Answer:

75π / 2

Step-by-step explanation:

a = (∅ / 2π) * πr²

a = (3π/4 / 2π) * π(100)

a = (3/8) * 100π

a = 300/8 * π

a = 75/2 * π

a = 75π / 2

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

$\text {Hello! Let's Solve this Equation!}$

$\text {\underline {The First Step is to Subtract 3p}}$

$\text {24p-66-3p=3p+43-3p}$

$\text {Your New Problem Is: 21p-66=43}$

$\text {\underline {The Next Step Is to Add 66}}$

$\text {21p-66+66=43+66}$

$\text {Your New Problem Is: 21p=109}$

$\text {\underline {The Final Step is to Divide 21}}$

$\text {21p/21=109/21}$

$\text {Your Answer Would Be:}$

$\fbox {p=109/21}$

$\text {Best of Luck!}$
