Write the Slope- Intercept equation of the line that passes through the given point and is perpendicular to the given line (0, -
damaskus [11]

Answer:

y+4=-3(x+0) or y=-3x-4

Step-by-step explanation:

so you have to make it in form y=mx+b

that would be y=1/3x-2/3

for a perpendicular line, you would need to find the opposite reciprocal of the slope

3/1 or 3 would be the reciprocal, so to make it opposite would be -3

So it would be y-y1 = m(x-x2)

fill it in with the coordinates (0,-4)

y+4=-3(x-0)

to get it to slope intercept form you have to simplify, and after that you get y=-3x-4

Some teenagers collected trash for a beach cleanup. The data for the number of pounds of trash collected by each teenager are sh
Mumz [18]

Answer:

4.66

Step-by-step explanation:

We are given the following data

26, 26, 21, 22, 20, 25, 35

Step 1

We find the Mean

Mean = 26+ 26+ 21+ 22+20+25+ 35/7

= 175/7

= 25

Step 2

We find the Standard Deviation

The formula for Standard deviation that we would use is the Population Standard deviation, this is because the data given above is the data of the number of pounds of trash collected by each teenager

= √(x - Mean)²/n

= √(26 - 25)²+( 26 - 25)²+ (21 - 25)²+ (22 - 25)² +(20 - 25)²+(25 - 25)²+ (35 - 25)²/7

= √152/7

= √21.7142857

= 4.65985898

Approximately = 4.66
