Answer:

The union of two event

Step-by-step explanation:

Addition law of probability  define that probability of two event  is total sum of probability of any event subtract the probability of both events

There are two rules  in addition law:

Addition law 1 -  when both event are mutually exclusive, then probability of either event is the sum of each event probability.

P( A or B) = P(A) +P(B)

Addition law 2 -  when both events are non mutually exclusive then there in addition to the individual probability there is some overlap .

P( A or B) = P(A) +P(B) - P(A and B)

It should be noted that addition law is potentially helpful when we are interested in computing the probability of The union of two event.

According to this question, we are to discuss about Addition law of probability.

As a result of this we can see that Addition law of probability  explain about probability for either of two mutually exclusive events which is occurring and also  the probability of two non-mutually exclusive events that is occurring.

Answer: To produce treatment groups with similar characteristics

Step-by-step explanation:

The purpose of this experiment is to determine that the treatments groups with similar characteristics are produced. Every groups is taking different amount of the supplement so this study ensures that by randomly assigning the supplements, we can check the cholesterol level in the blood. In this way, similar characteristics in groups are imparted so we can then make treatment groups of same characteristics.

The purpose of random assignment in experiments is to avoid bias, increase the research results' accuracy, help in producing treatment groups with similar characteristics, and control confounding variables. In this case, it ensures that all participants have an equal chance of receiving any level of omega-3 fatty acid or placebo.

The purpose of random assignment in this experiment is multifold. Firstly, it ensures all participants, regardless of their cholesterol levels, have an equal chance of being selected. This prevents bias in the sample selection. Secondly, it increases the accuracy of the research results by preventing skewness in the data. The random assignment ensures that every participant has an equal chance of receiving any level of the omega-3 fatty acid supplement or the placebo. This helps produce treatment groups with similar characteristics, which in turn allows for fair comparisons to be made. Finally, it aids in controlling confounding variables. These are factors other than the independent variable (in this case, omega-3 fatty acid supplements) that may affect the dependent variable (cholesterol level), and random assignment helps to equalize these among the groups.

Step-by-step explanation:

let 4th fourth vertex be D (x,y)

A(2 1/3,7 1/2),B(12, 7 1/2),C(12,1)

or A(7/3,15/2),B(12,15/2),C(12,1)

Mid-point of diagonal AC is  P((7/3+12)/2,(15/2+1))

Mid -point of diagonal BD is P((12+x)/2,(15/2+y)/2)

(Because mid -point of diagonal is same.)

(12+x)/2=(7/3+12)/2

12+x=7/3+12

x=7/3

(15/2+1)/2=(15/2+y)/2

15/2+1=15/2+y

y=1

so fourth vertex is (7/3,1)

To find the coordinates of the fourth vertex of the rectangle, we use the information provided about the positions of the third vertex and the Car X figure. The coordinates of the fourth vertex are (13 2/3, 7 1/2) and (12, 2).

To find the coordinates of the fourth vertex of the rectangle, we can use the fact given that the third vertex is one and two-thirds perpendicular hash marks to the right of the center top hash mark. Since the center top hash mark is at (12, 7 1/2), the third vertex is at (12 + 1 2/3, 7 1/2), which simplifies to (13 2/3, 7 1/2).

Now, we need to find the position of the fourth vertex. According to the given information, the fourth vertex is in the same position as the Car X figure, which means it is one perpendicular hash mark above the center right hash mark. Since the center right hash mark is at (12, 1), the fourth vertex is at (12, 1 + 1), which simplifies to (12, 2).

Therefore, the coordinates of the fourth vertex are (13 2/3, 7 1/2) and (12, 2).

Answer:

80 buses will be required for 1120 soldiers.

Step-by-step explanation:

Given:

Number of seats on One side = 12 seats.

Now Given:

five seats are reserved for equipment.

So we can say that;

Number of seats used by soldiers = [tex]12-5=7\ seats[/tex]

Number of soldiers on Each seat =2

So we will now find number of soldiers on each bus.

number of soldiers on each bus is equal to Number of seats used by soldiers multiplied by Number of soldiers on Each seat.

framing in equation form we get;

number of soldiers on each bus = [tex]7\times2 = 14\ soldiers[/tex]

Now we know that;

For 14 soldiers = 1 bus

So 1120 soldiers = Number of buses required for 1120 soldiers.

