Answer:

Median = 116.

First quartile = 102.

Step-by-step explanation:

There is a total of 280 scores so the median will be the 140th score.

The first box gives 26 , second 34 = 60

The 3rd box contains 100 giving a total of 160 so the median lies in this third box.

140 - 26 - 34 = 80..

That gives a value of 80 / 5 = 16.

The median is 100 + 16 = 116.

The lower quartile is the 70th score

26 + 34 + 10 = 70.

So it is 100 + 10/5 = 102.

If y2 = x3 + 2, which statement is true? The equation is a function at all values of x. The equation is not a function. The equa

Answer:

The equation is not a function.

Step-by-step explanation:

We are given that

$y^2=x^3+2$

$y=\pm\sqrt{x^3+2}$

Function: It is mapping between the values of two sets A and B.

Each element of A has unique value in set B.

By definition of function

In given function

y has no unique value for each value of x.

Substitute x=0

$y=\pm \sqrt{0+2}=\pm \sqrt 2$

Hence, it is not a function.
