Using the inequality, the school will need $ 146 in order for each student to have a hamburger
If this is the inequality:
124 + x ≥ 270
1) deduct 124 from both sides
124 + x - 124 ≥ 270 - 124
x ≥ 146
x can be 146 and below because the inequality sign states x is less than or equal to 146.
The school needs an additional maximum amount of 146 in order for each student to have a hamburger.
<h3>
What is inequality?</h3>
- An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way.
- The majority of the time, size comparisons between two numbers on the number line are made. Different types of inequalities are represented by a variety of notations, including:
- The symbol a < b indicates that a is smaller than b.
- When a > b is used, it indicates that a is bigger than b.
- A is not equivalent to b in any scenario. These relationships are referred to be stringent inequalities since either an or b is strictly bigger or less than the other. Equivalence is not considered.

Answer:
the covariance between the revenue and cost is 1,513. What is the variance of the profit (X-Y) of the company is 303468
Step-by-step explanation:
Given that;
E(x) = 6263
SD(x) = 440
F(y) = 4872
SD(y) = 336
COVI (x, y) = 1513
Variance x = [ SD(x) ]²
Variance x = [440]² = 193600
Variance y = [ SD(y) ]²
Variance y = [336]² = 112896
Now to get variance of the profit (X-Y) of the company we say;
variance ( x-y ) = variance x + variance y - 2covi(x.y)
we substitute
variance ( x-y ) = 193600 + 112896 - ( 2 × 1513 )
variance ( x-y ) = 306496 - 3026
variance ( x-y ) = 303468
therefore the covariance between the revenue and cost is 1,513. What is the variance of the profit (X-Y) of the company is 303468
-8x - 8.
16x - 24 x = -8x
-12 + 4 = 8
Answer:
The exact cost of producing the 21st food processor is $38.52.
The marginal cost to approximate the cost of producing the 21st food processor is $38.24
Step-by-step explanation:
Consider the provided function.

(A) Find the exact cost of producing the 21st food processor
The exact cost producing 21st food processor is C(21)-C(20)
Substitute x=21 in above function.



Substitute x=20 in above function.



The exact cost producing is:

Hence, the exact cost of producing the 21st food processor is $38.52.
Part (B) Use the marginal cost to approximate the cost of producing the 21st food processor,
To find the marginal cost first differentiate the function with respect to x.


Now substitute x=21 in above function.


The marginal cost to approximate the cost of producing the 21st food processor is $38.24
Part A: Yes there is. As the number of workers increases, so does the production.
Part B: y = 5x + 2
Part C: The slope indicates that for every person there is 5 units being produced, and the y-intercept indicates that 2 units are being made every day, regardless of if there are no workers ( this, however is unrealistic but it is how the data is )
