Let's begin by listing out the information given to us:
There are four students: n = 4
Number of students to be selected: r = 2
To calculate the combination of 2 students to be chosen, we use:
Therefore, there 12 possible combinations from these
The interquartile range (IQR) is 15.
To find the IQR, you must:
1) Find the median
2) Split the data set in two at the median.
3) Find the medians from both the groups you made in Step 2
4) Label the smaller one Quartile 1 and the larger one Quartile 3 (Hint: The median is Quartile 2)
5) Subtract: Quartile 3 - Quartile 1
Answer:
You should know how to integrate both sides
Step-by-step explanation:
This is the answer. I did it and got that. You do distributive and then combine like terms.
Answer:
56
Step-by-step explanation:
The probability both spiners land on red: 0,5*0,6=0,3 (0,5 is A spine lands on red and 0,6 is B spiner lands on red)
The number of both spiners land on red is 84.
So we have:
X——>100%
84——->30%
X=8400/30
X=280
The total number of all spines A and B for onse.
The probability to both spiners land on blue is:
0,5*0,4=0,2 (0,5 is probabiliti to A lands on blue, 0,4 is B lands on blue)
The number of both spiners land on blue is:
280*0,2=56
