Answer:

Nominal

Step-by-step explanation:

There are four levels of measurement of data listed below in increasing order:

Nominal

Ordinal

Interval

Ratio

The nominal level of measurement is the lowest level that deals with names, categories and labels. It is a qualitative expression of data e.g Colors of eyes, yes or no responses to a survey, and favorite breakfast cereal all deal with the nominal level of measurement.

Data at this level can't be ordered in a meaningful way, and it makes no sense to calculate things such as means and standard deviations.

By selling a watch on 400 and 460’. Loss and profit happened respectively.if the loss and profit are equal, find cp.

Maslowich

Answer:

430

Step-by-step explanation:

Given :-

By selling a watch on 400 and 460’. Loss and profit happened respectively.
The loss and profit are equal.

And we need to find out the CP .So ,

Let :-

CP be x
Profit and Lost be y .

According to the Question :-

$:\implies$ 460 = x + y ( Profit)

$:\implies$ 400 = x - y ( Loss)

Adding both :-

$:\implies$ 460 + 400 = x + y + x - y

$:\implies$ 860 = 2x

$:\implies$ x = 860/2

$:\implies$ x = 430

Hence the Cost price of the watch is 430 .

A quadrilateral with vertices (-3,2),(-5,-4), (4,6), and (7,0) is dilated by a scale factor of 0.5.

Ksenya-84 [330]

Original vertices:
1 (-3, 2)
2 (-5,-4)
3 ( 4, 6)
4 ( 7, 0)

dilated by a scale factor of 0.50

1) -3*0.50 = -1.5 ; 2 * 0.50 = 1 ⇒ (-1.5,1)
2) -5*0.50 = -2.5 ; -4*0.50 = -2 ⇒(-2.5,-2)
3) 4*0.50 = 2; 6*0.50 = 3 ⇒ (2,3)
4) 7*0.50 = 3.5; 0*0.50 = 0 ⇒ (3.5,0)

B.)
-1.5 -2.5 2 3.5
 1 -2 3 0
