It’s not because if you rotate it a bit you will see that the straight vertical side and straight horizontal side of the triangle form an acute angle, not a 90 degree angle

Answer:

  • No

Step-by-step explanation:

You may find the slopes of the segments EG and FG, the shorter sides of the triangle EFG.

Perpendicular lines have negative-reciprocal slopes.

  • m(EG) = (-3 - 7)/(-6 - (-2)) = -10/-4 = 5/2
  • m(FG) = (-3 - (-8))/(-6 - 7) = 5/-13 = -5/13

<u>The product of the slopes should be -1:</u>

  • 5/2*(-5/13) = - 25/26 ≠ -1

So the answer is No

. Choose the correct means and standard deviations for the Sincere and Insincere conditions. Make sure to round to two decimal p
tensa zangetsu [6.8K]

Answer:

C. The rudely disagrees condition has a mean of 4.16 and a standard deviation of 0.85 while the politely disagrees condition has a mean of 3.82 and standard deviation of 0.97

Step-by-step explanation:

The given data is  

                                          x`             Std. Dev      

R. disagrees                  4.16       0.854        

P. disagrees                 3.82       0.967        

From this data we see that the R. disagrees has a mean of 4.16 and standard deviation of 0.854

while

the P. disagrees has a mean of 3.82 and standard deviation of 0.967.

Same figures are given only in option C because

Rounding 0.854 gives 0.85

Rounding 0.967 gives 0.97

So only option C is the best choice.

C. The R. Disagrees condition has a mean of 4.16 and a standard deviation of 0.85 while the P. Disagrees condition has a mean of 3.82 and standard deviation of 0.97

Which of the statements are true regarding dot plots bar graphs and historgrams
andrey2020 [161]

the only statement that is true is the one in option D.

"Bar graphs are used to represent data that is discrete".

<h3>Which of the statements are true regarding dot plots, bar graphs, and histograms?</h3>

Dot plots,  bar graphs, and histograms are used to repersent graphically data sets.

Thus, what these graphs do represent are populations in a data set with a given property.

Remember that data is usually discrete, so we usually use dot plots and bar graphs to represent discrete data.

Histograms show distributions of numerical data (it can be used for continuous or discrete data).

With all that in mind, we conclude that the only statement that is true is the one in option D.

"Bar graphs are used to represent data that is discrete".
