What are the two solutions of 2x^2=-x^2-5x-1

hammer [34]

Answer:

x = 5/-6 + (√13)/-6

x = 5/-6 -(√13)/-6

Step-by-step explanation:

2x^2 = -x^2 - 5x - 1. Subtract 2x^2 from both sides.

-3x^2 - 5x - 1. Do the quadratic formula.

That gives you:

-5/6 ± (√13)/-6.

Simple random sampling uses a sample of size n from a population of size N to obtain data that can be used to make inferences ab

OLEGan [10]

Answer: 6,77,040 different random samples of four accounts are possible.

Step-by-step explanation:

We have to calculate the different random samples of four accounts are possible from the population of 65 bank accounts.

we are using combination formula for calculating various combination of four accounts:

= $^{n}C_{r}$

Where,

n - total population of bank accounts

r - random samples drawn from the population

= $^{65}C_{4}$

= $\frac{n!}{r!(n-r)!}$

= $\frac{65!}{4!(65-4)!}$

= $\frac{65!}{4!(61)!}$

= 6,77,040 different random samples of four accounts are possible.
