The system of equations shown below is graphed on a coordinate grid:

4y + x = 4
2y − x = 8

which statement is true about the coordinates of the point that is the solution to the system of equations?

it is (2, 5) and lies on both lines.
it is (−4, 2) and lies on both lines.
it is (2, 5) and does not lie on either line.
it is (−4, 2) and does not lie on either line.

The mean of a set of data is -3.82 and its standard deviation is 2.31. find the z score for a value of 3.99.

Will mark brainliest with 20 points! the table shows how far object 1 traveled as a function of time. *time (seconds) - 2 4 6 8 *distance traveled (feet) - 18 36 54 72 the equation shows how far object 2 traveled in feet as a function of time in minutes. *f(x) = 10x which object traveled at a faster speed? justify your response.

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
