Legend has it that the great mathematician carl friedrich gauss ​(1777dash–​1855) at a very young age was told by his teacher to

find the sum of the first 100 counting numbers. while his classmates toiled at the​ problem, carl simply wrote down a single number and handed the correct answer in to his teacher. the young carl explained that he observed that there were 50 pairs of numbers that each added up to 101. so the sum of all the numbers must be 50 times •101equals=5050. modify the procedure of gauss to find the sum. 1plus+2plus+3plus+...plus+320

Answer: Sum is  51360

Step-by-step explanation: I have heard same legend and it is also told in hih school math books.

There are 160 pairs numbers which sum is 321, also (320 +1) + (319+2) + ... + (160 + 161).    So sum is  160·321

A scatter plot is shown:
MatroZZZ [7]

Answer:

The correct option is 2.

Step-by-step explanation:

From the given graph it is noticed that the data points are located at (0,0), (1,0.25), (2,1), (3,2), (4,3), (5,4), (5.5,5), (6,6), (6.4,7), (6.7,7.8) and (7,9).

The rate of change from first two data points is

m_1=\frac{y_2-y_1}{x_2-x_1}=\frac{0.25-0}{1-0}=0.25

The rate of change from next two data points is

m_2=\frac{2-1}{3-2}=1

m_1\neq m_2

The rate of change it not constant, therefore the given data points are non linear.

The value of y increases as the value of x-increases. It means there is a positive relation between x and y.

Therefore the graph represent a Nonlinear positive association between x and y. Option 2 is correct.

Victor has saved $89.25 for the bicycle that he wants. The bicycle costs $129.85. Victor
fenix001 [56]

Answer: No, the equation is not correct

Step-by-step explanation:

Victor has saved $89.25 for a bicycle that costs $129.85. To get the remaining amount that is needed to complete the bicycle, we subtract the amount saved by Victor from the total amount. This will be:

= $129.85 - $89.25

= $40.6

The amount remaining is $40.6

The equation written by Victor is

= $89.25 + $129.85

= $219.1

The equation written by Victor is not correct. The correct equation is:

= $129.85 - $89.25 = $40.6
