Yes.
change in y change in dep. var.
Remember the slope formula? m = ----------------- = -------------------------------
change in x change in indep. var

Remember that y is usually chosen to represent the dependent variable and x to represent the independent one?

Answer: New Mean = $40,920

New Median = $38,500

Step-by-step explanation:

5 employee's salaries are as follows in order from least to greatest:

$32,000 - unknown - $38,500 - unknown - unknown

The median (middle number) is: $38,500

The mean (average) of the 5 salaries is: $40,300

If $3,100 is added to the $32,000 salary, then the mean(average) is increased by $\dfrac{\$3100}{5\ salaries}=\$620$ .

Old Mean + increase = New Mean

$40,300 + $ 620 = $40,920

The median (middle number) does not change. It is still $38,500

I'm doing Pre-algebra and I don't know how would I figure out the 13th term of the pattern; 100, 91, 82, 73.... without writing

Over [174]

The way we would answer the question would be to express it as

100-9(n-1) with n being the nth term of the pattern.

Why is this? We know we subtract 9 each time and START from 100.
Remember though that 100 is the first term in the sequence. So, we would have (n-1)*9 to subtract 0 from our 1st term and 9 from our second term.

Also, we have 9*(n-1) because we are just subtracting multiples of 9. It is always going to subtract by 9.

If you needed the answer here it is...

The answer to the problem would be
100-9(13-1)
= 100-9(12)
= 100-108
= -8

A pair of fair dice is cast. What is the probability that the sum of the numbers falling uppermost is less than 4, if it is know

mestny [16]

The ways to make a 7 with 2 die is:
(1) 6 and 1
(2) 1 and 6
(3) 2 and 5
(4) 5 and 2
(5) 3 and 4
(6) 4 and 3
There are 6 ways to make a 7 with the 2 die,
but there is only 1 way to make 7 if the 1st
die comes up 6.
The probability of getting
(1) 6 and 1 is 1/6
