Answer:
1. answer is the first one "See you!"
2. answer to the second one is "como se dice"
3. answer for the third one is "canyon"
the equation is in x-terms, meaning is a vertical parabola, and therefore the axis of symmetry will be the x-coordinate of the vertex, namely x = -1.
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.
Answer:
50+30z=250+10z
z=10
Step-by-step explanation:
50+30z=250+10z
Substract 50 on both sides
50+30z-50=250+10z-50
Simplify
30z=10z+200
Substract 10z on both sides
30z-10z=10z+200-10z
20z=200
200/20 = 10
Answer z=10
