Now, we are looking for a pair of numbers whose product is -16 such as (4,−4), (1, -16), (2, -8). They also have to add up to -6.

The only choice that satisfies both is (2 , -8).

You are watching: What is the factored form of x2 – 6x – 16?

then;

=
*

or

*
=
*

Now taking (x-8) common we get;

=

therefore, the factored form of the

Step-by-step explanation:

The confidence interval for population proportion(p) is given by :-

*

, where

*
= Sample proportion.

n= Sample size.

z* = Critical value.

Let p = Proportion of adults in the U.S. who have donated blood in the past two years.

As per provided , we have

n= 2322

Sample proportion of adults in the U.S. who have donated blood in the past two years. :

*

By z-tmay be , the critical value for 90% confidence : z*= 1.645

Then, the 90% confidence interval for the population proportion of adults in the U.S. who have donated blood in the past two years will be

*

*

*

*

*

Hence, the 90% confidence interval for the population proportion of adults in the U.S. who have donated blood in the past two years. =

2700 years

Step-by-step explanation:

The exponential function for the fraction remaining is ...

r(t) = (1/2)^(t/5730)

where r is the remaining fraction and t is the time in years. We can solve for t to get ...

log(r) = (t/5730)log(1/2)

t = 5730·log(r)/log(1/2)

For the given r=0.72, the age of the artifact is estimated to it is in ...

t = 5730·log(0.72)/log(0.5) ≈ 2700 . . . years
