One card is selected at random from a deck of cards. determine the probability of selecting a card that is less than 99 or a spa

Kitty [74]

Since these events are independent, you add the possibilities

the number of cards less than 9 is 32
the number of spades is 13
there are 52 cards in a deck, so you put those numbers over 52

32/52 + 13/52 = 45/52

the answer is 45/52

The polynomial of degree 5, P ( x ) has leading coefficient a=1, has roots of multiplicity 2 at x = 3 and x = 0 , and a root of

ser-zykov [4K]

Answer:

$p_{5} (t) = x^{5} - 5\cdot x^{4} + 3\cdot x^{3} +9\cdot x^{2}$ , for $r_{1} = 0$

Step-by-step explanation:

The general form of quintic-order polynomial is:

$p_{5}(t) = a\cdot x^{5} + b\cdot x^{4} + c\cdot x^{3} + d\cdot x^{2} + e \cdot x + f$

According to the statement of the problem, the polynomial has the following roots:

$p_{5} (t) = (x - r_{1})\cdot (x-3)^{2}\cdot x^{2} \cdot (x+1)$

Then, some algebraic handling is done to expand the polynomial:

$p_{5} (t) = (x - r_{1}) \cdot (x^{3}-6\cdot x^{2}+9\cdot x) \cdot (x+1)\\p_{5} (t) = (x - r_{1}) \cdot (x^{4}-5\cdot x^{3} + 3 \cdot x^{2} + 9 \cdot x)$

$p_{5} (t) = x^{5} - (5+r_{1})\cdot x^{4} + (3 + 5\cdot r_{1})\cdot x^{3} +(9-3\cdot r_{1})\cdot x^{2} - 9 \cdot r_{1}\cdot x$

If $r_{1} = 0$ , then:

$p_{5} (t) = x^{5} - 5\cdot x^{4} + 3\cdot x^{3} +9\cdot x^{2}$

Find the value of x. 4 14 3 6

nadezda [96]

Hello from MrBillDoesMath!

Answer:

Discussion:

As vertical angles are equal, Angle 3 = Angle 2, so

Angle 3 = 3x + 2 (A)

Angles 3 and 7 are corresponding angles and hence equal. So

Angle 3 = Angle 7 => use (A) above and Angle 7 = x + 10

3x + 2 = x + 10 => subtract x from both sides

3x -x + 2 = x - x + 10 =>

2x + 2 = 10 => subtract 2 from both sides

2x = 10 -2 = 8

x = 8/2 = 4

which is the first choice

Thank you,

MrB
