Answer:

There is no mode in the set

B. Because the mean is less than the median comma this distribution's shape is left dash skewed.

Step-by-step explanation:

Data set = {25, 18, -9, 14,32}

We find sum = 80 hence mean = 80/5 = 16

No mode since nothing is more repeated

Median is the middle entry after arranging in ascending order = 18

a) x bar=16

b) median = 18

c) mode is nil

Here median - mean >1

so negatively skewed

There is no mode in the set

B. Because the mean is less than the median comma this distribution's shape is left dash skewed.

What is the solution set to the inequality 5(x - 2)(x + 4) > 0?

Butoxors [25]

Answer:

You selected the correct answer: {x | x < -4 or x > 2}

Step-by-step explanation:

5(x - 2)(x + 4) > 0

Use FOIL method to expand (x - 2)(x + 4):

$5(x^{2} + 2x - 8)$ > 0

Distribute 5 into $(x^{2} + 2x - 8)$

$5x^{2} + 10x - 40$ > 0

Divide all terms by 5 from both sides of the inequality:

$\frac{5x^{2}}{5} + \frac{10x}{5} - \frac{40}{5} > \frac{0}{5}$

$x^{2} + 2x - 8 > 0$

Factor the trinomial:

(x + 4) ( x - 2) > 0

x < -4 or x > -2

Therefore, the solution set to the inequality is {x | x < -4 or x > 2}

Interval notation: (-∞, -4) ∪ (2, ∞)
