Answer:
Step-by-step explanation:
The distance, D, is given by the speed, S, times the time, T:
D = S*T
<u> D </u> <u> S*T </u> <u> Time </u> <u>Equation for each segment</u>
200 = 150T1 T1 = 1.33 hr y=150x 0 T 1.33 hr
300 = 200T2 T2 = 1.5 hr y=200x 1.33 T 2.83 hr
400 = 250T3 T3 = 1.6 hr y=400x 2.83 T 4.43 hr
The graph can be drawn as three lines, ione each for the three segments, each having the slope shown in the equation for that segment and extending between the range of values for T (which is the "x" in the equation and on the graph). The y axis will be ditance, in km.
The overall speed is the total distance divided by the total time:
D(km) T(hr)
1) 200 1.33
2) 300 2.83-1.33 = 1.5
3) <u>400</u> <u>4.43-2.83 = 1.6</u>
900 km 4.43 hr
(900 km)/(4.43 hr)
Average speed = 203.01 km/hr

K is the number of groups in one way ANOVA. Since here 4 groups involved. So k here is four.
<u>Explanation:</u>
In statistics, one-way analysis of variance is a technique that can be used to compare means of two or more samples. This technique can be used only for numerical response data, the "Y", usually one variable, and numerical or categorical input data, the "X", always one variable, hence "one-way".
The one-way analysis of variance (ANOVA) is used to determine whether there are any statistically significant differences between the means of two or more independent (unrelated) groups (although you tend to only see it used when there are a minimum of three, rather than two groups).

According to the statement of the question, we conclude that the area of a square is requested, whose value is 171 in²
The area of a square is given by the expression:
A = S²
<em>where S is the side of the square - just what we want to know</em>
So:
A = S²
171 = S²
√171 = S
<h3>S ≈ 13.08in</h3>
