50 envolopes for 2.49 or 90 for 5 .50

Elza [17]

Answer:

The better deal would be to buy the 50 envelopes for a total of $2.49

Step-by-step explanation:

Identify what you know:

1) You can buy a pack of 50 envelopes for $2.49

2) You can buy 90 envelopes for $5.50

Divide the number of enveloped by the prices, to find the price of ONE envelope in the pack. See:

$2.49/50 envelopes = $0.0498

$5.50/90 envelopes = $0.061

Also... where is THIS person buying envelopes... I want that price....

Answer with explanation:

$\text{Average}=\frac{\text{Sum of all the observation}}{\text{Total number of Observation}}$

Average Height of tallest Building in San Francisco

$=\frac{260+237+212+197+184+183+183+175+174+173}{10}\\\\=\frac{1978}{10}\\\\=197.8$

Average Height of tallest Building in Los Angeles

$=\frac{310+262+229+228+224+221+220+219+213+213}{10}\\\\=\frac{2339}{10}\\\\=233.9$

→→Difference between Height of tallest Building in Los Angeles and Height of tallest Building in San Francisco

=233.9-197.8

=36.1

⇒The average height of the 10 tallest buildings in Los Angeles is 36.1 more than the average height of the tallest buildings in San Francisco.

⇒Part B

Mean absolute deviation for the 10 tallest buildings in San Francisco

|260-197.8|=62.2

|237-197.8|=39.2

|212-197.8|=14.2

|197 -197.8|= 0.8

|184 -197.8|=13.8

|183-197.8|=14.8

|183-197.8|= 14.8

|175-197.8|=22.8

|174-197.8|=23.8

|173 -197.8|=24.8

Average of these numbers

$=\frac{62.2+39.2+14.2+0.8+13.8+14.8+14.8+22.8+23.8+24.8}{10}\\\\=\frac{231.2}{10}\\\\=23.12$

Mean absolute deviation=23.12

Helpppp please can somebody please explain this to me.

Answer:

this is simple once you get the hang of it!! as you see in the chart they gave you, 1=3.15, meaning you graph it (1, 3.15) and so on. all you do is multiply each number (for example, 4) times 3.15 and (4x3.15=6). so 3.15 times all the x-axis numbers and graph it (x, y).. hope this makes sense :)
