A) there are 48 outcomes and 27 creatures Eric wants to pick. So it would be P= 27/48 which is 56.25%
b) there are 130 coins in total and in those coins there are 10 dimes so it would be P= 10/130 which is 7.7%
c) P(rolling an 8)= 0/6 which is 0% because a die only has 6 outcomes not 8
d) P=5/9 which is 55.5%
To solve this problem you do this:
-first you add 9 to both sides to eliminate the 9
-you then divide by 5 to both sides to get the y by itself
-and your left with y=5

Answer:
400 is the answer
Step-by-step explanation:
Answer:
- Hence, 75.52 percent of the u.s. population had internet access in 2005.
- After 25 years or in the year 2015 89% have internet access.
Step-by-step explanation:
the percent p of the u.s. population with internet access is given by:
25 p-34 t=1378
where t is the number of years after 1990.
- We are asked to find what percent of the u.s. population had internet access in 2005 i.e. we need to find the value of p after 15 years i.e. t=15.
⇒ 25p-34×(15)=1378
⇒ 25p-510=1378
⇒ 25p=1378+510
⇒ 25p=1888
⇒ p=75.52
Hence, 75.52 percent of the u.s. population had internet access in 2005.
- Next we are asked to find in what year will 89% have internet access?
i.e. we have to find the value of t when we are given p=89
⇒ 25×89-34t=1378
⇒ 2225-34t=1378
⇒ 2225-1378=34t
⇒ 847=34t
⇒ or 34t=847
⇒ t=24.9112≈25
Hence after 25 years 89% will have internet access.
i.e. in the year 2015 89% will have internet access.
