Answer:
112/125
Step-by-step explanation:
If we know all 25 are in at least one foreign language class then we can assume that exactly 4 of the 18 kids in French only take French to add up to 25 and this means that the 14 left take both classes. Now we can create three fractions for each case which are 7/25 (Spanish only) 4/25 (French only) and 14/25 (Both) and we can know say that if he goes down the route of getting a Spanish only as his first he needs one of the 18 other students the chances of this happening are 7/25 * 18/25 = 126/625 the same thing is done with the French only and we get 4/25 * 21/25 = 84/625 and then we have the possibility of just getting a student that does both which is 14/25 or 350/625. now we add them all together to get 560/625 which is simplified to 112/125.
Hope this helps please mark brainliest :)
Rounding to the nearest million is just looking at the 100,000's place, and seeing if it's bigger than 5 or not. if it is you round to the number up to the next million and if it's not you round the number down to to the same million. In your case it rounds up to 2,000,000 because of the the 100,000's place is a 5 so you round up
The answer should be B because if she wants to make more than $120 she has to sell more than 8 dozens. The circle isn’t shaded because shaded means “more than or equal to” and since since she wants more than 120 instead of 120 or more the circle is open.
