Determine the Mean and Variance
Equally likely implies that the data follows a uniform distribution.
So,
Where
Variance of a uniform distribution is calculated as thus;
Substitute values for a and b
Answer:
Hotel B is the least expensive
Step-by-step explanation:
Given
See attachment for clear details
Required
The least expensive
To do this, we simply divide the total cost by the number of nights to get the unit price
i.e.
Hotel A
per night
Hotel B
per night
Hotel C
per night
From the calculations above;
<em>Hotel B is the least expensive because 60 is less than 64 and 65</em>
Answer:
i.e. relation between speed-distance-time is one such situation that can be modeled using graph
Step-by-step explanation:
There are many real world examples that can be modeled using graph. Graphs are represented on co-ordinate planes, so any real world example that can be represented by use of linear equation can be represented onto a graph.
One such example, is speed-distance-time relation. Uniform speed can be represented on a graph as shown in figure.
So, the equation for speed is represented by equation as follows:
So, if we take distance on y axis and time on x axis with points as (distance,time)
(0,0) ==>
(1,2) ==>
(2,2) ==>
the following points 0,0.5,1 will be plotted on graph. Similarly, more values can be plotted by assuming values for distance and time.
Answer:
Step-by-step explanation:
First divide 10.98 by 6 then 8.92 by 4 and subtract the two answers
Answer:
Point-slope equation is
y-y1 = m(x-x1)
m is a slope, m=5/4
y1 = -5, x1 = 8
Point-slope equation is
y+5 = 5/4(x - 8).
