Answer:

32 - 4x = 12

Step-by-step explanation:

Substitute x = 5 into the equations and compare:

18 - 2x = 18 - (2 x 5) = 18 - 10 = 8    incorrect

32 - 4x = 32 - (4 x 5) = 32 - 20 = 12  correct

11 + 6x = 11 + (6 x 5) = 11 + 30 = 41  incorrect

25x + 4 = (25 x 5) + 4 = 125 + 4 = 129  incorrect

x^5+5=(5^5)+5=25+5=30  incorrect

3x + 1 = (3 x 5) + 1 = 15 + 1 = 16  incorrect

when 9 is increased by 3x the result is greater than 36. What is the least possible interger value for x?
arsen [322]

Answer:

10

Step-by-step explanation:

"When 9 is increased by 3x"

THis means 9 + 3x

"The result is greater than 36"

We use greater than sign and 36

So we can write:

9 + 3x > 36

SOlving this via equation rules and algebra:

9 + 3x > 36

3x > 36 - 9

3x > 27

x > 27/3

x > 9

This means x is everything greater than 9, which satisfies the equation. So in terms of integers, it can be 10, 11, 12, 13...anything above

We want to find the least possible integer value of x, so it is definitely 10

Let the random variable x be equally likely to assume any of the values 1/10, 1/5, or 3/10. determine the mean and variance of x
Keith_Richards [23]
Since the values are equally likely and equally spaced, their mean is the middle one.
  the mean is 1/5

The variance is the average of the square of the deviations from the mean.
  σ² = (1/3)((-1/10)² + 0² + (1/10)²) = 2/300
  the variance is 2/300
