5.291 to 2 d.p I think that is the answer.
The first task in such exercises is to order the data in ascending order.
201,218, 242, 257, 265, 275, 301.
The algorithm to find the first quartile of a distribution of discrete observations is: If the number of observations is odd;
Exclude the median. Then, the first quartile is the median of the lower half of the observations.
If the number of observations is even, take the median of the lower half of observations immediately.
Here, we have 7 observations. The median is 257 and the observations below it are 201,218,242. The median of this is 218. Thus, 218 is the first quartile. (Similarly, 275 is the 3rd quartile).
Answer 36
Do the parentheses first (3^2)=9
(9)4•1
The 1 is because 3^0 is just 1
9•4 is 36 and 36•1 is 36.
(If you are)- Solving The Equation
1. Multiply both sides by eight over three
8/3•1/2 = 8/3•3/8 which gives you 4/3.
2. Swap the sides of the equation
4/3=y turns into y= 4/3 and that’s your answer. (y=4/3).
(Or if you’re working on)- Rewrite In Standard Form
Swap 1/2 and 3/8y , so it should be 3/8y=1/2.
Then multiply both sides by 8/3, and that should give you y=4/3.
Then multiply both sides of the equation by 3, and that should give you 3y = 4. And 3y=4 would be your answer.
Hope these helped! :)
