cars can be parked in the building?

So, all we have to do here is multiply:

First, the amount of car spaces by the amount of rows:

38 x 4 = 152  

This is the number of parking spots per level.

Then, the number of levels by the number of parking spots on each level:

152 x 7 = 1064

So, a total of 1,064 cars can be parked in this building!

Jeremy is going on rides at a carnival he starts the rides a 12:30 by 12:45 he had gone on 1/5 of the carnival rides at the rate
MArishka [77]

Answer:

1.25 hours or 1 hour and 15 minutes

Step-by-step explanation:

12:45 - 12:30 = :15

15 minutes equates to 1/5 of the rides

So, we multiply 15 by 5 to find the total time taken to ride all the rides.

15 x 5 = 75

75/60 = 1.25

It would take him 1.25 hours to ride all the rides at the carnival or 1 hour and 15 minutes.

Jenna earns $8.75 per hour working at the mall. If Jenna worked hours 20 1/5 last week, how much did she earn before taxes were
Elena-2011 [213]
To find out the amount Jenna earns, you need to multiply how much she earns per hour by the amount of hours she works for.

If she earns $8.75 for 1 hour, and works for 20 1/5 hours, she'll earn:
8.75 x 20 1/5 = 176.75

Jenna earns $176.75 before tax.

Suppose odd numbers 1, 3, 5 with probability C and on each of the even numbers with probability 2C.
posledela

Answer:

Step-by-step explanation:

a) Odd numbers if n then even numbers also n

Total prob = 1 gives 3c=1

c=1/3

b) X=1, if even and

    0, if odd

Y =1, if x >3 and

  =0 otherwise

xy can take values as 0 or 1

xy =1 if x even and y is greater than 3, or favorable outcomes are

4, 6.

xy= 1 if die shows 4 or 6

  =0 if otherwise

Prob (xy) = 1/3, for xy =1 and

               = 2/3 for xy =0

This is binomial since each trial is independent.

If 12 tosses are made then if we have binomial proba

with n =12 and p = 1/3 for success
