<u>2. What is P(M), the probability that a student plans to major in mathematics?</u>
- P(M) = number of students who plan to major in mathematics / number of students
Answer: 
Step-by-step explanation:
Claim : A a political strategist wants to test the claim that the percentage of residents who favor construction is more than 53%.
Let 'p' be the percentage of residents who favor construction .
Claim : 
We know that the null hypothesis has equal sign.
Therefore , the null hypothesis for the given situation will be opposite to the given claim will be :-
And the alternative hypothesis must be :-
Thus, the null hypothesis and the alternative hypothesis for this test :
800x87979 es 70, 383, 200

The new equation will be (x-1)² + (y-18)²=36
2) x²+y²+6x+12y=4
(x²+6x+?)-(?) + (y²+12y +??) -(??)=4
(x²+6x+9)-(9) + (y²+12y +36) -(36)=4
(x+3)² - 9 + (y+6)² - 36 = 4
(x+3)² +(y+6)² = 49
