B is actually the correct answer i just took the test and got it right
Answer:
a)- Given that a student is a 10th grader, there is a 14% chance he or she has a job.
Step-by-step explanation:
Option (a) is correct here because Relative frequency means the probability of occurrence or number of time-specific event occurs to the total event.
Option (b) is not correct because We already know that student is in 10th or 11th grade, after that we get to know about 14% chance.
Option (c) & (d) are clearly not possible.
I'm pretty sure the slope is: - 4/11
49/100 is equal to .49 in decimal form, and now we just need to add the 4 wholes. This is equal to 4.49
Answer:
selecting one item? If you mean each color:
40% chance for a red marble / 2/5 chance
60% chance for a blue marble / 3/5 chance
Step-by-step explanation:
Because there are 12 blue marbles and 8 red marbles, we would total them to see how many marbles there are in total. There are 20 in total, but to find the probability, if we put all 20 marbles in a bag (blue and red), and we picked a marble at random, there are 8 red marbles and 12 blue marble in that bag. The probability that I will choose red marbles is 8/20 (or 8 red marbles out of 20 total marbles), and for blue marbles, it would be 12/20 (or 12 blue marbles out of 20 total marbles). Simplify both expression to 2/5, and 3/5 respectively. Finally, if you need percentage, just multiply the denominator by 5 to get it to a hundred, and do the same to the numerator. This way you don't change the value of the expression.
