Answer:

Step-by-step explanation:
The probability density function is :

With 0 < x < 3
To be a valid probability density function :

Where a < x < b
And also
f(x) ≥ 0 for a < x < b
Applying this to the probability density function of the exercise :





We can verify by replacing ''c'' in the original probability density function and integrating :


Also, f(x) ≥ 0 for 0 < x < 3
I'm hoping that a lot of people will come along on Brainly, see your questions, and give you as much help as you've been giving other people when you answered THEIR questions.
The total area of the garden is 97.5 square feet. 48.75 square feet of that space is planted with tomatoes, and the other 48.75 square feet is dedicated to cucumbers.
The road trip is 2916 miles long, if she wants to complete the trip in 6 days she will need to drive ___ miles per-day.
To figure this out we will need to divide 2,916 by 6 days
2,916/6 = 486 miles
Answer:
504 kilos de manzanas fueron llevados a la escuela.
Step-by-step explanation:
Sean
,
la cantidad de cajas de manzanas y peras, respectivamente. De acuerdo con el enunciado, tenemos el siguiente sistema de ecuaciones:
Total de cajas
(1)
Masa de cada caja de peras
(2)
(3)
Masa de caja de manzanas
(4)
De (2) en (3), tenemos que la masa de cada caja de peras es:

Por (4), encontramos que la masa de cada caja de manzanas es:


Finalmente, de (1) tenemos la cantidad de cajas de manzana:


La cantidad de kilos de manzanas llevada a la escuela se obtiene al multiplicar la cantidad de cajas de manzana por la masa de cada caja:


504 kilos de manzanas fueron llevados a la escuela.
