(1) the probability of that happening is .4444.. so on. the jar isnt 25% red balls because 25% of 36 is only 9 and he pulled out 16 red balls.

Suppose 56% of students chose to study Spanish their senior year, and that meant that there were 98 such students. How many stud
Varvara68 [4.7K]

The number of students who chose not to study Spanish in their senior year is 124.

In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.

Given that

56% Students studied Spanish, which means 44% did not study Spanish.

In mathematics, a ratio shows how many times one number contains another.

Hence if the ratio is:

56 : 44 = 14:11

Then, the number of students who did not study Spanish is:

(14/11)×98 = 124.

Therefore the correct answer is 124.

14,345,678 (nearest hundred thousand) * what’s is the answers
Readme [11.4K]

Answer:

14,300,000

Step-by-step explanation:

Starting off with 14 million, you haven't reached the 100 thousands or below yet where you should start. The next digit, 3, is in the 100 thousands place and the digit next to it is four. When you're rounding, if the digit is greater than five, then you round up. (example: if the number you're rounding is 67, seven is greater than five so you would round it to 70.) If the digit you are rounding is smaller than 5 then you would round down. (Example: if the number you're rounding is 34, then you would round down because four is smaller than five or higher.) Since in your problem, you have 345,678, (we've already discussed the 14 million part in the beginning) 4 is smaller than 5 or higher so it would round 14,345,678 to 14,300,678. However, since we've already rounded the part we meant to do, every digit after would turn to 0. The final result would be 14,300,000.