By Using Unitary method we get;

Number of buses required for 1120 soldiers = [tex]\frac{1120}{14} =80[/tex]

Hence 80 buses will be required for 1120 soldiers.

Answer:

The total amount of commission on these vehicles is 1686.

Step-by-step explanation:

Given:

Miles earns a 6% commission on each vehicles he sells.

Today he sold a truck for 18500 and a car for 9600.

Now, to get the total amount of his commision on these vehicles.

Percent of commission Miles earns on each vehicles he sells = 6%.

He sold a truck for = 18500.

He sold a car for = 9600.

So, the total amount of vehicles:

[tex]18500+9600=28100.[/tex]

Now, to get the total amount of commission on vehicles:

[tex]6\%\ of\ 28100[/tex]

[tex]=\frac{6}{100} \times 28100[/tex]

The factored form is  [tex](8x-32)=8(x-4)[/tex]

Step-by-step explanation:

Given : A youth club receives a discount on each pizza purchased for a party. The original price of each pizza is x dollars. The club leader purchases 8 pizzas for a total of (8x-32) dollars.

To find : Factor the expression ?

Solution :

The original price of each pizza is x dollars.

The club leader purchases 8 pizzas for a total of [tex](8x-32)[/tex] dollars.

To factor the expression we have to take common term out.

So, [tex]8x=8\times x[/tex]

[tex]32=8\times 4[/tex]

8 is common take out,

[tex](8x-32)=8(x-4)[/tex]

Factors are 8 and (x-4).

Therefore, the factored form is  [tex](8x-32)=8(x-4)[/tex]

To factor the expression (8x - 32), we take out the common factor of 8, resulting in the factored form of 8(x - 4), indicating a $4 discount per pizza.

The question is asking to factor the expression, which represents the total cost for purchasing 8 pizzas after receiving a discount from the original price x dollars per pizza. The expression given is (8x - 32) dollars.

To factor this expression, we look for a common factor in both terms which is 8.

Factoring out the 8, we get 8(x - 4). This means the club receives a discount of $4 per pizza since (8x - 32) factors into 8 times (x - 4).

Answer:

Therefore the value of x are = -1 and -5 for which f(x)=g(x).

Step-by-step explanation:

Given,

f(x)=x²+6x+6    and    g(x)=1

f(x)=g(x)

⇒x²+6x+6=1

⇒x²+6x+6-1=0

⇒x²+6x+5=0

⇒x²+5x+x+5=0

⇒x(x+5)+1(x+5)=0

⇒(x+5)(x+1)=0

⇒x+5=0     or       x+1=0

⇒x=-5                     x=-1

Therefore the value of x are = -1 and -5.

To find the values of x for which f(x) equals g(x), we set the equations x² + 6x + 6 equal to 1 and solve. The quadratic equation factors to yield x = -1 and x = -5 as solutions.

To find the values of x for which f(x) equals g(x), we need to set the functions equal to each other and solve for x:

Given:
f(x) = x² + 6x + 6
g(x) = 1

We need to solve for x when:

x² + 6x + 6 = 1

Subtract 1 from both sides to set the equation to zero:

x² + 6x + 5 = 0

Next, we factor the quadratic equation:

(x + 1)(x + 5) = 0

Set each factor to zero and solve for x:

x + 1 = 0
x = -1

x + 5 = 0
x = -5

Thus, the values of x for which f(x) = g(x) are x = -1 and x = -5.

Let x represent the total number of red and blue beads

Angie has some red and blue beads. 40% of her beads were red. This means that the total number of red beads is

40/100 × x = 0.4x

The number of blue beads would be

x - 0.4x = 0.6x

When she lost 50 blue beads, the number of blue beads was reduced by 1/3 its original number of beads. This means that

0.6x - 50 = 0.6x - 0.6x/3

0.6x - 50 = 0.6x - 0.2x = 0.4x

0.6x - 0.4x = 50

0.2x = 50

x = 50/0.2 = 250

The number of blue beads that Angie had initially is

0.6 × 250 = 150

The number of blue beads that Angie has left is

150 - 50 = 100 beads

The number of beads that Angie has in the end is

250 - 50 = 200 beads

Explanation:

To solve any equation that is linear in the variable of interest, you first look at what is done to the variable, using the Order of Operations as your guide.

