Answer:

For the function

y = cos(1/2 x)

The x-intercept can be calculated by equating the function to zero and solving for x. So,

y = cos(1/2 x) = 0

1/2 x = arc cos 0

1/2 x = 90° +180°n

x =2 (90° +180°n)

x = 180° + 360°n

or converting to radians

x = (180° + 360° n)(π/180°)

x = π + 2π n

where n is any whole number

if n = 0

x = π

Therefore, the x-intercept is π or π+2π n

1. A bag contains rubber bands with lengths that are normally distributed with a mean of 6 cm of length, and a standard deviatio
romanna [79]
Roughly 1.7 percent of the bands are shorter than 3cm. We calculate the z score of the data point in standard distribution. By definition of z score, we use score minus mean divided by standard deviation. z=(3-6)/1.5=-2. A z score of -2 corresponds to approximately 1.7%, in other words, roughly 1.7 percent of data is less than 3cm.

Which equation represents a proportional relationship between the x and y values?
allochka39001 [22]

Answer:

y = kx

Step-by-step explanation:

We have to write an equation that states that the relationship between x and y is proportional.

Since x and y are proportional, so we can write symbolically  

y ∝ x

⇒ y = kx {Where k is the constant of proportionality}

So, this is the required equation. (Answer)

Geometrically it signifies that it is a straight line having constant slope k and it passes through the origin.
