<span>the car would have been traveling at 10kmph for the remaining 25 percent of the trip. 50 times 3 (25 percent segments) is 150, use math to solve for four 25 percent segments.</span>
Answer:
The histograms are missing, but ill try to answer it nonetheless.
Here we have that the standard deviation is bigger than the mean, this means that we will not see one of the ends (the smaller one) of our bell.
And we have a normal distribution, so we have a gaussian bell.
We will have that the peak of our bell is at the value x = 1.1
The histogram will start with a kinda high value at x = 0, it will get to the maximum at x = 1.1 and it will decrease as a normal bell, and knowing that the distance between the mean value and the point where the bell almost is almost zero, is equal to 3 standard deviations, we can expect to see this at x = 1.1 + 3*1.5 = 1.1 + 4.5 = 5.6

Answer:
50% of all students scored more than 48 marks.
Step-by-step explanation:
1) The baseline of the box, in a box plot is the first quartile, the line in the middle is the median or Q2 and the last line (or top line) is the third quartile. Namely,
2) The Question says "nobody took 30, 48 or 70 as their grades. But 120 students gained less than 70", i.e. 120 are within the 75% of the sample.
3) If then 50% of the students scored more than 48. And 50% of the students scored less than 48. That is also known as the Median.
So 50%, the half of all students scored more than 48 marks.
