Which correlation coefficient will most likely describe the relationship between frequency of teeth brushing and the number of c
abruzzese [7]

Answer:

The correct approach is "-62". A further explanation is described below.

Explanation:

  • A dependent variable could be seen since the blackheads become triggered whenever some substance or material is deposited between some of the teeth.
  • Humans don't brush their teeth frequently, but there is still a significant possibility of decay, so cavities differ depending upon whether the specific teeth become brushed.

I JUST NEED THESE 3 QUESTIONS
Sidana [21]

Answer:  

 

1.     What is the period and the amplitude of the sine function representing the position of the band members as they begin to play?

Answer:  Amplitude is 80 ft, period is 60 ft.

 

2.     Edna is sitting in the stands and is facing Darla. Edna observes that sine curve begins by increasing at the far left of the field. What is the equation of the sine function representing the position of band members as they begin to play?

Answer:  y = 80cos(x*π/30)+80

 

3.     As the band begins to play, band members move away from the edges, and the curve reverses so that the function begins at the far left by decreasing. Darla does not move. The sine curve is now half as tall as it was originally. What is the equation of the sine curve representing the position of the band members after these changes?

Answer: y = 40cos(x*π/30)+80

 

4.     Next, the entire band moves closer to the edge of the football field so that the sine curve is in the lower half of the football field from Edna’s vantage point. What is the equation of the sine curve representing the position of the band members after these changes?

Answer:  y = 40cos(x*π/30)+40

VikaD [51]

Answer:

$24.04

Step-by-step explanation:

3 x $16.99 = $50.97

1 x $24.99 = $24.99

$24.99 + $50.97 = $75.96

$100 - $75.96 = $24.04
