The equivalent expression is the one in the last option:

[tex]\sqrt[10]{y}[/tex]

Here we want to find an expression equivalent to:

[tex](\frac{1}{\sqrt{y} } )^{-1/5}[/tex]

Remember the two rules for exponents that we need to use here:

[tex]x^{-n} = (1/x)^n[/tex]

[tex]x^{1/n} = \sqrt[n]{x}[/tex]

Using the first rule, we can rewrite our expression as:

[tex](\frac{1}{\sqrt{y} } )^{-1/5} = \sqrt{y}^{1/5}[/tex]

Now we can rewrite the root of a root to get:

[tex](\frac{1}{\sqrt{y} } )^{-1/5} = \sqrt{y}^{1/5} = \sqrt[5]{\sqrt{y} } = \sqrt[10]{y}[/tex]

Where in the last step we just multiplied the exponents for the roots, we can see that the correct option is the last one.

Answer: about 87.96459430051421

Step-by-step explanation: 28 x 3.14 = the answer

This question involves using the binomial distribution.

Let X be the number of male high school lacrosse players who will play at the college level out of the 20 selected players . We can model X as a binomial random variable with parameters n=20 and p=0.128, where p is the probability of success (i.e., a player going on to play at the college level).

The probability of exactly 4 players playing at the college level is given by the formula:

P(X=4) = (20 choose 4) * (0.128)^4 * (1-0.128)^(20-4)

Using a calculator, we can evaluate this expression to find:

P(X=4) = 0.155

Therefore, the probability that exactly four of the 20 male high school lacrosse players selected at random will end up playing at the college level is 0.155, or between C and 1 (inclusive).

Note that we rounded to three decimal places as requested .

Step-by-step explanation:

Answer:

(a) width = 71 ft; (b) length = 77 ft

Step-by-step explanation:

(a) The formula for area of a rectangle is

A = lw, where

Because we're already given the area and length, we can find the width by plugging everything into the formula and solve for width, w:

6319 = 89w

71 ft = w

(b) The formula for perimeter of a rectangle is

P = 2l + 2w, where

Since we're given the perimeter and width this time, we can plug everything into the formula and solve for l:

272 = 2l + 2(59)

272 = 2l + 118

154 = 2l

77 ft = l

We can check our answers for (a) and (b) by plugging in the length and width for (a) into the area formula and seeing whether we get 6319 and plugging in the length and width for (b) into the perimeter formula and seeing whether we get 272

Checking answers for (a):

6319 = 89 * 71

6319 = 272

Checking answers for (b):

272 = 2(77) + 2(59)

272 = 154 + 118

272 = 272

To write the ratio of 2/3 to 8 as a fraction in simplest form, we need to divide the numerator and denominator by their greatest common factor (GCF).The GCF of 2 and 8 is 2.So, we divide both the numerator and denominator by 2:2/3 ÷ 8/1 = (2/3) ÷ (8/1) = 2/3 x 1/8 = (2 x 1) / (3 x 8) = 2/24Now, we can simplify the fraction by dividing the numerator and denominator by their greatest common factor again.The GCF of 2 and 24 is 2.So, we divide both the numerator and denominator by 2:2/24 ÷ 2/2 = (2/24) ÷ (2/2) = 2/24 x 1/2 = (2 x 1) / (24 x 2) = 1/12Therefore, the ratio of 2/3 to 8 as a fraction in simplest form is 1/12.

Answer:

How to find Ratio?

Ratios compare two numbers, usually by dividing them. If you are comparing one data point (A) to another data point (B), your formula would be A/B. This means you are dividing information A by information B. For example, if A is five and B is 10, your ratio will be 5/10

In order to find the ratio of a certain number to another number or the relation of each other, we also need to know the concept of fraction and percentage.

1/12 or 1 to 12

The ratio is 2/3*8=23⋅8=2/24=1/12

So it is 1 to 12

The number of jerseys that the senior class at Legion Academy can purchase for $430, using quadratic equation, is 190.

Quadratic equation is an algebraic equation of the second degree in x, represented in the form of ax²+bx+c=0.

In the quadratic equation, a, b, and c are known values but a ≠ 0 and x is unknown.

x = [-b ± √b² - 4ac]/2a

when ax^2 + bx + c = 0

C = 0 .1x² + 2.4x + 25, where C is the amount, it costs to buy x jerseys.

Simplifying the equation, we get:

x = 0.2 − 2.4 ± 40.4​

The two possible values of x are:

1) x = 0.2 − 2.4 + 40.4​ = 190

or

2) x = 0.2 − 2.4 − 40.4 ​= −214

The value of x cannot be negative, therefore, the class bought 190 jerseys for $430.

