a garden is in the shape of a rectangle and has a perimeter of 70 yards. the length of the garden is 5 more than twice the width

scZoUnD [109]

If the length of the garden is 5 more than twice the width, then length = 2 X width + 5.
P = 70
L= 2W + 5
P = 2 X (L + W)
70 = 2 X ((2W+5) + W))
You can take the + 5 out at this point by multiplying it by the 2 outside the brackets (5 for each length)
70 - (2X5) = 2X ((2W) + W)
70 - 10 = 2 X (2W + W)
60 = 2 (3W)
60 = 2*3W
60 = 6W
10 = W
The width is 10.
So what's the length? 2W + 5
Length = 2 * 10 + 5
Length = 25.

Length is 25, width is 10.

Check: 70 = 2 (25 + 10)
70 = 2(35)
70 = 70
Correct!

The brain volumes (cm cubed) of 20 brains have a mean of 1162.8 cm cubed and a standard deviation of 127.1 cm cubed. Use the g

Free_Kalibri [48]

Answer:

- The limits are 908.6 cm^3 and 1417cm^3

- 1337.0cm^3 is in between the limits

Step-by-step explanation:

To determine the limit by taking into account the range rule of thumb, you use the fact that the limits are given by the mean plus and minus twice the standard deviation, that is:

$\overline{x}\pm 2\sigma$ (1)
