The appropriate response is a weighted average. It is a mean ascertained by giving qualities in an informational index more impact as indicated by some characteristic of the information. It is normal in which every amount to have arrived at the midpoint of is allocated a weight, and these weightings decide the relative significance of every amount on the normal.
Answer:
A linear formula for S as a function of D is S=17D+1534
Step-by-step explanation:
We are supposed to find a linear formula for S as a function of D.
Equation of line : y = mx+c
We are given that At the surface, the speed of sound is 1534 meters per second.
c = 1534
We are given that for each increase in depth by 1 km, the speed increases by 17 m/s
So, Slope = m = 17
Substitute the values in equation
y=17x+1534
x denotes depth
y denotes speed
We are given that Use D for depth and S for the speed of sound
So, S=17D+1534
Hence a linear formula for S as a function of D is S=17D+1534
The scale factor is what u multiply the first image by to get the second image. So by dividing the second image by the first image will give u the scale factor.
6 / 1.5 = 4....so there is a scale factor of 4 because 1.5 * 4 = 6
Answer:
A) x=6
Step-by-step explanation:
6.5^2-2.5^2=x^2
42.25-6.25=x^2=36
x=6
Answer:
