lys-0071 [83]

Answer:

L= Q_1 - 1.5*IQR = 210 -1.5*40 =150

U= Q_3 + 1.5*IQR = 250 +1.5*40 =310

And if we analyze the info provided we have 500 values

Tails: 160,165,167,171,175,...,268,269,269,269,270,270

So as we can see on the tails any values is <150 or >310 so then for this case we cannot consider as outliers any of the values on the tails of the distribution.

Step-by-step explanation:

For this case we have the 5 number summary

(160,210,220,250,270)

So then we have:

minimum = 160 , Q1 = 210, Q2= Median=220, Q3 = 250, Max=270

If we find the interquartile range we got:

IQR = Q_3 -Q_1 = 250-210 =40

For this case we need to find the lower and upper limit with the following formulas:

L= Q_1 - 1.5*IQR = 210 -1.5*40 =150

U= Q_3 + 1.5*IQR = 250 +1.5*40 =310

And if we analyze the info provided we have 500 values

Tails: 160,165,167,171,175,...,268,269,269,269,270,270

So as we can see on the tails any values is <150 or >310 so then for this case we cannot consider as outliers any of the values on the tails of the distribution.

Y = 10x + 50
y = 15x + 30

where y = the amount of money in their account and x = the number of months.
Because "10x+50" is equal to y, and "15x+30" is also equal to y, it must be true that "10x+50" is equal to "15x+30". Then solve for x:

10x+50=15x+30\\-5x=-20\\x=4

Now that you have x, you can plug it in to one of the equations to find y:

y=10x+50\\y=10(4)+50\\y=40+50\\y=90

So x = 4 and y = 90.  Therefore...

After 4 months, both accounts will have the same amount of money; $90.
