The 2003 Zagat Restaurant Survey provides food, decor, and service ratings for some of the top restaurants across the United Sta

earnstyle [38]

Answer:

The probability that none of the meals will exceed the cost covered by your company is 0.2637.

Step-by-step explanation:

A hyper-geometric distribution is used to define the probability distribution of k success in n samples drawn from a population of size N which include K success. Every draw is either a success of failure.

The random variable X = number of meals that will exceed the cost covered by the company.

The random variable X follows a hyper-geometric distribution.

The information provided is:

N = 15

K = 3

n = 5

k = 0

The probability mass function of a hyper-geometric distribution is:

$P(X=k)=\frac{{K\choose k}{N-K\choose n-k}}{{N\choose n}}$

Compute the probability that none of the meals will exceed the cost covered by your company as follows:

$P(X=0)=\frac{{3\choose 0}{15-3\choose 5-0}}{{15\choose 5}}=\frac{1\times 792}{3003}=0.2637$

Thus, the probability that none of the meals will exceed the cost covered by your company is 0.2637.

HELP PLEASE 20 POINTS 1) What is the equation of the line in slope-intercept form?

Nezavi [6.7K]

Answer:

y = (-5/4)x + 5

Step-by-step explanation:

Slope-intercept form is y = mx + b

m is the slope and b is the y-intercept

To find m, we can use the plotted points on the graph

(0,5)(4,0)

Now, do delta y/ delta x

(0-5)/(4-0)

slope = -5/4

Now, the y-intercept is the point where the graph crosses the y-axis

This point is where x is 0. Here, when x is 0, y is 5.

Therefore, the y-intercept is 5

Finally, replace what you've found into the equation

y = (-5/4)x + 5

You decide to put the Gamer table on sale for 20% off. You normally charge $210 for this table. What is the amount of the discou

kvasek [131]

First, you would multiply $210 by 20%
This is done by converting 20% to a decimal, .2

So, 210 • .2 = 42

Then to find the sale price, you would subtract that 42 that you just got from 210,

and you get $168 as the final sale price.
