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?
Now taking (x-8) common we get;
therefore, the factored form of the
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
The confidence interval for population proportion(p) is given by :-
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
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. =
