Answer:
Mean is the measure of central tendency is most appropriate to describe the given data.
Step-by-step explanation:
We are given the following in the question:
The distribution of time in seconds is a bell shaped distribution that is a normal distribution.
Properties of a normal distribution:
- The mean, mode and median for a normal distribution are equal.
- The mean divides the data into two equal parts.
- The area under the graph is 1.
- Thus, mean is the most appropriate measure of central tendency for normally distributed data.
Thus, the correct answer is
Mean is the measure of central tendency is most appropriate to describe the given data.

Answer:
A Composite figure
Step-by-step explanation:
An irregular shape that can be split into familiar shapes such as rectangle, triangles and circles is called a Composite figure.
A Composite figure may easily split into the familiar shapes such as triangles, rectangles and circles in order to find the area of these shapes.
Thus, area of such figures can be easily found out by a composite figure.
25. time = distance/speed
It took about 432 milliseconds for the ball to travel to the batter.
26. 15 cans at Save Rite will cost 5 times the amount for 3 cans, so will be
... 5×$5.25 = $26.25
15 cans at Spend Less will cost 3 times the amount for 5 cans, so will be
... 3×$7.50 = $22.50
Maria paid $22.50 at Spend Less.
27. Simple interest is computed using
I = Prt . . . . where P is the principal, r is the annual rate, and t is the number of years.
Filling in the numbers gives the interest charge.
I = $8000×0.065×4 = $2080
Malik pays back the principal plus interest, so pays $8000 +2080 = $10,080.
