Answer:
134
Step-by-step explanation:
268/2=134
since its equal both rows should have the same number.
there are some typos so I think that you need to multiply 7 by 2 because it said two-weeks 7 days in a week.so then it equals 14. multiply 14 by 37 you can get 518 days probably.
In the equation model, the simple harmonic motion is d=6sin(πt/4)-6 if the object moves in simple harmonic motion with a period of 8 seconds and amplitude of 6 cm.
<h3>What is simple harmonic motion?</h3>
Simple Harmonic Motion is described as a motion in which the restoring force is proportionate to the body's displacement from its mean position.
We have:
Amplitude A = 6 cm
Time period = 8 seconds
T = 2π/w
8 = 2π/w
w = π/4
Its displacement d from rest is -6 cm, and initially, it moves in a positive direction.
d(0) = -6 cm at t = 0
The equation becomes:
Thus, in the equation model, the simple harmonic motion is d=6sin(πt/4)-6 if the object moves in simple harmonic motion with a period of 8 seconds and amplitude of 6 cm.

Answer:
Part A) The 15th percentile of the head circumference of males 3 to 5 months of age in a certain city is 41.5 cm.
Percentile : A data item is said to be in nth percentile of distribution if n% of the distribution are less than that particular data item.
So,<u> by definition</u> we can say that the given statement means that 15% of males of 3 to 5 months of age have a head circumference less than or equal to 41. 5 cm
Part B ) The 90th percentile of the waist circumference of females 2 years of age in a certain city is 52.7 cm.
Percentile : A data item is said to be in nth percentile of distribution if n% of the distribution are less than that particular data item.
So,<u> by definition </u>we can say that the given statement means that The 90th percentile means that 90% of females of 2 years of age have less than or equal to 52.7 cm for their waist circumference
