1. Sebuah kotak berisi 7 kelereng hijau dan 3 kelereng biru. Jika 3 kelereng diambil secara acak satu persatu tanpa pengembalian , tentukan peluang terambilnya 3 kelereng berwarna biru
Terima kasih
Sebuah kotak berisi 7 kelereng hijau dan 3 kelereng biru. Jika 3 kelereng diambil secara acak satu persatu tanpa pengembalian , tentukan peluang terambilnya 3 kelereng berwarna biru
Pada pengambilan pertama peluang terambilnya kelereng biru = 3/10
Pada pengambilan kedua peluang terambilnya kelereng biru = 2/9
Pada pengambilan pertama peluang terambilnya kelereng biru = 1/8
Jadi peluang terambilnya 3 kelereng berwarna biru = 3/10 x 2/9 x 1/8 = 1/120
1. Diketahui x4 = y4 + 48, x2 + y2 = 6, dan x + y = 2 , nilai x-y adalah ….
Diketahui x4 = y4 + 48, x2 + y2 = 6, dan x + y = 2 , nilai x-y adalah ….
Salah satu alternatif jawaban :
x4 = y4 + 48
<=> x4 - y4 = 48
<=> (x2 + y2)(x2 - y2) = 48
<=> (x2 + y2)(x + y)(x - y ) = 48
<=> 6 x 2 x (x - y ) 48
<=> x - y = 4

Bapak/ibu pengajar tolong bantu saya mengerjakan soal ini,
a.) Sebuah lilin diletakkan 2 cm didepan cermin cekung. Jika bayangannya nyata dan diperbesar 3 kali, maka jarak fokus cermin berapa cm?
b.) Tolong jelaskan konversi satuan Coulomb, mikro Coulomb, dan stat Coulomb (krn, sya selalu bingung dengan ini)
Tolong dijawab secepatnya, dan Terimakasih...
So = 2cm
M = 3x nyata.
Si = M . So = 3 x 2 cm = 6 cm
1/f = 1/So + 1/Si
= 1/2cm + 1/6cm
= 3/6 + 1/6
= 4 / 6
f = 6/4 = 1,5 cm
2. 1 mikro Couloumb = 10-6 Couloumb
Dina memerlukan kacamata berlensa -0,5 dioptri. berapa titik jauh penglihatan mata Dina ?
P = -0,5 dioptri
P = -100/PR
-0,5 = -100/PR
PR = 100 / 0,5
PR = 200 cm
titik jauhnya 200 cm

Dr Suharso, Sp KO,DPH from national AIDS Commission said that only Thailand an Australia have successfully managed to control the increase rate of the number of people with HIV/AIDS. While Indonesia, like many other countries in Asia, is still struggling with the horrific number of new HIV/AIDS cases every year.
It is also reported that the biggest cause of HIV/AIDS transmission is not heterosexual intercourse (39.7 %), or homosexual intercourse (6.2 %), but the use of syringe to inject drugs (40.5 %).
HIV infection is growing most rapidly among the thousands of Indonesians who inject drugs. It is quite common for IDUs (Injecting Drug Users) to share syringes to inject drugs, without taking necessary precautions to sterilize the needs to avoid transmission of diseases. Through this practice a lot of IDUs have caught HIV/AIDS, which they later spread to their spouses and children.
Based on these findings, the National AIDS Commission has launched the campaign to reduce the harm of using drug by injection. The Harm Reduction campaign consists of the following recommendations:
- stop using drug entirely.
- if you cannot stop using drug yet, don’t share syringes with others.
- Make sure you sterilize the syringes before using.
