<h3>Answer: B. Graph is nearly symmetrical</h3>

Explanation:

Given information:

  • A number line going from 2 to 11.  
  • 0 dots are above 2.  
  • 0 dots are above 3.  
  • 1 dot is above 4.  
  • 2 dots are above 5.  
  • 4 dots are above 6.  
  • 4 dots are above 7.  
  • 3 dots are above 8.  
  • 2 dots are above 9.  
  • 2 dots are above 10.  
  • 0 dots are above 11.

From that we can see the data set is {4,5,5,6,6,6,6,7,7,7,7,8,8,8,9,9,10,10} which produces the dot plot you see in the image attachment below.

It's a bit tricky to see, but the graph is nearly symmetrical. If we were to remove the blue points in the dot plot I provided, then we'll get a perfectly symmetrical distribution. Symmetrical means one half is a mirror copy of the the other half. The center line of a symmetrical distribution is both the mean and median.

If sin θ = 1 over 3 and tan θ &lt; 0, what is the value of cos θ?
alexira [117]

Answer:

2√2 / 3 (first answer choice)

Step-by-step explanation:

If tan Ф < 0, then Ф must be in either Quadrant II or Quadrant IV.

If sin Ф = +1/3, then Ф (for this problem) is in Quadrant II.

Remembering that sin Ф = opp / hyp = 1 / 3, we use the Pythagorean Theorem to find the adj side:

adj² + 1² = 3²,  or

adj² + 1 = 9, or    adj² = 8.  Since Ф is in Quadrant II, adj is negative.

The value of cos Ф = adj / hyp = √8 / 3 = 2√2 / 3

She paid 26.35 for something that would usually be 31 dollars. what percent discount did she get
Alex17521 [72]

<u>Answer:</u>

She paid 26.35 for something that would usually be 31 dollars. The percentage discount she got is 15%

<u>Solution:</u>

A lady paid $26.35 for something that is usually $31, so she got a discount for the product.

Now, we have been asked to find out how much percentage discount she got.

To do that we first have to check how many dollars she got off the product.

To do so we have to subtract the discounted price from the initial price.

Therefore we get:

31 - 26.35 = 4.65

To find the percentage discount we need to do the following

\begin{array}{l}{=\frac{4.65}{31} \times 100} \\\\ {=0.15 \times 100 = 15}\end{array}

Therefore she got a discount of 15%

The directex of Y=1/8x^2 is?

\bf \textit{parabola vertex form with focus point distance}\\\\&#10;\begin{array}{llll}&#10;(y-{{ k}})^2=4{{ p}}(x-{{ h}}) \\\\&#10;\boxed{(x-{{ h}})^2=4{{ p}}(y-{{ k}})} \\&#10;\end{array}&#10;\qquad &#10;\begin{array}{llll}&#10;vertex\ ({{ h}},{{ k}})\\\\&#10;{{ p}}=\textit{distance from vertex to }\\&#10;\qquad \textit{ focus or directrix}&#10;\end{array}\\\\&#10;-------------------------------\\\\&#10;y=\cfrac{1}{8}x^2\implies (y-0)=\cfrac{1}{8}(x-0)^2\implies 8(y-0)=(x-0)^2&#10;\\\\\\&#10;4(2)(y-0)=(x-0)^2\impliedby \textit{that means, p = 2}

so... if you notice, the vertex is at h,k and that'd be the origin, 0,0

so...since the directrix is "p" units from the vertex, so it'd be 2 units from 0,0

now, the parabola has an equation with a positive leading term's coefficient, namely the 1/8 is positive, thus, the parabola is opening upwards, and the directrix is "outside" the parabola, so is below the vertex

that puts the directrix 2 units below 0,0

to rent a popcorn machine, it costs 35 dollars plus 6.95 dollars for each hour. Write and evaluate an expression to find the tot
nekit [7.7K]

Answer:

<em>equation=</em>35+6.95h=c

5 hours=  $69.75

6 hours= 76.7

7 hours= 83.65

8 hours= 90.6

Step-by-step explanation:

the equation is found by adding 35 (the cost of the machine) and 6.95 times how many hours. To find the hours after 5 just add 6.95 every time.
