Answer:

A poly nomial is an expression with more than one term.

Step-by-step explanation:

Terms are separated by +'s and -'s. So, anything that has multiple terms and are polynomials(poly: the greek root for many.)

If an expression has a division, and the denominator(the number under) is a variable(x,y,z, etc.), then it is not a monomial. Thus it is a polynomial.

So to sort of answer your question if you're one of those people who just look to the bottom for answers to be lazy, I see 3 polynomials.

How many rays intersect at point O 1. 5 2. 4 3. 6 4. 3

stiks02 [169]

For this case, what you should see is which lines contain point O.
We have then that the lines that contain this point are:
EC
AD
BO
We note that three lines contain point O.
Therefore, three lines intersect at the same point.

You are dealt a hand of three cards, one at a time. Find the probability of each of the following. a) The first heart you get

boyakko [2]

Answer:

a) 0.145

b) 0.013

c) 0.783

d) 0.586

Step-by-step explanation:

a) there are always 52 cards in total, 13 hearts

Pa = 39/52 × 38/51 × 13/50 = 19266/132600 = 257/1700 =0.145

b) there are always 13 diamonds in a complete card

Pb = 13/52 × 12/51× 11/50 = 11/850 = 0.013

c) there are always 4 aces, and 48 that are not aces

Pc = 48/52 × 47/51 × 46/50 = 4324/5525 = 0.783

d) there are 13 hearts,to get at least one heart we have.

Pd = 1 - p

Where p is the probability of no hearts

p = 39/52 × 38/51 × 37/50 = 703/1700 = 0.414

Pd = 1 - 0.414

Pd = 0.586

Which list has a mean of 21 and median of 20

Each of the list have 5 numbers and they've all been sorted.

The median is the number at the 3rd position (i.e. the middle number)

So, list C and D are out because they do not have a median of 20.

Next, calculate the mean of lists A and B

$\bar x = \frac{\sum x}{n}$

A. 18, 20, 20, 22, 25

$\bar x = \frac{18 + 20 + 20 + 22 + 25}{5}$

$\bar x = \frac{105}{5}$

$\bar x = 21$

B. 20, 20, 20, 25, 25

$\bar x = \frac{20 + 20 + 20 + 25 + 25}{5}$

$\bar x = \frac{110}{5}$

$\bar x = 22$

Only list A has a median value of 20 and a mean value of 21

What are the zeros of the quadratic function f(x) = 6x2 – 24x + 1?

seraphim [82]

Answer:

$x=\frac{12+\sqrt{138}}{6}\:\:or\:\:x=\frac{12-\sqrt{138}}{6}$

Step-by-step explanation:

$f(x)=6x^2-24x+1\\\\0=6x^2-24x+1\\\\x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x=\frac{-(-24)\pm\sqrt{(-24)^2-4(6)(1)}}{2(6)}\\ \\x=\frac{24\pm\sqrt{576-24}}{12}\\\\x=\frac{24\pm2\sqrt{138}}{12}\\\\x=\frac{12\pm\sqrt{138}}{6}$
