Answer: x = 1
Step-by-step explanation:
we have
x tetras
3 goldfish
5 platies.
the total number of fishh in the bowl is x + 3 + 5
The probability of removing a gold fish is equal to the number of gold fish divided by the total number of fish, this is:
p = 3/(x + 3 + 5) = 1/3
3 = (1/3)(x + 3 + 5) = x/3 + 1 + 5/3
9 = x + 3 + 5
x = 9 - 8 = 1
then wemust have that x = 1
because 1 + 3 + 5 = 9
and 3/9 = 1/3
Answer:
B. [3, 5]
Step-by-step explanation:
The range of a graph are the y-values that are plotted on the vertical axis (y-axis). In order words, the range values, are the possible set of output values of that are plotted on the vertical axis on the graph.
"[ ]" is usually used to denote the possible set of values.
Therefore, the range of the given graph, as we can see from the y-axis, include values from 3 to 5. Therefore, the range of the graph is [3, 5].
Answer:
I think the second table.
Step-by-step explanation:
Because it is the correct one.
Answer:
Step-by-step explanation:
The strange thing about the greatest integer function is that the number you are evaluating the function at is not actually the number unless its an integer. The rule is to round down, ALWAYS, if you are dealing with a value of x that is not an integer. In other words, you are NOT evaluating the function at 8.6, you have to round down to 8 and evaluate it there. 8 - 5 = 3
