This picture of a wall hanging is made of congruent 30° − 60° − 90° triangles with height 6 cm and hypotenuse 12 cm. What is the

Mean = 12000
Standard Deviation = 2000

Our task is to determine how many standard deviations 14,500 is from the mean.
This requires us to compute the z-score

A z-score indicates how far a sample value is from the mean in terms of standard deviations. A positive z-score signifies that the sample value exceeds the mean.

The formula for calculating the z-score is = (Sample Value - Mean) / Standard Deviation
Thus,
Z-score =

This indicates that 14,500 is 1.25 standard deviations higher than the mean of 12,000.

You can calculate 400+200 or sum 368+231= 599 and then round your result, which gives 600

Answer:

The correct choice is the third one.

Step-by-step explanation:

Answer:

2.CE lies on line m.

4.Ray AD is identical to ray AC.

6.Angle ECB is formed by CE and CB.

Step-by-step explanation:

A diagram has been provided.

Our task is to identify the valid statements regarding the diagram.

1.CB is found on line n.

CB does not align with line n since points C and B do not lie on that line.

Thus, this statement is false.

2.CE is situated on line m.

CE is indeed positioned on line m because points C and E are both on this line.

This statement is accurate.

3.Ray BC is equivalent to ray CB.

A ray begins at a single point and continues indefinitely without a terminal point.

Ray CB starts at point C and stretches out from point B.

However, ray BC does not exist.

This statement is therefore false.

4.Ray AD is equivalent to ray AC.

Both AD and AC are rays.

They are equivalent since both originate from point A and extend in the same direction.

5.Angle EAD is formed from AE and DA.

This is false because angle EAD is created by ray AE and ray AD, not by ray DA.

6.Angle ECB is generated by CE and CB.

This is true as angle ECB is made by ray EC and ray BC.
