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 is; A Gallup survey of 2322 adults (at least 18 years old) in the U.S. found that 408 of them have donated blood in the past two yea

mslsec.com: 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. = 5 0

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
