Let me know the answer plz

Answer:

If x and y are independent events;

[tex]P(x/y)=\frac{P(xny)}{P(y)}=\frac{P(x)*P(y)}{P(y)}=P(x)[/tex]

If x and y are dependent events then;

[tex]P(x/y)=\frac{P(xny)}{P(y)}[/tex]

Step-by-step explanation:

The expression;

P(x|y)  in probability represents the conditional probability of an event x occurring given that an event y has already occurred. An example of such would be; the probability that a student passes the examination given that he attempted all the assignments.

If x and y are independent events, that is the occurrence of y does not in any way influence the occurrence of x, then;

[tex]P(x/y)=\frac{P(xny)}{P(y)}=\frac{P(x)*P(y)}{P(y)}=P(x)[/tex]

If x and y are dependent events then;

[tex]P(x/y)=\frac{P(xny)}{P(y)}[/tex]

[tex]P(xny)[/tex] represents the probability of both x and y occurring together;

Answer:

[tex]G(x)=\frac{1}{2}(x-3)^3+2[/tex]

Step-by-step explanation:

The given function is

[tex]F(x)=x^{3}[/tex]

The transformations to this graph are  in the form;

[tex]G(x)=a(x-b)^3+c[/tex]

where [tex]a=\frac{1}{2}[/tex] is the vertical compression by a factor of [tex]\frac{1}{2}[/tex]

b=3 is a shift to the right by 3 units.

c=2 is an upward shift by 2 units.

Therefore [tex]G(x)=\frac{1}{2}(x-3)^3+2[/tex]

Answer:

The equation is

[tex]G(x)=-\frac{1}{2}(x-3)^3 +2[/tex]

Step-by-step explanation:

If the graph of the function [tex]G(x)=cf(x+h) +b[/tex]  represents the transformations made to the graph of [tex]y= f(x)[/tex]  then, by definition:

If  [tex]0 <|c| <1[/tex] then the graph is compressed vertically by a factor c.

If  [tex]|c| > 1[/tex] then the graph is stretched vertically by a factor c

If [tex]c <0[/tex]  then the graph is reflected on the x axis.

If [tex]b> 0[/tex] the graph moves vertically upwards.

If [tex]b <0[/tex] the graph moves vertically down

If [tex]h <0[/tex] the graph moves horizontally h units to the right

If [tex]h >0[/tex] the graph moves horizontally h units to the left

In this problem we have the function [tex]G(x)[/tex] and our parent function is [tex]f(x) = x^3[/tex]

We know that G(x) is equal to f(x) but reflected on the x-axis ([tex]c <0[/tex]), compressed vertically by a multiple of 1/2 ([tex]0 <|c| <1[/tex] and [tex]c = -\frac{1}{2}[/tex]), displaced 2 units upwards ([tex]b = 2>0[/tex]) and moved to the right 3 units ([tex]h = -3<0[/tex])

Then:

[tex]G(x)=-\frac{1}{2}f(x-3) +2[/tex]

[tex]G(x)=-\frac{1}{2}(x-3)^3 +2[/tex]

Answer:

4n²+2n as a factorial is given as:

[tex]= (2n+1)!/(2n-1)![/tex]

Step-by-step explanation:

We are given an expression which has to be converted into factorial form.

The expression is as follows:

[tex]4n^{2} + 2n\\ = 2n(2n+1)\\ = (2n+1)2n\\[/tex]

Now we know that 2n+1 and 2n differs by '1' and the next smaller term is '2n-1'.

Hence, multiplying and dividing by '(2n-1)!'; we get:

[tex]= ((2n+1)(2n)(2n-1)!)/(2n-1)![/tex]

we know that x(x-1)(x-2)! = x!, so:

[tex]= (2n+1)!/(2n-1)![/tex]

Answer:

Domain is (0,∞)

Step-by-step explanation:

We need to find the domain of the function graphed

Domain are the values of x for which the function is defined.

For domain, we look at the x values of the graph.

We have graph for x values greater than 0. the graph goes close to y axis but does not cross y axis.

For x values greater than 0 there is a value for y.

There is no graph for negative value of x

So , domain is set of all x values greater than 0

Domain is (0,∞)

Answer:

12 cookies and 10 brownies

Step-by-step explanation:

Eder needs 15 cookies and 5 brownies.

Given in the question is Eder needs 6 cookies and 2 brownies for 4 plates.

We have to calculate the cookies and brownies required for 10 plates.

Let's first calculate the cookies by unitary method.

∵ 4 plates required cookies = 6 cookies

∴  1 plate will require cookies = 6/4

∴ 10 plates will require cookies = 6×10/4 = 15

Similarly we will calculate the brownies.

∵ 4 plates required number of brownies = 2

∴ 1 plate will require = 2/4 brownies

∴ 10 plates will require = 2×10/4 = 5 brownies

Therefore 15 cookies and 5 brownies will be required for 10 plates.

Answer:

Josh won the race 5 seconds ahead of Rafael

Step-by-step explanation:

The winner of the race is the individual who completes the race in the shortest time. From the graph, Josh reaches the finish line at the 15 seconds mark while Rafael finishes at the 20 seconds mark.

The difference in the time is thus;

20 - 15 = 5 seconds.

