Answer: A. Paul’s data has a bigger overall spread than Sally’s data
The range of Paul’s Data: 28-12=16
The range of Sally’s Data: 30-15=15
16>15. Therefore Paul’s data has a bigger overall spread than Sally’s
Why B is wrong: Remember that the interquartile range is the “box” range.
Paul’s IQR: 26-15=11
Sally’s IQR: 28-18=10
11<10 is false, so B is false.
Why C and D is wrong: The middle line in the IQR represented in each box and whisker plot is the median. Paul’s median is not equal nor greater than Sally’s median. 18=24 18<24 is false. Therefore, C and D are false.
Hello! And thank you for your question!
First to make the question more easy to understand. We are going to make these three fractions improper fractions.
To do this I will give an example. 3 1/6. Do 6*3+1=19/6
Equation after made improper:
19/6 + 74/9 - 3/2
Now that we have this we can find the answer!
-------------------------------------
Work:
First you are going to find the LCD. And change all the numbers denominators to that LCD.
LCD = 18
Equation After incorporating LCD:
57/18 + 148/18 - 27/18
Second we are going to add all of the numerators together to get:
178/18.
Then simplify 178/18 to get:
89/9
Then convert 89/9 to a mixed fraction:
9 8/9
Final Answer:
9 8/9
We can write this in algebraic terms as:
16+8x = 24+6x
so
2x = 8
x = 4
The number is 4.
Answer: 336.80 miles, North of east
Step-by-step explanation:
Given
Plane lands at a point 324 miles east and 92 miles north
Distance is given by using Pythagoras theorem
Direction is given by using figure i.e.
Direction is North of east
That is a X and Y coordinate plane, in this case, they are labeled as an A and B coordinate plane. (where A is X in a regular plane and B is Y in a regular plane).
In the direction of A, the rule is to add 2 each time.
In the direction of B, the rule is to add 3 each time.
