<h3>Question 1</h3>

One fourth of m minus six is equal to two times the sum of m and 9:

  • \dfrac{1}{4}m -6=2(m+9)

This is self-explanatory, please comment if something is unclear.

<h3>Question 2</h3>

Drew has 50 marbles; red, green and blue.

Equation for this:

  • r + g + b = 50

He has six more red marbles than blue marbles:

Equation for this:

  • r = b + 6

He has four fewer green marbles than blue marbles:

Equation for this:

  • g = b - 4

Substitute r and g into first equation and solve for b:

  • r + g + b = 50
  • b + 6 + b - 4 + b = 50
  • 3b + 2 = 50
  • 3b = 48
  • b = 48/3
  • b = 16

Drew has 16 blue marbles.

Snowcat [4.5K]

Answer:

Step-by-step explanation:

Variance is the sum of squares of all items x from mean.  i.e

Variance = \Sigma (x-xbar)^2

Being the sum of squares variance can never be negative irrespective of mean being negative.

Std deviation is the square root of variances.  This will thus be less than variance if variance >1 other wise std deviation will be bigger than variance.

Hence option d is right.
