at a delicatessen, ham costs $2.49 per pound and swiss cheese costs $3.79 per pound. The customer has $9.50 to spend on 2 pounds
vichka [17]

The customer can purchase 1.19788 pounds of cheese (approximately 1.2 pounds).

<h3>How much cheese can she purchase?</h3>

We are given with the cost of ham is $2.49 per pound and

Cost of swiss cheese is $3.79 per pound.

So, the cost of 2 pounds of ham will be given as-

= 2× $2.49

= $4.98

Since, the customer has a total of  $9.50 to spend on 2 pounds of ham and some cheese,

∴ Let the number of pounds of cheese she can purchase be x.

Then the equation will be this:

2.49*2 + 3.79*x = 9.50

4.98 + 3.79x = 9.50

Subtracting 4.98 from each side we get-

4.98 -4.98 + 3.79x = 9.50-4.98

3.79x = 4.54

x  =\frac{4.54}{3.79}

x = 1.19788 pounds of cheese (approximately 1.2 pounds).

Hence, the customer can purchase 1.19788 pounds of cheese (approximately 1.2 pounds).

What is the difference between the mean and the median of the data set?
natka813 [3]

Answer:

Your answer is 0 (zero).

<u>Step</u><u> </u><u>by</u><u> </u><u>Step</u><u> </u><u>Explanations</u><u>:</u>

<u>For</u><u> </u><u>mean</u><u>:</u>

1. Add all the numbers; which is 90

2. Divide by how numbers there are, for this case there are 6 numbers; 90/6 = 15

3. Your mean is 15

For Median:

1. Order the numbers from lest to greatest. Ex: 8, 10, 12, 18, 20, 22

2. Find the middle number(s), which are 12 &18

3. Add; 12 + 18 = 30

4. Divide; 30/2 =15

5. Your Median is 15

So now the question asks "what's the difference?" which means subtraction: 15 - 15 = 0

Anon25 [30]

The error interval for x is 3.65,3.74.

Given that,

  • The number rounded to one decimal place is 3.7.

Now based on the above information, the number should be more than or equivalent to 5 at the n+1 place

  • Like 3.65, 3.66, 3.67, 3.68 till 3.74

Based on the above information, we can conclude that the error interval for x is 3.65,3.74.
