Answer: 3/10
Step-by-step explanation:
Question 1: Option D
Area of the parallelogram = 132 cm²
Question 2: Option B
Area of the parallelogram = 3.60 ft²
Solution:
Question 1:
Base of the parallelogram = 6 + 5 = 11 cm
Height of the parallelogram = 12 cm
Area of the parallelogram = Base × Height
= 11 × 12
Area of the parallelogram = 132 cm²
Option D is the correct answer.
Question 2:
Base of the parallelogram = 1.9 + 0.5 = 2.4 ft
Height of the parallelogram = 1.5 ft
Area of the parallelogram = Base × Height
= 2.4 × 1.5
Area of the parallelogram = 3.60 ft²
Option B is the correct answer.

Answer:


And the 68% confidence interval is given by (91.1186, 97.2814)
Step-by-step explanation:
For this case we know that mean time that visitors stay at a museum is given by:

The standard deviation is given by:
And the standard error is given by:
And we want to interval captures 68% of the means for random samples of 25 scores and for this case the critical value can be founded like this using the normal standard distribution or excel:

We can find the interval like this:

And replacing we got:


And the 68% confidence interval is given by (91.1186, 97.2814)
