Volume of cereal box=19.5*30*6.5=3802.5cc. The volume of cereal is 80% of this=0.8*3802.5=3042cc.

Volume of the cereal bowl is 2/3(pi)r^3 (half the volume of a sphere 4/3(pi)r^3) where r=radius=12/2=6cm. The volume is therefore 2/3(pi)*216=144(pi)cc.

The number of full cereal bowls is 3042/144(pi)=21.125/(pi)=6.72. So 6 cereal bowls can be filled from the cereal in one cereal box.

The stem & leaf show demonstrates that 0.55 for both the data is indeed a reasonable value.

The probable outlier is the data value 0.76.

The variability of the techniques is relatively large.

It show isn't symmetrical and seems to be optimistic.

7w - 3(4w + 8) = 11 <br>Solve​
Eduardwww [97]

Answer:

7w - 3(4w + 8) = 11

Distribute.

-5w-24=11 Combine like terms on the left side.

-5w=11%2B24 Add 24 to both sides.

-5w=35 Combine like terms on the right side.

w=%2835%29%2F%28-5%29 Divide both sides by -5 to isolate w.

w=-7 Reduce.
