Answer:
24
Step-by-step explanation:
24x0.25=6
Answer:
a. 0.75
b. 0.5526
c. 0.1974
Step-by-step explanation:
Probability is typically expressed as a fraction where the numerator is the number of desired outcomes and the denominator is the total number of outcomes. In this case the suitable parts is the desired outcome and the total shipment is the total parts:
The probability the both the first and second part are suitable:
Since the probability of getting a suitable part the first time is 15/20, then there is one less suitable part and one less part overall to choose on the second time, or 14/19.
Lastly, the probability of choosing a suitable part the first time is again 15/20, but the second part not being suitable would be 5/19:
Answer:
The value of c is 36
Step-by-step explanation:
Now, we fine the perfect square polynomial, we need to have the expression of the form:
so this can be written as a perfect square as:
Now the expression given to us is:
so when c is 36, we will get:
Now, this can be re-written as:
so here we can see that it is of the form:
so the perfect square is:
Hence, when c = 36 we get a perfect square.
This will be a third degree polynomial since we have 3 zeros. We will FOIL them out. They are: (x-2), (x+7i), (x-7i). The product of the second and third factors gives us
. i^2 = -1, so if we simplify, we have
. Now we will multiply that with x-2 to get
. There you go!
Answer:
IDR 480,000
Step-by-step explanation:
Persentase diskon = Harga lama - Harga baru / Harga lama
Harga lama = Harga sebelum diskon = x
Harga Baru = IDR 336000
Persentase diskon = 30%
Karenanya:
30% = x - 336000 / x
30/100 = x - 336000 / x
0.3 = x - 336000 / x
Cross Multiply
0.3 × x = x - 336000
0.3x = x - 336000
x - 0.3x = 336000
0.7x = 336000
x = 336000 / 0.7
x = IDR 480,000
