Answer: The margin of error is 12.74.
Step-by-step explanation:
Since we have given that
Standard deviation = 6.5
Mean = 255
Let 95% level of significance,
So, z value = 1.96
We need to find the "Margin of error":
So, it becomes :
Margin of error = Standard deviation × z-value
Margin of error = 
Hence, the margin of error is 12.74.
Step-by-step explanation:
since KLJ is a parallelogram, it can be split into 2 congruent triangles, as seen above. The angles remain the same, so we know angle KJL is also 25 degrees. Using the triangle angle sum theorem (all sides of a triangle add up to 180 degrees), we can determine the missing angle measure is 25 degrees. It would have been nice if the question told us JKLM was also a rhombus.
Answer:
$60.8
Step-by-step explanation:
Twenty percent of 76 is,
→ 20% of 76
→ (20/100) × 76
→ 1520/100
→ [ $15.2 ]
The reduced price of the item is,
→ 76 - 15.2
→ [ $60.8 ]
Hence, the price is $60.8.
