Correct answer only !

the weights of bags of ready-to-eat salad are normally distributed with a mean of 290 grams and a standard deviation of 10 grams.

what percent of the bags weigh less than 280 grams?

 b) 16%

Step-by-step explanation:

The mean is 290 so on a normal bell curve that would be a z-score of 0.

The standard deviation is 10 so 290 - 10 = 280 is a z-score of -1.

A z-score from the left to -1 is 15.9%

f(x)=3x+2,g(x)=2x^(2)-1

Step-by-step explanation:

First set up the composite result :

f (g (x))

Evaluate f (g (x))

3( 2x sqaured -1 ) + 2

Simplify:

f ( 2X SQUARED -1 ) 6 x squared -3 + 2

Add 2 and -3
