Answer:

0.8 i think

Step-by-step explanation:

Step 1: So i subtracted 8 from the postive 8 and 7.2

Step 2: Then I got 4x= -0.8 + 5x

Step 3: Now that were left with thart i subtracted 5 from the postive 5x and from the postive 4x

Step 4: I have -1 = -0.8

Step 5: subtract the -1 from the -1 and the -0.8 which will equal... a postive 0.8!

The thickness of a flange on an aircraft component is uniformly distributed between 0.95 and 1.05 millimeters. (a) Determine the
maxonik [38]

Answer:

a) 0.5 = 50% of flanges exceed 1 millimeter.

b) A thickness of 0.96 millimeters is exceeded by 90% of the flanges

Step-by-step explanation:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distributon has two bounds, a and b, and the probability of finding a value higher than x is given by:

P(X > x) = \frac{b - x}{b - a}

The thickness of a flange on an aircraft component is uniformly distributed between 0.95 and 1.05 millimeters.

This means that a = 0.95, b = 1.05

(a) Determine the proportion of flanges that exceeds 1.00 millimeters.

P(X > 1) = \frac{1.05 - 1}{1.05 - 0.95} = \frac{0.05}{0.1} = 0.5

0.5 = 50% of flanges exceed 1 millimeter.

(b) What thickness is exceeded by 90% of the flanges?

This is x for which:

P(X > x) = 0.9

So

\frac{1.05 - x}{1.05 - 0.95} = 0.9

1.05 - x = 0.9*0.1

x = 1.05 - 0.9*0.1

x = 0.96

A thickness of 0.96 millimeters is exceeded by 90% of the flanges

Mary and Cathy are roommates. Mary assigns a $30 value to smoking cigarettes. Cathy values smoke-free air at $15. Which of the f
Shtirlitz [24]

Answer:

b. Mary pays Cathy $16 so that Mary can smoke.

Step-by-step explanation:

Coase's theorem suggests that in a situation where a bargaining situation, where there is efficient pareto allocation, economic agents can negotiate and come to a compensation agreement on the loss of welfare.

Pareto Optimal is a state where resources are allocated as efficiently as possible. Any reallocation of resources to improve one individual's situation will necessarily worsen another individual's condition. That is the case in point. Mary has a $ 30 utility for smoking, while Cathy has a $ 15 utility for fresh air. If both are in the same environment, Mary's activity will damage Chaty's usefulness. A deal would be if Mary offered Cathy a reward beyond her usefulness, and was then allowed to smoke. Since Cathy's utility is $ 15, if Mary offers $ 16, Cathy's utility will be greater with Mary smoking than before.
