1. (a) Show that the polynomial x⁴+ 4x³ + 6x² - 8 is divisible by x+2

Tpy6a [65]

Answer:

Step-by-step explanation:

if x= -2

and P(x)=x^4+4x^3+6x^2-8

then P(-2)=(-2)^4+4*(-2)^3+6*(-2)^2-8=16-32+24-8=0

so P(x)=(x+2)* Q(x) and P(x) is divisible by x+2

Macy is playing with a standard deck of fifty-two playing cards. She selects one card at random from the deck. What is the proba

olasank [31]

Answer:

The probability that the card is an ace is $\frac{1}{13}$

Step-by-step explanation:

Total number of playing cards = 52

Total number of ace cards = 4

She selects one card at random from the deck.

We are supposed to find the probability that the card is an ace

So, Probability of getting card= $\frac{\text{No. of ace cards}}{\text{Total no. of cards}}$

Probability of getting card= $\frac{4}{52}=\frac{1}{13}$

Hence the probability that the card is an ace is $\frac{1}{13}$
