Answer:
- y = 0.937976x +12.765
- $12,765
- $31,524
- the cost increase each year
Step-by-step explanation:
1. For this sort of question a graphing calculator or spreadsheet are suitable tools. The attached shows the linear regression line to have the equation ...
... y = 0.937976x + 12.765
where x is years since 2000, and y is average tuition cost in thousands.
2. The y-intercept is the year-2000 tuition: $12,765.
3. Evaluating the formula for x=20 gives y ≈ 31.524, so the year-2020 tuition is expected to be $31,524.
4. The slope is the rate of change of tuition with respect to number of years. It is the average increase per year (in thousands). It amounts to about $938 per year.
5. [not a math question]
Answer:
$0.21 per year
Step-by-step explanation:
$0.21 times 5 years equals $1.05
So its $0.21
Answer:
y=mx+b
Step-by-step explanation:
C
First you -4 from x so you have to do the opposite which is to add 4
Answer:
38,660
Step-by-step explanation:
54 thousands 6 hundreds 12 tens – 15 thousands 8 hundreds 26 tens
54 thousands = 54000
6 hundreds = 600
12 ten = 12*10 = 120
54 thousands 6 hundreds 12 tens = 54000+600+120 = 54720
15 thousands = 15000
8 hundreds = 800
26 tens = 26*10 = 260
15 thousands 8 hundreds 26 tens = 15000+800+260 = 16060
Thus,
54 thousands 6 hundreds 12 tens – 15 thousands 8 hundreds 26 tens
= 54720- 16060 = 38,660 (Answer)
