Answer:
-5
Step-by-step explanation:
4x - 1 = 6x + 9
4x = 6x + 10
-2x = 10
x = -5
Answer:
Tendrá que hacer 250.000 salidas para obtener 5 kilogramos de miel.
Step-by-step explanation:
Con la información proporcionada, puedes usar una regla de tres para calcular cuántas salidas tendrá que hacer para obtener 5 kilogramos de miel dado que las abejas tienen que hacer 50.000 salidas para obtener 1 kilogramo de miel:
1 kilogramo → 50.000 salidas
5 kilogramos → x
x=(5*50.000)/1
x=250.000
De acuerdo a esto, la respuesta es que tendrá que hacer 250.000 salidas para obtener 5 kilogramos de miel.
The graph represents the line x = 3.
Since there is more than one y-value for the one x-value provided, this graph is not a function.
The range is infinite, as there are no limits shown on the graph, and the slope is undefined.
The domain is only 3, since the only x-value on the graph is 3.
Based on this information, the statements that are true will be:
C. This graph is not a function because the value x = 3 is assigned to more than one y-value.
E. The equation of this line is x = 3.
(Note that D says the graph <em>is a function</em>. The graph isn't a function, as there is more than one y-value for x = 3.)
Answer: 600

Answer: Observational study
Step-by-step explanation:
The study illustrated in the question is an observational study. It is referred to as an observational study, because in this case, the price of the individual cereals us not being controlled by the students. They've no control over it.
If it was an experiment, there'll have been a control group and the students will have control over the price. Also, the sampling methods used here is a systematic random sampling.
