Answer:
Result is statistically significant.
Step-by-step explanation:
Given that :
Chisquare statistic, χ² = 67.81
Critical value for the distribution, χ²critical = 3.84
α = 0.05
The Decison region :
If χ² statistic > Critical value ; Reject H0 ; this. Eans that result is statistically significant.
Therefore, since, 67.81 > 3.84 ; This means that the result is statistically significant at 0.05
An equation is formed of two equal expressions. The correct option is x+y=557 and Three-fifths(x)+five-sixths(y)=407.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the total number of pages in the shorter book be represented by x, and the total number of pages in the longer book be represented by y.
Given the total number of pages of the shorter book and the longer book is 557. Therefore, the equation can be written as,
x+y =557
Also, Scott reads Three-fifths of the shorter book and StartFraction 5 Over 6 EndFraction of the longer book, which is equal to 407 pages. Therefore,
(3/5)x + (5/6)y = 407
Hence, the correct option is x+y=557 and Three-fifths(x)+five-sixths(y)=407.

Step-by-step explanation:
Answer:
See below ↓
Step-by-step explanation:
The relation is :
- Let y = Motor Speed and x = Voltage
- y = 25x
<u>Title</u> : Variation of Motor Speed with Applied Voltage
<u>x-axis label</u> : Voltage (volt)
<u>y-axis label</u> : Motor speed (rpm)
As it constantly varies with a value of x and they are not isolated data points, they should be connected with a line.
The answer is:19.52.
Hopefully this has helped! :)
