Apyramid has a square base that is 160 m on each side. what is the perimeter of the base in kilometers? question 19 options:

0.64 kilometres

Step-by-step explanation:

Step 1: Find the perimeter in metres

Perimeter of square = 4 x (Length)

Perimeter = 4 (160)

Perimeter = 640 metres

Step 2: Convert from metre to kilometre

1 km = 1000 m

x km = 640 m

Cross multiply

1000x = 640

x = 0.64 kilometres

Therefore, the perimeter of the square base is 0.64 kilometres.

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
