Matthew and Alicia wanted to know who could unpack their schoolbag faster. Matthew did it in 63.4 seconds and Alicia did it in 58.3 seconds. Who won? By how much?

Matthew won because 63.4 is greater than 58.3 .Matthew won by 5.1 seconds because 63.4-58.3 =5.1  .Hope this helps :D

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

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
