Which set of ordered pairs has point symmetry with respect to the origin (0, 0)? (5, 4), (-5, -4) (5, 4), (5, -4) (5, 4), (4, 5)
Sidana [21]

The set of ordered pair that has point symmetry in respect to origin is (5, 4), (-5, -4).

<h3>What is the point of symmetry?</h3>

This is a term that is used to refer to the points that are on the same distance from the origin but are on opposite sides.

The line that connects the points are known to move through the origin such that when measured on the graph, the distances between these points but they are opposite because they are in negatives and positives on the two sides.

The probability density function of the time it takes a hematology cell counter to complete a test on a blood sample is f(x)=0.0
faltersainse [42]

Answer:

a) 0.2

b) 0.4

c) Mean  = 62.5

Variance = 52.083              

Step-by-step explanation:

We are given the following information in the question:

f(x) = 0.4\\

a = 50, b = 75

We are given a uniform distribution.

a) P(x > 70)

P(x > 70)\\=1 - P( \leq 70)\\\\=1-\displaystyle\int^{70}_{50}0.04 ~dx\\\\=1-0.04(70-50)\\=0.2

b) P(x < 60)

P(x < 60)\\\\=\displaystyle\int^{60}_{50}0.04 ~dx\\\\=0.04(60-50)\\=0.4

c) Mean:

\mu = \displaystyle\frac{a+b}{2}\\\\\mu = \frac{50+75}{2} = 62.5

Variance:

\sigma^2 = \displaystyle\frac{(b-a)^2}{12}\\\\= \displaystyle\frac{(75-50)^2}{12} = 52.083
