Answer:
x≤0 ⇒|x-3|+5|x| = -6x + 3
0≤x≤3 ⇒ |x-3|+5|x| = 4x + 3
x≥3 ⇒ |x-3|+5|x| = 6x - 3
Step-by-step explanation:
Check the picture below.
Your electric bill has been as follows for the past six months:
2 answers:
To find the monthly average (mean), add all the numbers up and divide the answer by the total number of numbers you added up.
July: $78.56
August: $30.21
September: $81.20
October: $79.08
November: $66.18
December: $100.75
Add all the bills up.
$78.56 +
$30.21 +
$81.20 +
$79.08 +
$66.18 +
$100.75 =
$435.98
Divide $435.98 by 6 (because you added up 6 numbers).
$435.98 ÷ 6 = $72.66

Answer:
Step-by-step explanation:
For this case we want to find this probability:
Because they want the area to the left of the value. We need to remember that the normal standard distribution have a mean of 0 and a deviation of 1.
We can use the following excel code: =NORM.DIST(-1.55,0,1,TRUE)
And we got:
The other possibility is use the normal standard table and we got a similar result.
Answer:
answer to the equation is
Step-by-step explanation:
first find the slope of the line using the two points
substitute 2 for m and use one of the points for x and y and solve for b
Now that you found b, the y-intercept, you can substitute that into the equation for your line
