now adding

[tex]24+16=[/tex] [tex]40 yd^{2}[/tex]

Answer:

x=12 if you divide you'll get 4

Answer:

16

Step-by-step explanation:

If triangle GFE is similar to triangle RST, using the similarity theorem

RS/RT = GF/EF

Using pythagoras theorem;

RT² = 10² - 6²

RT² =100 - 36

RT² = 64

RT = √64

RT = 8

Recall that RS/RT = GF/EF

10/8 = 20/EF

Cross multiply

10EF = 8 * 20

10EF = 160

EF = 160/10

EF = 16

Hence the missing length is 16

Answer:

The percent markup is 25%.

Step-by-step explanation:

Percent markup:

The percent markup is given by the difference in selling price and buying price multiplied by 100% and divided by the buying price.

A department store buys 400 shirts at a cost of $9,600

This means that the buying price is:

$9600/400 = $24

Find the percent markup.

Buying price: $24

Selling price: $30

30 - 24 = 6

6*100%/24 = 25%

The percent markup is 25%.

Step-by-step explanation:

The scenarios which gives a value of 0.4 is depicted by the equations B and C

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

a)

Jesse rode 4 out of 10 miles on his bike.

So , the fraction is A = 4/10 = 0.4

b)

Jesse finished 40 out of 100 math problems.

So , the fraction is A = 40/100 = 0.4

Hence , the equation is A = 0.4

The required surface area of the sphere is given as 113.1 cm².

Given that,
This sphere has a radius of 3 cm. The surface area of the sphere is to be determined.

Surface area is defined as the measure of a region or surface is called as surface area.

Here,
The surface area of the sphere is given as,
The surface area of the sphere = 4πr²
                                                = 4 × 3.14 × 3²
                                                ≈ 113.1

Thus, the required surface area of the sphere is given as 113.1 cm².

Answer:

the mean is 5.8 and the median is 6

Step-by-step explanation:

if you multiply the test scores by their frequencies and then add up all those values, and then divide by the number of test scores, you get 5.8

for the median, you write out all the test scores in order from least to greatest and how many times they appear. then if you go to the middle of that number line, youll find the median

Answer:

c. We have evidence that there is a difference in population median employee satisfaction rating before and after the commission change.

Step-by-step explanation:

Pvalue is less than the alpha-level:

If the pvalue is less than the alpha-level, we have that there is sufficient evidence of the hypothesis for the population mean/median/standard deviation we are testing.

In this question:

Pvalue less than the alpha-level, so there is evidence that there is a difference in the population median. This means that the correct answer is given by option C.

The correct conclusion is: c. We have evidence that there is a difference in population median employee satisfaction rating before and after the commission change.

The given parameters are:

[tex]\mathbf{p = 0.04}[/tex] --- the p-value

[tex]\mathbf{\alpha = 0.05}[/tex] --- the significance value or the alpha level

From the options, we understand that the test parameter is the population median

By comparison, the p-value (0.04) is less than the alpha level (0.05)

When the p-value is less than the alpha-level, then it means that there is enough evidence of the hypothesis for the population parameter that is being tested.

Since the p-value is less than the alpha level, then it means that there is enough evidence to show the difference in the population median.

Hence, option (c) is correct

V = L * W * H

L = 12

W = 6

H = 6

Volume = 12 * 6 * 6

Volume = 432 cubic feet

Answer:

432 cubic feet

Step-by-step explanation:

To find the volume of a retangular prism or a rectangle you use L x W x H so that would be 12 x 6 x 6 which is 432. So the volume is 432 cubic feet

Answer:

x^2+y^2=6^2

Step-by-step explanation:

The equation of a circle is (x-h)^2+(y-k)^2=r^2

where h is the x coordinate of the center, k is the y coordinate of the center, and r is the radius of the circle.

We can see the center is on 0,0, and the radius is 6, so our equation is

(x-0)^2+(y-0)^2=6^2

or

x^2+y^2=6^2

Answer:

[tex] x ^2 + y^2 = 36 [/tex]

Step-by-step explanation:

Center of the circle (h, k) =(0, 0)

Radius of the circle (r) = 6 units

Equation of circle in center radius form is given as:

[tex] (x-h) ^2 + (y-k) ^2 = r^2 [/tex]

[tex] (x-0) ^2 + (y-0) ^2 = (6)^2 [/tex]

[tex] x ^2 + y^2 = 36 [/tex]

3rd option, 1/4

Step-by-step explanation:

decimal form is 0.25

Answer:

a)

P ( R = 20 million ) = 0.00000095367

P ( R = 0 million )  i.e. not winning = 0.99999904633

b)  P ( L ) = ( 1 - p )^l  * p

C)The casino offer the game because  the expected revenue exceeds the winning

Step-by-step explanation:

P( winning ) = P ( getting 20heads in a row ) = 0.5^20 = 0.00000095367

a)  PMF of R

P ( R = 20 million ) = 0.00000095367

P ( R = 0 million )  i.e. not winning = 0.99999904633

b) what is the PMF of L

L = number of loosing clients before winning

P( L = 0 ) = P   i.e. if first contestant wins, if the second contestant win, L=1 repeat same process continuously

P ( L = 2 ) = ( 1 - p)^2 p

Hence the PMF of L  

P ( L ) = ( 1 - p )^l  * p     where p = 0.5^20

C) The casino offer the game because  the expected revenue exceeds the winning

we can prove this using  the relation below

E( L ) =  ( 1 - P ) / 1 - ( 1 - P )

        = 1 / P - 1

where  p = 0.00000095367  ( probability of winning )

Hence E ( L ) = 1048575

hence expected revenue before someone wins

= (1048575 + 1 ) * 20 = $20,971,520
