Is the following Inductive Generalization strong or weak? Apply and explain the three checks: 1. Is the appropriate group sample

d? 2. Is the sample truly random? 3. Is the sample adequate in number? Then give your verdict: strong or weak.
Oxytocin seems to make people more inclined to trust strangers with their cash. In a game in which 58 volunteers could invest money with anonymous trustees, economist Ernst Fehr of the University of Zurich and his colleagues dosed half the subjects with a whiff of oxytocin while the others received an inert placebo nose spray (but were told it was a real drug). After investors who sniffed the actual oxytocin were twice as likely to invest all their funds.

Answer:

For the reasons mentioned in the explanation section, it is indeed a weak generalization:  

Step-by-step explanation:

  • No, there is not enough data provided on certain subjects' age, socioeconomic status, etc. that may have influenced the investing decision.
  • No, the survey isn't random, the study is irregular because each has a fair probability of expressing their true beliefs, here in this query it's written they've been told individuals are given actual medication, which may have contributed to the Hawthorne studies giving incorrect outcomes.
  • No, the amount isn't sufficient mostly on the premise of 28 subject areas with be provided oxytocin, and therefore only one test being performed should we not be able to determine the results to implement for certain persons including billions of populace, it would be a hurried generalization.

A freight elevator has a weight limit of 15,000 pounds. Workers have loaded items weighing 2.6 tons onto the elevator. How many
k0ka [10]

Given :

A freight elevator has a weight limit of 15,000 pounds.

Workers have loaded items weighing 2.6 tons onto the elevator.

To Find :

How many more pounds of freight can they load before reaching the weight limit.

Solution :

We know, 1 ton = 2000 pounds.

So, 2.6 ton = 2.6 × 2000 = 5200 pounds.

Now, number of pounds of freight can be loaded before reaching the weight limit is :

N = 15000 - 5200 pounds

N = 9800 pounds

If C(x) is the cost of producing x units of a commodity, then the average cost per unit is c(x) = C(x)/x. Consider the cost func
nadya68 [22]

Answer:

a) C(1,000)=288,491.11 $

b) c(1,000)=288.49 $/u

c) dC/dx(1,000)=349.74 $/u

d) x=100 u

e) c=220 $/u

Step-by-step explanation:

(a) Find the total cost at a production level of 1000 units.

C(x) = 2,000 + 160x + 4x^{3/2}\\\\C(1,000)=2,000 + 160(1,000) + 4(1,000)^{3/2}\\\\C(1,000)=2,000+160,000+126,491.11= 288,491.11

(b) Find the average cost at a production level of 1000 units.

c(x)=C(x)/x\\\\c(1,000)=C(1,000)/1,000=288,491.11/1,000=288.49

(c) Find the marginal cost at a production level of 1000 units.

\frac{dC}{dx} =0+160+4*(3/2)x^{3/2-1}=160+6x^{1/2}\\\\dC/dx|_{1,000}=160+6*(1,000)^{1/2}=160+189.74=349.74

(d) Find the production level that will minimize the average cost.

c=2,000x^{-1}+160+4x^{1/2}\\\\dc/dx=2,000(-1)x^{-2}+0+4(1/2)x^{-1/2}=0\\\\-2,000x^{-2}+2x^{-1/2}=0\\\\2x^{-1/2}=2,000x^{-2}\\\\x^{-1/2+2}=1,000\\\\x^{3/2}=1,000\\\\x=1,000^{2/3}=100

(e) What is the minimum average cost?

c(x) = 2,000/x + 160 + 4x^{1/2}\\\\C(100)=2,000/100 + 160 + 4(100)^{1/2}=20+160+40=220

Find the value of x in the triangle (not drawn to scale.)
AlekseyPX

Your answer would be 29

Why?

Because that is a right angle. They always have to be 90° so 90-61=29
