<h3>Answer: irrational number set, real number set</h3>

If the decimal digits do not repeat in some known pattern, then the number is irrational. We cannot write it as a ratio or fraction of two integers. If it did have a pattern, then we can use algebra to find the fractional representation of that number. Based on what is shown, it looks like there is no pattern so that's why the value is irrational. The number is also a real number as this is the case with any number you'll encounter unless you're dealing with complex numbers (but your teacher may not have introduced that topic yet).

What is the approximate area of the circle that fits perfectly inside of the square? Use Pi = 3.14 and round to the nearest tent

Pani-rosa [81]

Answer:

$19.625\text{ cm}^2$

Step-by-step explanation:

GIVEN: A square with base $5\text{ cm}$ , a circle that perfectly fits inside square.

TO FIND: Approximate area of circle.

SOLUTION:

Consider the figure attached.

let the radius of circle be $x\text{ cm}$

radius of circle $=\frac{\text{length of base of square}}{2}$

$x=\frac{5}{2}\text{ cm}$

$x=2.5\text{ cm}$

Area of circle $=\pi(radius)^2$

$=3.14\times(2.5)^2$

$=19.625\text{ cm}^2$

Hence the area of circle that perfectly fits inside the square is $19.625\text{ cm}^2$

A shoe manufacturer collected data regarding men's shoe sizes and found that the distribution of sizes exactly fits the normal c

Lina20 [59]

Answer: 97.72%

Step-by-step explanation:

Given : A shoe manufacturer collected data regarding men's shoe sizes and found that the distribution of sizes exactly fits the normal curve.

Let x be the random variable that represents the shoe sizees.

Also, The population mean = $\mu=11$ ; Standard deviation: $\sigma=1.5$

Formula for z:-

$z=\dfrac{x-\mu}{\sigma}$

Put x= 8, we get

$z=\dfrac{8-11}{1.5}=-2$

Now, the probability that the male shoe sizes are greater than 8 :-

$P(x>8)=P(z>-2)=1-P(z\leq-2)\\\\=1-0.0227501=0.9772499\approx0.9772$

Hence, the percent of male shoe sizes are greater than 8 is 97.72%.
