1. The present population of a certain city is 66,550. If 3 years ago, the population of the city was 50,000, find the annual population growth rate.
Jawaban:
To find the annual population growth rate, we need to determine the difference in population between the current population and the population 3 years ago, and divide that number by the number of years that have passed. Then, we need to divide that number by the initial population and multiply by 100% to express the result as a percentage.
The difference in population between the current population and the population 3 years ago is 66,550 - 50,000 = 16,550.
The annual population growth rate is (16,550 / 3) / 50,000 * 100% = 5.5%. This means that the population of the city is increasing by 5.5% per year.

7. POIN 100 lhooo......... TWO years ago. the sum of the ages of a boy and his younger sister was 20 years. THREE years from now. their ages wikl differ by 10 years. From a pair of simultaneous equations and find their present ages??
for example: boy's age = x and his sister = y, so
(x - 2) + (y - 2) = 20
x - 2 + y - 2 = 20
x + y - 4 = 20
x + y = 20 + 4
x + y = 24 ... first equation
(x + 3) - (y + 3) = 10
x + 3 - y - 3 = 10
x - y = 10 ... second equation
now eleminate them
x + y = 24
x - y = 10 +
2x = 34
x = 17
then, substitute
x + y = 24
17 + y = 24
y = 24 - 17
y = 7
so, present the boy is 17th and his sister is 7 years old
hopefully help you :)

11. The sum of the ages of Tom and Jerry now is 52 years. If Tom is 4 years older than Jerry. The correct statement below is … * Two years later,Tom will be 30 years old. Three years ago, the sum of their ages was 49 years. Now, Jerry is 28 years old. Two years ago, Jerry was 26 years old. dikasih tau caranya
Jawaban:
Tom as T
Jerry as J
T+J = 52
T = 52-J
T = 4+J
4+J = 52-J
4 + 2J = 52
2J = 52 - 4
2J = 48
J = 24
T = 4+J
T = 4 + 24 = 28
answer (A) Two years later,Tom will be 30 years old.
12. What was the most destructive impact of the toba eruption around 74000 years ago?
Behind the lagoon of Lake Toba that spans across North Sumatra, an enormous destructive force is hidden in it. Finally, about 74,000 years ago, Mount Toba erupted and almost finished humanity. The eruption known as the Youngest Toba Tuff (YTT) is the most powerful and forms a lake (caldera) as it is today. Releasing at least 2,800 cubic miles of magma into the air, YTT's eruption became the largest on Earth in the last two million years.

18. A recent study of 26 Conway, SC, residents revealed they had lived at their current address an average of 9. 3 years. The standard deviation of the sample was 2 years. A. What is the population mean? b. What is the best estimate of the population mean? c. What is the standard error of estimate? d. Develop a 90 percent confidence interval for the population mean.
Jawab:
a. The population mean adalah rata-rata dari seluruh anggota populasi yang ingin diteliti. Dalam kasus ini, kita tidak memiliki informasi tentang seluruh anggota populasi yang terdiri dari seluruh penduduk Conway, SC, sehingga tidak dapat menghitung population mean dengan pasti.
b. The best estimate of the population mean adalah perkiraan terbaik dari population mean yang didasarkan pada data sampel yang tersedia. Dalam kasus ini, the best estimate of the population mean adalah 9.3 tahun, yang merupakan rata-rata dari 26 orang penduduk Conway, SC, yang disurvei.
The standard error of estimate adalah ukuran tingkat ketidakpastian dari perkiraan terbaik population mean yang didasarkan pada data sampel. Standard error dapat dihitung dengan rumus:
standard error = standard deviation / √n
Dalam kasus ini, standard error adalah:
standard error = 2 / √26
= 0.46
A 90 percent confidence interval for the population mean adalah rentang nilai yang terdiri dari perkiraan terbaik population mean ditambah dan dikurangi dengan nilai confidence interval. Confidence interval dapat dihitung dengan rumus:
confidence interval = standard error x z-score
Z-score adalah nilai yang menunjukkan seberapa jauh nilai dari mean dari sebuah distribusi normal. Nilai z-score dapat dicari di tabel z-score atau dengan menggunakan fungsi z-score pada calculator atau spreadsheet. Untuk menghitung 90 percent confidence interval, kita menggunakan z-score dengan tingkat kepercayaan 90%, yaitu 1.645.
Jadi, 90 percent confidence interval dari population mean adalah:
confidence interval = 0.46 x 1.645
= 0.75
Sehingga, 90 percent confidence interval untuk population mean adalah 8.55 - 9.05. Artinya, ada kemungkinan sebesar 90% bahwa population mean berada di rentang 8.55 - 9.05 tahun.
