Answer:

Small boxes: 8

Large boxes: 11

Step-by-step explanation:

number of small boxes = x

number of large boxes = y

weight of boxes is represented by:

50x + 80y = 1280

Number of boxes is represented by:

x + y = 19

First, we'll solve for x in terms of y:

x = 19-y

Then we'll substitute that into the weight equation

50(19-y) + 80y = 1280

950 - 50y + 80y = 1280

30y = 330

y = 11

Now drop that numerical value into the number of boxes equation, and we'll get

x + 11 = 19

x = 8

Check the math in the weight equation:

50(8) + 80(11) =

400 + 880 = 1280

Let me know if you have any questions. Have a good evening!

Determine whether the relationship between the circumfrance of a circle and its diameter is a direct variation. If so, identify

kipiarov [429]

Answer:

The relationship between the circumference of a circle and its diameter represent a direct variation and the constant of proportionality is equal to the constant $\pi$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y=kx$

where K is the constant of proportionality

In this problem we know that

The circumference of a circle is equal to

$C=\pi D$

therefore

the relationship between the circumference of a circle and its diameter is a direct variation and the constant of proportionality is equal to the constant $\pi$

In a study of all babies born at hospitals in one state, it was found that the average (mean) weight at birth was 3197.4 grams.

Effectus [21]

An experiment value can either represent statistic or parameter

The value of the average (mean) weight at birth represents is parameter

<h3>How to determine if the value is statistic or parameter</h3>

The mean value is given as:

$Mean = 3197.4$

From the question, we understand that the value represents the average weight at birth of all babies born at hospitals in one state

The keyword "all" means that the value represents parameter

Hence, the value of the average (mean) weight at birth represents is parameter
