The sign of f on the interval -5/3 is negative

<h3>How to determine the sign?</h3>

The function is given as:

f(x)=(2x−1)(3x+5)(x+1)

The zeros of the function are

x= -5/3, x= -1 and x= 1/2

Next, we plot the graph of the function

At x = -5/3, the function approaches negative infinity

This means that the sign of f on the interval -5/3 is negative

Part A: Group A is a cluster of points. Group B Is not even a group this point is an outlier. A possible reason Point B is involved is because there could be a student that although played a lot of video games, he studied too and got a good score.  

Part B: The association is a negative linear association. Also as students play more video games the test scores tend to go down.

Mrs. Eraca gives this cute dog 4.5 treats that cost $3.59 per treat. How much total money does she spend on this mooching pooch?
kozerog [31]

Answer:

$16.16

Step-by-step explanation:

multiply the amount of treats by the cost of each treat.

4.5 × 3.59 = 16.155.

rounded up gives you $16.16

1 = 3.59

2= 7.18

3= 10.77

4= 14.36

half or .5 of 3.59 is 1.795

14.36 + 1.795 = 16.155 = rounded up $16.16
