Looking at the number line, it is visible that the circular marks at the ends of the shaded region are shaded as well, not empty. This indicates that the values that these marks lie on, 55 and 65, must be included in the range. The only option that fits this is A, a temperature range within 5 degrees of 60 degrees Farenheit<span>.
This is because 5 degrees less than 60 degrees is 55, while 5 degrees greater than 60 is 65 degrees.</span>
a. The table represents a proportional relationship
b. The constant of proportionality is 5/6
<h3 /><h3 /><h3>Proportional relationship:</h3>
Proportional relationship are relationship between variable where their ratios are equivalent. The variables in our case are total weight(pounds) and number of books.
Therefore, let's check if the table represent a proportional relationship.
let
total weight = x
number of book = y
k = constant of proportionality
y = kx
10 = k12
k = 10 / 12 = 5 / 6
y = kx
15 = 18k
k = 15 / 18
k = 5 / 6
y = kx
25 = 30k
k = 25 / 30
k = 5 / 6
y = kx
50 = k60
k = 50/60 = 5 / 6
The constant of proportionality is the same. Therefore, the table represents a proportional relationship
The constant of proportionality(k) is 5/6.
