Answer:
36/5
Step-by-step explanation:
x/3 + 6 -2x = -6
multiply the whole equation by 3 to get rid of the denominator of the first x term.
x+18-6x = -18
move x terms to one side and numerical terms to the other, subtract 18 from both sides in this case
x+18-6x-18=-18-18
x-6x = -36
simplify
-5x = -36
divide both sides by -5 to isolate x
x = -36/-5
=36/5
Answer:
−22.599a−32.513
Step-by-step explanation:
Distribute:
= (4.1) (−7.93) + (4.1) (− 4.39 a) + − 4.6 a
= − 32.513 + − 17.999 a + − 4.6 a
Combine Like Terms:
= −32.513 + − 17.999 a + − 4.6 a
= (− 17.999 a + −4.6 a) + (− 32.513)
= − 22.599 a + (− 32.513) = − 22.599 a − 32.513
Answer: 0.0336
Step-by-step explanation:
Given : The distribution of cholesterol levels in teenage boys is approximately normal with mean :
Standard deviation : 
The formula for z-score is given by :-

For x=225

The p-value =

The probability that a teenage boy has a cholesterol level greater than 225 =0.0336
