e number of stamps Jasmine will have at the end of x months. How many stamps was Jasmine given, and how many stamps will she buy every month?
Jasmine was given 65 stamps, and she will buy 5 stamps every month.
Jasmine was given 60 stamps, and she will buy 65 stamps every month.
Jasmine was given 5 stamps, and she will buy 60 stamps every month.
Jasmine was given 60 stamps, and she will buy 5 stamps every month
Jasmine was given 65 stamps, and she will buy 5 stamps every month.
Jasmine was given 60 stamps, and she will buy 65 stamps every month.
Jasmine was given 5 stamps, and she will buy 60 stamps every month.
Jasmine was given 60 stamps, and she will buy 5 stamps every month

Answer:
Option (4)
Step-by-step explanation:
If we draw a graph against x(Number of months) and y(Number of stamps),
We will get a straight line.
Let the equation of straight line be,
y = mx + b
Here, m = Stamps purchased per month
b = Jasmine was given stamps initially
From the table attached,
m = = 5 stamps per month
Therefore, equation of the line will be,
y = 5x + b
Since, a point (1, 65) lies on this line,
65 = 5(1) + b
b = 60
That means she was given 60 stamps initially.
Option (4) will be the answer.

Answer:
Theoretical probability = 50%
Experimental probability varies.
See below for explanation.
Step-by-step explanation:
This is a problem on theoretical and experimental probability. The results obtained would enable you understand their differences.
The theoretical probability is the result that is expected to happen, but it isn't always what eventually happens.
The theoretical probability of a coin landing on heads is ½ or 50%. This is same for tails.
The experimental probability is the probability obtained from carrying out the experiment. As this is the result of what actually happens, the experimental probability could be lesser or greater than or equal to 50%.
You are required to carry out the experiment. This is because the result would vary from person to person as well as from one experiment to the other.
First, make a table for the number of trials, outcome (head and tail each) and the frequency. Pen down the result for each of the experiment carried out. You can use a tally to make it easy for compilation.
See attachment for table.
Theoretical probability of 10 trials:
Head= 5, tail = 5
Theoretical probability of 30 trials:
Head= 15, tail = 15
Theoretical probability of 100 trials:
Head= 50, tail = 50
It all amount to 50% each
So do your experiment and record the results. Afterwards compare your result which is the experimental probability
for head and tail with the theoretical theoretical.
Also compare your result with that of your classmate.
