An elephant drinks 49 gallons of water per day. A rhinoceros drinks 21 gallons of water per day. What is the total amount of water the animals will drink in 8 days?

Given:

An elephant drinks 49 gallons of water per day.

A rhinoceros drinks 21 gallons of water per day.

To find:

The total amount of water the animals will drink in 8 days.

Solution:

In each day,

Elephant drinks = 49 gallons

Rhinoceros drinks = 21 gallons

Total amount of water they will drink each day is

They will drink 70 gallons in each days.

So, total amount of water the animals will drink in 8 days is

Therefore, they will drink 560 gallons of water in 8 days.

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33

the answer for this question is a= 13,622.84
