Answer: 46


--------------------------------------------


Step 1 is to compute the value of r(-4)


r(x) = -5x-5

r(-4) = -5(-4)-5 ... replace every x with -4

r(-4) = 20-5

r(-4) = 15


Now we can do replacements. We can replace the "r(-4)" with 15 because of the last equation above.


So we go from s(r(-4)) to s(15)


Plug x = 15 into the s function


s(x) = 3x+1

s(15) = 3*15+1

s(15) = 45+1

s(15) = 46


In the end,

s(r(-4)) = 46

If a building was placed at coordinates (-5,5), what would be the new coordinates if rotated 270° counterclockwise around the or
Brums [2.3K]

The rule for a 270° counterclockwise rotation is (x, y) ---> (y, -x).

So if you rotated (-5,5) 270° counterclockwise around the origin the new coordinates would be (-5,-5).

Hope this Helps!!

Rufina [12.5K]

Answer:

To find the mean, you have to add all numbers together and divide them by the number of data points.

let me show what I mean:

The heights of the dogs are 600,470,170, 430,300.

Step-by-step explanation:

600+470+170+430+300.

1970.

Now we have to divide 1,970 by 5 ( because we are given 5 data points)

The mean is:

1970/5=394

Variance: First, arrange the data from least to greatest.

s2 = 27130

Standard Deviation: 164.71187
