Answer:

1/15

Step-by-step explanation:

When the bag is full (of 10 marbles), there are 3 pink marbles. Thus, the probability of drawing a pink marble is 3/10.

We don't replace that pink marble. So now we have 9 marbles instead of 10. We now have 2 pink marbles in the bag. The probability of drawing a pink one now is 2/9.

Thus, the probability of drawing 2 pink marbles in a row is (3/10)(2/9), or

6/90, or 1/15

What is the complete factorization of the polynomial below x^3+2x^2+4x+8

vagabundo [1.1K]

Answer:

c) (x + 2)(x + 2i)(x - 2i)

Step-by-step explanation:

x^3 + 2x^2 + 4x + 8

= (x^3 + 2x^2) + (4x + 8)

= x^2( x + 2) + 4(x + 2)

= (x + 2)(x^2 + 4)

= (x + 2)(x^2 - 4i^2) ---------------------------->(i^2 = -1)

= (x + 2)(x + 2i)(x - 2i)

An angle measure is 72.3 degrees. What is the measure of its complement? (I already tried 17.7 and that’s not correct).

Answer:

I got 17.7°

Step-by-step explanation:

Since a complimentary angle adds up to 90 degrees, this would be the right answer... does it require a degree symbol?

Orthogonalizing vectors. Suppose that a and b are any n-vectors. Show that we can always find a scalar γ so that (a − γb) ⊥ b, a

jeka57 [31]

Answer:

$\\ \gamma= \frac{a\cdot b}{b\cdot b}$

Step-by-step explanation:

The question to be solved is the following :

Suppose that a and b are any n-vectors. Show that we can always find a scalar γ so that (a − γb) ⊥ b, and that γ is unique if $b \neq 0$ . Recall that given two vectors a,b a⊥ b if and only if $a\cdot b =0$ where $\cdot$ is the dot product defined in $\mathbb{R}^n$ . Suposse that $b\neq 0$ . We want to find γ such that $(a-\gamma b)\cdot b=0$ . Given that the dot product can be distributed and that it is linear, the following equation is obtained
