The temperature of an enclosure for a pet corn snake should be an average of 81° F. For the well-being of the corn snake, the te

Answer:

0.8 or 80%

Step-by-step explanation:

Let A and B denote the different events

A: “The concert attendee visited Orlampa Skydome”

B: “The concert attendee visited the Bithlo Megaplax”

Thus, the probability P(A) of a concert attendee visiting Orlampa Skydome is

P(A) = 120/200 = 0.6

In a similar manner,

P(B) = 100/200 = 0.5

We seek to determine P(A∪B), which represents the odds that a concert attendee went to either Orlampa Skydome OR the Bithlo Megaplax.

We know that

P(A∪B) = P(A) + P(B) - P(A∩B)

but P(A∩B) signifies the possibility that a concert attendee went to both Orlampa Skydome AND the Bithlo Megaplax.

Given that the events are independent,  

P(A∩B) = P(A)P(B) = 0.6*0.5 = 0.3

and

P(A∪B) = 0.6 +0.5 - 0.3 = 0.8 or 80%

Answer:

Her accumulated earnings for the month total $2208

Step-by-step explanation:

A dental lab technician receives $14 hourly for day shifts and $18 hourly for night shifts.

During one month:

She completed six 4-hour day shifts

Thus, total hours worked =

Three 8-hour day shifts =

Three 10-hour day shifts =

Total day hours = 24+24+30=78 hours

Hourly rate for daytime work = $14

Cost for 78 day hours =

Five 6-hour night shifts=

Four 8-hour night shifts =

Total night hours = 30+32=62 hours

Hourly rate for nighttime work = $18

Cost of 62 night hours =

Thus, total monthly earnings = $1092+$1116 = $2208

Consequently, her total pay for the month amounts to $2208

I think the rule to follow is to multiply the first number by the second and then add the first number. For example:
in the case of the first one, 1 x 4 = 4, then 4 + 1 = 5
for the second one, 2 x 5 = 10, and then 10 + 2 = 12...
So for 8+11:
simply multiply 8 x 11 = 88, and then add 88 + 8 = 96

The answer I arrived at is related to paging.
