Work the following pricing problems for services rendered. (Round to tenths.)Labor rate = $8.00 per hour
Labor time = 6 hours
Retail price of parts = $0
Total job cost = $86.00
Overhead rate?

Answers

Answer:

Overhead rate = $6.3

Step-by-step explanation:

Given : Labor rate = $8.00 per hour


Labor time = 6 hours


Retail price of parts = $0


Total job cost = $86.00

To find : Overhead rate

Solution:

Overhead cost =  Total Cost - The cost of all inputs

The Overhead Rate is this number divided by total labor hours.

Total job cost = $86.00

Labor Cost = labor rate × labor time = 8 × 6 = $48

Retail price of parts:$0

Overhead Costs = total cost - labor cost= $86 - $48 = $38

Now, we divided overhead cost by labor hours to get overhead rate,

Overhead Rate =(38)/(6)=6.33

Therefore, Overhead rate is $6.3

Answer:

55.8

Step-by-step explanation:

8x6= 48

48/86 into percent= 55.814%

therefore it would be rounded to 55.8

A large pharmaceutical company is trying to determine whether a drug aptly named Recall-Pro can increase your short-term memory capacity. The company prepares a double-blind study as follows:Step 1: A randomly selected pool of individuals is brought to a clinic and is evaluated for any existing health conditions that may impair the results of this experiment.

Step 2: The remaining individuals are split into two groups: a treatment group and a control group.

Step 3: The control group receives a placebo, but neither the researcher nor the individuals know this.

Step 4: The treatment group receives Recall-Pro, but neither the researcher nor the individuals know this.

Which step is flawed in the double-blind study? Why?
A.Step 1; health screening should not eliminate participants from the study
B.Step 2; it does not specify whether the two groups are chosen randomly
C.Step 3; the control group does not receive the placebo
D.Step 4; members of the treatment group should know that they have received the medication

Answers

The best answer to the question that is being stated above would be letter B. Step 2 is the one that is flawed in the double-blind study because it does not specify that the two groups were randomly chosen. It is important to assign the participants randomly so that the results give a non-confounded result.

How to multiply 25 by 5 without using calculator?

Answers

Hey There

In multiplication you have to know the process of regrouping, which means to take away from tens. Also, you multiply from left to right.

Steps
1. First multiply 5*5=25, the two adds to the product of 5*2 

2. Now you have to multiply 5*2=10, now you have to add two because of regrouping, 10+2=12, so you're final answer is 125.

In conlusion, 25*5=125

Hope this helps :)
   2      5

×          5
___________
 1    2    5
____________

1st step:  5 × 5 = 25.  Put down 5 . Keep 2 aside.

2nd step:  5 × 2 = 10. 10 plus the 2 kept aside = 12

3rd step :  write down 12.

That brings the answer to 125.
