Step-by-step explanation:sure answer:
X-17=21
X=21+17(when we transpose -ve becomes positive)
X=38
Answer:
The 95% confidence interval for the population proportion of adults in the country who believe that televisions are a luxury they could do without is (0.500, 0.562).
Step-by-step explanation:
The complete question is:
A random sample of 1014 adults in a certain large country was asked "Do you pretty much think televisions are a necessity or a luxury you could do without?" Of the 1014 adults surveyed, 538 indicated that televisions are a luxury they could do without.Construct and interpret a 95% confidence interval for the population proportion of adults in the country who believe that televisions are a luxury they could do without.
Solution:
In a sample of 1014 adults, 538 indicated that televisions are a luxury they could do without.
Compute the sample proportion of adults who indicated that televisions are a luxury they could do without as follows:
The (1 - <em>α</em>)% confidence interval for population proportion is:
The critical value of <em>z</em> for 95% confidence interval is:
*use a <em>z</em>-table.
Compute the 95% confidence interval for the population proportion of adults in the country who believe that televisions are a luxury they could do without as follows:
Thus, the 95% confidence interval for the population proportion of adults in the country who believe that televisions are a luxury they could do without is (0.500, 0.562).
Answer:
Yes
Step-by-step explanation:
3.212 x 10^4
=> 3.212 x 10000
=> 32.12 x 1000
=> 321.2 x 100
=> 3212 x 10
=> 32120 x 1
=> 32120
So your question was not very clear but with (f+g) im guessing thats f(x)+g(x)
So first we add them x^2+4x-32 + x-4 then we will get x^2 + 5x - 36
Then we need to multiply both
(x^2+5x-36)(x^2+5x-36)
=
(x^2+5x-36)^2
The only reason im not solving it out is because it yields large numbers and you might not understand.
