Mr. Li is a math teacher at Pinkston High School who is preparing his students to take the SAT test. He collected data from 10 students who took the test last year and presented this information to the students in a table. Which linear regression equation best represents the line of best fit for the data if represents the number of hours spent studying? A y= 344.19x+22.54
B y= 344.19x−22.54
C y= 22.54x+344.19
D y= −22.54x+344.19

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.
