Answer:
None of the options are correct, the correct answer is 1,050 boys and 350 girls.
Step-by-step explanation:
A ratio of 3:4 can be turned into a percentage by dividing 3 by 4. This would give us 0.75 or 75%. This means that the remaining 25% (100-75 = 25) are girls in this ratio. If there are 12 boys we can find the total amount by dividing 12 by 0.75 and then multiplying that answer by 0.25 (25%) in order to find the amount of girls in that ratio, like so...
12 * 0.75 = 16 total
16 * 0.25 = 4 girls
If there are a total of 1,400 students we can find how many are boys and how many are girls by simply multiplying by the percentages.
1,400 * 0.75 = 1,050 boys
1,400 * 0.25 = 350 girls.
Apparently, none of the options are correct, the correct answer is 1,050 boys and 350 girls.
Answer:
6 / 5 ( or ) 1.2
Step-by-step explanation:
5x = 6
x = 6 / 5
( or )
x = 1.2
Answer:
Unlikely = greater Than 0 ; less than
Likely = greater than 0.5 ; less than 1
Neither likely nor unlikely = 0.5
Step-by-step explanation:
Probability values usually range between standardized values between 0 and 1. With values closer to 1 depicting greater possibilities of an event. Probability value of zero means certain and probability value of 0 zero means.impossible.
Using this standardized values :
An unlikely event is more of not occurring than occurring (that is the event has higher chances of not happening) ;
Hence; We can categorize unliky events to range from below the mid value to greater Tha.n 0
Unlikely event : greater Than 0 ; less than 0.6
Events with probability above the mid value of 0.5 have higher chances of occurring (greater likelihood) hence, Probability is greater than 0.5 but less than 1.
Neither likely nor unlikely event will take the boundary point between likely and unlikely = 0.5
Answer:910
Step-by-step explanation: it rounds up because if the last number is more than 5 you round up
