Michael is making cookies. Each batch uses 2 cups of flour. He plans to use less than 30 cups of flour so that he has enough lef

Elan Coil [88]

Your answer is A. Michael can make fewer than 13 batches of cookies

If he has 30 cups of flour and has already used 4, subtract.
=26
so he has 26 cups of flour and it takes two cups to each batch, so divide.
26/2=13
if the two batches he has already made are included in the problem, then your answer would actually be C. but I don't think that's the case.

scoray [572]

Answer:

The minimize size that can be taken is - 31.28 or 31 .

Step-by-step explanation:

Lets calculate -

Population standard deviation, $\sigma=3.4 inches$

Margin of error, E = 1

Critical value , $z_0_._0_5 =1.645$

Now , the size of the sample , $n=(\frac{z\times \sigma}{E} )^2$

Putting the given values ,

$=(\frac{1.645\times 3.4}{1})^2$

= 31.28 or 31 .

The given table of the question has been attached here .

<u>Hence , the answer is 31.</u>
