John has 6 puppies for sale and wants to advertise them in the cleveland plain dealer. to advertise in the paper there is a flat or fixed rate for the first then words of the ad and a fixed charge for each additional word. the cost of a 17-word ad is $14.55. the cost for a 21-word ad is $17.15. what is the flag rate for the first 10 words and the fixed charge for each additional word?

Fixed cost of first ten words is $10. For every additional word in the advertisement, the cost is $0.65 per word.

Step-by-step explanation:

Let the fixed rate for first 10 words be x

Let the charge for each additional word be y.

Formulating the equations as per the problem:

\[x + 7y = 14.55\]   (1)

\[x + 11y = 17.15\]   (2)

Subtracting the two equations:

\[11y - 7y = 17.15 - 14.55\]

=> \[4y = 2.60\]

=> \[y = 0.65\]

Substituting in equation (1),

\[x + 7 * 0.65 = 14.55]\

=> \[x = 14.55 - 7 * 0.65 = 14.55 - 4.55 = 10\]

Hence the fixed cost of first ten words is $10

For every additional word in the advertisement, the cost is $0.65 per word.

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

i am only able to answer the first part. i am not sure about the second part. sorry

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
