Answer:

  • -32x² +8x -8
  • See below about the process

Step-by-step explanation:

The simplified expression is ...

  3x(x -12x) +3x² -2(x -2)²

  = 3x(-11x) +3x² -2(x² -4x +4) . . . . . simplify contents of parentheses

  = -33x² +3x² -2x² +8x -8 . . . . . . . .eliminate parentheses

  = (-33 +3 -2)x² +8x -8 . . . . . . . . . . group the coefficients of like terms

  = -32x² +8x -8

Answer:

Options (1),(3),(4) are correct and Options (2) and (5) are incorrect.

Step-by-step explanation:

3x(x-12x)+3x^{2}-2(x-2)^{2}

=3x(x-12x)+3x^{2}-2(x^{2}-4x+4)=3x^{2}-36x^{2}+3x^{2}-2x^{2}+8x-8=[tex]-32x^{2}+8x-8

In this question we do the the simplification of term -2(x-2)^2 by squaring (x-2) then we find simplified product is not a binomial.

After multiplying, the like terms are combined by adding and subtracting.

The parentheses are eliminated through multiplication and then

The final simplified product is -32x^{2}+8x-8

Therefore Options (1),(3),(4) are correct and Options (2) and (5) are not correct.

Suppose you are taking the bus home, and can take either Route 51 or Route 82. You know that the Route 82 will arrive at the bus
kykrilka [37]

Answer:

E[T] = 10

Step-by-step explanation:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distribution has two bounds, a and b, and the expected value of the uniform distribution is given by:

E = \frac{a+b}{2}

Uniformly distributed between 0 and 20 minutes.

This means that a = 0, b = 20

Let T be the number of minutes you wait until you board a bus. Find E[T].

This is

E[T] = \frac{a + b}{2} = \frac{0 + 20}{2} = 10

E[T] = 10
