Assume that the numbers of a data set are arranged in ascending order. which statement about the third quartile is true? all of the numbers lie below the third quartile. all of the numbers lie above the third quartile. 50% of the numbers lie below or on the third quartile, and the remaining 50% lie above it. 25% of the numbers lie below or on the third quartile, and the remaining 75% lie above it. 75% of the numbers lie below or on the third quartile, and the remaining 25% lie on or above it.

75% of the numbers lie below or on the third quartile, and the remaining 25% lie on or above it.

Step-by-step explanation:

In any data set, if arranged in ascending order, the mid value gives the median.

If there are even number of entries, the middle value of the mid two entries average would be the median.

I quartile is the entry below which 25% of the entries lie and III quartile is one above which 25% of the entries will lie

Hence out of 4 options given

the last one is the correct answer

75% of the numbers lie below or on the third quartile, and the remaining 25% lie on or above it.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

step-by-step explanation: it is d
