What is the area of the shaded figure

Mathematics
1 answer:
Gnom [1K]3 years ago
8 0

Answer:

42 square units

Step-by-step explanation:

imagine the rectangle around the original shape, it would be LxW which wold be 9 x 6 = 54. Then if you find the area of the two triangles cut out of the left and right sides, each triangle area is 1/2 base x height, which is 1/2(6x2)=1/2(12)=6 and x2 for 2 triangles and that = 12.

Now subtract 54-12=42 sq. units shaded.

Tanzania [10]

Answer:

17.11%

Step-by-step explanation:

since 43.2 months is the mean, and the standard deviation is 7.7 months

that means if we take the z score:

z=(36-43.2)/7.7

now that we know how many standard deviations you are away from the mean: -0.9351

using the zscore table you can find the proportion, or you can use the calculator if you have one that can do that.

you get 0.1711 which in percentages is 17.11%

Well I don't know ! 
Let's take a look and see:

The idea is that there could be more than one way
for a roll of the dice to land with the same number.  

-- If the sum is from 1-4, you get the point.
There are  6  different ways for a roll of the dice to come up 1-4.

-- If the sum is from 5-8, Adam gets the point.
There are  20  different ways for a roll of the dice to come up 5-8.

-- If the sum is 9-12, Lana gets the point.
There are  10  different ways for a roll of the dice to come up 9-12.

-- The game is not fair to all three of you.
-- Lana has a distinct advantage over you.
-- Adam has a big advantage over Lana.
-- Adam has an even bigger advantage over you.
-- You are at a big disadvantage.  (Notice that one of your
numbers ... 1 ... can never come up unless one of the dice
falls off of the table.)
