Answer:
he is on 4 he is 4 away from the zero
he will land on -2 he is 2 away from 2
he will land on 5
-2 because -2 plus 2 is 0
-4, -4 absolute value is 4 so it's -4 (its original placing)
Answer:
20.6
Step-by-step explanation:
23.6-2x3/2
Solve:
23.6-2x3/2
=23.6 - 6/2
= (47.2-6)/2
=20.6
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:
g(x+2) means that x + 2 is going into g(x).
Step-by-step explanation:
Given:
g(x) = x^2 - x
g(x + 2)
g(x+2) means that x + 2 is going into g(x)
x = x + 2
Substitute:
g(x + 2) = (x + 2)^2 - (x + 2)
Solve:
g(x + 2) = (x + 2)^2 - (x + 2)
= x^2 + 4x + 4 - (x + 2)
= x^2 + 4x + 4 - x - 2
Simplify:
g(x + 2) = x^2 + 3x + 2
It works out that: y = 1 or 5 and therefore x = 5 or 1
