5.9/2=2.95x3.14=9.263=9.26
Answer:
can be either a representation of the entire or a sample of a population. Descriptive statistics are broken down into measures of central tendency and measures of variability (spread).
Step-by-step explanation:
Firstly expand (x - 3)(ax^2 + bx + c):
ax^3 + bx^2 + cx - 3ax^2 - 3bx - 3c
Now rearrange it so that it's in the form ax^3 + bx^2 + cx + d:
ax^3 + (b-3a)x^2 + (c-3b)x - 3c
Now we can compare both equations:
ax^3 + (b-3a)x^2 + (c-3b)x - 3c = 2x^3 - x^2 - 19x + 12
We get:
(1) a = 2
(2) b - 3a = -1
(3) c - 3b = -19
(4) -3c = 12
If we substitute (1) into (2) we get:
b - 3*2 = -1
b - 6 = -1
b = 5
Now if we solve (4) we get:
-3c = 12
c = -4
Therefor a = 2, b = 5 and c = -4
There is decrease of 35% in the price of silver in the past 6 months.
<u>
Solution:
</u>
Given that
Price of silver went from $26.40 a troy ounce down to $17.16 a troy ounce during past 6 months need to represent this decrease in percentage
Price of silver before 6 months = initial price = $26.40
Price of silver now = current price = $17.16
Difference in price in 6 months = 26.40 – 17.16 = $9.24


Hence there is decrease of 35% in the price of silver in the past 6 months.
