Answer:
1/2
Step-by-step explanation:
Based on the information observed from the attached box and whisker plot, the Fraction of dunk tanks which requires atleast 500 gallons of water. This fractional value will be the property of plot in the position marked as 500 on the plot. The point which refers to 500 gallons on the plot is the ticked point in between the box. This point represents the median value in a box and whisker plot.
The median value represents the 50th percentile value which relates to half of the distribution. This means that fraction of dunk which requires atleast 500 gallons is : (50/100) = 1/2
<span>So we want to know how many students out of 144 practice martial arts every day if we know that 7/12 practice every day. So lets multiply the numerator and the denumerator with 12. We will get (12*7)/(12*12)=84/144. And we got our answer: 84 out of 144 students practice every day.</span>
The answer would be -7/8. Hope this helps!
Area of the base is πr² where r is the radius. The volume of a cone is ⅓ πr²h where h is the height.
So the volume is ⅓ π×9×10=30 π=94.25 cu in approximately.
System of inequalities:
Graph is shown below.
<h2>
Explanation:</h2>
Let:
x: Number of hour Charlene makes babysitting
y: number of hour Charlene makes gardening
We can represents each statement using inequalities as follows:
<h3>First statement:</h3>
<em>Charlene makes $10 per hour babysitting and $5 per hour gardening. She wants to make at least $80 a week,</em>
- The amount of money she makes babysitting is:
- The amount of money she makes gardening is:
- She wants to make at least $80 a week
<em>At least </em>in this context means that the minimum amount of money she can makes is $80. In other words, if a is at least b we write:
Then, in this context:
<h3>Second statement:</h3>
<em>She can work no more than 12 hours a week. </em>
<em>No more </em>in this context means that the maximum numbers of hours she can work in a week is 12. In other words, if a no more than b we write:
So:
So, our system of inequalities would be:
By using graphing tool, we get the graph below. The solution is that where both the region of the first and second inequality overlap. Keep in mind that the symbols ≥ ≤ tells us that $80 and 12 hours respectively are included in our solution..
