Answer:

The middle answer

Step-by-step explanation:

Because if you did 4 x 10 - 10 that would give you 30

but if you did

3 x (44 - 3 x (6 + 6)) that would give you 1476 so the middle answer is correct

In Mr. Harold's class there are 12 students. They each have 5 pencils. Some of the students, s, each lost 2 pencils. Now, the st

The answer would be C. (12 x 5) - (s x 2) = 38.

This is because if there are 12 students with 5 pencils per student, we can say 12 x 5. Then, think of the phrase, two pencils lost per student. That would be 2s, or (s x 2). Since it’s lost, we would subtract that amount from 12 x 5.

A bag has 2 blue marbles, 3 red marbles, and 5 white marbles. Which events have a probability greater than 5? Select three

zhannawk [14.2K]

Answer:

Events 2,4 and 5 have probabilities greater than 0.5

Step-by-step explanation:

They are 10 balls combined: 2blue, 3 red and 5 white with the probabilities:

$P(red)=3/10=0.3\\\\P(white)=5/10=0.5\\\\P(blue)=2/10=0.2$

#We calculate the probabilities to check which events have a probability greater than 1/5=0.2

#choosing 1 blue marble

$P(1 \ blue)=2/10=0.2\\\\0.2=0.2$

#choosing 1 red marble

$P(red)=3/10=0.3\\\\0.3>0.2$

#choosing 1 red marble, not replacing it,

$P(red)=0.3\\\\P(blue,no \ replacemnet)=2/9\\\\P(red \ then \ blue)=0.3\times 2/9=0.067\\\\0.067$

#choosing 1 white marble, replacing it, and choosing another white marble

$P(white)=0.5\\P(white, no \ replacement \ in \ i)=4/9\\\\p_t=0.5\times 4/9=0.22\\\\0.22>0.2$

#choosing 1 white marble

$P(white)=5/10\\\\=0.5$

Hence, from our calculations, events 2,4 and 5 have probabilities greater than 0.5
