Recall that the mean of a given set of numbers is the sum of the numbers divided by the number of numbers, therefore, the mean of the dataset is:
Now, the range of a data set is the difference between the maximum and the minimum, in this case, the maximum is 99, and the minimum is 15 therefore, the range is:
Finally, the standard deviation is given by the following formula:
where N is the sample size, x_i is an element of the set, and x^- is the mean. The standard deviation of the set is:
<h2>Answer: </h2>
Answer:
The answer is A.
Step-by-step explanation:
First, you have to solve the inequality :
Therefore, x > 2, so only option A is suitable for the x values.
Just means find any whole number inbetween the sets,
1: 3
2: could be anything from 0 to 4
3: -6 or -5
4: -6 or -7
5: -1
6: anything from 1 to 4
Answer:
Step-by-step explanation:
<u>This is the option A</u>
AA
- If two triangles have two of their angles equal, the triangles are similar.
SAS
- If two triangles have two pairs of sides in the same ratio and the included angles are also equal, then the triangles are similar.
SSS
- If two triangles have three pairs of sides in the same ratio, then the triangles are similar.
<u>Other elements mentioned:</u>
- HL- this is a congruence but not similarity
- ASA- same as above
- AAS - neither similarity nor congruence rule
its ither a or b cant tell but im more leanyent to b SOO MY FINAL AWNSER IS B
