Answer
The IQR of the data set is 368.
Explanation
To find the interquartile range, you first need to find the median of the data set. Then, you find the median of the median and subtract them. This might be a little confusing but I'll walk through everything.
First, put the data set in order from least to greatest; 21 78 90 111 381 456 676. Find the median. The median of this data set is 111, since it is the middle number when the data set is ordered from least to greatest.
To find the Q1 and Q3 of the set, you have to find the median of the median.
The set right now is 21 78 90 111 381 456 676. Remove the 111 (if there were an even amount of numbers in the set, you wouldn't remove the 111 and you would just split the data set in half). Now you have two sets: 21 78 90 and 381 456 676. The median of the first set is 78 (this is the Q1) and the median of the second set is 456 (this is the Q3).
To find the interquartile range, subtract the Q1 from the Q3. 456-78=368.
Answer:
There are two correct answers for this question depending on how you think of it.
3x or -3
Step-by-step explanation:
3x could be right because the rest of them are negative. But also on the other case -3 because the rest have x's and this one doesn't

Have a nice day!
Answer:
9 units
Step-by-step explanation:
These distances are measured on a number line. Locate -3 and move your pencil point 3 units to the right to arrive at 0. Next, move your pencil point 6 units further to the right. The sum effect of these motions are the distance between -3 and 6, which is 9.
D) because if the probability it lands on a 2 is 1/5, it means out of 5 numbers, only one is a 2. Thus, the other 4 must be not a 2. So when it asks "<span>What is the probability that the spinner will land on a number other than 2?" the answer is 4/5</span>
