11.9+7m=10m (subtract 7m from both sides)
-7m -7m
11.9/3=3/3m (divide both sides by 3 to find m)
3.96666= m

Scrat [10]

Question

Marcus asked 10 people at a juggling festival what age they were when they started to juggle. Which interval contains the median age?

Answer:

See Explanation

Step-by-step explanation:

Given

$n = 10$

Required

The median interval

The question is incomplete, as the required data is not given.

To solve this question, I will use the following assumed dataset.

$Age:17\ 17\ 18\ 20\ 21\ 22\ 22\ 24\ 28\ 28$

First, calculate the median position.

$Median = \frac{n+1}{2}\ th$

$Median = \frac{10+1}{2}\ th$

$Median = 5.5\ th$

This implies that the median is the mean of the 5th and 6th data

So, we have the interval to be.

$Median = [5th, 6th]$

$Median=[21,22]$

<em>Generally, the median of 10 data set is located at interval 5 to 6</em>

The monthly demand for a company’s sports caps varies directly as the amount spent on advertising and inversely as the square of

Amanda [17]

Answer: $\$16.432$

Step-by-step explanation:

Let be "y" the monthly demand for the company’s sports caps, "x" the amount in dollar spent on advertising and "z"the price ind dollars per cap.

The model for this situation is:

$y=\frac{kx}{z^2}$

Where "k" is the constant of proportionality.

Since $y=300$ when $z=15$ and $x=2,500$ , we can substitute values into $y=\frac{kx}{z^2}$ and solve for "k" to finds its value:

$300=\frac{k(2,500)}{15^2}\\\\\frac{(300)(15^2)}{2,500}=k\\\\k=27$

Then, in order to calculate what price yields a demand of 300 caps when advertising is increased to $3,000, we must substitute the following values into $y=\frac{kx}{z^2}$ :

$x=3,000\\\\y=300\\\\k=27$

Then:

$300=\frac{(27)(3,000)}{z^2}$

Solving for "z" we get:

$z^2=\frac{(27)(3,000)}{300}\\\\z=\sqrt{\frac{(27)(3,000)}{300}}\\\\z=16.432$

In a party decorations total r balloons were used. There were b blue balloons, twice as many green balloons, and the rest of bal

Montano1993 [528]

Answer:

No. of yellow balloons = r - b - $\frac{b}{2}$

Step-by-step explanation:

Total number of balloons = r

No of blue balloons = b

Blue balloons are twice the no of green balloons. so

No. of green balloons = $\frac{b}{2}$

No of yellow balloons = ( Total number of balloons ) - ( No of blue balloons ) - ( No. of green balloons )

⇒ No. of yellow balloons = r - b - $\frac{b}{2}$
