Aresearch study investigated differences between male and female students. based on the study results, we can assume the population mean and standard deviation for the gpa of male students are µ = 3.5 and σ = 0.5. suppose a random sample of 100 male students is selected and the gpa for each student is calculated. what is μx¯?

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

the answer to your question is c.)   volcanoes built the mountains and earthquakes tore them down.

step-by-step explanation:

24

step-by-step explanation:

you just have to add the 15 + 9 to get 24

you do this bc you want to find the total of the whole line and those two numbers make up the line
