The answers are...
Question 1: b.) 12
Question 2: c.) 51
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
You have to do the diamond method
Example
X^2-5x+6
a×c
b
6
-2 -3
-5
Answer:
b = -2
Step-by-step explanation:
Given expression:
9(b - 4) - 7b = 5(3b -2)
Using distributive properties, open the parentheses;
9b - 36 - 7b = 15b - 10
2b - 36 = 15b -10
collect like terms;
2b - 15b = - 10 + 36
-13b = 26
Divide both sides by -13;
b = -2
The area of a triangle is A= 1/2bh. Plugging in the values you know, 30= 1/2*12*h.
Solving for h,
30= 1/2*12*h
30= 6h
h=5
The height of the triangle is 5 units.
