Answer:
-19+-25f≤-144
Step-by-step explanation:
The problem says that you descended 19 below sea level. Below makes 19 into a negative. It also says that it descends 25 feet per minute. If it says per you put a variable by that number. It also says descends which means going down so that would be a negative. The problem says Lainey does not want to go over 144 feet(144 is also negative because it is below sea level) so 144 would be greater than or equal to because she does not wan to go over that amount.
Hope this helps!
Answer:
n/3 - 18
Step-by-step explanation:
"quotient of a number and 3" is n/3, and so
"18 less than the quotient of a number and 3" as an expression is:
n/3 - 18
Our current equation is:
-5(3n + 4) = 40
To solve for this, we need to use the Distributive Property. The Distributive Property allows any number/variable outside of the parenthesis to be multiplied by all numbers/variables inside of the parenthesis.
For example, 3(2 + 3) would be:
3(2) + 3(3)
6 + 9
15.
Now that we've defined our terms and provided an example, I think we're ready to solve.
-5(3n + 4) = 40
-5(3n) + -5(4) (multiplying a positive by a negative makes a negative)
-15n -20 = 40
Add 20 to both sides to get -15n by itself.
-20 + 20 = 0
40 + 20 = 60
We now have:
-15n = 60
Divide both sides by -15 to solve for n.
-15n / -15 = n
60 / -15 = -4
N = -4.
Your answer is A.) -4.

Answer:
the average distance from the mean is:
$ 7.2
step-by-step explanation:
we are given data points as:
$7, $20 , $9 , $35 , $12 , $15 , $7 , $10 , $20 , $25 , $7 , $20 , $9 , $35 , $12 , $15 , $7 , $10 , $20 , $25
the mean of the data set is:
now we are asked to find the average distance from the mean or mad of the data.
the absolute difference of each data point from mean is calculated as follows:
|7-16|=9
|20-16|=4
|9-16|=7
|35-16|=19
|12-16|=4
|15-16|=1
|7-16|=9
|10-16|=6
|20-16|=4
|25-16|=9
|7-16|=9
|20-16|=4
|9-16|=7
|35-16|=19
|12-16|=4
|15-16|=1
|7-16|=9
|10-16|=6
|20-16|=4
|25-16|=9
the answer is: $ 7.2
