Answer:
A
Step-by-step explanation:
Here as we can see that minimum drink a person can drink is 0 and is
(3.5-0)/2 =1.75 std deviation away from mean
which reflects that distribution;s right tail is more extended
therefore option A is correct: Distribution is right skewed
Answer:
4 is in the hundredths 1 is in thousandths 9 is in the 10 thousandths
The new area will be 320 in²
<em><u>Explanation</u></em>
Lin has a drawing with an area of 20 in² and she increases all sides by a scale factor of 4.
<u>The general rule</u> we need to use here.......
"<em>If the lengths of the sides in a shape are all increased by a scale factor of , then the area will be increased by a scale factor of "</em>
Here the sides are increased by a scale factor of 4. So, the area will be increased by a scale factor of
Thus, the new area will be:
Answer:
Step-by-step explanation:
They want you to see how radius is important. Just remember that one radian is one radius, that should help you see why radius is important.
They ask for the unit circle , that is a circle of one unit for the radius, which makes it super easy to calculate things for it, they ask what is the area, which is that famous formula, π , then they ask what's its circumference. which is that other famous formula 2πr
so to go all the way around a circle of one unit radius, it's 2π exactly or about 6.28..... units, call it meters, or feet or inches, it doesn't mater here.
the size of the circle doesn't matter here either, b/c we are using the radius , that relaationship doesn't change , all circles, what ever size , have this same relationship between the radius and radians. :P this is handy.
