Answer:
the distance is 9.1 inches (please give brainliest)
Step-by-step explanation:
we must use the pythagorean theorem:
5.7^2 + 7.1^2 = c^2
(c being the distance being the two corners)
c^2 = 82.9
c = sqrt(82.9) ≈ 9.1
Answer:
(A) Scatterplot
Step-by-step explanation:
The most helpful visualization to spot outliers would be a scatterplot.
When collecting data on a scatterplot, you can see how the results are similar and which areas have the most answers and such.
There can be multiply outliers on a scatterplot, and they stand out because while most answers will be clumped together, the outliers will not.
Trapezoidal is involving averageing the heights
the 4 intervals are
[0,4] and [4,7.2] and [7.2,8.6] and [8.6,9]
the area of each trapezoid is (v(t1)+v(t2))/2 times width
for the first interval
the average between 0 and 0.4 is 0.2
the width is 4
4(0.2)=0.8
2nd
average between 0.4 and 1 is 0.7
width is 3.2
3.2 times 0.7=2.24
3rd
average betwen 1.0 and 1.5 is 1.25
width is 1.4
1.4 times 1.25=1.75
4th
average betwen 1.5 and 2 is 1.75
width is 0.4
0.4 times 1.74=0.7
add them all up
0.8+2.24+1.75+0.7=5.49
5.49
t=time
v(t)=speed
so the area under the curve is distance
covered 5.49 meters
<h2><u>Problem Solving</u>:-</h2>
2. The table below shows that the distance d varies directly as the time t. Find the constant of variation and the equation which describes the relation.
<h2><u>Solution</u>:-</h2>
Since the distance d varies directly as the time t, then d = kt.
Using one of the pairs of values, (2, 20), from the table, substitute the values of d and t in d = kt and solve for k.
<h2><u>Answer</u>:-</h2>
- Therefore, the constant of variation is 10.
