Step-by-step explanation:

The "experimental probability" is the ratio of actual outcomes of interest to the number of trials. It is based on actually performing the selection over and over some number of times. The "theoretical probability" will be the fraction that is the outcomes of interest divided by the total number of possible outcomes.

We note that Mel's purse contains a total of 6 +8 +4 +7 = 25 coins. The theoretical probability of selecting any given coin is then 1/25.

A. The experimental probability of selecting a dime is ...

number of dime outcomes / number of trials = 30/150 = 1/5

B. The theoretical probability of selecting a dime is ...

(4 dimes)/(25 coins) = 4/25

C. The assumption in probability experiments is that randomly selected outcomes will always approach the theoretical probability in their frequency of occurrence.

See the attachment for the appropriate answer choices.

A. The experimental probability of selecting a penny is ...

number of penny outcomes / number of trials = 45/200 = 9/40

B. The theoretical probability of selecting a penny is ...

(6 pennies)/(25 coins) = 6/25

C. The difference between these values is ...

6/25 -9/40 = 48/200 -45/200 = 3/200

Answer:

a = 250

b = 10

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Step-by-step explanation:

Step 1: Define

[tex]a=\frac{5x^2}{2}[/tex]

[tex]b=\frac{2x^2(x-5)}{10x}[/tex]

x = 10

Step 2: Evaluate

Substitute in x: [tex]a=\frac{5(10)^2}{2}[/tex]Exponents: [tex]a=\frac{5(100)}{2}[/tex]Multiply: [tex]a=\frac{500}{2}[/tex]Divide: [tex]a=250[/tex]

Substitute in x: [tex]b=\frac{2(10)^2(10-5)}{10(10)}[/tex]Exponents: [tex]b=\frac{2(100)(10-5)}{10(10)}[/tex]Subtract: [tex]b=\frac{2(100)(5)}{10(10)}[/tex]Multiply: [tex]b=\frac{1000}{100}[/tex]Divide: [tex]b=10[/tex]

I think A is 250 and B is 10

Hahn Company uses a job-order costing system. Its plantwide predetermined overhead rate uses direct labor-hours as the allocation base. The company pays its direct laborers $18,50 per hour. During the year, the company started and completed only two jobs-- Alpha, which used 62,300 direct labor-hours, and Job Omega. The job cost sheets for the these two jobs are shown below.

Answers

Answer:

1. $7 per DLH

2. Total Job Cost = $1,638,000

Step-by-step explanation:

Note: Question is incomplete and similar question is attached as picture below

1. Direct Labor Hours - Omega = $331,800 (Direct Labor) / $14 per Hour (Direct Labor Rate per hour)

Direct Labor Hours - Omega = 23,700 hours

Predetermined Overhead Rate = $165,900 (Applied Manufacturing Overhead) / 23,700 (Direct Labor Hours)

Predetermined Overhead Rate = $7 per DLH

2. Job Cost Sheet for Job Alpha

Direct Material $428,400

[$1,638,000 - ($806,400 + $403,200) ]

Direct Labor $806,400

(57,600 hrs * $14)

Manufacturing Overhead applied $403,200

(57,600 hrs * $7)

Total Job Cost $1,638,000

thanks

the attachment is the question

Answers

Answer:

Answer:

x = - 45 / 74

Step-by-step explanation:

6 / x + 10 = 2 / 15

6 / x = 2 / 15 - 10

6 / x = 2 / 15 - 150 / 15

6 / x = - 148 / 15

6 = ( - 148 / 15 ) x

6 ( 15 / - 148 ) = x

x = 90 / - 148

x = - 45 / 74

If m is the midpoint of CD, CM= 4x-5, and md=2x +5, find CM

Answers

Answer:

CM = 15

Step-by-step explanation:

since M is the midpoint of CD , then

CM = MD , that is

4x - 5 = 2x + 5 ( subtract 2x from both sides )

2x - 5 = 5 ( add 5 to both sides )

2x = 10 ( divide both sides by 2 )

x = 5

Then

CM = 4x - 5 = 4(5) - 5 = 20 - 5 = 15
