horsena [70]

Answer:

Mean Absolute Deviation (MAD): 8.5

Step-by-step explanation:

Xmean = (28 + 32 + 47 + 16 + 40 + 35 + 38 + 54)/8  = 290/8

Xmean = 36.25

MAD =

(28 - 36.25) + (32 - 36.25) + (47 - 36.25) + (16 - 36.25) + (40 - 36.25) + (35 - 36.25) + (38 - 36.25) + (54 - 36.25)  divided by 8

a break down of each ( )

(8.25) + (4.25) + (10.75) + (20.25) + (3.75) + (1.25) + (1.75) + (17.75)  divided by 8  =  68

then you take 68/8 = Mean Absolute Deviation  8.5

Please help with this math question (:

Because there are more than 2 lengths for the sides and because the small triangle faces are right angles we will use this formula:

V=(1/2)bhl
which is equivalent to V=Al  (A=(1/2)bh and A is Area)

b=12in
h=35in
l=40in

A=(1/2)•12in•35in
A=(1/2)•420in
A=210in^2

V=Al
V=(210in^2)•40in
V=8400in^3

Making your answer D. 8400 inches cubed

A group of biologists found a total of 15 loggerhead turtle nests along a beach during a certain season. This was 20% of the tot
Andre45 [30]
20% also equals 1/5, right?

So in order to find the total number of turtle nests, just find 5/5, or multiply 15 by 5.

15 x 5 = 75

There were 75 total nests
