Hello!
1 m = 1.094 yards
1 m = 3 ft 3.37 in
1 m = 100 cm
1 m = 0.000621 miles
1 m = 39.37 in
1 m = 100 cm
Therefore, a meter is closest to b. 3 ft.
Answer:
C(r) = 5 + 2.5r
Step-by-step explanation:
An amusement park charges a fee of 5$ each time you enter the park. The cost of each ride is $2.50.
Therefore, the cost of r number of rides inside the park will be $2.5r.
Hence, the expression that shows the cost C (in dollars) as a function of the number of rides r, I go on at the amusement park during one visit will be
C(r) = 5 + 2.5r (Answer)
Answer:
The probability that a randomly selected boy in secondary school can run the mile in less than 368 seconds is P(X<368)=0.011.
Step-by-step explanation:
We have a normal distribution with mean 460 and standard deviation 40 to describe the time for the mile run in its secondary-school fitness test.
We have to calculate the probabiltiy that a randomly selected boy in secondary school can run the mile in less than 368 seconds.
To calculate this, we have to calculate the z-score for X=368:
Then, we can calculate the probability:
Answer: b) statistic
Step-by-step explanation:
- Population = A large groups of individuals sharing the same or similar characteristic by the point og study.
- Sample = It is a subset of population .
- Parameter = It is measure of characteristic in population.
- Statistic = It is measure of characteristic in sample.
Since the average score was taken by the group of 20 which is nothing but the sample.
That means, the average score is an example of<u> statistic</u>.
Hence, the correct option is b) statistic .
