Answer:
76.09 pounds
Step-by-step explanation:
From the information given:
At a slower of 4 gal/min, the solution gets pumped out;
So,
The differential of the equation is:
For the linear differential equation, the integrating factor is determined as:
Multiplying with the above integration factor;
By using the given condition:
A(0) = 40
40 = 50 + c (50)⁻²
10 = c(50)⁻²
OR
c = -10 × 2500
c = -25000
A = (50 + t) - 25000(50 + t)⁻²
The number of pounds of salt in the tank after 30 min is:
A(30) = (50+30) - 25000(50 + 30)⁻²
Thus, the number of pounds of salt in the tank after 30 min is 76.09 pounds.

Answer:
The data is symmetrical
Step-by-step explanation:
In order for the data to be symmetrical, the mean and median have to be the same number, if they're not, then the data is skewed one way or another.
Hope this helps and have a good day/night!
(a) |-9| + 6 = 9 + 6 = 15
(b) |-9 + 6| = |-3| = 3
