Both are supplementary angles so their sum will be 180°
Answer:
No solution
Step-by-step explanation:
Assume x - 4 ≠ 0 and x + 5 ≠ 0,
note (x - 4)(x + 5) = x² + x - 20, so x² + x - 20 ≠ 0
Multiply by (x - 4)(x + 5) both sides and
get
x(x + 5) - 4(x - 4) = 36
x² + 5x - 4x + 16 = 36
x² + x - 20 = 0
But we have assumed x² + x - 20 ≠ 0
So the equation has no solution
Answer:
The 95% confidence interval for the proportion of adolescents who tried smoking for the first time because of exposure to smoking in the movies is (0.37, 0.40).
Step-by-step explanation:
A confidence interval is an interval estimate of the population parameter. The confidence interval has a certain probability of consisting the true value of the parameter.
The (1 - <em>α</em>) % confidence interval for the population proportion (<em>p</em>) is given by:
The information provided is:
*Use a <em>z</em>-table for the critical value.
Construct the 95% confidence interval for the proportion of adolescents who tried smoking for the first time because of exposure to smoking in the movies as follows:
Thus, the 95% confidence interval for the proportion of adolescents who tried smoking for the first time because of exposure to smoking in the movies is (0.37, 0.40).
