In One hour a bakery sold five muffins and nine bagels for a total of $25.50 the next hour the bakery sold three muffins and 12

bagels for a total of $28.50 let M represent the price of one muffin and B represent the cost of one bagel Draco wrote the following system of linear equations to solve for the cost of each item.
5m+9b=28.50
3m+12b=25.50

What is Draco’s error?
A.) Draco should have set the first equation equal to 25.50 and the second equation equal to 28.50.
B.) Draco should have written the first equation as 3m+9b= 25.50.
C.) Draco should have written 9b in the second equation and 12b in the first equation.
D.) Draco should have written the second equation as 5m+12b=28.50.

Answer:

Option A is the correct choice.

Step-by-step explanation:  

We have been given the system of linear equations written by Draco. We are asked to find Draco's error.

Let us form a system of equations using our given information.

Let m represent the price of one muffin and b represent the cost of one bagel.

We are told that in one hour a bakery sold five muffins and nine bagels for a total of $25.50. We can represent this information in an equation as:

5m+9b=25.50...(1)

The next hour the bakery sold three muffins and 12 bagels for a total of $28.50. We can represent this information in an equation as:

3m+12b=28.50...(2)

Now let us see system of equations written by Draco.

5m+9b=28.50

3m+12b=25.50

We can see that Draco has set the price of 5 muffins and 9 bagels equal to $28.50, which is the price of 3 muffins and 12 bagels.

Therefore, Draco should have set the first equation equal to 25.50 and the second equation equal to 28.50. The correct choice is option A.

The most important characteristic of a sample that makes it possible to generalize the results of a research study to the popula
nlexa [21]

Answer:

C. The sample is carefully screened to ensure that it contains, proportionately, people with the same demographic profiles as encountered in the population.

Step-by-step explanation:

Sampling

This is a common statistics practice, when we want to study something from a population, we find a sample of this population.

When choosing a sample, you have to be careful, to avoid choosing a biased sample.

In this question:

Option A is not correct, as this wouldnt be representative of the entire population, since there is expected to be a significant number of people without these skills.

Option B is not correct, as we would not have a sample.

Option D is not correct, as a quickly selected sample could lead to bias.

Option E is not correct, as it could also lead to bias.

So the answer is given by option C.

Evaluate the piecewise function
Gelneren [198K]

Answer:

5

Step-by-step explanation:

f(4) falls into the category x > -1 because 4 > -1. Therefore, we use the function f(x) = 2x - 3. f(4) will then equal 2(4) - 3 = 5.
