Answer:

  QT = 16

  VQ = 24

Step-by-step explanation:

The centroid divides each median into parts that have the ratio 1:2. The short length is the one from the centroid to the side (VT); the long length is the one from the centroid to the vertex (QT).

VT : QT = 1 : 2 = 8 : 16

VQ = VT +QT = 8 + 16 = 24

__

QT = 16

VQ = 24

Answer:

The best measure of center for a set of data is the median value.

To find the median list the values from

Smallest to largest:

0, 0, 1, 1, 2,2, 2, 14

Since there is an even number of values, find the middle two numbers, add them together and divide by 2:

1+2 = 3

3/2 = 1.5

The answer is median 1.5

Henry cut 1.5 m of the wire.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Henry cut 12.5% of the 12 m wire, which is:

= 1.5 m

Therefore,

Henry cut 1.5 m of the wire.

Answer:   [tex]\sqrt{3}+\sqrt{5}[/tex]

On a keyboard, we could type this as sqrt(3) + sqrt(5)

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

Explanation:

The given expression is considered a nested radical because one radical, the [tex]\sqrt{15}[/tex], is buried inside another radical.

Let's assume that nested radical is of the form [tex]\sqrt{a}+\sqrt{b}[/tex] where a & b are positive real numbers.

Set the given expression equal to [tex]\sqrt{a}+\sqrt{b}[/tex] and square both sides to see what happens. We'll do a bit of algebra to simplify and rearrange things a bit as well. See the steps below.

[tex]\sqrt{8+2\sqrt{15}} = \sqrt{a}+\sqrt{b}\\\\\left(\sqrt{8+2\sqrt{15}}\right)^2 = \left(\sqrt{a}+\sqrt{b}\right)^2\\\\8+2\sqrt{15} = \left(\sqrt{a}\right)^2 + 2\sqrt{a}\sqrt{b} + \left(\sqrt{b}\right)^2\\\\8+2\sqrt{15} = a + 2\sqrt{ab} + b\\\\8+2\sqrt{15} = (a+b) + 2\sqrt{ab}\\\\[/tex]

If we equate terms, we get this system of equations

[tex]\begin{cases}8 = a+b\\2\sqrt{15} = 2\sqrt{ab}\\\end{cases}[/tex]

Solve the first equation for 'a' to get a = 8-b

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

Let's plug a = 8-b into the second equation and solve for 'b'

[tex]2\sqrt{15} = 2\sqrt{ab}\\\\\sqrt{15} = \sqrt{ab}\\\\15 = ab\\\\15 = (8-b)b \ \ \text{ .... replace a with 8-b}\\\\15 = 8b-b^2\\\\b^2-8b+15 = 0\\\\(b-3)(b-5) = 0\\\\b-3 = 0 \ \text{ or } \ b-5 = 0\\\\b = 3 \ \text{ or } \ b = 5\\\\[/tex]

If b = 3, then a = 8-b = 8-3 = 5

If b = 5, then a = 8-b = 8-5 = 3

We have this symmetry going on with 'a' and b. If one value is 3, then the other is 5, and vice versa. The order doesn't matter.

That means the equation

[tex]\sqrt{8+2\sqrt{15}} = \sqrt{a}+\sqrt{b}\\\\[/tex]

updates to

[tex]\sqrt{8+2\sqrt{15}} = \sqrt{3}+\sqrt{5}\\\\[/tex]

The order doesn't matter on the right side since we can add two numbers in any order.

---------

You can use your calculator to confirm the answer.

Note that

[tex]\sqrt{8+2\sqrt{15}} \approx 3.968118785[/tex]

and

[tex]\sqrt{3}+\sqrt{5} \approx 3.968118785[/tex]

both result in the same decimal approximation to help show the two sides are equal.

Answer:

0.18203 = 18.203% probability that exactly four complaints will be received during the next eight hours.

Step-by-step explanation:

We have the mean during a time-period, which means that the Poisson distribution is used to solve this question.

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

In which

x is the number of sucesses

e = 2.71828 is the Euler number

[tex]\mu[/tex] is the mean in the given interval.

A service center receives an average of 0.6 customer complaints per hour.

This means that [tex]\mu = 0.6h[/tex], in which h is the number of hours.

Determine the probability that exactly four complaints will be received during the next eight hours.

8 hours means that [tex]h = 8, \mu = 0.6(8) = 4.8[/tex].

The probability is P(X = 4).

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

[tex]P(X = 4) = \frac{e^{-4.8}*4.8^{4}}{(4)!} = 0.18203[/tex]

0.18203 = 18.203% probability that exactly four complaints will be received during the next eight hours.
