Answer:
1.6 hours
Step-by-step explanation:
Putting this into an equation, it would be (12 ÷ -3) + - (14 x 4)
-4 + -56 = -60
Answer:
As per dot plots we see the distribution of prices is close but majority of prices are concentrated in different zones. So MAD would be more similar by the look.
<u>Let's verify</u>
<h3>Neighborhood 1</h3>
<u>Data</u>
- 55, 55, 60, 60, 70, 80, 80, 80, 90, 120
<u>Mean</u>
- (55*2+ 60*2+ 70+ 80*3 + 90+ 120)/10 = 75
<u>MAD</u>
- (20*2+15*2+5+5*3+15+45)/10 = 15
<h3>Neighborhood 2</h3>
<u>Data</u>
- 100, 110, 110, 110, 120, 120, 120, 140, 150, 160
<u>Mean</u>
- (100 + 110*3+ 120*3+ 140 + 150+ 160)/10 = 124
<u>MAD</u>
- (24+14*3+4*3+16*3+16+26+36)/10 = 20.4
As we see the means are too different (75 vs 124) than MADs (15 vs 20.4).

ANSWER
EXPLANATION
The equation of a parabola in factored form is
where 'a' is the leading coefficient and 'm' and 'n' are the zeros.
From the question, the zeros of the parabola are 6 and −5.
This implies that,
We plug in these zeros to get:
If (-1, 3) is a point on the graph of this parabola,then it must satisfy its equation.
We substitute x=-1 and y=3 to obtain:
The first choice is correct.
