What are the lower and upper quartiles of this data 122,164,71,98,84,147,114,111,98,85,104,71,77
RSB [31]
Lower quartile = 80.5
Upper quartile = 118
Answer:
x = 18
Step-by-step explanation:
The parts of the triangles are proportional, so you can write ...
2x/80 = 27/60
Multiply by 120:
3x = 54
Divide by 3:
x = 18
Answer:

Step-by-step explanation:
Factor the expression by first finding a GCF. Each term has the y variable and this can be pulled out as the GCF.

To further factor the expression break the polynomial into two binomials.
To factor into two binomials, find factors that multiply to -5 and add to -4.
-5 and 1 are factors and these make the binomials
.
The final factorization is 
Answer:
3/4
Step-by-step explanation:
12/16 can be simplified just divide by 4
