Suppose that Bob leaves a job that pays $100,000 per year in order to open a new sponge business. His insurance cost is $8,000,

tensa zangetsu [6.8K]

Answer:

-$11,000 is the economic profit or we can say it is a loss.

Step-by-step explanation:

The job paid Bob = $100000

The insurance cost is = $8,000

The material cost is = $15,000

The lease payments are = $8,000

The sales revenue is $120,000.

So, Bob's economic profit is: $120000-100000-8000-15000-8000=-11000$

Therefore, his economic profit is -$11000.

Taylor surveys students in one grade level who own at least one pet. She finds that 50% of the students surveyed own 2 pets, 3 s

Rasek [7]

Answer:

Step-by-step explanation:

We know that half of the students has two pets. The rest of the students make up the other half. So, we have 3 students + 2 students + 8 students = 13 students that make half of the sample population

That means total number of students being surveyed is 13+13=26 students

Then we work out the probability

P(One pet) = 8/26 = 4/13

P(Two pets) = 1/2

P(Three pets) = 3/26

P( Four pets) = 2/26 = 1/13

The probability distribution is shown in the table below. Let be the number of pets and is the probability of owning the number of pets

The ratio of men to women is 5 to 8. If there are 286 employees total how many women work for the company ??

Brut [27]

Answer:

There are 176 women in the company.

Step-by-step explanation:

Let number of men are 5x and number of women are 8x.

Total number of employees in the company are 286.

But according to given condition, total no of employees are :

$5x+8x = 286\\\\13x=286\\\\x=\dfrac{286}{13}\\\\x=22$

Total no of women are 8x. It means $22\times 8=176$ . Hence, there are 176 women in the company.
