Answer: 10 days

Step-by-step explanation:

The total number of hours worked is 10 x 2 x 5 which is 10 hours

So two people working 5 hours is 2 x 5 which is 10 hours.

So to get 100 hours they have to work 10 days

Answer:

10 days.

Step-by-step explanation:

10 workers working 5 *2 = 10 hours do the job.

So 1 worker will take 100 hours to do the job.

2 workers will take 50 hours.

- so they will take 10 *  5  days.

The weight of an organ in adult males has a​ bell-shaped distribution with a mean of 325 grams and a standard deviation of 25 gr
vampirchik [111]

Answer:

(a) between 300 grams and 350 grams  (b) 95%  (c) 5%  (d) 83.85%

Step-by-step explanation:

We have that \mu = 325 grams and \sigma = 25 grams. Let's compute the following figures to use the empirical rule

\mu + \sigma  = 325 + 25    = 350  

\mu + 2\sigma = 325 + 2(25) = 375  

\mu + 3\sigma = 325 + 3(25) = 400  

\mu - \sigma  = 325 - 25    = 300  

\mu - 2\sigma = 325 - 2(25) = 275  

\mu - 3\sigma = 325 - 3(25) = 250  

using the image below that was made it with help of the empirical rule we find the next figures

(a) About 68% of organs will be between 300 grams and 350 grams

(b) 95% of organs weights between 275 grams and 375 grams

(c) 5% of organs weights less than 275 grams or more than 375 grams

(d) 83.85% of organs weights between 300 grams and 400 grams

If 5,000 beef cattle were slaughtered in one day at Tyson Foods and the average animal weight was 1,350 lbs. How many pounds of
krok68 [10]

Answer:

33,750,000 pounds of animals were processed during 5 days.

Step-by-step explanation:

If the average animal weight is 1350 lbs and 5,000 beef are slaughtered in one day, the total amount for one day would be: (1350)(5000) = 6,750,000 lbs.

Now we need to multiply this number by five since we want to know the total of pounds of animals processed during 5 days.

6,750,000 (5) = 33,750,000 pounds of animals.

The ratio of Holly's age to that her aunt is 4:9. When holly was born her aunt was 15 years old. How old is holly's aunt now?
Lyrx [107]

Answer:

27 years

Step-by-step explanation:

Let Holly's age be h and Aunt's age be a. We can setup 2 equations and solve.

1. \frac{h}{a}=\frac{4}{9}

2. a - 15 = h

We can plug in equation 2 into equation 1 to solve for aunt's age:

\frac{h}{a}=\frac{4}{9}\\\frac{a-15}{a}=\frac{4}{9}\\9(a-15)=4a\\9a-135=4a\\5a=135\\a=\frac{135}{5}=27

Holly's aunt's age is 27
