To determine the standard deviation of the number of people who suffer from insomnia, you need to use the following formula:
= sqr of npq

= √10,200 people in the community x 0.6 people who suffer from insomnia x 0.91 = ?
= √10,200 x 0.6 x 0.91 = <span>√55.143 = 7.43 

= 7.43</span>

-Dominant- [34]

Answer:

$7,816.9943

Explanation:

Using the high-low method;variable cost per unit=[Total cost at highest level-Total cost at lowest level]/(Highest level-Lowest level)

= $16,700 - $15,850 / 951 - 860

= $850 / 91

= $9.340659340659341

= $9.3407

Hence, total fixed cost = $16,700 - ($9.3407*951) = $16,700 - $8,883.0057 = $7,816.9943

Draw an indifference curve that shows the diminishing marginal rate of substitution. Label it IC. Draw a point on the indifferen
Hunter-Best [27]

Answer & Explanation :

Indifference Curve is a graph showing product combinations, that give consumer the same level of satisfaction.

It is a downward sloping curve, as remaining at same level of satisfaction - if consumption of one good increase, consumption of other good decrease & vice versa.So, the two goods are inversely related and the curve downward sloping

The curve is also concave i.e inwards bowing towards origin. This is because of increasing Marginal Rate of Substitution. MRS is ratio of good sacrifised to gain an additional unit of other good, staying at same satisfaction level & same indifference curve. MRS is slope of IC ; it is decreasing because - as consumer gains more & more of a good, he/ she is willing to sacrifise lesser & lesser amount of the sacrifised good each successive time.

  • A downward sloping concave inward bowing towards origin IC shows diminishing MRS
  • Any point 'A' on PPC shows product combination that yields same level of satisfaction to consumer as all other points on PPC
  • Line of slope ΔY/ΔX reflects good sacrifised, good gained ratio i.e MRS (At point A).
