First, find the mean. You'll need it to compute the variance.
The variance of the sample is then computed with the formula
The standard deviation is the square root of the variance, so
The ratio is 3:4 vehicles to people. So we need to find out what each unit is X:
4x = 17600
x = 4400
Now take the 4400 and multiply it by 3 to find the number of cars.
3 * 4400 = 13200 vehicles.
Graph of f(x-3) is compressed by a factor of horizontally of f(x).
<u>Step-by-step explanation:</u>
We have, the graph of f(x)= , on replacing f(x) by f(x-3) we get:
= .Below shown are the images for graph of f(x) and f(x-3). Both are functions are exponential , and so having exponential graph but f(x-3) is compressed by a factor of horizontally . Domain and range of both functions are same i.e. F(x) & f(x-3) domain & range are same , just difference in graph : .
Answer: 480 sq ft
Step-by-step explanation:
for two rectangles on right do 8*16 =128*2 = 256
the rectangle on the right is also 128
total of all rectangles is 384 ft
now for the triangles
formula: 1/2 b*h
1/2 * 16*6 = 48
multiply that by 2 for both triangles
you have 96
add that to total and you get
480 sq ft
Answer:
-11/24
