If each of them paid an extra of $4.
4 person paid $4 x 4 = $16 extra
The $16 is the share of the 5th person, which is also each person's share.
$16 x 5 = $80.
Answer: The total bill is $80.
Answer choices a, c, and e is correct.
28 + 58 + 94 = 180
Answer:20 pieces
Step-by-step explanation:
8 7/8=71/8
71/8 *4/7(reciprocal of 1 3/4)= 284/56= 20.2867
The claim of Miguel is correct, as the two events are independent because P(NF|PB) = P(NF).
<h3>What is conditional probability? </h3>
The conditional probability is the happening of an event, when the probability of occurring of other event is given.
The probability of event A, given that the event B is occurred.
Independent events are those events whose occurrences do not depend on the other events.
The two-way table shows the distribution of book style to genre is given as,
The first column has entries paperback, hardcover, total.
The second column is labeled Fiction with entries 20, 10, 30.
The third column is labeled nonfiction with entries 60, 30, 90.
The fourth column is labeled total with entries 80, 40, 120.
Miguel claims that given that the book is paperback (PB) does not affect the outcome that the book is nonfiction (NF).
Suppose that two events are denoted by A and B. They are said to be an independent event if and only if:
Put the values as,
As both the values are equal. Thus, the claim of Miguel is correct because the two events are independent because P(NF|PB) = P(NF).

First step is to simplify the equation into a form that we are familiar with graphing, in this case the simplest way i believe is to factorise the denominator. There are many methods of factorising quadratics but in this case my preferred method would be as follows:
x^2-3x-10, because it is a quadratic equation we know it can be factorised into the form (x+a)(x+b), we know that -10 is the product of a and b, therefore a and b can only be +/-1 and -/+10, or +/-5 and -/+2, the next step is to see which of these factors sum to equal -3, in this case it will be +2 and -5, therefore x^2-3x-10 can be factorised into (x+2)(x-5).
We have now simplified the function into f(x)= (x+2)/(x+2)(x-5), we can still simplify the function further though:
(x+2)/(x+2)(x-5), the numerator and denominator have a common factor therefore we can divide the numerator and the denominator by that factor, ((x+2)/(x+2))/((x+2)(x-5)/(x+2))= 1/(x-5)
The function is now in it's simplest form, so we will now graph it. As a side note you can't perfectly "graph" any function by hand so instead we will sketch the function, to sketch a function you need to know the general shape of the function and any x/y intercepts or asymptotes.
Functions of the form a/(bx+c) are reciprocal functions, you need to be able to remember what reciprocal function looks like to be a able to sketch them by hand, they look something like this https://www.desmos.com/calculator/df2wiewhsz. To work out the x-intercept we will assign f(x) as 0, 0=1/(x-5), multiply both sides by (x-5), (x-5)0=1, 0=1, 0 doesn't equal 1 therefore there is no x-intercept but instead there is an asymptote at y=0. To work out the y-intercept we will assign x as 0, f(x)=1/(x-5), f(x)=1/-5, therefore the only y-intercept is at coordinates (0.-0.2). All reciprocal functions have 2 asymptotes, we have already found one of them, by making f(x)=0, to find the other asymptote we will make 1/(x-5)=∞, 1/0=∞, therefore x-5 has to equal 0, therefore the second asymptote will be x=5.
after putting all of this together the graph should look something like this https://www.desmos.com/calculator/bibeeu7xtv
