Tanner cycled 8 miles in 20 minutes .What is the constant of proportionality based on the situation

solmaris [256]

The constant of proportionality based on the situation is 0.4

Step-by-step explanation:

Tanner cycled 8 miles in 20 minutes

We need to find the constant of proportionality based on the situation

1. The distance is proportion to the time, because the distance and

the time increased together

2. If the distance d and the time is t, then d ∝ t

3. The equation of the direct proportion is d = k t, where k is the

constant of proportionality

∵ d = k t

∵ d = 8 miles

∵ t = 20 minutes

- Substitute these values in the equation above

∴ 8 = k (20)

- Divide both sides by 20

∴ k = 0.4

The constant of proportionality based on the situation is 0.4

The average performance rating of the employees at Company A is 6.5 on a scale from 1 to 10 (10 being highest). The standard dev

djyliett [7]

Answer:

The best choice would be hiring a random employee from company A

Step-by-step explanation:

Supposing that the performance rating of employees follow approximately a normal distribution on both companies, we are interested in finding what percentage of employees of each company have a performance rating greater than 5.5 (which is the mean of the scale), when we measure them in terms of z-scores.

In order to do that we standardize the scores of both companies with respect to the mean 5.5 of ratings

The z-value corresponding to company A is

$z=\frac{\bar x-\mu}{s}$

where

$\bar x$ = mean of company A

$\mu$ = 5.5 (average of rating between 1 and 10)

s = standard deviation of company A

$z=\frac{\bar x-\mu}{s}=\frac{6.5-5.5}{2.1}=0.7142$

We do the same for company C

$z=\frac{\bar x-\mu}{s}=\frac{7.4-5.5}{6.8}=0.2794$

This means that 27.49% of employees of company C have a performance rating > 5.5, whereas 71.42% of employees of company B have a performance rating > 5.5.

So, the best choice would be hiring a random employee from company A

The symbol they are using is that of a ray so, order matters.

Ray BC is telling you the ray starts at point B like a line segment BUT continues on towards and through point C rather than stopping at it.

Ray CB is telling you just the opposite; the ray starts at point C, continues on towards and through point B.
