The five-number summary of the ages of passengers on a cruise ship is listed below. Min 1 Q1 20Median 29 Q3 38Max 80 Consider th
Eddi Din [679]

Answer: b. Only statement (ii) is correct.

Step-by-step explanation:

The given five-number summary of the ages of passengers on a cruise ship is listed below.

Min 1    Q_1 20     Median 29     Q_3 38         Max 80

Inter-quartile range = IQR=Q_3-Q_1=38-20=18

  • According to the 1.5(IQR) criterion for outliers : An data value is an outlier if it lies below Q_1 - 1.5(IQR) or  above Q_3 + 1.5(IQR).

Here , Q_1 - 1.5(IQR) =20-1.5(18)=-7

Q_3 + 1.5(IQR)=38+1.5(18)=65

Since the minimum value> Q_1 - 1.5(IQR) ( ∵ 1 > -7)

It means there is no value below Q_1 - 1.5(IQR)  , so there is no low -outlier.

⇒ Statement (i) "here is at least one passenger whose age is a low outlier. " is false.

But the maximum value > Q_3 + 1.5(IQR) (∵  85 > 65)

It means there are values above Q_3 + 1.5(IQR).

⇒Statement (ii) "There is at least one passenger whose age is a high outlier" is true.

Hence, the correct answer is b. Only statement (ii) is correct.

Find the 66th term in the following arithmetic sequence: -92,-85,-78,-71,.......
grandymaker [24]

9514 1404 393

Answer:

  363

Step-by-step explanation:

The n-th term of an arithmetic sequence is given by ...

  an = a1 +d(n -1)

Here, the first term (a1) is -92, and the common difference is (-85 -(-92)) = 7. The 66th term is ...

  a66 = -92 +7(66 -1) = -92 +455

  a66 = 363

What is -121-4x=39+6x
vodka [1.7K]
So we're trying to solve for x. To do this we need to balance the equation.
-121 -4x = 39 + 6x
Get x on one side; add 4x to both sides.
-121 = 39 + 10x
Subtract 39 from both sides (remember when subtracting a negative to a negative, it's basically just adding with negative signs).
-160 = 10x
Divide both sides by 10.
x = -16.
Hope this helps!
