Is 0.21 less or greater than half

Answers

Answer 1
Answer: 0.21 is less than half because a half is 0.5.

So 0.21 is less than 0.5 because the tenths place is less than 5 which makes 0.21 smaller than a half
Answer 2
Answer:


less than half because .5 is half of one

.5 = .50

compare the 2. that's what I do.

.50

.21

forget the decimal. and pretend that 100 = 1

Hope this helped

choosing five students each from seventh and eighth grade
choosing five female students and five male students

Answers

Answer:

Choosing ten students from a box that contains the names of the entire group

Step-by-step explanation:

If each and every unit has equal chance of being selected in a sample then it is called Random Sampling. Here choice of sample should be unbiased and independent.

Option (a) is incorrect because here selection of student is not independent as only those students are choosing who also participate in music class.

Option (b) is correct option as selection of students are independent and unbiased. Also here each student has equal chance of being selected in sample.

Option (c) can't be chosen as selection of student is done from particular cluster.

Option (d) is also incorrect as here we put condition of male and female students.

choosing ten students from a box that contains the names of the entire group.

This is the only one where everyone has an equal chance of being chosen.

a cereal box is 8 1/2 inches long, 3 1/2 inches wide, and 12 inches high. what is the volume of the the box?

Answers

Length of the cereal box = 8 1/2 inches
                                        = 17/2 inches
Width of the cereal box = 3 1/2 inches
                                      = 7/2 inches
Height of the cereal box = 12 inches
Then
Volume of the cereal box = Length * Width * Height
                                        = (17/2) * (7/2) * 12 cubic inches
                                        = 17 * 7 * 12 cubic inches
                                        = 1428 cubic inches
I think its 357 squared. Just multiply all of it together. I'd check the formula for finding volume if you want a reliable answer
