The credit department of Lion's Department Store in Anaheim, California, reported that 30% of their sales are cash, 30% are paid

Oliga [24]

Answer:

Hence the probability that she paid cash is 0.105

Step-by-step explanation:

P(cash) = 0.3

P(credit card ) = 0.3

P(debit card ) = 0.4

P ( more than $50 | cash ) = 0.2

P (more than $50 | credit card ) =0.9

P (more than $ 50 |debit card ) = 0.6

P ( more than $50) = P ( more than $50 | cash )* P (cash) + P (more than $50 credit card ) * P(credit card ) + P (more than $ 50 |debit card )* P(debit card )

= 0.2 * 0.3 + 0.9 * 0.3 + 0.6* 0.4

= 0.57

P ( more than $50) = P ( more than $50 | cash )* P (cash) / P ( more than $50)

= 0.2* 0.3 / 0.57

= 0.105

It takes 24 megabytes to store 144 songs on a music player. What is the greatest number of songs that 60 megabytes could store?

givi [52]

Option B

We can store a total of 360 songs in 60 megabytes of space.

Solution:

It is given to us that It takes 24 megabytes to store 144 songs on a music player. We have been asked to find out what is the greatest number of songs that 60 megabytes could store.

To solve this question we can use the unitary method.

We will first find out how many songs can be stored in 1 megabyte. This can be done as follows:

$=\frac{144}{24}=6$

Therefore, we can store 6 songs in 1 megabyte.

So, in 60 megabyte we can store the following number of songs:

$=60 \times 6=360$

So, we can store a total of 360 songs in 60 megabytes.

kondaur [170]

Step-by-step explanation:

$21=per hour mowling

$17=per hour gardening

only work 16 hours per week

Goals =$275 per week

$275÷16 hours=$17.1875(Each hour in a week)

mow lawns= $17.1875 ×$12=$206.25(for 16 hours)

gardening=$17.1875 ×$17=$292.1875(for 16 hours)

mowling lawns=$275÷$21=13.0952380952(13 hours,12 minutes and 30 seconds)

Gardening =$275÷$17= $16.1764705882 (970 hours,9 minutes,80 seconds)
