An electric technician is paid $9.60 per hour. Based on 40 hours per week, what is this technicians annual salary?

Answers

Answer:  $19968

Step-by-step explanation: Assuming the electric technician works 52 weeks a year with an average of of $40 of paid work, the electrician would make about $19,968 or close to $20,000 a year.

Final answer:

To calculate the technician's annual salary, multiply their hourly rate by the number of hours worked in a week and then multiply that by the number of weeks in a year. In this case, the technician is paid $9.60 per hour and works 40 hours per week.

Explanation:

To calculate the technician's annual salary, we need to multiply their hourly rate by the number of hours they work in a week and then multiply that by the number of weeks in a year.

In this case, the technician is paid $9.60 per hour and works 40 hours per week. So their weekly salary is $9.60 x 40 = $384. To find their annualsalary, we multiply the weekly salary by the number of weeks in a year, which is 52.

Therefore, the technician's annual salary is $384 x 52 = $19,968.

The human resources manager at a company records the length, in hours, of one shift at work, X. He creates the probability distribution below. What is the probability that a worker chosen at random works at least 8 hours?

Answers

With the created probability distribution below, the answer to the question you have presented above would be .6. The probability that a worker chosen at random works at least 8 hours would be  .6. 

The probability that a worker chosen at random works at least 8 hours is 0.84

Data obtained from the question

  • Probability of 6 hours = 0.02
  • Probability of 7 hours = 0.11
  • Probability of 8 hours = 0.61
  • Probability of 9 hours = 0.15
  • Probability of 10 hours = 0.08
  • Probability ofatleast8hours=?

How to determine the probability of at least 8 hours

At least 8 hours simply means 8 hours and above

Thus, the probability of at least 8 hours can be obtained as illustrated below:

P(At least 8 hours) = P(8) + P(9) + P(10)

P(At least 8 hours) = 0.61 + 0.15 + 0.08

P(At least 8 hours) =0.84

A rectangle has a length of 4 2/5 cm and a width of 1 3/10 cm. What is the area of the rectangle?

Answers

If you would like to know what is the area of the rectangle, you can calculate this using the following steps:

the area = a length * a width
x = 4 2/5 cm * 1 3/10 cm
x = 22/5 * 13/10
x = 143/25 = 5 18/25 square cm

The correct result would be 5 18/25 square cm.

guests at a party are seated at 3 tables. small table has 5 seats and 2 pizzas. medium table has 7 seats and 3 pizzas. the large table has 12 seats and 5 pizzas. which table gets most pizza?

Answers

At the small table, the fraction of pizzas per person is:
2/5
Or 40%.

At the medium table, the fraction of pizzas per person is:
3/7
Or about 48%.

At the large table, the fraction of pizzas per person is:
5/12
42%

So, the medium table gets the most pizza.

What is the volume of the cylinder below? A. 72π units³

B. 36π units³

C. 45π units³

D. 90π units³

Answers

Answer:


Step-by-step explanation:

According to the diagram, the radius of this cyl. is 3 and the height is 4 (not 5).  The formula for the volume of a cylinder is:

V = pi*r^2*h.

Here, that volume is V = pi*3^2*4, or 36 pi cubic units.  That's Answer B.

The volume of the right cylinder is \boxed{36\pi {\text{ unit}}{{\text{s}}^3}}.

Further explanation:

The formula for the volume of the cylinder can be expressed as,

\boxed{{\text{Volume}} = \pi {r^2}h}

Here, ‘r” represents the radius of the cylinder and “h” represents the height of the cylinder.

Given:

The radius of the cylinder is {\text{3 units}} and the height of the cylinder is {\text{4 units}} and the slant height is 5{\text{ units}}

The options of the volume are given as follows.

A. {\text{72}}\pi {\text{uni}}{{\text{t}}^3}

B. 36\pi {\text{uni}}{{\text{t}}^3}

C. 45\pi {\text{uni}}{{\text{t}}^3}

D. 90\pi {\text{uni}}{{\text{t}}^3}

Explanation:

The volume of the right cylinder can be obtained as follows,

\begin{aligned}{\text{Volume}} &= \pi {r^2}h\n&= \pi* {\left( 3 \right)^2} * 4\n&= \pi * 9 * 4\n&= 36\pi\n\end{aligned}

The volume of the cylinder is 36\pi {\text{ unit}}{{\text{s}}^3}.

Option A is not correct.

Option B is correct.

Option C is not correct.

Option D is not correct.

Hence, the volume of the right cylinder is \boxed{36\pi {\text{ unit}}{{\text{s}}^3}}.
