Please help 1. Find the error & explain why it is wrong:
laural had to find the inverse of the function f(x)=-x+3. What did she do wrong?

Step A: f(x)=-x+3
Write the function

Step B: y=-x+3
Replace f(x) with y

Step C: -x=y+3
Switch the x and y values

Step D: -3-x=y
Isolate y by subtracting 3 from both sides

Step E: f^-1(x)=-3-x
State the inverse by replacing y with f^-1(x)

Step___is incorrect because . Instead, you should .

2. Find the error & explain why it is wrong:
Jon had to find the inverse of the function f(x)=6x-11. What did he do wrong?

Step A: f(x)=6x-11
Write the function

Step B: y=6x-11
Replace f(x) with y

Step C: x=6y-11
Switch the x and y values

Step D: x+11=6y
Isolate y by adding 11 to both sides

Step E: x/6+11=y
Isolate y by dividing both sides by 6

Step F: f^-1(x)=x/6+11
State the inverse by replacing y with f^-1(x)

Stepis incorrect because. Instead, you should.

The probability that an adult possesses a credit card is .70. a researcher selects two adults at random. by assuming the independence, the probability that the first adult possesses a credit card and the second adult does not possess a credit card is:

(c) compare the results of parts (a) and (b). in general, how do you think the mode, median, and mean are affected when each data value in a set is multiplied by the same constant? multiplying each data value by the same constant c results in the mode, median, and mean increasing by a factor of c. multiplying each data value by the same constant c results in the mode, median, and mean remaining the same. multiplying each data value by the same constant c results in the mode, median, and mean decreasing by a factor of c. there is no distinct pattern when each data value is multiplied by the same constant. (d) suppose you have information about average heights of a random sample of airline passengers. the mode is 65 inches, the median is 72 inches, and the mean is 65 inches. to convert the data into centimeters, multiply each data value by 2.54. what are the values of the mode, median, and mean in centimeters? (enter your answers to two decimal places.) mode cm median cm mean cm in this problem, we explore the effect on the mean, median, and mode of multiplying each data value by the same number. consider the following data set 7, 7, 8, 11, 15. (a) compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = (b) multiply 3 to each of the data values. compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = --
