Answer:
The length is 81 feet.
Step-by-step explanation:
If you plot the equations for both length and width on a graph, making them both equal to y of course, you find that they cross each other in two places. The places they cross are (81, 11) and (70, 0). It is impossible for the answer to have the width as 0 feet, so the answer is 81 feet.
Answer:
Systematic sampling
Step-by-step explanation:
An EPA contractor needing to test the concentration of a substance in ten samples out seventy samples provided form a single source at regular time intervals.
For the contractor to effectively carry out the testing he has to employ a Non-probability system of sampling which is called Systematic sampling, because in systematic sampling we can assume the population size (x ) which in this case is 70 and the sample size( n ) to be 10
He will have to select ; ( x / n )^th of the sampling frame for best results
Answer:
x=90
Step-by-step explanation:
First, it would help to make it so that the x's are not next to fractions. To do this, you can multiply all terms in the equation by 45. 45 is the closest common factor of 9 and 5, the denominators of the fractions. The answer would be;
20x+9x=2610
Then solve.
29x=2610
x=90
We are given with the expressions A as 2/3x + 3/5y = 12 and B as 5/2y - 3x = 6. To eliminate y, we should multiply each function with a number that when the two functions are added, y cancels out. In this case, we multiply A by 5/3 and B by -2/5. Hence the answer is D. <span>D. 5/3A - 2/5B</span>
Answer:
b. a firm whose product has an elasticity of 0.31
Step-by-step explanation:
A type of product that has elasticity less than 1 is considered as 'inelsatic goods. Inelastic goods would not have a decrease in demand even if they are increasing the price of their product.
This means that when the producer of this product increase the price, their profit will either stay stagnant or increase.
In most cases, products that are very crucial to fulfill our basic needs or day to day activity have this type of elasticity.
Example : Water and Gasoline,
