Answer:

The correct option is A) Once an individual is​ selected, the individual cannot be selected again.

Step-by-step explanation:

Consider the provided statement.

Without​ replacement mean each population sample unit has only one opportunity in the sample to be chosen.

For example:

If a bag contains 5 red and 3 white ball and you randomly select a white ball, the probability of selecting the white ball is 3/8.

Now if the experiment is done by without replacement that means the white ball (which you have selected) is no longer the part of the sample space.

Hence, we can say that once an individual is​ selected, the individual cannot be selected again.

Thus, the correct option is A) Once an individual is​ selected, the individual cannot be selected again.

Area of triangle=1/2(base×height)
360=1/2((4x-2)(7x+5))
720=(4x-2)(7x+5)
FOIL the binomial
720=28x^2+6x-10
Bring 720 to the other side
28x^2+6x-10-720=0
28x^2+6x-730=0
Factor 2 out
2(14x^2+3x-365)=0
Factor 2(14x+73)(x-5)=0
x-5=0
x=5
It can't be 14x-73=0 because the length can't be negative.
You're welcome.

A windowpane is 28 centimeters by 96 centimeters. What is the distance between opposite corners of the windowpane? ( In cm)
melisa1 [442]

Answer:

100 cm

Step-by-step explanation:

Using the Pythagore theorem :

Imagine that your window is a triangle, and that the distance you search is AC

So you have :

AC² = AB² + BC²

AC² = 28² + 96²

AC² = 784 + 9216

AC² = 10000

AC = √10000

AC = 100
