The mean is the average.
To solve for the average we add all the numbers up and divide by how many numbers there are.
21, 23, 25, 25, 26, 28, 28, 28, 31, 33.
268 total, now divide by how many numbers there are.
268/10
Your mean is 26.8

Answer:

$14 ( 5)^{\frac{1}{4}} p^{\frac{1}{4}} q^{\frac{1}{2}} r^{2}$

Step-by-step explanation:

The expression to simplify in this problem is

$7\sqrt[4]{80pq^2r^8}$

Which can be rewritten as

$7(80pq^2r^8)^{\frac{1}{4}}$

Or also as

$7\cdot 80^{\frac{1}{4}} \cdot p^{\frac{1}{4}} \cdot (q^2)^{\frac{1}{4}} \cdot (r^8)^{\frac{1}{4}}$

Now we can apply the following rule for the calculation of the power of a power:

$(a^m)^n = a^{m\cdot n}$

So we get:

$7\cdot 80^{\frac{1}{4}} \cdot p^{\frac{1}{4}} \cdot q^{\frac{1}{2}} \cdot r^{2}$

Which can therefore be rewritten as

$7\cdot (2^4\cdot 5)^{\frac{1}{4}} \cdot p^{\frac{1}{4}} \cdot q^{\frac{1}{2}} \cdot r^{2}$

And so, we get

$7\cdot 2 \cdot ( 5)^{\frac{1}{4}} \cdot p^{\frac{1}{4}} \cdot q^{\frac{1}{2}} \cdot r^{2}$

which can be finally rewritten as

$14 ( 5)^{\frac{1}{4}} p^{\frac{1}{4}} q^{\frac{1}{2}} r^{2}$

What is the scientific notation for 140000

vampirchik [111]

You move the decimal point forward until it reaches the one so it looks like this:

1.4 x 10⁵

the exponent, 5, just tells you how many spaces the decimal point moved.

Answer:

46.19 feets

Step-by-step explanation:

Using Pythagoras rule :

Sin θ = opposite / hypotenus

Let length of string = s

Sin 60 = 40 / s

s * 0.8660254 = 40

s = 40 / 0.8660254

s = 46.188021 feets

s = 46.19 feets
