Choose the correct simplification of (4x − 3)(3x2 − 4x − 3).

Mathematics
1 answer:
Korolek [52]2 years ago

the expression simplified is:

12x^3 - 25x^2 + 9

<h3>How to simplify the given expression?</h3>

Here we have the expression:

(4x - 3)*(3x^2 - 4x - 3)

We just need to distribute the product, we will get:

(4x - 3)*(3x^2 - 4x - 3)\\\\(4x)*(3x^2 - 4x - 3)  - 3*(3x^2 - 4x - 3)\\\\12x^3 - 16x^2 - 12x - 9x^2 + 12x + 9

Now we just need to group terms with the same exponent of x:

12x^3 - 16x^2 - 12x - 9x^2 + 12x + 9\\\\12x^3 + (-16 - 9)x^2 + (-12 + 12)x + 9\\\\12x^3 - 25x^2 + 9

That is the expression simplified

Helppp. Write an equation to solve for a. Then find the missing angle.
kvasek [131]

Answer:

180 = 90 + 52+ a

38 =a

Step-by-step explanation:

The sum of the angles of a triangle add to 180 degrees

180 = 90 + 52+ a

Combine like terms

180 = 142+a

Subtract 142 from each side

180 -142 = 142+ a -142

38 = a

In a random sample of 2500 sports fans, 61% prefer basketball over soccer.
timama [110]

The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The Margin of error in this survey is 1%.

<h3>What is the margin of error?</h3>

The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The wider the margin of error, the less confident one should be that a poll result reflects the outcome of a population-wide survey.

The random sample of 2500 sports fans, out of which 61% prefer basketball over soccer, therefore, we can write n=2500 and p=0.61. Thus, the margin of error can be written as,

MOE=\sqrt{\dfrac{\hat p(1-\hat p)}{n}} = \sqrt{\dfrac{0.61(1-0.61)}{2500}} = 0.00975 = 0.975\% \approx 1\%

Hence, the Margin of error in this survey is 1%.
