Answer:
Step-by-step explanation:
<u>Given function:</u>
<u>Initial population size is when t = 0</u>
- P(0) = 400(1.22)⁰ = 400(1) = 400
<u>The multiple of 1.22 is applied every year, so the ratio of change is:</u>
This is an exponential growth which represents 22% annual growth.
Answer: The estimated value for population mean rating based on these ten sampled ratings is 7.3 .
Step-by-step explanation:
Given : A random sample of size ten produced the following ratings in the computer games rating example in the last lesson:
12, 5, 2, 4, 1, 4, 18, 10, 1, 16.
Let x denotes any value in the above data.

We know that the sample mean
is the best estimate to the population mean
.
Sample mean=
Here , n= 10


Therefore , the estimated value for population mean rating based on these ten sampled ratings= 7.3
Side adjacent to the given angle: x
Diagonal=hypotenuse=20
cos (36° 42') =(side adjacent to angle 36° 42')/Hypotenuse
cos (36° 42')=x/20
Solving for x. Multiplying both sides of the equation by 20:
20 cos (36° 42')=20 (x/20)
20 cos (36° 42')=x
x=20 cos (36° 42')
x=20 (0.801775644)
x=16.03551288
x=16.04
Answer: Option D. 16.04
The answer would be 0,0 because the dotted line is a negative slope to the right, intersecting the y axis at 2 and the shading is below.
