Answer:
75 boxes of standard varieties and 40 boxes of deluxe varieties.
Step-by-step explanation:
Let x be the number of standard variety and y be the number of the deluxe variety of the strawberry,
∵ Total number of strawberries = 115,
⇒ x + y = 115
⇒ x = 115 - y -----(1),
Total spending amount is $ 700, in which each standard variety costs $ 4 and deluxe variety costs $ 10,
⇒ 4x + 10y = 700 ----(2),
From equation (1),
4(115-y) + 10y = 700
460 - 4y + 10y = 700
460 + 6y = 700
6y = 240
⇒ y = 40
Again from equation (1),
x = 115 - 40 = 75
Hence, there are 75 boxes of standard varieties and 40 boxes of deluxe varieties.
Answer:
“A random variable is one whose values describe the outcome of some chance process”
Step-by-step explanation:
Roughly speaking, a random variable is a function whose values depend on outcomes of a random phenomenon.
The phenomenon could be an experiment created by human beings, a natural process or any other kind of event that produces results that cannot be foreseen with a deterministic model like a differential equation or formula of any kind.
<em>
The random variable must also be a measurable function. </em>
Since its value cannot be predicted in a deterministic way, we usually approximate its possible values with probabilistic measures.
So, from the possible choices of answer, the one that fits the best is
“A random variable is one whose values describe the outcome of some chance process”
They are equivalent. combine like terms on the first one and 9x-4x+25 can be simplified to 5x+25.
I’m going to go with Exponential
