Frands collects marbles. In her collection are: 8 yellow marbles
4 white marbles
6 purple marbles
10 green marbles
Frands will randomly choose 1 of the marbles. What is the probability that she will choose a
purple marble?​

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

320ft

step-by-step explanation:

120 divided by 3 equals 40

40 times 4=160

160 times 2=320

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75

just a girl thing, i think im cute when im not lol
