C ≥ 0.35
That is an inequality to represent the cost of an MP3 song.
Answer:
0 1 2 2 3 3 3 4 4 5
Mode is 3
Median is 3
Mean is 2.7 I think
Step-by-step explanation:
Mode is most common
Median middle number when put in order
Mean add all up and divide by how many there is
Answer:
Julie weighs 35 lbs, Ted weighs 70 lbs, Mike weighs 105 lbs.
Step-by-step explanation:
Let the weight of Julie be
Given:
Ted weighs twice as much as Julie
Weight of Ted =
Mike weighs three times as much as Julie.
Weight of Mike =
Together, Ted, Mike, and Julie weigh 210 lbs.
Solving above we get;
Hence Julie weight is 35 lbs.
Weight of Ted =
Hence Ted weight is 70 lbs.
Weight of Mike =
Hence Mike weight is 105 lbs.
Answer:
C)49π
Step-by-step explanation:
Given:
As in given figure there are two right triangle,
Let the bigger right triangle be ABC
and the smaller right angle be ADE
Finding length of hypotenuse of ΔABC
h
h=AC=13
Now as the two right triangles are similar as both have one angle common i.e. A, and one right angle i.e. 90 degree.
As ΔABC is similar to ΔADE
BC/AC=DE/AE
5/13=r/(12-r)
r= (12-r)0.384
r= 4.615-0.384r
r+0.384r =4.615
1.384r=4.615
r=4.615/1.384
r=3.33
Now volume of the inscribed sphere
volume=4/3πr^3
putting value of r=3.33 in above
volume=4/3π(3.33^3)
=49.23π
= 49π !
le'ts take a peek at the ages, 9, 6 and 5, so their ratio will be in the order of 9:6:5, what we firstly do is divide the total by that many pieces, namely 100 ÷ (9+6+5) and then distribute accordingly.
