Answer:
-Accept
-There is no sufficient evidence to back the claim that the proportion of American adults who oppose reinstatement of the draft is greater than 0.7
Step-by-step explanation:
-We state our hypotheses as:
#We the calculate the proportion to be studied using the formula:
-The z-value from this proportion is calculated as follows:
#We compare this z-value to the z-value at 95% confidence level:
Hence, Accept the null hypothesis.
-There is no sufficient evidence to back the claim that the proportion of American adults who oppose reinstatement of the draft is greater than 0.7

Answer:
Step-by-step explanation:
USE FOIL method
(x +6)(x + 2) = x*x + x*2 +6*x +2*6
=x² + 2x + 6x + 12 {Combine like terms}
= x² + 8x + 12
(x+ 7)(x + 2) = x*x+ x*2 +7*x + 7*2
= x² +2x+ 7x + 14
= x² + 9x + 14
(x+1)*(x +7) = x*x + x *7 + 1*x + 1*7
=x² + 7x +x + 7
=x² + 8x + 7
Cross multiply,
5*(3x+1) = x² + 9x + 14
5*3x + 5*1 = x² + 9x + 14
15x + 5 = x² + 9x + 14
x² + 9x + 14 - 5x - 5 = 0
x² + 9x - 5x + 14 - 5 = 0
Combine like terms
x² + 4x + 9 = 0
a = 1 ; b = 4 ; c = 9
D = b² - 4ac
= 4² - 4*1*9
= 16 - 36
= -20
= 20i² {i² = -1}
√D = √20i² =
