The local Tupperware dealers earned the following commissions last month. What was the mean commission​ earned? Round your answe
kirza4 [7]

Answer:

B. ​$ 3094.01

Step-by-step explanation:

Given observations are,

$2894.21, ​ $1777.15, ​ $2144.77, ​ $4096.37, ​ $4046.29, ​$1786.37, ​ $3296.69, ​ $4086.27, ​ $2784.22

Number of observations = 10,

Sum of the observations = 2894.21​+1777.15​+2144.77​+4096.37​+4046.29​+1786.37​+3296.69​+4086.27​+2784.22​+4027.79 = 30940.13,

Hence,

Mean = \frac{\text{Sum of observations}}{\text{Number of observation}}

=\frac{30940.13}{10}

=3094.013

\approx 3094.01

Option 'B' is correct.

Determine the intercepts of the line.<br> y=-3x+12y=−3x+12
vitfil [10]

Answer:

x-intercept=4 and y-intercept = 12

Step-by-step explanation:

To find the x-intercept, make the y=0:

0 = -3x+12

3x = 12

x=12/3

x=4

To find the y-intercept, make the x=0:

y = -3(0) +12

y = 0 +12

y = 12

Hope this helps!
