The correlation coefficient for the costs and sizes of storage container is 0.55. How
are the costs and sizes of the containers related?

Answers

Answer:

There is a positive correlation between both variables.

Step-by-step explanation: That is to say, the relation between the cost and the size of the storage containers is growing.

As the size of the container increases the cost also increases.

The closer the correlation coefficient is to 1, the stronger is the positive relationship between the variables, in this case r = 0.52, so it could be concluded that the relationship between the variables is a medium positive correlation

A correlation coefficient is a statistical measure of the degree to which changes to the value of one variable predict changes to the value of another.

The costs and sizes of the containers are moderately correlated.

What is a correlation coefficient?

A correlation coefficient is a statistical measure of the degree to which changes to the value of one variable predict changes to the value of another.

We have,

The correlation coefficient for the costs and sizes of the storage container is 0.55.

We know that,

Correlation coefficients whose magnitude is between 0.5 and 0.7 indicate that the variables are moderately correlated.

Correlation coefficients whose magnitude is between 0.3 and 0.5 indicate that the variables are a low correlation.

Since the correlation coefficient for the costs and sizes of the storage container is 0.55, it is between 0.5 and 0.7.
So it is moderately correlated.

Thus the costs and sizes of the containers are moderately correlated.

Bill has $50 to spend on 2 birthday presents for his friends. If he spends $2.50 each for birthday cards, what is the range of money he can spend on each gift? Write and solve an inequality.

Answers

The inequality 2.50x + 2y ≤ 50 shows the situation that Bill has  $50 to spend on 2 birthday presents for his friends.

What is inequality?

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have:

Bill has $50 to spend on 2 birthday presents for his friends. If he spends $2.50 each on birthday cards.

Let's suppose the number of birthday cards is x and the cost of each gift is y.

Then the total cost for birthday cards = 2.50x

Total budget = $50

Total expense = 2.50x + 2y

2.50x + 2y ≤ 50

The above inequality represents the situation.

In the graph, the range of the solutions is shown.

Thus, the inequality 2.50x + 2y ≤ 50 shows the situation that Bill has  $50 to spend on 2 birthday presents for his friends.
