It was reported that approximately 15.5 million telephone votes were cast. Each vote was for
kati45 [8]

Answer:

Alejandro received 6.51 million of votes

Laine received 58% of votes

Step-by-step explanation:

If the ratio of "Laine votes" to "Alejandro votes” was 29:21, then the number of "Laine votes" was 29x and the number of "Alejandro votes” was 21x. In total, 15.5 million votes were cast. So

29x + 21x = 15.5 million

50x = 15.5 million

x = 0.31 million

Then

the number of "Laine votes" =29\cdot 0.31=8.99 million

number of "Alejandro votes” =21\cdot 0.31=6.51 million

Laine received

\dfrac{8.99}{15.5}\cdot 100\%=58\%

John assignments in value of his car overtime the equation for the line of best fit is approximate as Y represents 2.9 X +17.7 w
ycow [4]

Answer:

For the given equation of the line of best fit, the values that complete the table are as follows

An equation for a line of best fit follows the same guidelines as a linear function where 'y' represents the total (value), 'x' represents time (years), -2.9 is the rate, and 17.7 is the starting value.  The table indicates that for any year, there is a given value, but what we are solving for is the predicted value.  The residual is the different between the given and predicted values.  So, for 'a', we need to solve for the 'y' in our equation by replacing 'x' with '1', multiplying by -2.9 and adding 17.7.  This gives us 14.8.  For 'b', we simply need to subtract the given and predicted values to get a residual of 0.1.  For 'c', we again solve for 'y' by replacing 'x' with '3' in our given equation to get 9. And, for 'd' we subtract the given value of 5 and the predicted value of 6.1 to get 1.1.

answer-

a = 14.8

b = 0.1

c = 9

d = -1.1
