What is the distance from C to D?<br><br> A. 5 units<br> B. 1 unit<br> C. 25 units<br> D. 7 units
Vera_Pavlovna [14]

Answer:

Option A

Step-by-step explanation:

According to the distance formula , for any 2 points P & Q whose coordinates are (x¹ , y¹) and (x² , y²) respectively. So ,

PQ = \sqrt{(x^{2} - x^{1} )^{2} + (y^{2} - y^{1})^{2} }

NOTE = HERE x² , y² DOESN'T MEAN THE SQUARES OF x & y . THEY ARE JUST COORDINATES.

According to the question ,

Coordinate of C = (2 , -1)

Coordinate of D = (5 , 3)

Using distance formula ,

CD = \sqrt{(5-2)^{2} + (3 -(-1))^{2} }

=> CD = \sqrt{3^{2} + 4^{2} } = \sqrt{9 + 16} = \sqrt{25} = 5

Orders for a computer are summarized by the optional features that are requested. The proportion of orders with no optional feat
kap26 [50]

Answer: 0.28

Step-by-step explanation:

Let´s name the proportion of orders

  • with no optional features: "N"
  • with one optional feature: "O"
  • and the proportion of orders with more than one optional feature: "M"

<em>The sum of all of these proportions is equal to the total quantity of orders.</em>

Therefore,

N + O + M = 1

Then, substracting N and O on each side of that equation,

the proportion of orders with more than one optional feature (M) is:

M = 1 - N - O

M = 1 - 0.38 - 0,34

M = 0.28
