The equivalent expression is option A) 12(l+2a)
<u>Step-by-step explanation</u>:
- The expression for total cost = 12l+24a
- Taking 12 as common from all the terms in the expression,
we get, 12 (l+2a)
Therefore, The equivalent expression of 12l+24a is 12(l+2a).
Answer:
a) 
And replacing we got:

b) 
And using the normal standard distribution table and the complement rule we got:

Step-by-step explanation:
From the info given if we define the random variable X as "amount of saturated fat in a daily serving of a particular brand of breakfast cereal " we know that the distribution of X is given by:

Part a
For this case the sample size would be n =30 and then the distribution for the sample mean would be given by:

And replacing we got:

Part b
We want to find this probability:

And we can use the z score formula given by:

And replacing we got:

And using the normal standard distribution table and the complement rule we got:
