Answer:
0.1728
Step-by-step explanation:
We know that the random variable, X, arises from a binomial experiment, besides n = 14 and p = 0.13, so, q = 1 - p = 1 - 0.13 = 0.87. For a particular value x, we can compute the probability P(X = x) as 
, therefore, 
. You can copy and paste the next instruction in excel to find the answer =COMBIN(14, 3)*0.13^3*0.87^11
Answer:
B. 236.3
Step-by-step explanation:
Population density can be found by dividing the number of people by the area of the land.
number of people / land area
The population is 20,510 people and the area is 86.8 square miles.
20,510 people / 86.8 square miles
Divide 20,510 by 86.8
236.290323 people /square mile
Round to the nearest tenth. The 9 in the hundredth place tell us to round the 2 to a 3 in the tenth place.
236.3 people/ square mile
There are 236.3 people per square mile and B is correct.
Answer:
x=11
Step-by-step explanation:
We would add 8 to both sides of the equation, leaving us with x=11
c= number of cars
9 more than the number of cars
=c+9
Assuming you want the slope, the answer is -2/-3.
X-change: -2
Y-change: -3
X-c/Y-c = -2/-3
If -2/-3 is not an answer, try 2/3 or .666 (infinite 6s).
