Natural selection suggests that creatures with mutations disadvantageous to survival will not live to reproduce, yet there are e
neonofarm [45]

Answer:

<em>No, these exceptions do not discredit natural selection.</em>

Explanation:

Natural selection tends to favour those organisms which are better adapted to live in an environment. But it does not completely remove the other organisms from the world that are less adapted to live in an environment. Usually, the number of these organisms that are not favoured by natural selection is very less as compared to the number of organisms which are favoured by natural selection. As we see, the number of albino animals is far lesser as compared to their wild-type animals.

ruslelena [56]

[Incomplete question. I found these data in other source]

<span> <span><span> <span> Labor </span> <span> 520 hour at $13 per hour </span> </span> <span> <span> solvent: </span> <span> 100 gallons at $5 per gallon </span> </span> <span> <span> machine rental </span> <span> 20 days at $50 per day </span> </span> </span></span>

<span>a. what is the labor productivity per dollar?
b. what is the multi-factor productivity?</span>

Answer:

a) You have to divide the dollars spent in labor with the number of rugs produced.

In order to calculate the dollars spent in labor, you have to multiply the number of hours worked with the price per hour.

labor expense = 520h*13$/h=$6760

labor productivity per dollar = 65rugs/$6760=0.00962rugs/$

b) You have to divide number of rugs produced with total expense.

In order to calculate the total expense, you have to add every expense.

The solvent expense can be calculated multiplying the number of gallons with the price per gallon:

solvent expense=100gallons*5$/gallon=$500

The machine rental expense can be calculated calculated multiplying the number of days with the price per day.

machine rental expense = 20days*50$/day=$1000

So here is the sum:

total expense=labor expense+solvent expense+machine expense

=$6760+$500+$1000=$8620

multi-factor productivity=65 rugs/8620$=0.00754rugs/$
