Answer:
[34,54]
Step-by-step explanation:
-The empirical rule states that the 95% of the sampled observations will fall within two standard deviations of the mean for a normally distributed population.
Where:
- 68% is the first standard deviation
- 95% is the second standard deviation about the mean
- 99.7% is the 3rd standard deviation about the mean.
-Therefore. the middle 95% interval is calculated as:
Hence, the interval is [34,54]

Answer:
Areas of the colored parts are equal
Step-by-step explanation:
Given Mauricio divided two identical rectangles into equal parts.
Now given Mauricio colored one part of each rectangle. we have to tell about the true statement of colored parts.
Two identical rectangles means the rectangle having equal areas. He divides these two into equal parts and shaded one of each part
Let area of rectangle is x
∴ Colored part area = → (1)
Similarly, other rectangle area identical to above rectangle is x
∴ Colored part area = → (2)
From above eq (1) and (2), we get
Areas of the colored parts are equal which is equals to
