There is a formula about the distance between two points in the plane.
M(a,b) and Т(с,d)
The distance between M and N is L=sqrt[(a-c)^2+(b-d)^2)]
So the <span>magnitude of this vector is  sqrt[(-6+10)^2+(-4+4)^2]=sqrt(16+0)=4
b=d This means that vector JK is</span> <span>parallel to the OX axis(there is a picture)</span>

which set of side lengths form a right side?a) 3ft,6ft,5ft b)50 in,48in,14in c)53m,48m,24m d)8cm,17cm,14cm​
muminat

Answer:

<h2>b) 50in, 48in, 14in</h2>

Step-by-step explanation:

If <em>a ≤ b < c</em><em> </em>form of a right side, then <em>a² + b² = c²</em>

a) 3ft, 6ft, 5ft

3² + 5² = 6²

9 + 25 = 36

34 = 36        <em>FALSE</em>

b) 50in, 48in, 14in

14² + 48² = 50²

196 + 2304 = 2500

2500 = 2500     <em>CORRECT :)</em>

c) 53m, 48m, 24m

24² + 48² = 53²

576 + 2304 = 2809

2880 = 2809     <em>FALSE</em>

d) 8cm, 17cm, 14cm

8² + 14² = 17²

64 + 196 = 289

260 = 289    <em>FALSE</em>

What is the Mean Absolute Deviation or MAD for each city?
ira [324]

Answer:

A: ⅚

B: ⅚

Step-by-step explanation:

City A: 4, 3.5, 5, 5.5, 4, 2

Mean: sum/n

= 24/6 = 4

|x - mean|: 0, 0.5, 1, 1.5, 0 , 2

MAD = sum|x - mean|/n

5/6 = 0.833

City B: 5, 6, 3.5, 5.5, 4, 6

Mean: 30/6 = 5

|x - mean|: 0, 1, 1.5, 0.5, 1, 1

MAD = sum|x - mean|/n

5/6 = 0.833
