Answer:
The value remain unchanged.
Step-by-step explanation:
By Z score, we mean:
Z = 
, if we substitute the given values of mean and standard deviation, we obtain the z score value. That is,
Z = 
= 85/12 = 7.083333.
NB: We assume that mean and standard deviation are in the same units.
Answer:
- Kyle is correct, the quadrilaterals are not similar
Step-by-step explanation:
Measure the corresponding sides and verify if the ratios are same or not.
<u>Corresponding sides:</u>
- AB and LM, BC and MN, CD and NO, AD and LO
<u>The measures, using coorinates and the distance formula:</u>
- AB = √(2-1)² + (4-3)² = √2
- LM = √(16-14)² + (4-6)² = √8 = 2√2
- BC = √(5-2)²+(5-4)² = √10
- MN = √(23-16)²+(2-4)² = √53
<u>We can see the ratios of the two pairs are not same:</u>
- AB/LM = 1/2
- BC/MN = √10/53
- 1/2 ≠ √10/53
We can state that Kyle is correct
The answer is .35 not 3.5