Therefore, Josh won the race 5 seconds ahead of Rafael

Answer:

Gabby received

7 nickels

10 dimes

3 quarters

Step-by-step explanation:

Let

x----> the number of dimes

y----> the number of nickels

z---> the number of quarters

Remember that

1 dime=$0.10

1 nickel=$0.05

1 quarter=$0.25

we know that

0.10x+0.05y+0.25z=2.10 ------> equation A

x=y+3-----> equation B

z=y-4 -----> equation C

substitute equation B and equation C in equation A and solve for y

0.10(y+3)+0.05y+0.25(y-4)=2.10

0.10y+0.30+0.05y+0.25y-1=2.10

0.40y=2.10-0.30+1

0.40y=2.80

y=7 nickels

Find the value of x

x=y+3 -----> x=7+3=10 dimes

Find the value of z

z=y-4 -----> z=7-4=3 quarters

therefore

Answer:

The increase from $3.50 to $8.50 was 243%.

Step-by-step explanation:

The increase from $3.50 to $12.00 was $8.50.

We need to compare this to the original $3.50 by writing the following ratio, evaluating it and converting the result to a percentage:

$8.50

--------- = 2.43

$3.50

Multiply this result by 100%:  (100%)(2.43) = 243%

The increase from $3.50 to $8.50 was 243%.

Answer:

Part a) The distance on a map between Joseph's house and the airport is 2.53 inches

Part b) The distance on a map between the airport and the restaurant is 1.68 inches and the total distance on a map between Joseph's house and the restaurant is 4.21 inches

Step-by-step explanation:

Part a) The actual distance between Joseph's house and the airport is 24 miles. How far apart are Joseph's house and the airport on the map?

we know that

The scale of a map is 1 inch : 9.5 miles

so

using proportion

Find the distance on a map if the  actual distance between Joseph's house and the airport is 24 miles

Let

x-----> the distance on a map

1/9.5=x/24

x=24/9.5=2.53 inches

Part b) Joseph traveled from his house to the airport. He then traveled another 16 miles past the airport to a restaurant. How many inches on the map represent this distance?

we know that

The scale of a map is 1 inch : 9.5 miles

so

using proportion

Find the distance on a map if the  actual distance between airport to the restaurant is 16 miles

Let

x-----> the distance on a map

1/9.5=x/16

x=16/9.5=1.68 inches

The total distance on a map between Joseph's house and the restaurant is equal to

2.53 inches+1.68 inches=4.21 inches

Add the ratios together:

5 +4 = 9

Divide the total amount by t his number:

54 / 9 = 6

Now multiply each side of the ratio by 6:

Sam = 5 x 6 = £30

Bethan = 4 x 6 = £24

Answer:

x = 12

Step-by-step explanation:

Since all 3 angles are congruent then the triangle is equilateral, thus all 3 sides are also congruent.

Equate any 2 of the sides and solve for x

5x - 22 = 3x + 2 ( subtract 3x from both sides )

2x - 22 = 2 ( add 22 to both sides )

2x = 24 ( divide both sides by 2 )

x = 12

Answer:

The value of x is 12

Step-by-step explanation:

* Lets talk about the equilateral triangle

- The three sides of the triangle are equal in length

- The three angles of the triangle are equal in measure

- To find the measure of each one divide the sum of the measures

  of the angles of the triangle by 3

∵ The sum of the measure of the angles in any triangle = 180°

∴ The measure of each angle in the equilateral Δ = 180° ÷ 3 = 60°

* Now lets solve the problem

- From the figure the three angles have the same mark, that means

 the three angles are equal in measure

∵ m∠A = m∠B = m∠C

∴ Δ ABC is equilateral triangle

∴ AB = BC = AC

- WE can use any two sides of them to find the value of x

∵ AB = 4x - 10

∵ BC = 3x + 2

∵ AB = BC

∴ 4x - 10 = 3x + 2 ⇒ add 10 and subtract 3x from both sides

∴ 4x - 3x = 2 + 10 ⇒ add the like terms

∴ x = 12

- To check the answer substitute the value of x in the 3 sides to

 find the length of each side (they must have the same length)

∵ AB = 4x - 10

∴ AB = 4(12) - 10 = 48 - 10 = 38 units

∵ BC = 3x + 2

∴ AB = 3(12) + 2 = 36 + 2 = 38 units

∵ AC = 5x - 22

∴ AB = 5(12) - 22 = 60 - 22 = 38 units

- All the sides are equal, then the value of x is right

* The value of x is 12

Step-by-step explanation:

Well, we can divide 399 and 75 so it would be 5.32. Round that and it would be about 5 items per page

The required average number of items per page is 5.32.

A rate with a second term of one is referred to as a unit rate. To put it another way, a unit rate compares two quantities, with the second number being expressed as 1. Unit rates, such as price per item, speed per hour, or cost per pound, are frequently used to describe a rate per unit of measurement.

Here,
To find the average number of items per page, we need to divide the total number of items by the number of pages:

The average number of items per page = Total number of items / Number of pages

Substitute the given values, and we get:

The average number of items per page = 399 / 75

Simplifying the expression, we get:

The average number of items per page = 5.32 (rounded to two decimal places)

Therefore, the average number of items per page is 5.32.
