An online retailer sells two packages of protein bars.
krok68 [10]
In order to find the price per bar, we divide the price by the amount of bars.  For the first one:

15.37/10 = $1.54 per bar

The second package:

15.35/12 = $1.28 per bar.

The 10-pack costs $1.54 per bar and the 12-pack costs $1.28 per bar.  The 12-pack has the better price per bar.

Now, let's look at the price per ounce.  We do this in a similar way.  We find the total amount of ounces in the package, and divide the price by the number of ounces.

In the first package, we multiply 10*2.1=21.  We have 21 ounces in the first package.  Now we divide 15.37/21.  In the first package, we have 0.73 dollars per ounce.

Now, let's look at the second package.  We start by multiplying 1.4*12=16.8.  There are 16.8 ounces in the package.  Now, we divide 15.35/16.8=0.91.  So, in the second package, we have 0.91 dollars per ounce.

The cost per ounce of the 10-pack is $0.73 and the cost per ounce of the 12-pack is $0.91.  The first package has the better price per ounce.

The better explanation is the second one, because I prefer the lower price per ounce, I think that the 1st pack is the better buy.

Answer:

729

Step-by-step explanation:

I have not done this in some time so the terms may be a bit unconventional, but they work. The key to this is multiplying by -3.

1*(-3) = -3

-3*(-3) = 9

And so on.

1, -3, 9, -27, 81, -243, 729

For each of the situations described, state whether the sampling procedure is simple random sampling, stratified random sampling
aleksklad [387]

Answer:

The sampling method applied is Cluster sampling.

Step-by-step explanation:

A cluster sampling method is the type of sampling where first the entire population is divided into homogeneous groups. Then a random sample of these groups are selected.

After selecting a sample of groups, a random sample of fixed size is selected from each group.

In this case all freshmen are first divided into 30 sections, then 4 random sections are selected and the students in those 4 sections are sampled.

The sampling method applied is Cluster sampling.

A business organization needs to make up a 7 member fund-raising committee. The organization has 6 accounting majors and 7 finan
photoshop1234 [79]

Answer: 658 ways.

Step-by-step explanation:

To find the number of ways the number "r" items can be chosen from the available number "n", the combination formula for selection is used. This formula is denoted as:

nCr = n! / (n-r)! × r!

Where n! = n×(n-1)×(n-2) ... ×3×2×1.

If we have 6 accounting majors and 7 finance majors and we are to choose a 7-member committee from these with at least 4 accounting majors on the committee, then the possibilities we have include:

[4 accounting majors and 3 finance majors] Or [5 accounting majors and 2 finance majors] or [ 6 accounting majors and 1 finance major].

Mathematically, this becomes:

[6C4 × 7C3] + [6C5 × 7C2] + [6C6×7C1]

525 + 126 + 7 = 658 ways.

Note: it is 6C4 because we are choosing 4 accounting majors from possible 6. This applies to other selection possibilities.
