It is known that the population mean on the math portion of the sat is 500, with a standard deviation of 100. assume that the average math sat score for freshmen entering sullivan college is 550, with a standard deviation of 110. does the math performance of students entering your college differ significantly from that of all individuals taking the sat? what statistical analysis is used to answer this question? a) single-sample t test
b) z test
c) standard deviation analysis
d) dependent-samples t test

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

step-by-step explanation:

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24

answer:

24pi or letter c