Here, the variable is ...

You find the value of the variable by reversing these steps, starting from the last one on the list and working up the list.

To "undo" the addition of "b", we add its opposite (-b) to the equation. The rules of equality tell you that anything you do to one side of the equation must also be done to the other side, so we add -b to both sides:

  ax +b -b = c -b

  ax = c -b . . . . . . . . simplify

To "undo" the multiplication by "a", we multiply by its reciprocal. That is, we multiply by 1/a, or, equivalently, divide by "a". Again, we must do this to both sides of the equation:

  (1/a)ax = (1/a)(c -b)

  x = (c -b)/a . . . . . . . simplify

__

In short, we subtract the added constant (b) and divide by the multiplier (a).

Answer: her regular hourly rate is $12.5

Step-by-step explanation:

Let x represent the regular payment that Sonya receives per hour for the first 40 hours of work. This means that her total pay for the first 40 hours of work is

40 × x = $40x

Sonya is paid time and a half for hours worked in excess of 40 hours. This means that her hourly pay for working more than 40 hours would be x + 0.5x = $1.5x

She worked for 52 hours. This means that the extra hours that she worked is

52 - 40 = 12 hours

Total pay for 12 extra hours is

12 × 1.5x = 18x

If she had gross weekly wages of $725, then

40x + 18x = 725

58x = 725

x = 725/58 = $12.5

To find Sonya's regular hourly rate, we need to calculate her overtime pay and then subtract it from her total weekly wages.

To find Sonya's regular hourly rate, we need to calculate her overtime pay and then subtract it from her total weekly wages. Sonya earned $725 for 52 hours worked. Since she is paid time and a half for hours worked more than 40, she worked 12 overtime hours (52 - 40 = 12).

Her overtime pay is calculated by multiplying her regular hourly rate by 1.5, so her overtime pay is 1.5 * regular hourly rate * 12 hours. Subtracting her overtime pay from her total wages gives us her regular wages, so we have the equation: $725 - (1.5 * regular hourly rate * 12) = regular wages. Solving for  regular hourly rate will give us the answer.

Answer:

Step-by-step explanation:

Let us record the station number 1, 2 or 3 for each family member A, B or C.

I am attaching a table containing total outcomes. Outcomes are presented along rows while the assigned station to each member is written along columns. For ease of understanding, 1 3 2 in the table should be interpreted as family member A being assigned to station 1, member B to station 3 and member C to station number 2, respectively.

From table it is clear that the total outcomes possible are 27.

We know that, probability can be defined as,

[tex]PROBABITILY = \frac{NUMBER\;OF\;DESIRED\;OUTCOMES}{TOTAL\;NUMBER\;OF\;OUTCOMES}[/tex]

a) All Members Assigned to the Same Station.

Cases for all members being assigned to same station are as follows:

[1 1 1], [2 2 2], [3 3 3] (outcome number 1, 14 and 27 in the table).

Therefore,

[tex]PROBABILITY\;(Case\;a) = \frac{3}{27}\\\\PROBABILITY\;(Case\;a) = 0.111[/tex]

b) At Most Two Members Assigned to the Same Station.

It means that maximum of 2 members can have the same station. Cases for this situation are as follows:

[1 1 2], [1 1 3], [1 2 1], [1 2 2], [1 3 1], [1 3 3], [2 1 1], [2 1 2], [2 2 1], [2 2 3], [2 3 2],

[2 3 3], [3 1 1], [3 1 3], [3 2 2], [3 2 3], [3 3 1], [3 3 2]

(outcome number 2, 3, 4, 5, 7, 9, 10, 11, 13, 15, 17, 18, 19, 21, 23, 24, 25 and 26 in the table).

Therefore,

[tex]PROBABILITY\;(Case\;b) = \frac{18}{27}\\\\PROBABILITY\;(Case\;b) = 0.666[/tex]

c) All Members Assigned to a Different Station.

For this scenario, we have the following results:

[1 2 3], [1 3 2], [2 1 3], [2 3 1], [3 1 2], [3 2 1] (outcome number 6, 8, 12, 16, 20 and 22 in the table).

Therefore,

[tex]PROBABILITY\;(Case\;c) = \frac{6}{27}\\\\PROBABILITY\;(Case\;c) = 0.222[/tex]
