Answer:
Step-by-step explanation:
If we have the expression
, we have to think about exponent rules.
If we have , then the value will be equal to
.
So simplified will be
Converting and
into fifteenths (lcm) gets us
.
We can convert into a radical by taking the denominator root of x to the numerator.
.
Hope this helped!
Let's assume time taken by plane on one way distance as 't'
The total flying time in both directions was 10.5 hr
so, time taken in other direction =10.5-t
now, we are given
A plane averaged 500 mph on a trip going east
so, total distance of one way is
total distance of other way is
now, we can that distance is same from both sides
so, we get
now, we can solve for t
now, we can find one way distance

Answer:
The correct options are 2 and 4.
Step-by-step explanation:
From the given box plot it is clear that
We know that these number divides the data in four equal parts.
25% of the data values lies between 50 and 110. Therefore option 1 is incorrect.
Seventy-five percent of the data values lies between 20 and 50. Therefore option 2 is correct.
It is unlikely that there are any outliers. This statement is not true because the is a huge difference between third quartile and maximum value.
Therefore option 3 is incorrect.
The interquartile range is
Therefore option 4 is correct.
The range is
Range = Maximum-Minimum
Therefore option 5 is incorrect.
