The mean salary for Linda's employees is in thousands, is: 34,800.

<h3>What is the Mean of a Data Set?</h3>
  • Mean of a data set is the average of the data set.
  • To calculated the mean of a data set, use the formula: Mean = (∑fx)/∑f).

Thus:

∑fx = 974

∑f = 28

Therefore:

Mean = 974/28

Mean = 34.8

In thousands, the mean salary for Linda's employees is 34,800.

The supply curve for steel is 90x−y=−50. The demand curve is 10x+y=200. x is quantity in thousands of metric tons y is price in
ivolga24 [154]

Answer:

The intersection point of the two curves is (x,y) = \left(\frac{3}{2}\,kton.m, 185\,USD \right).

Step-by-step explanation:

From statement we get the following equations:

Supply curve

90\cdot x - y = -50 (1)

Demand curve

10\cdot x + y = 200 (2)

Where:

x - Quantity, measured in thousands of metric tons.

y - Price, measured in US dollars per metric tons.

If we add both equations, then we find that quantity is:

(90\cdot x -y )+(10\cdot x +y) = -50+200

100\cdot x = 150

x = \frac{3}{2}\,kton.m

Then, we finally find the price by substituting on (2):

y = 200-10\cdot \left(\frac{3}{2} \right)

y = 200-15

y = 185\,USD

The intersection point of the two curves is (x,y) = \left(\frac{3}{2}\,kton.m, 185\,USD \right).
