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.

You subtract 15 from both sides to turn the equation into y = 3x - 15.
Step-by-step explanation:
Given that the set of data collected has an extreme value (24), a Median measure of center is more appropriate than a Mean measure.
We sort the same data collected in increasing order:
{0, 1, 2, 4, 4, 5, 5, 24}
There are 8 elements inside the set, so we check the 4th and 5th elements (closest to the center), which are 4 and 4.
Since they are equal, the Median is 4.
Our answer is Median; 4.
Answer:
72.5
122
Step-by-step explanation:
Half-life for McGill-23 is 145 years. What is the k value?
half of 145 = 72.5
145 - 23 = 122
