Select two polynomials that have a sum of 16n^3+13n^2+7n-10 A. 8n^3 - 5n +11n^2 - 5 B. 7n^2 + 8n - n^3 + 2 C. 15n^2 - 10n + 3n^3
andreyandreev [35.5K]

Answer:

Step-by-step explanation:

We have the polynomial

16n^3+13n^2+7n-10   ( 1 )

To solve this problem we have to take into account that only we can sum term with the same order in the variable. We have the polynomials

8n_{3}-5n+11n^{2}-5\\7n^2 + 8n - n^3 + 2\\15n^2 - 10n + 3n^3 - 4\\2n^2 + 12n - 5 + 8n^3

we can note (by summing term by term) that only the sum of the first and the fourth equation correspond to the given polynomial ( 1 ) of the problem. If we organize these polynomials (that is, write the equation down in a form where higher order appears first ) we have

8n^3 +11n^2 - 5n  - 5\\ 8n^3+2n^2 + 12n - 5\\

and if we sum we obtain

16n^3+13n^2+7n-10

that is what we was looking for

I hope this is useful for you

A car insurance company has determined that 8% of all drivers were involved in a car accident last year. If 14 drivers are rando
OLga [1]

Answer:

0.0958

Step-by-step explanation:

Percentage involved in accident = 8% = 0.08

Number of drives selected = 14

Probability that 3 or more who were involved in a car accident last year?

P(x>=3) = P(x=3) or P(x>3)

Similarly;

P(x>=3) = 1-P(0<= x <=2)

P(x>=3) = 1-P(0<= x <=2)

Using the binomial probability calculator :

Cummulative probability :

P(X >= x) = 0.09583481948

= 0.0958