Based on the given data, the probabilities of the spinner landing on each color are approximately:

Red: 0.3469

Blue: 0.2449

Green: 0.0816

Yellow: 0.2449

Purple: 0.0816

To calculate the probability of the spinner landing on a specific color, we need to divide the frequency of that color by the total number of spins.

Given the spinner results:

Color Frequency

Red 17

Blue 12

Green 4

Yellow 12

Purple 4

To find the probability of landing on a specific color, we divide the frequency of that color by the total number of spins:

Probability (Red) = Frequency (Red) / Total Spins

= 17 / (17 + 12 + 4 + 12 + 4)

= 17 / 49

= 0.3469 (rounded to four decimal places)

Probability (Blue) = Frequency (Blue) / Total Spins

= 12 / 49

= 0.2449 (rounded to four decimal places)

Probability (Green) = Frequency (Green) / Total Spins

= 4 / 49

= 0.0816 (rounded to four decimal places)

Probability (Yellow) = Frequency (Yellow) / Total Spins

= 12 / 49

= 0.2449 (rounded to four decimal places)

Probability (Purple) = Frequency (Purple) / Total Spins

= 4 / 49

= 0.0816 (rounded to four decimal places)

The size of the land that Muya's son and daughter received is [tex]1\frac{11}{12}[/tex] hectares.

We can see that, Muya started with a [tex]6\frac{2}{3}[/tex] hectares piece of land, which we can write as an improper fraction i.e.:

[tex]6\frac{2}{3}[/tex] = (6 × 3 + 2) / 3 = [tex]\frac{20}{3}[/tex] hectares

The Muya donated [tex]\frac{7}{8}[/tex] hectares to a school and [tex]1 \frac{1}{2}[/tex] hectares to a children's home. The total amount of land he donated is:

[tex]= \frac{7}{8}+ \frac{11}{2} \\\\= \frac{7}{8} + \frac{3}{2} \\\\= \frac{14}{8} + \frac{12}{8} \\\\= \frac{26}{8} \\\\= \frac{13}{4} hectares[/tex]

The size of the land left is:

[tex]\frac{20}{3} - \frac{13}{4} = (\frac{80}{12}) - (\frac{39}{12}) = \frac{41}{12} hectares[/tex]

Muya's son and daughter share this remaining land equally, so each of them gets:

[tex](\frac{41}{12}) / 2 = \frac{20.5}{12} = 1 \frac{11}{12} hectares[/tex]

Therefore, the size of the land that Muya's son and daughter received is 1 11/12 hectares.

The equation that passes through the point (4, -3) and has a slope of 4 is option A: 5x + 4y = 8.

To determine which equation passes through the point (4, -3) and has a slope of 4, we can substitute the values of x and y into each equation and check if the resulting equation is true.

Let's substitute x = 4 and y = -3 into each equation:

A. 5x + 4y = 8

Substituting x = 4 and y = -3:

5(4) + 4(-3) = 20 - 12 = 8

The equation is true for points (4, -3).

B. 5x - 4y = 8

Substituting x = 4 and y = -3:

5(4) - 4(-3) = 20 + 12 = 32

The equation is not true for points (4, -3).

C. 4x + 5y = 8

Substituting x = 4 and y = -3:

4(4) + 5(-3) = 16 - 15 = 1

The equation is not true for points (4, -3).

D. 4x - 5y = 8

Substituting x = 4 and y = -3:

The reason is that the median is less affected by extreme values or outliers which can greatly affect the mean. In this case, the mean annual salary is $62,000 while the median is only $35,000.

This large difference suggests that there are some very high earners at the company that are pulling up the mean. The median indicates that half of the employees earn less than $35,000 and half earn more which gives a more accurate picture of the typical salary at the company.

Answer:

18 square units

Step-by-step explanation:

The parallelogram has been plotted in the attached figure

The area of a parallelogram is b x h

where b is one side and h is the vertical distance between the two bases

In the figure, we see that base = AB is parallel to the y-axis

This means the y-coordinates of A and B are the same and the distance is obtained by taking the absolute difference between the x-coordinates of A and B

b = |x1 - 2| = |6 - 0| = 6

The height h is a perpendicular line from point D(1, 3) to the base which touches the base at point E

Since this line is horizontal to the x-axis in the figure, the y coordinates of the endpoints of the line are the same i.e y1 =3 and y2 = 3

Therefore h = absolute difference between the x coordinates
= |1-4| = 3

Given b = 6, h = 3

area = 6x 3 = 18 square units
