Plzzz its due 13points

a researcher observes and records the height of a weight moving up and down on the end of a spring. at the beginning of the observation the weight was at its highest point. from its resting position, it takes 20 seconds for the weight to reach its highest position, fall to its lowest position, and return to its resting position. the difference between the lowest and the highest points is 6 in. assume the resting position is at y = 0.

use the sine tool to graph the function. the first point must be on the midline and the second point must be a maximum or minimum value on the graph closest to the first point.

First, second and third points are (0, 0), (5, 3) and (15, -3).

Step-by-step explanation:

In this question we have to draw a sine graph with the parameters

Amplitude a = 6/2 =3

resting position is y = 0 means there is no horizontal and vertical shift.Curve starts from the origin (0, 0).

Time t taken from rest position to maximum, then from maximum to minimum and then to rest position = 20 seconds

So period = 20 seconds

b = 2π/period = 2π/20 = π/10

c = 0 and d= 0

Now we write the equation of sine curve.

y = asin(bx + c) + d

y = 3sin(πt/10 +0) + 0

y = 3sin(πt/10)

So the the points are (0, 0), (5, 3),(15, -3).

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

the football players are volunteering for the test.
