Answer:
x = -1.2
Step-by-step explanation:
Th given equation is :
34(x + 4) = 14(x + 8)
Step (A) Distribute 34 on the left side of the equation such as :
34x + 34(4) = 14(x + 8)
34x + 136 = 14(x + 8)
Step (B) Distribute 14 on the right side of the equation such as :
34x + 136 = 14x + 14(8)
34x + 136 = 14x + 112
Step (C) Subtract 14x from each side of the equation.
34x + 136 - 14x = 14x + 112 -14x
20x + 136 = 112
Step (D) Subtract 136 from each side of the equation.
20x + 136 -136 = 112 -136
20x = -24
Step (E) Divide both side by 20
So, the value of x is (-1.2). Hence, steps (D) and (E) are incorrect.

Answer:
H0: p1=p2 against the claim Ha: p1≠p2
Step-by-step explanation:
Here the proportion of the people going for medical checkup before the program is p1= 0.76
The proportion of the people going for medical checkup after the program is p2= 686/880=0.78
Our null and alternate hypothesis will be
H0: proportion of the people going for medical checkup before the program <u>is equal </u>to the proportion of the people going for medical checkup after the program
against the claim
Ha: proportion of the people going for medical checkup before the program <u>is not equal </u>to the proportion of the people going for medical checkup after the program
Mathematically this can be written as
H0: p1=p2 against the claim Ha: p1≠p2
