4n2 - 3 = 61<br>how do I solve by square roots​
NeX [460]

Answer:

n = 4 or n = -4

Step-by-step explanation:

We have: 4n² - 3 = 61.

Add 3 to both sides:

4n² = 61 + 3 = 64

Divide both sides by 4:

n² = 64/4 = 16

Square root both sides:

n = +/- √16

n = 4 or n = -4

The answers are 4 and -4.

Suppose we are interested in bidding on a piece of land and we know one other bidder is interested. The seller announced that th
Alik [6]

Answer:

P(X

And for this case we can use the cumulative distribution function given by:

P(X\leq x) =\frac{x-a}{b-a}, a \leq x \leq b

And using this formula we have this:

P(X

Then we can conclude that the probability that your bid will be accepted would be 0.41

Step-by-step explanation:

Let X the random variable of interest "the bid offered" and we know that the distribution for this random variable is given by:

X \sim Unif( a= 10100, b =14700)

If your offer is accepted is because your bid is higher than the others. And we want to find the following probability:

P(X

And for this case we can use the cumulative distribution function given by:

P(X\leq x) =\frac{x-a}{b-a}, a \leq x \leq b

And using this formula we have this:

P(X

Then we can conclude that the probability that your bid will be accepted would be 0.41
