All of the attendees at a symposium are either phys-
icists or biologists. If there are 123 physicists and
270 biologists, then how many additional physicists
must arrive at the symposium in order for the ratio
of physicists to total attendees to become 2 to 5?
Answer:
The number of additional physicist that must arrive are;
59 physicists
Explanation:
A ratio in mathematics is an indication of the number of times one quantity is larger than another quantity, that is the number of times a number of an item is found the number of another item
The given parameters of the attendees at the symposium are;
The number of physicists at the symposium, p = 123 physicists
The number of biologists at the symposium, b = 270 biologists
The total number of attendees at the symposium, T = 123 + 270 = 393 attendees
Let 'x' represent the expected number of physicist at the symposium
For the ratio of physicists to the total attendees to become 2:5, we have;
x/Tₓ = 2/5
Where;
Tₓ = The expected total number of attendees at the symposium = x + 273
∴ x = (2/5) × Tₓ = (2/5) × (x + 273)
x = (2/5) × (x + 273) = 2·x/5 + 2×273/5
x - 2·x/5 = 2×273/5
3·x/5 = 2×273/5
3·x = 546
x = 546/3 = 182
The expected number of physicist at the symposium, x = 182 physicist
The number of additional physicist that must arrive = x - p
∴ The number of additional physicist that must arrive = 182 - 123 = 59
The number of additional physicist that must arrive = 59 physicists
[30 Points] Answer this question! Please provide why this is the answer don't just put the answer tell me with a reason. Just for those clowns who think they are smart enough to put the incorrect answer or put whatever or steal it, I'm going to report the false comment and my points will return to me and you will have no points that you stole from me. ( ANSWER CHOICE IS IN THE SCREENSHOT Thank you for helping me out)
Answer:
A
Explanation:
A doesn't provide any measurable or provable evidence or information. All the other answer choices include measurable data and is "new" and thus also disproving/ challenging previous information. Answer choices B C D are claims that can be tested in an experiment too.
