Set B:{44, 13, 24, 12, 56}

has a greater spread because

Answers

Answer 1

Answer:

Answer: B has greater spread than A.

Step-by-step explanation:

Since we have given that

Set A: {38, 12, 23, 48, 55, 16, 18}

Range of A = Highest - Lowest

Range of A = 55 - 12

Range of A = 43

Set B:{44, 13, 24, 12, 56}

Range of B = Highest - Lowest

Range of B = 56 - 12

Range of B = 44

Since Range of B is more than range of A.

Hence, B has greater spread than A.

Subtract: (2x3+7x2−4)−(2x2+4x−10)

Answers

Answer:

-102

Step-by-step explanation:

2x3=6

6+7 = 13

13x2=26

26-4=22

2x2=4

4+4=8

8x-10=-80

-80 - 22 = -102

Hope this helps

Final answer:

To subtract the given expressions, first, simplify each expression separately by combining like terms. Then subtract the second expression from the first expression by distributing a negative sign and adding it to the first expression.

Explanation:

To subtract the given expressions, (2x^3+7x^2-4) - (2x^2+4x-10), we need to simplify each expression separately and then subtract them. First, combine like terms within each expression. Then, subtract the terms of the second expression from the first expression. This can be done by distributing a negative sign to each term in the second expression and then adding it to the first expression.

So, (2x^3+7x^2-4) - (2x^2+4x-10) = 2x^3+7x^2-4 - 2x^2-4x+10.

Combining like terms, we get 2x^3+(7x^2-2x^2)+(-4-4x)+(10). Simplifying further, we have 2x^3 + 5x^2 - 4x + 6. Therefore, the result of the subtraction is 2x^3 + 5x^2 - 4x + 6.

maya wants to mark a length of 7 inches on a sheet of paper, but she does not have a ruler . she has pieces of wood that are 4 inches 5 inches, and 6 inches long. Explain how she can use these pieces to mark a length of 7 inches.

Answers

ok
6+1=7
if only we could find 1
hmm

4+1=5
so mark a starting line
put the 4 inch and 5 inch wood at that line, facing the same direction (lying flat on paper)
the difference between the pieces of wood is 1 inch
mark the end of the 5 inch and the end of the 4 inch
that is 1 inch
now pick either end of that 1 inch mark and measure 6 inches more

Miguel's teacher asks him to color 4/8 of his grid. He must use 3 colors; red, blue, green. There must be more green sections than red sections. How can Miguel color the sections of his grid to follow all the rules?

Answers

One correct answer is:

2/8 green, 1/8 red, and 1/8 blue.

Explanation:

If there are 8 tiles, coloring 4/8 means coloring 4 tiles. Using those three colors, we could use each 1 time with 1 left over. Since we must have more green, we would use it twice; this would give us 2 green, 1 red and 1 blue.

Since the grid is not necessarily 8 squares, we must account for this by saying 2/8 green, 1/8 red and 1/8 blue.

1/8 red 1/8 blue 1/8 green and another 18 green 1/8+ 1/8+1/8+1/8=4/8
