Answer:
No
Step-by-step explanation:
Here we are taking only one measurement: the height of one person. Strictly speaking, this is NOT a statistical question.
"List the heights of a sample of 50 first-graders" would definitely be a stat. question.
So the ratios are 4 to 5 to 5 to 8 to 9 to 9
that means that the first 2 sides can be simplified to 4 to 5
therefor the whle sum is all the units added up
4+5+5+8+9+9=40
720=40 units
divide by 40
18=1 unit
solve for each unit
we have
4 units
5 units
8 units
9 units
4 times 18=72
5 times 18=90
8 times 18=144
9 times 18=152
the angles are
72,90,90,144,152,152
Answer:
3 months
Step-by-step explanation:
Let x be the number of months CDs are added at Tom and Nita's respective rates of 1 and 5 CDs/month.
Tom's collection after x months is = 30 + 1x
Nita's collection after x months is = 18 + 5x
At some point they will have equal numbers of CD's, so set the equations equal to each other:
30 + 1x = 18 + 5x
4x = 12
x = 3 months
At 3 months both Tom and Nita will have the same number of CDs.
Tom: 30 + 1*3 = 33 CDs
Nita: 18 + 5*3 = 33 CDs
