Answer:
40
Step-by-step explanation:
you have to multiply x by 4 to get y when x=4 and y=16. so if x=10, then you have to multiply what x is (10) by 4 because there is a common ratio.
hope this helps!! please give brainliest!!!!!!
If William has 195 marbles, let's find 4/5 of that.
195 * 4/5 = 156
156 is 2/5 of the marbles Daniel has.
Now we must multiply by the reciprocal
156 * 5/2 ( to find all of Daniel's marbles, not just 2/5) = 390 marbles
Daniel has 390 marbles.
Answer:
Step-by-step explanation:
red balls=3
blue balls=4
total balls=3+4=7
probability of selecting 3 red balls=3/7 ×2/6×1/5=1/35
selecting 1 red ball=3/7
after selecting there are two red balls and total balls are 6
so now P=2/6
and so on .
Answer:
1/3
Step-by-step explanation:
120/360 = 12/36 = 2/6 = 1/3
Answer:
A function is a relation that maps inputs from a set called the domain, into outputs from a set called the range.
Such that each input can be mapped into only one output.
So for example, if we have a relation that maps the input 2 into two different values:
f(2) = 4
f(2) = 8
Then this is not a function.
In the case of the problem, we have a student as the input, and the hair color as the output.
So we will have something like:
f(student) = blond
And if this student decides to change his/her hair color to red?
Then the function becomes:
f(student) = red
So for the same input, we had two different outputs, which means that this is not a function.
We also could have the case where a given student has two colors (Californian for example)
Where again, we would see two different outputs for one single input.
