If there is a 30% chance a student will fail a class at Fresno State, find the probability that of four randomly chosen students.All fail a class.

Answers

Answer 1

Answer:

Answer:

81%

Step-by-step explanation:

If there is a 30 percent chance a student will fail a class at Fresno State, we can simply multiply the percentage by the probabilities of all students failing. Every option available:

P(All four fail) = 1 student fails * 2 students fail * 3 students fail * 4 students fail

P(All four fail) = 0.3 * 0.3 * 0.3 * 0.3

P(All four fail) = 0.0081

0.0081 = 81%

Answers

Answer:

Options (C) and (E)

Step-by-step explanation:

Given polynomial is,

6x⁴+ 4x³- 7x² + 5x + 8

So all the polynomials which are (look alike) similar in terms of degree and number of terms to the given expression will be equivalent.

Option (A).

$16x^(10)$

It's a monomial. So not the answer.

Option (B).

6x⁵ + 4x⁴ - 7x³ + 5x² + 8

This polynomial is a 5th degree polynomial, will not be equivalent to the given polynomial expression with 4 degree.

Option (C).

6x⁴ + 4x³ - 7x² + 5x + 8

All the terms and signs between the terms of this expression are similar to the given polynomial expression,

Expression will be equivalent to the given polynomial expression.

Option (D)

8 + 5x + 7x² - 4x³ + 6x⁴

= 6x⁴- 4x³ + 7x² + 5x + 8

Both are similar in number of terms and degree but signs between the terms are different.

Therefore, both the expressions are will not be equivalent.

Option (E).

8 + 5x - 7x² + 4x³ + 6x⁴

= 6x⁴ + 4x³ - 7x² + 5x + 8

Since, both the polynomials are similar so they are equivalent.

The difference between the highest and lowest single game point totals for the MIDDLE HALF of the data is ______ points less for Joe's data than Sam's data. Therefore, the MIDDLE HALF of Joe's single game point totals are less varied than Sam's.

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the required data to answer the question are missing.

However, the interpretation of the question is to determine the interquartile range (IQR) of a certain dataset.

Then get the difference between the calculated IQR & Joe's data and also the difference between the calculated IQR & Sam's data

Then, make comparison

To do this, I will use the following assumed datasets.

$Data: 62, 63, 64, 64, 70, 72, 76, 77, 81, 81$

IQR is calculated as:

$IQR = Q_3 - Q_1$

$Q_3$ is $the\ median$ of the upper half

$Q_1$ is $the\ median$ of the lower half

For Joe, we have:

$Lower\ half: 62, 63, 64, 64, 70$

$Upper\ half: 72, 76, 77, 81, 81$

The median is then calculated as:

$M = (N + 1)/(2)$

For, the lower half:

$Q_1 = (5 + 1)/(2) = (6)/(2) = 3rd$

So:

$Q_1 = 64$

For the upper half:

$Q_3 = (5 + 1)/(2) = (6)/(2) = 3rd$

So:

$Q_3 = 77$

When the same process is applied to Sam's data,

$Q_1 = 52$

$Q_3 = 58$

$IQR = Q_3 - Q_1$

$IQR = 77 - 64$

$IQR = 13$

Assume that:

$Joe = 60$

$Sam = 65$

$Joe - IQR = 60 - 13 = 47$

$Sam- IQR = 65- 13 = 52$

Hence, the IQR is 47 points less for Joe's data than Sam's

The revenue, in dollars, of a company that produces jeans can be modeled by 2x2 + 17x – 175. The cost, in dollars, of producing the jeans can be modeled by 2x2 – 3x – 125. The number of pairs of jeans that have been sold is represented by x. The profit is the difference between the revenue and the cost, 20x – 50.If 75 pairs are sold, what's the company's profit?

a)$500
b)$1,450
c)$1,500
d) $2,250

Hello,

P(x)=20x-50
==>P(75)=20*75-50=1450
Answer B

The correct answer is the second option!

B) $1,450

The Mathalot Company makes and sells textbooks. They have one linear function that represents the cost of producing textbooks and another linear function that models how much income they get from those textbooks. Describe the key features that would determine if these linear functions ever intercepted.

Answers

The question is asking to explain or described the key features that would determine if the linear functions is ever intercepted base on the said equation and the function, I would say that the answer would be If two linear equations have different slopes, and are in the same plane, they WILL intersect at ONE point (they will have a unique solution).
