Answer:

Step-by-step explanation:

We know that z=\frac{x-{\mu}}{\sigma}            (1)

and also we are given that a person is obese if the z-score of his or her weight is greater than 2.

Thus, using this information we can rewrite the above equation (1),

2\geq\frac{x-160.4}{27}

Solving this equation, we have

⇒54\geq(x-160.4)

⇒54+160.4\geq x

⇒214.4\geq x

Thus,  the obesity threshold weight for a young adult American male is 214.4lb\geq x.

Identify the angle relationship, write an equation and Solve for x. ​
irakobra [83]

Answer:

2x-6+x+x=180

4x-6=180

4x=180+6

4x=186

x=\frac{186}{4}=46,5°

Step-by-step explanation: the other angle is equal to his simmetrical, cause the triangle is isosceles, so is value is x. The sum of the angle in a triangle must be 180°
