Answer:
I apologise, my device only allows me to see the first screenshot.
A: The general trend is an increase through the graph.
B: The median of the data is 5.
C. The mean of the data is 4.7
D. The median would not be affected, but the mean would increase.
Step-by-step explanation:
Answer:
And we can find the individual probabilities like this:
And replacing we got:

Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Solution to the problem
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
For this case we want this probability:
Since one fourth of the total number 12 is 12/4 =3
We can find this probability using the complement rule:
And we can find the individual probabilities like this:
And replacing we got:
Of course!
So basically division is finding out how many times a number goes into the other number. In this case we are trying to see how many times 4 goes into 67.
4 goes into 67 16.75 times.
Since we are estimating the answer is a little different.
If we are rounding the the nearest tenth the answer would be 16.8.
If you are round the the nearest whole number the answer is 17.
I hope this helps!
Answer:
Option (C)
Step-by-step explanation:
Let the relation between amount of money (m) and Time (t) is represented by the equation,
m = ct + b
Where c = Investment per week
b = Ben already had the amount before investment
From the question,
c = $5 per week
b = $100
Therefore, equation will be,
m = 5t + 100
If duration of the investment 't' = 8 weeks
Amount in the account after 8 weeks,
m = 5(8) + 100
m = $140
Option (C) is the correct option.
