harina [27]

Answer:

289/290

Step-by-step explanation:

Given that the chance of Donnell being selected is 1/290

then P( Donnell being selected )= 1/290

Since Donnell and Maria are both member of a population.

from probability theorem which gives the likely hood of an event to happen which cannot be more than 1, then the probability of Donnell and Maria to be selected is 1

P(Donnell and Maria)= 1

But the chance of Donnell being selected is 1/290

Then,

1/290 + P(Maria)= 1

P(Maria)= 1-(1/290)

= 289/290

the chance of Maria being selected is 289/290

i believe that it’s a but i don’t want to get it wrong can someone help me (no wrong answers pleaseee)
VARVARA [1.3K]

Answer:

B

Step-by-step explanation:

For the divisor on the left of the division symbol, the -3 symbolizes that the -3 is a root. This means that when we plug -3 into our divisor, the answer is 0. Therefore, as x+3=0 when x=-3, the divisor is x+3.

Next, for the dividend, we can start on the left with no x multiplied to it and then add one degree of x for each value to the left. This results in

6 + -4 * x¹ + 4 * x² + 2 *x³

= 2x³ +4x² -4x+6
