Answer:
18 students are likely to be wearing red
Step-by-step explanation:
From the question, we know a student either wears red , or blue, with the probability of a student wearing red is 3 times more probable than wearing white.
So, let’s say out of the 24 students, x of them are wearing white. What this practically mean is that 3 * x = 3x of the students would be expected to be wearing red.
Now, adding the number of people wearing red and white together in terms of x, we have x + 3x = 4x
We equate this to 24; 4x = 24 and x = 24/4; x = 6
The number wearing red probably is 3 * x = 3 * 6 = 18 people
Answer:The answer is 3 equal -4
Step-by-step explanation:
Answer:
x=3.4 y=-5.8 (the steps are in order and I explained to the best of my ability)
Step-by-step explanation:
x+3y=-14 substitute the x for -14-3y in the second problem
x=-14-3y 2(-14-3y)-4y=30
-28-6y-4y=30
-10y=58
y=-5.8
substitute the y in the first equation for -5.8
x+3(-5.8)=-14
x-17.4=-14
x=3.4
