Rylee took five test in science.

each test had a different score.

the mean score of the test was 90%.

the median score of the test was 85%.

based on the information select the two statements it must be true.

- More than half the scores were 85% or greater.

- At least one score was exactly 85%

Step-by-step explanation:

These two answers come from the fact we have a median calculated.

The median of a sample of an odd number of values (like 5 in this case) is one of the values.  So, 85% is a result of one of the tests Rylee took.

Since 85% is the median, it means it has 2 values above and 2 value below... counting the 85% itself, that makes 3 results with 85% or greater.  Since there is only 5 test results in the sample, 3/5 are 85% or greater... so more than half.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
