Just draw a rectangle, cut it into 3 horizontal lines, and cut it into 4 vertical lines.
This is simple pythagoras, its just a²+b²=c². First you find the hypotenuse, which is 97; now you have the equation: x²+72²=97²
x²=9409-5184
x= √4225
x=65
the answer is 65m
Answer:
Step-by-step explanation:
At time zero the level was 7 gallons and at time 3 min, the level was 5 gallons.
<u>Take two points:</u>
<u>Find the rate of change:</u>
This is a 2 gallons per 3 minutes
<u>Tank holds 10 gallons, it was emptied by 3 gallons and it took:</u>
- 3 : (2/3) = 3* 3/2 = 4.5 minutes
<u>Answer-</u>
<em>About </em><em>4 points</em><em> should be below the trend line.</em>
<u>Solution-</u>
A Scatter Plot has points that shows the relationship between two sets of data.
A line of best fit or trend line is a straight line that best represents the data on a scatter plot.
This line may pass through some of the points, none of the points, or all of the points.
But its objective is to have the line as close as possible to all points, and as many points above the line as below.
As there are 4 points above the trend line, so there should be 4 points below that.
