Answer with Step-by-step explanation:

Mean=sum of all observations/number of observations

Median=middle term of all observations arranged in ascending order

Mode=observation with highest frequency(the observation which is repeated so many times)

Range=largest observation subtracted by the smallest

7)    14, 7, 34, 29, 14, 6

multiply by 6

84,42,204,174,84,36

Arranging in ascending order

36,42,84,84,174,204

Mean=104

Median=84

Mode=84

Range=168

8)   13, 17, 15, 18, 21, 13, 20

add 3.7

16.7,20.7,18.7,21.7,24.7,16.7,23.7

arranging in ascending order

16.7,16.7,18.7,20.7,21.7,23.7,24.7

Mean=20.41

Median=20.7

Mode=16.7

Range=8

If 4 gal of premium unleaded gasoline costs $15.04, how much would it cost to completely fill a tank whose capacity is 9-gal?
Sveta_85 [38]

Answer:

$33.84 cents

Step-by-step explanation:

Given the following question:

4 gallons = 15.04
1 gallon = ?

How much for 9 gallons?

To find the answer we have to find how much one-gallon costs since we already know how much it costs for 4 gallons of this unleaded gasoline.

15.04\div4
15.04\div4=3.76
=3.76

One gallon of this gasoline costs $3.76 now we need to find how much it costs for 9 gallons.

3.76\times9=33.84
=33.84

For nine gallons of gasoline it will cost you "$33.84 cents."

Hope this helps.

1) Order the animals by sleep time from least to greatest.
Zolol [24]
The way to line the animals is to put them in order going down. 0.433 56.3% 19/40 65.8%. Then you try to figure out what you need to convert so that you can get your answer. 56.3% changes to 0.563 because you move the decimal two places to the left. 65.8% changes to 0.658 and 19/40 is 0.475. 0.433 0.563 0.475 0.658. Now you compare each row to figure them out. When you do that your answer will be 0.433, 0.475, 0.563, and 0.658. I sleep about 9/24 of the day which is 0.375 and I will fit right befor 0.433.
