The following data give the prices of seven textbooks randomly selected from a university bookstore. $93 $173 $107 $125 $56 $163 $144 a. Find the mean for these data.

Answers

Answer:

Mean = $123

Standard deviation = 10190

Variance = 1698

Step-by-step explanation:

Mean=?

      = sum of all numbers/ Total numbers

    a  =  93+173+107+125+56+163+144 / 7  = 861/7 = $123

Standard deviation=?

we know that = Sqareroot [ Sum (y)²] / N

we need deviation:

=    x-a         =  y   ;    y²                

  = 93-123 = -30  ;   900

   =173-123 = 50  ;    2500

  =107-123  =  -16 ;   256

   =125-123  = 2   ;    4

   =56-123   =  -67 ;   4489

   =163-123  =  40  ;   1600

   =144-123   =  21   ;   441

Sum of y²            =   10190.

  = Square root [  10190 / 7 ]

  =  38.1

Variance = ?

        = Sum ( y)² / N-1

        =  10190 / ( 7-1)

       = 10190 /6

     = 1698

The hypotenuse of one side of a right angled triangle are 5cm and 4cm respectively. what is the length of the other side​

Answers

Answer: 3cm

Explanation:

We can use Pythagorean’s theorem to find that other side:

a^2 + b^2 = c^2
a^2 + 4^2 = 5^2
a^2 = 25 - 16
a^2 = 9
a = 3

Therefore, the other side is 3cm

Answer:

Hypotenuse is the longest side in a triangle.

a^2=b^2+c^2.

5^2=4^2+c^2.

c^2=25-16.

c^2=9.

c=√9.

c=3cm.

1. 2x-y≤-6
2. 5x+4y ≥20
​

Answers

Answer

2x-y <or =-6

2x<or=-6+y

divide both sides by 2

x<or=1/2y+3

5(1/2y+3)+4y>or=20

5/2y+15+4y>or=20

5/2y+4y>or=20-15

13/2y>or=5

divide both sides by 2/13

y>or=10/13

2x-10/13<or=-6

2x<or=-6+10/13

2x<or=-68/13

divide both sides by 2

x< or =-34/13
