1. What expression is same as (a. a.a)(b. b)?
A. (4a)(2b)
C. a" b2
B. a2 b2
D. 8ab​

a^3b^2

Step-by-step explanation:

Recall that the first law of indices states that

a^x * a^y = a^(x+y)

Hence the expression  (a.a.a)(b.b)

= a^(1+1+1) * b^(1+1)

= a^3b^2

This is the product of a raised to the power of 3 and b raised to the power of 2

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
