Answer:

  [tex]\dfrac{\sqrt[4]{3x^2}}{2y}[/tex]

Step-by-step explanation:

Fourth powers (and multiples of 4th powers) can be factored out from under the radical. Everything else remains under the radical.

  [tex]\sqrt[4]{\dfrac{24x^6y}{128x^4y^5}}=\left(\dfrac{3\cdot8}{16\cdot8}x^{6-4}y^{1-5}\right)^{1/4}=(3\cdot2^{-4}x^{2}y^{-4})^{1/4}\\\\=\boxed{\dfrac{\sqrt[4]{3x^2}}{2y}}[/tex]

_____

The applicable rules of exponents are ...

  a^(b/c) = c-th root of (a^b)

  (a^b)(a^c) = a^(b+c)

  (a^b)^c = a^(bc)

  a^-b = 1/a^b

Answer:

Step-by-step explanation:

the answer is (D) [tex]\sqrt[4]{3x^2}[/tex] / 2y

Answer:

0.5563

Step-by-step explanation:

Given that :

Probability of winning (p) = 0.15

Number of months = number of trials (n) = 5

1 - p = 1 - 0.15 = 0.85

Probability of winning atleast one price ;

P(x = x) = nCx * p^x * (1 - p)^(n-x)

P(x≥1) = p(1) + p(2) + p(3) + p(4) + p(5)

Using the binomial probability calculator to save computation time :

P(x≥1) = 0.556294

P(x≥1) = 0.5563

Probabilities are used to determine the chances of events.

The probability that you win at least one prize is 0.5563

The given parameters are:

[tex]p = 0.15[/tex] --- the probability of winning

The probability of losing (q) is then calculated using the following complement rule

[tex]q= 1 - p[/tex]

[tex]q= 1 - 0.15[/tex]

[tex]q= 0.85[/tex]

The probability that you win at least one prize is the complement of not winning at all.

So, we have:

[tex]P(At\ least\ 1) = 1 - P(None)[/tex]

This gives

[tex]P(At\ least\ 1) = 1 - 0.85^5[/tex]

[tex]P(At\ least\ 1) = 1 - 0.4437[/tex]

Evaluate like terms

[tex]P(At\ least\ 1) = 0.5563[/tex]

Hence, the probability of winning at least one prize is 0.5563

Answer:

Step-by-step explanation:

According to Triangle P R Q, if  angles R P Q and P Q R are congruent, this means that two of the sides of the triangle a re also congruent (Isosceles triangle).

We can say then that length of side PR is equal to that of RQ i.e PR = RQ

Given

PR = 5n

RQ = 32+n

Required

Length of PR

Since the two sides are equal i.e PR = RQ

5n = 32+n

5n - n = 32

4n = 32

n = 32/8

n = 4

Get PR;

Since PR = 5n

PR = 5(4)

PR = 20

Hence the length of PR is 20.

Answer:

40

Step-by-step explanation:

Answer:

Well, we know that the interior angles of any triangle add up to 180. We also know that a pair of supplementary angles adds up to 180. Furthermore we know that the figure in an iscoceles triangle. We know this since the 2 lines of the triangle are marked with a bisecting arc indidcating that they are equal in length. Therefore the 2 base angles are equal by the rules of an isosceles triangle. Let M and N represent the 2 base angles:

by using the rule that the interior angles add up to 180 we see that 56 +m +n=180

M and n are the same values since this is an isosceles triangle.

56 +m +n=180

m+n=124

Since m and n are the same values we just divide 124 by2

m, n=62

Therefore by using the rules of supplementary angles if the base angles equal 62 then the m<1 and 62 should add up to  180 since suplementary angles add up to 180. 180-62=118

m<1=118

Answer:

The distance between points 8 and -5 is 13

Step-by-step explanation:

We need to find distance between points 8 and -5

The formula used to find the distance is: [tex]Distance=|b-a|[/tex]

Absolute value is used to get only positive values. i.e |-1|=1 if required.

We are given: b=8 and a=-5

Putting values and finding distance

[tex]Distance=|b-a|\\Distance=|8-(-5)|\\Distance=|8+5|\\Dstance=|13|\\Distance=13[/tex]

So, the distance between points 8 and -5 is 13

Answer:

Step-by-step explanation:

A ratio says how much of one thing there is compared to another thing.

ratio 3:1

There are 3 blue squares to 1 yellow square

Ratios can be shown in different ways:

Use the ":" to separate the values: 3 : 1

Or we can use the word "to": 3 to 1

Or write it like a fraction: 31

A ratio can be scaled up:

ratio 3:1 is also 6:2

Here the ratio is also 3 blue squares to 1 yellow square,

even though there are more squares.

Credits to math is fun

ratios compare two quantities

basically ratios are usually in the form x : y (x to y), where the quantity of x is compared to the quantity of y. there can be different values for x and y in this case. they can either both be part of a whole, or one can be part of a whole while the other is the whole.

Answer:

You have to translate these sentences into expressions.  I am not going to solve all of these because if I explain one/two problems to you, you'll get the hang of it.  Seven more than three times a number: 7+3x; Five times a number decreased by six: 5x-6

Step-by-step explanation:

Why?  We don't know what number that is, so we can put any variable like (x, y, z, a, b, etc.). Three times a number is simply that number times 3.  In this case we would input: 3*x, or 3x.  7 more than that number is 3x+7.  Five times a number decreased by six: 5x-6 .  Remember: it is simply 5*x which simplifies to 5x.  Decreased is take away, so take away 6, and get 5x-6

Key words: Quotient: the result after dividing two/or more numbers; Product: the result after multiplying two/ or more numbers; Decreased: take away (Example: x decreased by 7=x-7)

I hope you understand!! It is very simple after you start to get the hang of it!!

Answer:

  b.  slope: 2; y-intercept: -20

Step-by-step explanation:

The y-intercept is the first point in the table, where x=0. That eliminates choices A and D.

The slope is the difference in y divided by the difference in x. Using the first and second points in the table, this is ...

  (-10 -(-20))/(5 -0) = 10/5 = 2

The slope is 2; the y-intercept is -20.
