Answer:
Angle x = angle 115°.
Step-by-step explanation:
Given : Two parallel lines are crossed by a transversal.
To find : What is the value of x.
Solution : We have given Two parallel lines are crossed by a transversal.
Corresponding angles : A pair of angle that lies on the same side of the transversal line one lies on interior angle and other lies on exterior.
Corresponding angle are equal.
Then , angle x = angle 115 are corresponding.
Therefore, angle x = angle 115.

Answer:
a) median= 25 mins
interquartile range= 19mins
b) the braineys
, because the braineys took 32mins on average and the cleverites took 25 mins on average which is 7 minutes more.
Step-by-step explanation:
a) find the median by going across the middle of the cumulative frequency (in this case, 40) until it hits the line (the cleverites) and move down to see the time in minutes. 25 mins.
to find the interquartile range, first find the lower quartile. So find the half of the median, or the quarter of the cumulative frequency ( 20) and go across until it hits the line and look down from that point to find the time ( 15 mins). Then, find the upper quartile by finding 3/4 or half+quarter of the cumulative frequency (60) and do the same with the line (34mins)
the interquartile is upper quartile - lower quartile
34-15= 19 mins
interquartile= 19 mins.
b) the average is the same as the median, so find the median for the cleverites and the median for the braineys, which is 25 mins and 32 mins, therefore the braineys took longer, thus was the slowest at completing the test on average.
Answer: B. It can be concluded that the strength training program does not reduce the number of muscular injuries that occur during an athletic event.
Step-by-step explanation: In the question it states the average number of muscular injuries for athletes enrolled in the strength training program is equal to the average number of muscular injuries for athletes not enrolled in the strength training program.
So here is the answer to the given question above. Analyzing the given figure, we can see that at 0 miles, the cost is 25. Between 0 and 40 miles, the cost rises by 10. Therefore, the function that would represent this situation would be this: <span>f(x) = (10/40)x+25
</span><span> f(x) = 1/4 *x+ 25
f(x) = 0.25x + 25
Hope this is the answer that you area looking for. </span>
