What is the fraction, decimal,Ratio for 71.4%

Harrizon [31]

Answer:

Fraction: $\frac{357}{500}$

Decimal: 0.714

Ratio is 357:500

Step-by-step explanation:

<u />

<u>The fraction of 71.4%</u>

$\frac{71.4}{100}$

Multiplying the numerator and denominator by 10 gives;

$\frac{714}{1000}$

Dividing the numerator and denominator by 2 gives

$\frac{357}{500}$ (no other common divisor)

<u>The decimal value of 71.4%</u>

<u />

We divide 71.4 by 100 to get 0.714

<u>The ratio of 71.4%</u>

<u />

The simplified fraction of 71.4% is $\frac{357}{500}$

So the simplified ratio is 357:500

Find the radius of a sphere with a surface area of 804 cm^2.

Elanso [62]

Surface area of sphere equals its four radii squared multiplied by the number π.
We have then:
A = 4 * π * R ^ 2
Substituting:
804 = 4 * π * R ^ 2
Clearing the value of R we have:
R = root (804 / (4 * π))
R = 7.99876785 cm
Nearest whole number:
R = 8 cm
Answer:
The radius of a sphere is:
B. 8cm

an employee is selected from a staff of 10 to super- vise a certain project by selecting a tag at random from a box containing 1

USPshnik [31]

Probability that the number drawn is less than 4 is given by 0.3

<h3>What is probability?</h3>

The likelihood of an event happening is gauged by probability.

The probability might be between 0 and 1, where 0 denotes an impossibility and 1 denotes a certainty.

The overall chance of every event in a sample space is 1.

Let random variable X represent the number of the drawn tag.

Since the simple space consists of 10 equally likely events

S = {1,2,3,4,5,6,7,8,9,10}

The formula for probability distribution is given by:

f(x) = { (1/10) for x = 1,2....10, else 0 elsewhere

since, each number can equally likely occur, therefore

P(x) = 1/10 = 0.1

Probability that the number drawn is less than 4 is given by:

P(x<4) = P(1) + P(2) + P(3)

= 0.1 + 0.1 + 0.1

= 0.3

What are the domain and range of the function f(x)=-3(x-5)2 +4?

Xelga [282]

Answers:

Domain is $(-\infty, \infty)$

Range is $(-\infty, 4]$

============================================

Explanation:

We can replace x with any real number we want. We don't have any restrictions to worry about since there are no division by zero issues for instance. Also, there isn't any issues of things like taking the square root of a negative number.

Therefore, the domain is the set of all real numbers which translates to the interval notation of $(-\infty, \infty)$

This interval notation can be thought of as $-\infty < x < \infty$

----------------------------

The range on the other hand isn't the set of all real numbers. It might help to graph this parabola (see below). You should see that the highest point occurs at the vertex (5, 4). This then tells us that the largest y can get is y = 4.

In other words, y = 4 or y can be smaller than this.

In symbols, we would say the range is $y \le 4$ and that translates to the interval notation of $(-\infty, 4]$

The curved parenthesis always goes with either infinity. The square bracket says "include the endpoint 4 as part of the interval".
