The answer is 3. 1/3(x-5)= -2/3. Multiply by 3 on both sides. Add five and you get 3
Answer:
Step-by-step explanation:
<u>Given data:</u>
- <u>x | 2 | 3 | 4 | 5 | 6 </u>
- y | 21 | 69 | 261 | 1029 | 4101
<u>Logarithms of y-values:</u>
- log 21 = 1.322
- log 69 = 1.839
- log 261 = 2.417
- log 1029 = 3.012
- log 4101 = 3.613
<u>The ordered pairs:</u>
- (2, 1.322), (3, 1.839), (4, 2.417), (5,3.012), (6, 3.613)
<u>Using an online calculator found the equation of the regression line:</u>
<u>In our case it is:</u>
<span>4×2-z=7
⇒ 8 - z = 7
⇒ 8 - 7 = z
⇒ 1 = z
