Answer:
1) 1/6, 1/3, 1/2, 3/4
2) 3/10, 2/5, 7/10, 4/5
3) 1/4. 7/12. 2/3, 5/6
4) 4/15. 11/30, 2/5, 7/10
Step-by-step explanation: Either convert all in a set to a common denominator, or convert to decimal fractions.
<h3>a. slope =

Scatter plot shows the relationship between data
We can use Regression to make lines on the chart or you can also make lines with the principle as close as possible to all points
Regression
Because data is in the form of numbers from the hand span length and height of each of students. not displayed clearly, then we make a line directly by making points on the graph above and below the line as much as possible to be balanced
We specify 2 points that are crossed by a line, for example:
(6.45) and (8.60)
slope (m) = change in y / change in x
Slope has a positive value, and shows a positive correlation where the tendency of the number rises simultaneously, or can be concluded:
<em>tall students will have the long hand span length too</em>

Answer:
About 3.6 times greater.
Step-by-step explanation:
That is 1.793 * 10^8 / 5.01 * 10^7
= 1.793 / 5.01 * 10^(8-7)
= 0.36 * 10
= 3.6
Alright, lets get started.
Please refer the attached diagram.
The roof will make a right angle triangle.
Thy hypotenuse of the triangle will be the length of roof that is given 44 feet.
The opposite side will be height of roof that is 10 feet.
Lets suppose roof makes x degree angle from horizontal.
So, we know,
sin x = opposite / hypotenuse
sin x = 10 / 44
sin x = 0.2272727272
Taking inverse on both sides
sin -1 (sin x) = sin -1 (0.2272727272)
x = sin -1 (0.2272727272)
x = 13.13 degrees
So the angle that roof makes with horizontal is 13.1 degrees (option b) : Answer
