skelet666 [1.2K]

Answer:

Pr(≥ 70%) = 2/5 = 0.4

Step-by-step explanation:

This question is incomplete as we can't get an exact answer without the dot plot diagram.

We can tell from the question, we are to determine the probability of having ≥ 70% students that play sports

The dot plot diagram used in solving the question has been attached.

Total number of samples = 20

From the dot plot, 50% of students play sport. That is, 50% have more people playing sport than others.

The chance of getting a sample proportion of 70% or greater= probability of students that like sports ≥ 70%

= (sum of people that like sports ≥ 70%)/(total number of sample)

Pr(≥ 70%) = (4+3+1)/20

Where Pr = probability

Pr(≥ 70%) = 8/20

Pr(≥ 70%) = 2/5 = 0.4

Round 1.5 to one decimal place
xxMikexx [17]
If the last digit in 1.50 is less than 5, then remove the last digit.

If the last digit in 1.50 is 5 or more and the second to the last digit in 1.50 is less than 9, then remove the last digit and add 1 to the second to the last digit.

If the last digit in 1.50 is 5 or more and the second to the last digit in 1.50 is 9, then remove the last digit, make the second to last digit 0, and add 1 to the number to the left of the decimal place.

When rounding 1.50 to one decimal place we use One Decimal Place Rule #1. Therefore, the answer to "What is 1.50 rounded to 1 decimal place?" is:
