Answer:

a. the less variability it has

Step-by-step explanation:

The standard deviation is a measure of the amount of variation or dispersion of a set of values.

When your standard deviation is big your data is more dispersed.

When your standar deviation is small your mean is a representative index of your data, and there is less variability.

If there was no dispersion of the data (if all your data be the same) then the standard deviation will be 0.

I need help on how to do these types of problems
aivan3 [116]
#1 
Lets x = number of adult tickets
Lets y = number of children tickets

equation 1: 8x + 4y = 5040
equation 2: x + y = 680

solve them by using substitution
 x + y = 680 
 x = 680 - y

substitute  x = 680 - y into  8x + 4y = 5040

8(680 - y) + 4y = 5040
5440 - 8y + 4y = 5040
-4y = 5040 - 5440
-4y = -400
   y = 100

x = 680 - y
x = 680 - 100
x = 580

Answer:

There were 580 adults and 100 children at the last Miller's home basketball game.

#2
Similar to the #1

Lets x is the number of people riding school bus
Lets y is the number of people riding luxury charter bus

equation 1: x + y = 65
equation 2: 8x + 15y = 611

In the year 2000, the population of a city was 600,000 citizens. The population increases at a rate of 1.8% per year.
dem82 [27]

Answer:

a) 600,000 (1.018)ᵗ, the graph is below:

* "t" is the years. 2000 is the first year, so "t" would be 1. 2012 is the 12th year so "t" would be 12.

b) As the years go by, the population increases. The years (X), and population (Y) both increase together. The graph shows that when the years increase the population increases.

c) In 2012, which would be 12 years later, I predict the population would be around 743,232 people.
