-by-step explanation:

Given : A random sample of size ten produced the following ratings in the computer games rating example in the  last lesson:

12, 5, 2, 4, 1, 4, 18, 10, 1, 16.

Let x denotes any value in the above data.

{\sum_{i=1}^{10}x_i}{10}=73

We know that the sample mean(\overline{x}) is the best estimate to the population mean(\mu).

Sample mean=\overline{x}=\dfrac{\sum_{i=1}^{n}x_i}{n}

Here , n= 10

\overline{x}=\dfrac{\sum_{i=1}^{10}x_i}{10}

\overline{x}=\dfrac{73}{10}=7.3

Therefore , the estimated value for population mean rating based on these ten sampled ratings= 7.3
