Answer:
2/3 + 2/3 + 1/3.
Step-by-step explanation:
You can use equivalent fractions. 6 is 2x more than <u>3</u>. You can use three as the denominator.
Answer:
2x+1y
Step-by-step explanation:
because a variable (the letter) is always 1, in that case 1 + 1 is 2 and 1 x 1 is 1. but since x and y are two different letters you cannot add them. hoped that helped :)
Answer:
The interquartile range is 5.
Step-by-step explanation:
Ah, a throwback to interquartile range... let me help :)
4,5,6,8,9,10,11,12
First, you need to know how to use the IQR. The interquartile range is basically known as the process of subtracting the upper quartile and the lower quartile of a set of data. The lower quartile should be written as Q1, and the upper quartile would be labeled as Q3. This would make the midpoint (median) data set Q2, and the highest possible point would be labeled Q4. Next, you have to always understand what you are looking at. For example, let's split the set 5,6,7,8,9,10,11,12 into groups. 5 and 6 would be Q1, 7 and 8 would be Q2, 9 and 10 would be Q3, and last but not least, 11 and 12 would be labeled as Q4. Now take Q1 and subtract it from Q3 and that is how you get your IQR.
Hello!
You can use the Pythagorean Theorem

c is the hypotenuse which is the side across the right angle
a and b are the other sides
Put in the values you know

Square the numbers

Subtract 25 from both sides

Take the square root of both sides
a = 10.9
The answer is D) 10.9 centimeters
Hope this helps!
