Vinil7 [7]

Answer:

We can deduce that the elasticity of the labor supply is greater than 1 the labor supply is considered elastic

Step-by-step explanation:

The formula to use is the following:

Elasticity = (Change in working hours / Average working hours) / (Change in wage rate / Average wage rate)

we replace the data

Elasticity = [(7 - 3) / (7 + 3) / 2] / [(50 - 30) / (50 + 30) / 2]

Elasticity = [4 / (10/2)] / [20 / (80/2)]

Elasticity = (4/5) / (20/40)

Elasticity = 0.8 / 0.5

OUTCOME

Elasticity = 1.6

We can deduce that the elasticity of the labor supply is greater than 1 the labor supply is considered elastic

What is the product of 3 square root 7 and 17 square root 14 in simplest radical form ​
Aleks [24]

3 \sqrt{7}  \times 17 \sqrt{14}

This is the problem that we need to solve. The best way to get about it is to first:

  1. Multiply the constant numbers (3 and 17). 3×17 is 51.
  2. Next multiply the radicals.
  3. \sqrt{7}  \times   \sqrt{14}  =  \sqrt{7 \times 14}  =  \sqrt{108}
  4. Simplify the squareroot of 108 since it is 49 times 2. It would be equal to 7 squareroots of 2.
  5. Our final answer would be:
  6. 51 \times  7\sqrt{2}  = 357 \sqrt{2}
  7. 51 x 7 is 357, so the answer above is right.

The skills needed are multiplication, mulitplication of radicals, and simplifying radicals, so if you want to review anything use these as reference.

Hope you understood and have a nice day!!

in his first three rounds of golf, Jon scored 72, 78, and 73. What is the highest score he can earn in his fourth round and stil
kupik [55]
No greater means equal or less. Because the problems asks about the highest score(maximum value), we are going to solve following equation:
(72+78+73+x)/ 4 = 74
(72+78+73+x)=74*4
223+x=296
x=296-223= 73
Answer is 73.
