Determine whether the following graph can represent a normal curve.
A
x
Could the graph represent a normal curve? Select all that apply.
DA. No, because the graph has a single peak.
B. No, because the highest point of the graph does not occur at the median
C. No, because the graph is not always greater than or equal to zero.
D. Yes, because the graph may not satisfy all of the criteria for

answer: need picture of problem

step-by-step explanation:

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

yes

step-by-step explanation:

yes

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.
