Mr. John tracked the number of hours spent reading by students in two different classes over summer break. Each dot represents a student.

Which statement correctly compares the data?

A.
Class A students generally spent the exact same number of hours reading as class B students.
B.
Class B students generally spent more hours reading than class A students.
C.
Class A students generally spent more hours reading than class B students.
D.
Although the mean number of hours spent reading by class A students is generally greater than the mean number of hours spent reading by class B students, the variability creates too much overlap for any conclusion to be made.
PLZZZ I NEED IT NOW PL ;D

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

step-by-step explanation:

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.
