One hundred thousand, or in this case, four hundred thousand.
Answer:
(1 - 4x)³
Step-by-step explanation:
The first 2 terms are a difference of cubes and factor in general as
a³ - b³ = (a - b)(a² + ab + b²), thus
1 - 64x³
= 1³ - (4x)³
= (1 - 4x)(1 + 4x + 16x²)
Thus
1 - 64x³ + 48x² - 12x ← factor out 12x from each of the 2 terms
= (1 - 4x)(1 + 4x + 16x²) + 12x(4x - 1) ← factor out - 1 from (4x - 1)
= (1 - 4x)(1 + 4x + 16x²) - 12x(1 - 4x) ← factor out (1 - 4x) from the terms
= (1 - 4x)(1 + 4x + 16x² - 12x)
= (1 - 4x)(1 - 8x + 16x²) ← perfect square
= (1 - 4x)(1 - 4x)²
= (1 - 4x)³ ← in factored form
Answer:
0.60
Step-by-step explanation:
find the probability it is a 2:
0.40 / 1 = 0.4 or 40%
find the probability it isn't a 2:
1 - 0.4 = 0.6
1) The ratio of used books to all books is 6:14
2) The ratio of used books to new books is 6:8
Answer:
64.0% is the correct answer.
Step-by-step explanation:
As per the given scatter plot of voter turnout every year:
X axis represents the year and
Y axis represents the percentage of people who voted.
The model was predicted as per the equation:
<u>To find:</u> Prediction for the year 1900.
Putting the value of 
, the value of y will be the predicted value of the model i.e. the value of percentage of voter turnout.
So, the model predicts 
for the year 1900.
