Answer:
38.13 m^2
Step-by-step explanation:
the area of a triangle =b*h/2
b=base
h=height
area triangle=(4m*3m)/2=(12m^2)/2=6m^2
the area of a rectangle =b*h
b=base
h=height
area of a rectangle=6m*3m=18m^2
area of a semi circle=(pi*r^2)/2
r=radius
area of a semi circle==(3.14*(3m)^2)/2=14.13m^2
area of the figure=6m^2+18m^2+14.13m^2=38.13m^2
the answer is 38.13m^2
4583.33333333 should be the answer
Answer:
The need to sample 76 days.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
How many days do they need to sample
We need to sample n days.
n is found when M = 300.
We have that 
So
Rounding up
The need to sample 76 days.
Animators can create mountains using fractal geometry.
They create these mountains by breaking large triangles into smaller and smaller triangles, as a result, these large triangles end up looking like mountains.
An animator became a millionaire because he discovered this. He sold his mountain animations to air travel companies who wanted to place photographs of planes behind mountains in their advertisements.
It would've been expensive to take photos of planes behind real mountains, so these air travel companies decided to buy this animator's animations of mountains in order to save money.
What happened to this animator? Well he got hired by Pixar to help create the movie Toy Story and became even wealthier.
