Since they have the same denominator (4) which is the number on the bottom of the fraction, you can just add the numerators (3 and 4), which are on the top of the fraction, together:
3/4 + 4/4 = 7/4
Answer:
Step-by-step explanation:
The formula of volume of cone is
V=\frac{1}{3}\pi r^{2} h
where, r is the radius
we have given diameter = 12 =2r
r=6 ft
h is the height h=6 ft
\pi =3.14
Substitute the value in the formula,
V=\frac{1}{3}\pi r^{2} h
V=\frac{1}{3}\times (3.14)\times 6^{2}\times 6
V=\frac{1}{3}\times 3.14\times 36\times 6
V=226.08 ft^3
Therefore, The volume of cone is 226.08 cubic ft.

Answer:
<h2>
The mean decreases, and the median remains the same.</h2>
Step-by-step explanation:
Remember that a box plot is made by the quartiles of the distribution, the maximum value and the minimum value. So, from a box plot we can deduct the range, the median and the interquartile range.
In this case, the median remains the same at $9.5 per hour. The median is indicated by the middle line of the box, and you can observe that it doesn't change.
Now, the range of the data set decreases from 7 to 3.
On the other hand, the mean must decrease, because data greater than $11 doesn't exist in the box plot number 2, and the mean is a central measure sensible to those changes.
Therefore, the right answer is <em>The mean decreases, and the median remains the same.</em>
