The multiplicative inverse of a number x is a number y such that their product xy is 1.

So, we want a number such that

$-\dfrac{3}{8}\cdot x = 1$

Multply both sides by 8:

$-3x=8$

Divide both sides by 3:

$-x=\dfrac{8}{3}$

Change sign to both sides:

$x=-\dfrac{8}{3}$

I don’t know if there is an outlier or not how can you tell

SIZIF [17.4K]

To find an outlier, multiply the IQR by 1.5

172,500 * 1.5 = 258,750

now, u add that to Q3.....545,000 + 258,750 = 803,750....anything above this number is an outlier

now,u subtract that from Q1....372,500 - 258,750 = 113,750....anything below that is an outlier

u have already done this...u have found the higher end and the lower end....so anyting larger then the higher end or lower then the lower end is ur outlier

so in ur data, there is only 1 outlier and that is 933.....130 is not an outlier because it is not less then 113,750.

Write a own real-world scenario where the Pythagorean Theorem can be applied to find a missing piece. You can choose to write a

Ne4ueva [31]

If you are mowing a section of a lawn but want to make sure you only mow so much. Say half of a square lawn, if you know that the 2 sides of the fence are each 20 yards in length, you can apply the formula to find the distance of the diagonal. That way you know exactly how much you have mowed. draw a square, cut a diagonal through it, make the 2 sides labaled as 20 and then its 20 squared plus 20 squared = c squared. Hope this helps!
