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:
4 consecutive goals
Step-by-step explanation:
If 3 of last 10 field goals = 30%
Which is equivalent to
(Number of goals scored / total games played) * 100%
(3 / 10) * 100% = 30%
Number of consecutive goals one has to score to raise field goal to 50% will be:
Let y = number of consecutive goals
[(3+y) / (10+y)] * 100% = 50%
[(3+y) / (10+y)] * 100/100 = 50/100
[(3+y) / (10+y)] * 1 = 0.5
(3+y) / (10+y) = 0.5
3+y = 0.5(10 + y)
3+y = 5 + 0.5y
y - 0.5y = 5 - 3
0.5y = 2
y = 2 / 0.5
y = 4
Therefore, number of consecutive goals needed to raise field goal to 50% = 4

If they drive in opposite directions it will take 1.66 hours for them to get 225 miles away from each other.
Answer:
jack= £140
Jill= £60
Step-by-step explanation:
7+3= 10= total amount of parts
200/10=20
1 part-20
7*20=140 (jack)
3*20=60(jill)
