Help me out please !! Thank you

B. 70

Step-by-step explanation:

So the person gets a score of 15 on the tutorial level.

The line of best fit is that line down the middle of the graph trying to be closest to all of the plot points

You need to go to the x-axis because that is the tutorial level value that it is asking for. Find 15 on the axis and go up to the line of best fit

Based on the line of best fit, the average person would most likely reach a score of 70 on the main level after scoring a 15 on the tutorial level

Hopefully you understand this now, this is my first ever answer

b.-4 units

all you   do is count how many times you move

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
