Gloria collected data from a random sample of 1200 students in her school district asking whether or not they read more than one

Vitek1552 [10]

Answer: Sample is biased

Step-by-step explanation:

In her experiment, Gloria assumes that the reading habits of the students in her school district are exactly the same to that of students in all state schools. This assumption is unlikely to be true and, therefore, this statistic is misleading because the sample used is biased.

From her data, all Gloria can do is report the percentage of students that read more than one book per month in her school district

Find all x-intercepts and y-intercepts of the graph of the function . f(x) = - x ^ 3 + x ^ 2 + 12x If there is more than one ans

ololo11 [35]

Answer:

The y-intercept is (0,0)

The x-intercepts are (-3,0), (0,0), and (4,0)

Step-by-step explanation:

So we have the function:

$f(x)=-x^3+x^2+12x$

And we want to solve for the x- and y-intercepts.

To solve for the y-intercept, recall that the y-intercept is when the graph touches the y-axis. At that point, the x values is 0. Thus, to find the x-intercept, substitute 0 for x:

$f(x)=-(0)^3+(0)^2+12(0)$

Simplify:

$f(x)=0$

So, the y-intercept is (0,0)

To solve for the x-intercept(s), set the function equal to 0 and solve for x:

$0=-x^3+x^2+12x$

First, factor out a negative x:

$0=-x(x^2-x-12)$

Factor within the parentheses:

$0=-x(x-4)(x+3)$

Zero Product Property:

$-x=0\text{ or } x-4=0\text{ or } x+3=0$

Divide by -1 on the first one. Add 4 on the second one. And subtract 3 on the right:

$x=0\text{ or } x=4\text{ or } x=-3$

So, our x-intercepts are:

$(-3,0), (0,0), (4,0)$

And we're done :)

A baseball team played 160 regular season games. The ratio of the number of games they won to the number of games they lost was

NeX [460]

Answer: They won 60 games and lost 100 games

Explanation: To find this, first, we need to keep in mind that for every 8 games they played, they won 3, and lost 5. With this, we need to do 160/8 and we will get 20. Finally, to find # of games won, we will do 3(20) which is 60, and to find # of games lost, we will do 5(20) which is 100. Hope this helped!
