Okay so the circumference of a circle is pi×the diameter or 2×radius× pi. In this case we are given the radius so
C=2×20×3.14
C=40×3.14
C=125.60
The circumference is 125.60cm

Given:

mean, u = 0

standard deviation σ = 1

Let's determine the following:

(a) Probability of an outcome that is more than -1.26.

Here, we are to find: P(x > -1.26).

Apply the formula:

z=\frac{x^{\prime}-u}{\sigma}

Thus, we have:

\begin{gathered} P(x>-1.26)=\frac{-1.26-0}{1} \\  \\ P(x>-1.26)=\frac{-1.26}{1}=-1.26 \end{gathered}

Using the standard normal table, we have:

NORMSDIST(-1.26) = 0.1038

Therefore, the probability of an outcome that is more than -1.26 is 0.1038

(b) Probability of an outcome that

What is the distributive property of 4+10
IgorC [24]

Answer:

  2(2 +5)

Step-by-step explanation:

We presume you want to rewrite the expression making use of the distributive property. For that, it is helpful to find a factor common to the two terms. The GCD of 4 and 10 is 2, so we can factor that out:

  4 + 10 = 2(2 +5)

_____

Of course, you can use any factor you like. It doesn't need to be an integer.

  = (1/3)(12 +30)

  = 0.4(10 +25)

  = 4(1 +2.5)

Given: x - 6.3333 ≤ 1.5 .
Inessa05 [86]

Answer:

x or (-\infty, 47/6]

Step-by-step explanation:

Note that 6.3333 = 6 1/3 = 19/3 = 38/6.

Also, note that 1.5 = 1 1/2 = 3/2 = 9/6.

So, the inequality is really equal to x-38/6.

We can then add 38/6 to both sides to get x.

So, the solution is x, or in interval notation, (-\infty, 47/6]
