The slope of a line can be found, given two points, as follows:
So this slope tells us the direction of a line and represents the vertical change divided by the horizontal change.
It is -1, at least thats what i got i hope this helped
Answer:
The remaining amount in the person's wallet is $30.
Step-by-step explanation:
We are given that a person left the house to go shopping with $240.00 in his wallet, and he spent 2/3 of this amount in the supermarket, then spent 1/4 of what was left in the pharmacy. At a stop at the butcher shop, he left 1/2 than he had left.
And we have to find the remaining money in the wallet after making all these above expenses.
At the starting, the amount of money in the person's wallet = $240
Amount of money spent in the supermarket =
=
= = $160
So, now the amount of money left with him = $240 - $160
= $80
Amount of money spent in the pharmacy =
= = $20
So, now the amount of money left with him = $80 - $20
= $60
Now, Amount of money spent at the butcher shop =
= = $30
So, now the amount of money left with him = $60 - $30
= $30
Hence, the amount of money remaining in the person's wallet is $30.

Answer:
a) 20
b) Variance 16, standard deviation 4
Step-by-step explanation:
For each question, there are only two possible outcomes. Either you guesses the answer correctly, or you do not. The probability of guessing the answer of a question correctly is independent of other questions. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The variance of the binomial distribution is:
The standard deviation of the binomial distribution is:
100 questions
So n = 100.
You guess
5 options, one correct. So
(a) What is your expected score on the exam?
(b) Compute the variance and standard deviation of x.
Variance:
Standard deviation:
