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>

55, 55, 60, 60, 70, 80, 80, 80, 90, 120

(55*2+ 60*2+ 70+ 80*3 + 90+ 120)/10 = 75

(20*2+15*2+5+5*3+15+45)/10 = 15

<h3>Neighborhood 2</h3>

100, 110, 110, 110, 120, 120, 120, 140, 150, 160

(100 + 110*3+ 120*3+ 140 + 150+ 160)/10 = 124

(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).

The graphs below have the same shape. What is the equation of the red graph?

arsen [322]

Answer:

Step-by-step explanation:

The red graph is vertically shifted from the blue graph. Let's understand horizontal and vertical shifts.

If we have a graph of $f(x)=x^2$ , then

f(x) + a is a units shifted vertically up
f(x) - a is a units shifted vertically down
f(x-b) is b units shifted horizontally right
f(x+b) is b units shifted horizontally left

Since the red one is vertically shifted 3 units up (compared to blue graph), the equation would be:

$g(x)=f(x)+3\\g(x)=x^2 + 3$

Correct answer is D

To compute a student's Grade Point Average (GPA) for a term, the student's grades for each course are weighted by the number of

Liula [17]

Okay, here we have this:

Considering the provided information and grades, we are going to calculate the requested GPA, so we obtain the following:

Then we will substitute in the following formula:

$GPA=\frac{Grades\ast Credits}{Total\text{ credits}}$

Then:

$\begin{gathered} GPA=\frac{3.8\cdot5+1.9\cdot2+3.0\cdot5+2.8\cdot4}{16} \\ GPA=\frac{19+3.8+15+11.2}{16} \\ GPA=\frac{49}{16} \\ GPA=3.06 \end{gathered}$

Finally we obtain that the student's GPA for that term is approximately 3.06.

Ana went to the grocery store and bought 3 apple pies from the bakery for $27.30. What is the unit price for each pie?

Andrews [41]

27.30/3 = x/1

then divide both sides by 3
27.30 divided by 3 is 9.1

therefore, the answer is $9.10
