Answer:
(a)z=-1
(b)48.5 pounds
(c)61.5 pounds
Step-by-step explanation:
Given:
Mean, μ = 55 pounds
Standard deviation,σ = 6 pounds.
(a)For a dog that weighs 49 pounds.
x=49 pounds
The z-score
(b)When a dog has a z-score of -1.09
The weight of a dog with a z-score of -1.09 is 48.5 pounds.
(c)When a dog has a z-score of 1.09
The weight of a dog with a z-score of 1.09 is 61.5 pounds.

Answer: X < 0.25.
Step-by-step explanation:
1. The absolute value of 2 - 4x would be the same as 2 + 4x.
2. Multiply 2 by 1/4. 1/4 of 2 would be 0.5
3. 5/2 is the same as 2.5.
4. Move the variables to one side and the numbers to the other side. In this case, move 0.5 to the opposite side of the <, making it -0.5. The right side of this problem should be 2.5 - 0.5. Do the same with move -2x to the other side, making it +2x. 4x + 2x is 6x.
5. The problem should now be 6x < 1.5. Divide each side by 6.
6. x < 0.25
Mid point = ( 1/2 the sum of x coordinates) , ( 1/2 sum of y coordinates)
= (-42+28)/2 . ( -53 - 19) / 2
= ( -7, -36) Answer
