The options that apply to the given table of data are; Options C, D & E

<h3>How to Interpret Frequency Tables?</h3>

Option A: Conditional relative frequency compares a frequency count to the marginal total that represents the condition of interest. Thus, the given statement is not true because it compares the frequency count of the 18 people to a fraction.

Option B: The principle of Independence states that two events A and B are statistically independent if and only if their joint probability can be factorized into their marginal probabilities. This shows principle of independence and so the statement is wrong.

Option C: Marginal Relative Frequency is the ratio between the frequency of a row total or column total to the total frequency of the data. Thus, the given statement is correct.

Option D: This statement is true because joint relative frequencies are the values in each category divided by the total number of value.

Option E; This statement is correct because the table shows principle of Independence

Movie Ticket Sales : 6x + 9y = 1,500 Which graph shows this relationship?

sukhopar [10]

Ok so we have movie ticket sales and we have 6x+9y=1,500. So for types of graphs, we have linear, exponential, quadratic, and those are the basic types of graphs. Now looking at the equation, we can quickly see that the answer is linear because, looking at the constant, 1500 and the other numbers, we can see the graph will be increasing linear. Hope this helped, feel free to ask questions if you have any!

When you divide two fractions, you're actually multiplying one of them by the reciprocal of the other. First, find the reciprocal of the second fraction by flipping it upside down. Then, multiply it by the first fraction. (Numerator x numerator and denominator x denominator)

$\frac{-7}{12}$ ÷ $\frac{2}{3}$ Replace the second fraction with it's reciprocal
$\frac{-7}{12}$ x $\frac{3}{2}$ Multiply (-7 x 3 and 12 x 2)
$\frac{-21}{24}$ Both 21 and 24 are divisible by three, so divide them by 3
$\frac{-7}{8}$

A parabola can be drawn given a focus of

Volgvan

Answer:

$y=-\frac{1}{4}(x-2)^{2}+9$

Step-by-step explanation:

Any point on a given parabola is equidistant from focus and directrix.

Given:

Focus of the parabola is at $(2,8)$ .

Directrix of the parabola is $y=10$ .

Let $(x,y)$ be any point on the parabola. Then, from the definition of a parabola,

Distance of $(x,y)$ from focus = Distance of $(x,y)$ from directrix.

Therefore,

$\sqrt{(x-2)^{2}+(y-8)^{2}}=|y-10|$

Squaring both sides, we get

$(x-2)^{2}+(y-8)^{2}=(y-10)^{2}\\(x-2)^{2}=(y-10)^{2}-(y-8)^{2}\\(x-2)^{2}=(y-10+y-8)(y-10-(y-8))...............[\because a^{2}-b^{2}=(a+b)(a-b)]\\(x-2)^{2}=(2y-18)(y-10-y+8)\\(x-2)^{2}=2(y-9)(-2)\\(x-2)^{2}=-4(y-9)\\y-9=-\frac{1}{4}(x-2)^{2}\\y=-\frac{1}{4}(x-2)^{2}+9$

Hence, the equation of the parabola is $y=-\frac{1}{4}(x-2)^{2}+9$ .
