Answer:

y=-\dfrac{1}{2}(x+4)^2-1

Step-by-step explanation:

Vertex form:  y=a(x-h)^2+k  

where:

  • (h, k) is the vertex
  • a is some constant

Given:

  • vertex = (-4, -1)
  • point on parabola = (-2, -3)

Substitute given values into the formula to find a:

\implies -3=a((-2)-(-4))^2+(-1)

\implies -3=a(2)^2-1

\implies -3=4a-1

\implies -2=4a

\implies a=-\dfrac{2}{4}=-\dfrac{1}{2}

Therefore, the equation of the parabola is:

y=-\dfrac{1}{2}(x+4)^2-1

Answer: C.

Not symmetric; not bell-shaped

Step-by-step explanation:

Data is mainly right skewed. In simpler terms the data has more if a "tail" on the right side while most of the data is on the left. If you were to trace a line over each last dot (the one's at the top) all the way to the last point. You would see that it does not make a "bell-shape" but more of the shape of an arrow pointing left. If it were symmetrical it would have more of a balanced amount of data points on it's opposite side which would make the shape either look like a triangle or a bell shape. Hope that helps.

What is the measure of xyz
kakasveta [241]

Answer:

The correct answer is option B.  65

Step-by-step explanation:

<u>To find the measure of <VYX</u>

Central angle of arc VW = 44°

Therefore m<VXY = 44/2 = 22°

And central angle of arc XZ = 86° therefore <XVY = 86/2 = 43

<u>To find the mesure of <XYZ</u>

m<XYZ = m<VXY + m<XVY

  = 22 + 43

 = 65°

Therefore the correct answer is option B. 65°
