Ms. zimmer has pink and purple pens. she has 3 times the number of pink pens as purple pens. if a pen is chosen at random, what is the probability she will pick pink?

C, 3/4

Explanation:

If there is 1 purple pen, and pink pens have 3x the amount of purple pens, there are 3 pink pens. There are 4 pens in all so 3 out of the 4 pens are pink.

2 x t divided by n

step-by-step explanation:

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
