6 kilometers is the greatest
60 meters is 6 decameters
600 centimeters is 6 meters
6000 millimeters is 6 meters
therefore kilometers is the greatest measurement here
Answer: 6x+4x +13x+6 equal
( pie over 2 - x)
Because we know that cos (pie over 2 ) =0 and sin (pie over 2) = 1
So we get
Sin (pie over 2 -x) =cos(x)
Answer:
5/7
Step-by-step explanation:
2/7 + 3/7
Denominator are equal so adding numerator,
(2+3)/7 = 5/7
The equation of the line of best fit is y = -0.03x + 69.94
<h3>How to determine the line of best fit?</h3>
The column headers are given as:
Year Time(s)
To enter the data values in a graphing calculator, we use the following representations:
x ⇒ Year
y ⇒ Time (s)
Using the above representations, we have the following calculation summary from a graphing calculator:
- Sum of X = 72209
- Sum of Y = 432.95
- Mean X = 1951.5946
- Mean Y = 11.7014
- Sum of squares (SSX) = 17242.9189
- Sum of products (SP) = -514.5997
The equation of the line of best fit is:
y = bx + a
Where
b = SP/SSX = -514.6/17242.92 = -0.02984 ≈ -0.03
a = MY - bMX = 11.7 - (-0.03*1951.59) = 69.94497 ≈ 69.94
So, we have:
y = -0.03x + 69.94
A linear equation is represented as:
y = Slope * x + y intercept
So, we have:
Slope = -0.03
y intercept = 69.94
The y-intercept implies that the initial time is 69.94 seconds, while the slope implies that the time decreases by 0.03 seconds each year
