Answer:

Step-by-step explanation:

Given a set of data sorted from smallest to largest, i.e. arranged in ascending order we are to find out the median, I and III quartiles

We know that the median is the middle entry of data arranged in ascending order

Q1 is the entry below which 25% lie and Q3 is one above which 25% lie

Hence proper definition would be

d. The first quartile is the median of the lower half of the data below the overall median.

The second quartile is the overall median

The third quartile is the median of the upper half of the data above the overall median.

Option b is wrong becuase mean is not necessary here. Option a is wrong because this has nothing to do with std deviation

Option c is wrong since minimum value cannot be q1

Option e is wrong because we have exactly 25% lie below Q1

3 1/4 - 2 1/3 what is the answer please explain

anastassius [24]

Answer:

it is 0.916 (the six is repeated. a line under a number means repeated in this case)

Step-by-step explanation:

First you take 3 1/4 and turn it into 13/4 and turn 2 1/3 into 7/3 and transform those into decimals 13/4 = 3.25 and 7/3 = 2.3 and subtract which is 0.95 plus the fact that the three is repeated which gets your answer of 0.916 however you should say that if they want you to simplify it to two/three decimals, it is 0.95 but if they want it exact it is 0.916 with the six being repeated

Perform the indicated operation. f(x) = x^3 + 5x g(x) = 4x Find (f . g)(x)

cestrela7 [59]

Step-by-step explanation:

$f(x) = {x}^{3} + 5x \\ g(x) = 4x \\ \\ \therefore \: (f.g)(x) = f(x) . g(x) \\ = ( {x}^{3} + 5x ).4x \\ = {x}^{3} .4x + 5x.4x \\ \red{{ \boxed{\bold{\therefore \: (f.g)(x) = 4 {x}^{4} + 20 {x}^{2} }}}}$

Complete the equation of the line through (3, -8) and (6, -4)

hammer [34]

Answer:

we have,

y-y1=m(x-x1)

or, y+8=4/3(x-3)

or, 3y+24=4x-12

or, 4x +3y+36=0 is the required equation
