Option a. The total force that is calculated is given as 24 n/s

<h3>How to solve for the magnitude</h3>

300 g = 0.3kg

Force = change in momentum / time

We have to find the mass x velocity

0.3 x 40 = 12kg m / s

This rubber ball is said to strike and also rebound immediately. We can take the time as 1 second.

Force 1 x 12

= 12 N

The force that is exerted after the rebounding has occurred is also 12 N following Newton's 3rd law.

The total force that is exerted would be calculated as 12N + 12N = 24 N/S

Hey there! :)

Your answer is mean
_____________________________________________________________

Mean is the average value of the data set.
Mode is the number that appears the most
Range is the difference between the greatest value and the lowest value in a data set.

Finding the mode is pretty useless because you can't do much with the score that you got the most.

Range isn't that helpful because it's the difference between your best and worst score.

Mean is best for summarizing because you have 1 number that's the average of the whole data set.
______________________________________________________________

Therefore, the answer is mean

Hope this helps :)

A local news story claims that 53 of high school males agree with the statement.
horrorfan [7]

Based on the information given regarding the sampling, the correct option is E. No, because p = 0.53 was one of the most common values in the sampling distribution.

<h3>How to solve the sample.</h3>

From the complete information, it can be deduced that on the dotplot, the center of the sampling distribution is around 0.53. This means that if we construct a confidence interval, there is a high probability that it will have a value of 0.53.

Also, for less than 53% to be true, then most of the dots should have been less than 0.53. In this case, it is centered around 0.53 and so this illustrates that a lot of values are equal to and above 0.53.

Naddik [55]

Answer:

The correct answer is option D "People needed to work faster than the weather. . . ."

Explanation:

The text refers to sugar as "a killer" in Louisiana as they did not have the hot weather as in the Caribbean to harvest.

Then, slaves had to increase their production and beat the weather because otherwise the crop would be completely ruined.

For this reason, the work of slaves in Louisiana was much more exhaustive than in the Caribbean.

SSSSS [86.1K]

The graph is not found here, but a residual plot shows that the line of best fit is appropriate for data when points are well distributed on the x-axis.

<h3>What is a residual plot?</h3>

A residual plot is a diagram showing residual values on the Y-axis and an independent variable on the X-axis.

This type of plot (residual plot) is used to see the matches between observed and fitted response values.

In conclusion, the graph is not found here, but a residual plot shows that the line of best fit is appropriate for data when points are well distributed on the x-axis.
