Step-by-step explanation:

Morning is 4 hr 15 min

afternoon is 4 hour 15 min

together is 8 hour 30 min

8.5*14 = 119 dollars

According to the unitary method, the wage of the weekly time for the employee is written as $119.00

To calculate the hours worked on Monday, we need to consider both the morning and afternoon shifts. For the morning shift, the employee clocked in at 08:00 AM and clocked out at 12:15 PM. The total time worked in the morning is 4 hours and 15 minutes (12:15 - 08:00).

Similarly, for the afternoon shift, the employee clocked in at 01:00 PM and clocked out at 05:15 PM. The total time worked in the afternoon is 4 hours and 15 minutes (05:15 - 01:00).

Adding both morning and afternoon hours, the total hours worked on Monday is

(4 hours 15 minutes + 4 hours 15 minutes) = 8 hours and 30 minutes

To perform the calculation, we need to convert the minutes to decimal hours. There are 60 minutes in an hour, so we divide the minutes by 60 to get the decimal representation. In this case, 30 minutes is equal to 0.5 hours.

Now that we have the total hours worked on Monday, we can calculate the pay. We multiply the total hours worked by the hourly wage. In this case, the hourly wage is $14/hr.

So, the pay for Monday would be:

Pay = Total hours worked x Hourly wage

Pay = 8.5 hours x $14/hr = $119.00

A light bulb manufacturing process results in 6% of the light
bulbs being defective. If 5 light bulbs are randomly
selected, find the probability that all of the light bulbs are
fully functioning.

Answers

Answer:

[tex]Probability = 0.734[/tex]

Step-by-step explanation:

Given

Represent the event that a bulb is defective with p.

So:

[tex]p =6\%[/tex]

Required

Determine the probability that all 5 are fully functioning

Represent the event that a bulb is defective with q.

So:

[tex]p + q = 1[/tex]

Make q the subject

[tex]q = 1 - p[/tex]

Substitute 6% for p

[tex]q = 1 - 6\%[/tex]

Convert % to decimal

[tex]q = 1 - 0.06[/tex]

[tex]q = 0.94[/tex]

If 5 were selected and all are functioning, the event is represented as: q q q q q

And the probability is:

[tex]Probability = q * q * q * q *q[/tex]

[tex]Probability = q^5[/tex]

Substitute 0.94 for q

[tex]Probability = 0.94^5[/tex]

[tex]Probability = 0.7339040224[/tex]

[tex]Probability = 0.734[/tex] --- approximated

Step-by-step explanation:

3(2-5) – (4w=11)

Distributive property

6 - 15 - 4w = 11

Combine like terms

-9 - 4w = 11

Add 9 on both sides

-9 + 9 - 4w = 11 + 9

-4w = 20

Divide by -4 on both sides to isolate the variable

-4w/-4 = 20/-4

w = -5
