The bar graph shows the number of days per year that students in each grade spend testing. based on the trend shown, what is the best prediction for the number of days testing, for 2nd grade?

15

20

25

30

The BEST prediction for the number of days testing, for 2nd grade is:

                                             25

From the bar graph we observe that the grades first increases and then decreases and hence, the bar graph is symmetric about the 3 rd grade.

Also, the value to the left are slightly higher then those on the right.

and hence the number of days would be slightly higher than 25.

        Hence, the value will be close to 25.

answer: c

step-by-step explanation: because you don't have to draw a point of intersection. couldyou give me brainliest?

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
