Answer:

Step-by-step explanation:

first we turn ur mixed number into an improper fraction

1 1/4 = 5/4

the reciprocal of 5/4 can be found by just flipping it....so the reciprocal is gonna be 4/5

so 1 1/4 subtracted from its reciprocal is :

4/5 - 5/4 =

16/20 - 25/20 =

- 9/20 <====

A blank CD can hold 70 minutes of music. So far you have burned 25 minutes of music onto the CD. You estimate that each song las
zaharov [31]

Answer:

The possible numbers of songs that you can burn onto the CD is 11.

Step-by-step explanation:

The total storage capacity of CD =  70 minutes

Storage already used = 25 minutes

Hence, The available storage =  Total available  storage -  Used Storage

= 70 minutes - 25  minutes = 45 minutes

Hence, the CD has 45 minutes storage left.

Now, each song takes up 4 minutes of storage.

⇒ \textrm{Total number of songs possible} =  \frac{\textrm{Total storage left}}{\textrm{Time taken by each song}}

= \frac{45 minutes}{4minutes }  = 11.25

⇒The number of songs possible = 11.25 ≈  11

Hence, the possible numbers of songs that you can burn onto the CD is 11.

1. Suppose half of all newborns are girls and half are boys. Hospital A, a large city hospital, records an average of 50 births
kicyunya [14]

Answer:

5%

Step-by-step explanation:

Hospital A (with 50 births a day), because the more births you see, the closer the proportions will be to 0.5.

Hospital B (with 10 births a day), because with fewer births there will be less variability.

The two hospitals are equally likely to record such an event, because the probability of a boy does not depend on the number of births
