Answer:

Step-by-step explanation:

distance = square root [ $(x2-x1)^{2}$ + $(y2-y1)^{2}$ ]

where you have two points on the line

Point 1 = P1 = (x1,y1)

astraxan [27]

Answer:- A line is the undefined geometric term can be described as a one-dimensional set of points that has no beginning or end.

Explanation :-

In geometry, there are three undefined terms : 1) point 2) line 3) plane

A point has zero dimensions . It has two dimensions in plane and three dimensions in space.
A line is said to be a one dimensional set of points that has no beginning or end.It has only length.
A plane has two dimensions.
Distance is not a geometic term.

Answer: c. -2.15

Step-by-step explanation:

As per given we have:

Null hypothesis : $H_{a}: p\geq0.80$

Alternative hypothesis : $H_{a}: p$

let p be the proportion of firms in the manufacturing sector offer child-care benefits

A random sample of 390 manufacturing firms is selected and 295 of them offered child-care benefits.

sample size : n= 390

sample proportion : $\hat{p}=\dfrac{295}{390}=0.7564$

Test statistic for proportion :

$z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}$

Substitute the values , we get

$z=\dfrac{0.7564-0.80}{\sqrt{\dfrac{0.80(1-0.80)}{ 390}}}$

$z=\dfrac{-0.0436}{\sqrt{0.000410256410256}}$

$z=-2.15257752474\approx-2.15$

Hence, the value of test statistic = -2.15

Correct option is c. -2.15 .
