Jason paid $15.50 for 3 slices of pizza and 2 burgers. Susan paid $20 for 1 slice of pizza and 4 burgers. Write a system of equa
tions and then determine the cost of each Slice of pizza and the cost of each burger.(Do Not give the equation as your answer).
:Each slice of pizza cost$?
:Each burger cost$?
:Each slice of pizza cost$?
:Each burger cost$?
1 answer:
Answer:
Each slice of pizza cost $2.2
Each burger cost $4.45
Step-by-step explanation:
Let
x -----> the cost of one slice of pizza
y ----> the cost of one burger
we know that
<em>Jason</em>
-----> equation A
Susan
-----> equation B
Solve the system of equations by graphing
Remember that
The intersection point both graphs is the solution sof the system of equations
The solution is the point (2.2,4.45)
see the attached figure
therefore
Each slice of pizza cost $2.2
Each burger cost $4.45

Answer:
Women has better study habit than men.
Step-by-step explanation:
For knowing who has better study habits and attitudes toward learning we have to find the mean of both the women and men data.
The first step is that we only take first 18 values of both women(X) and men(Y) data, to make them of same length
Mean is used to measure the central tendency of data which represents the whole data in the best way. It can be found as the ratio of the sum of all the observations to the total number of observations.
Calculating all values:
= 141.0556
= 121.25
Thus, women has better study habit than men. Since Mean of X is larger than Mean of Y.
