The slope and intercept form of the equation of a straight line graph is y = m \cdot x + c

False: <em>Graphs of two lines either </em><em>intersect </em><em>in one point or do not </em><em>intersect</em><em>. Thus graphs of </em><em>two lines</em><em> may have one point or no points in common</em>

False: <em>Graphs of two </em><em>lines </em><em>either intersect in one point or overlap. Thus graphs of two lines may have one point or an </em><em>infinite </em><em>number of </em><em>points </em><em>in common</em>

<em />

Reason:

First statement;

<em>Graphs of two lines either intersect in one point or do not intersect. Thus graphs of two lines may have one point or no points in common</em>

The above statement is false; graphs of two lines may have an infinite number of points in common when they have the same slope and y-intercept

Second statement;

<em>Graphs of two lines either intersect in one point or overlap. Thus graphs of two lines may have one point or an </em><em>infinite </em><em>number of points in common </em>

The above statement is false; graphs of two lines that have the same slope but different y-intercept never intersect

A random sample of n people selected from a large population will be asked whether they have read a novel in the past year. Let
kozerog [31]

Answer:

b. A binomial variable with 25 independent trials

Step-by-step explanation:

The conducted experiment is binomial experiment because outcome can be divided into success or failure. The success would be the people who read novel in the past year and also responses are independent of each other. We have to find the number of trials n in the given problem.

we are given that variance of R=6 and p=probability of success=0.4.

We know that variance of binomial distribution is

Variance=npq

where q=1-p=1-0.4=0.6.

By putting the values in variance formula, we can get the value of n.

6=n*0.4*0.6

6=0.24*n

n=6/0.24

n=25

Hence, random variable R is a binomial variable with 25 independent trials.

factor completely 4x5 − 20x4 − 36x3. 4(x5 − 5x4 − 9x3) x3(4x2 − 20x − 36) x2 − 5x − 9 4x3(x2 − 5x − 9)
Mila [183]

Consider the polynomial 4x^5 - 20x^4 - 36x^3. It has three terms and their greatest common factor is 4x^3.

Since

4x^5=4x^3\cdot x^2,\\20x^4=4x^3\cdot 5x,\\36x^3=4x^3\cdot 9,

then

4x^5 - 20x^4 - 36x^3=4x^3(x^2-5x-9) (you write in brackets the same sign as the corresponding term has).

Answer: correct choice is D.
