Answer:
104 degrees
Step-by-step explanation:
Follow the points from Q to T; notice that if the line goes straight across right, this would form a right angle. R is located south of this right angle. That verifies that this is an obtuse angle (more the 90 degrees) but only by a little bit, not enough to go into the 120's.
X^4+3x^3-2x^2-5x+8 can be one example
Answer:
2/3
Step-by-step explanation:
Given that a six sided die with sides labelled with numbers 1,2,3,4,5 and 6 is rolled once.
Since die is said to be equally likely for each number, die is unbiased
P(1) = P(2)=...=P(6) = 1/6
For a number greater than 2, we must not include 2 and hence numbers can be 3 or 4 or 5 or 6
Probability of rolling a number >2 = Probability of rolling 3 or 4 or 5 or 6
= P(3)+P(4)+P(5)+P(6)
= 1/6+1/6+1/6+1/6
=4/6
=2/3
Required probability = 2/3
Answer:
The interquartile range (IQR) is a measure of variability, based on dividing a data set into quartiles.
Step-by-step explanation:
Order the data from least to greatest
Find the median
Calculate the median of both the lower and upper half of the data
The IQR is the difference between the upper and lower medians
