Answer:

scale factor = 2

Step-by-step explanation:

Since the dimensions have been doubled this is equivalent to multiplying the original dimensions by 2, that is

scale factor = 2

A circle has a radius of 555 inches (\text{in})(in)(, start text, i, n, end text, )and a central angle that intercepts an arc wi
leva [86]

Answer:

Central angle = 0.0003π

Step-by-step explanation:

Radius of circle = r = 555 in = 14.097 m

Arc length = s = 30 in = 0.762 m

Using formula

s=r\theta\\\\\theta=\frac{s}{r}\\\\\theta=\frac{0.762}{14.097}\\\\\theta=0.05408

Converting θ to radians

\theta=0.05408\frac{\pi}{180}\\\\\theta=0.0003\pi

A very large data set (N &gt; 10,000) has a mean value of 2.06 units and a standard deviation of 55.85 units. Determine the rang
butalik [34]

Answer:

 So in range "-35.6108 to 39.73"; 50% data set can be found

ux = 37.6704 unites

Step-by-step explanation:

Step One: State the given parameters

From the question we are given that

mean Ц =2.06 unites

Standard deviation б is  = 55.85 unites  

Probability density  → Normal

Let assume that it is symmetrically distributed about the mean

Step Two: Determine the range of the values

Our goal is to determine the range of values in which 50% of the data set should be found . Assuming that the range is from x_{1} to x_{2} and between these these we found 50% data set Hence from 0 up to x_{1} we found 25% and up to x_{2}  we found 75% of the data set therefore z value corresponding to x_{1} is - 0.6745 and the the z value corresponding to x_{2} is +0.6745 (Refer to the z-table for normal distribution) as shown o the diagram on the first uploaded image

The formula for  z is

                    z = \frac{x-mean}{standard deviation}

for x_{1} ,z = - 0.6745 ,substituting into the formula

               -0.6745 = \frac{x_{1}-2.06}{55.85}

 => -37.67 =  x_{1} -2.06

=> x_{1} =  -35.6108 unites  

for x_{2}  , z = 0.6745 , substituting into the formula

            0.6745 = \frac{x_{2}-2.06}{55.85}

=> 37.67 =  x_{2}  -2.06

=>  x_{2}  = 39.73 units

 So in range "-35.6108 to 39.73"; 50% data set can be found

ux = (39.73  -   (-35.73) )/2

   = 37.6704 unites

The unit rate that corresponds to the proportional relationship shown in the given graph above is: 4/3 cm/s.

<h3>How to Find the Unit Rate of a Proportional Graph?</h3>

The unit rate of a proportional graph is determined using the formula below:

k = y/x, where x and y are coordinates of any point on the line.

Thus, to find the unit rate of a proportional graph, pick the coordinates of any point on the line and find k = y/x.

From the given graph, let's pick the indicated point on the line having the coordinates, (12,16). Find k:

Unit rate (k) = 16/12

Simplify

Unit rate (k) = 4/3

Therefore, the unit rate that corresponds to the proportional relationship shown in the given graph above is: 4/3 cm/s.
