Hep can someone look at this question
A box has a total of 245 computer chips. Kate collected a random sample of size 100 chips from this box and she measured their diameters in mm. She divided the chips into 4 different groups
based on their date of production, she selected randomly one group and included every chip in this
group.

a. What is the population?
b. What is the size of the population?
c. What is the sample?
d. What is the sampling method that Nasser used to select his sample?
e. Is the variable measured quantitative or qualitative? And what is its level of measurement?​​

step-by-step explanation:

cats

r and t.

both are 64 degrees.

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

where does the z at is it on the x axes or on the y axes any way if it is on the y axes put it horizontally and if it is on the x axes put it vertically
