Answer:
y=-3/2x-7
Step-by-step explanation:
the question in English
Juan has blue cubes with a 55 mm edge and red cubes with a 45 mm edge. He stacks them in two columns, one of each color; he wants the two columns to be the same height. How many cubes does he need, as a minimum, of each color?
Let
x---------> the number of blue cubes
y--------> the number of red cubes
we know that
Juan wants that the two columns to be the same height
so
solve for y
I proceed to calculate a table, assuming values of x to calculate the value of y. When the values of x and y are whole numbers, I will have found the solution.
the table in the attached figure
therefore
<u>the answer is</u>
9 blue cubes
11 red cubes
The probability of getting an S on the first draw and then a T on the second draw is 2/12 if the bowl contains 9 marbles with letters on them.
<h3>What is probability?</h3>
It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.
Probability of getting letter an S:
P(S) = 3/9
Probability of getting letter an T:
P(T) = 2/8 (without replacement)
P(S, T) = (3/9)(2/8)
P(S, T) = 6/72 = 2/12
Thus, the probability of getting an S on the first draw and then a T on the second draw is 2/12 if the bowl contains 9 marbles with letters on them.
