Answer:
The length of this rectangle is 8m.
Step-by-step explanation:
The problem states that the perimeter of a rectangle is twice the sum of its length and it’s width. So

The problem also states that the perimeter is 22 meters. So:

.
Also, it states that I is the length and it is 2 meters more then twice it’s width. So

What’s its length?








The width is 3m. The length is in function of the width, so:



The length of this rectangle is 8m.

Answer:
i and iii) In the figure attached part a we have the illustration for the area required for the probability of less than 2 hours and in b the illustration for the probability that X would be between 2 and 4
ii)
And using the normal standard table or excel we got:
iv)
And we can find the probability with the following difference and usint the normal standard distirbution or excel and we got:
Step-by-step explanation:
Let X the random variable that represent amount of time people spend exercising in a given week, and for this case we know the distribution for X is given by:
Where
and
Part i and iii
In the figure attached part a we have the illustration for the area required for the probability of less than 2 hours and in b the illustration for the probability that X would be between 2 and 4
Part ii
We are interested on this probability:
We can use the z score formula given by:
Using this formula we have:
And using the normal standard table or excel we got:
Part iv
We want this probability:
Using the z score formula we got:
And we can find the probability with the following difference and usint the normal standard distirbution or excel and we got:
