Answer:

a. The data is skewed left

Step-by-step explanation:

Looking at the graph, the bars are noticeably much taller on the right side when compared to the left.

The mean is likely less than the median, if calculated.

The skewed side of the graph is opposite to what it looks like.

3x(x + 6) = -10

emmasim [6.3K]

Answer:

Step-by-step explanation:

Expand it: $3x^2 + 18x = -10$

Add 10 to both sides: $3x^2 + 18x + 10 = 0$

Divide both sides by 3: $x^2 + 6x + \frac{10}{3} = 0$

Find a, b for $(x + a)^2 + b = x^2 + 2x + a^2 + b \overset{!}{=} x^2 + 6x + \frac{10}{3}$

It’s $a = \frac{6}{2} = 3 \land b = \frac{10}{3} - a^2 = 3 + \frac{1}{3} - 9 = -6 + \frac{1}{3}$

So, inserting it leads to: $(x+3)^2 -6 + \frac{1}{3} = 0$

Subtract b from both sides: $(x+3)^2 = 6-\frac{1}{3}$

Apply square root to both sides and consider the two solutions: $x + 3 = \pm\sqrt{6-\frac{1}{3}}$

Subtract 3 from both sides and you get $x = -3 \pm \sqrt{6 - \frac{1}{3}}$
