Answer:

The answer is B

Step-by-step explanation:

f(x) = 2x-1

f(0) = 2(0)-1

= -1

f(2) = 3

f(4) = 7

f(6) = 11

f(8) = 15

A professor graded the final exams and found that the mean score was 70 points. Which of the following can you conclude?
larisa86 [58]

Answer:  C) 50% of the students scored below 70%

<u>Step-by-step explanation:</u>

Mean is the average.  To find the mean (aka average) you add up all of the scores and divide by the number of tests.  

B) The mean can be 70 without any test scoring 70% so B is not true.

A) Since B is not true, then A is not a valid option.

D) We don't know any of the other data so don't know if it is skewed left, skewed right, or normal.  Therefore, option D is not true.

C) If the average is 70%, then half received grades above that score and half received grades below that score.  So, option C is TRUE!

14&gt;-2(2z+3)<br>please help me!!
Veseljchak [2.6K]

Answer:

14 > -2 (2z + 3)

First you need to distribute the -2 inside the parentheses.

14 > -2(2z) + -2(3)

14 > -4z - 6              -Add 6 to both sides of the equation

14 + 6 > -4z - 6 + 6

20 > -4z              -Now divide by -4 on both sides

20 / -4 > -4z / -4

-5 > z

However, when you divide by a negative number, you MUST flip the sign.

So, the answer is:

-5 < z

Hope this helps!
