Okay, so you're going to go along the line that goes side to side, and then find positive 2. It'll be on the right side. From there, go half way in and insert a line going up and down.
Bam! You've got yourself x= 2.5 graphed!

Q1-(23.5) Q2(29) Q3(32.5)
Interquartile range= Q3-Q1=32.5-23.5=9
Answer:
Step-by-step explanation:
<u>Point slope form</u>
y=mx +c, where m is the gradient and c is the y-intercept.
To find the gradient, use the formula below:
Substitute the value of m into the equation
To find c, substitute a coordinate into the equation.
When x= -3, y=7,
Thus, the equation of the line is 
Answer:
The probability is 0.022
Step-by-step explanation:
Firstly, we need to get the total number of balls in the urn
mathematically, we have this as ;
8 + 9 = 17
now, the probability of selecting a white ball will be the number of white balls divided by the total number of balls
Mathematically, we have this as 9/17
Now, since the event is carried out with replacement, the probability for the six times is the same
So, we have the probability as;
(9/17)^6 = 0.022
Answer:
480
