In the sample space, the annotation for the event where both E and G but not F occurs is given as:( E ∩ G ) ∩ Fc (Option B).

An event is a specified set of results of a random experiment in probability theory. Because the sample space is the collection of all potential outcomes of a random experiment, another definition of an event is any subset of a sample space.

Colloquially, the sample space for a given set of events is the collection of all potential values for the events. Technically, a sigma-algebra is formed by the set of probable occurrences for a given random variate, and sample space is defined as the biggest set in the sigma algebra.

a) ( Ec ∪ G ) ∩ Fc

b) ( E ∩ G ) ∩ Fc

c) ( E ∪ G ) ∪ Fc

d) ( Ec ∪ Gc ) ∩ F

e) ( E ∩ G ) ∩ F

f) None of the above.

The annotation for the event in the sample space when E and G both occur but F does not is given as:( E ∩ G ) ∩ Fc which is the correct answer would be an option (B).

In probability theory, an event is a predetermined group of outcomes from a random experiment. Another definition of an event is any subset of a sample space, which is the collection of all possible results of a random experiment.

We are allowed to use here for the necessary notation, though one way to indicate this is the complement of E U F U G. This would be the area in the sample space S that lies outside E, F, and G in a Venn diagram.

Thus, the annotation for the event in the sample space when E and G both occur but F does not is given as:( E ∩ G ) ∩ Fc

For the given condition of dimes is 8 times of nickel and there are 18 dimes and nickels altogether, then total money is equal to $1.

As given in the question,

Let x be the number of dimes

Then number of nickels are 8x.

As per given condition,

Total number of dimes and nickels = 18

⇒ x + 8x = 18

⇒ 9x = 18

⇒ x= 2

Number of dimes =2

Number of nickels = 8(2)

                             = 16

Conversion:

1 dime = 0.10$

1 nickel = 0.05$

Total amount of money in dollars

= 2 ×(0.10) + 16× (0.05)

= 0.20 + 0.80

= 1.00

Therefore, for the given condition of dimes is 8 times of nickel and there are 18 dimes and nickels altogether, then total money is equal to $1.

Circumference of a circle ⭕ = [tex] 2 \pi r [/tex]

Where,

r = d/2

d means diameter

r = 4/2 = 2

So, substitute to equation C = 2πr

If the tank contains 12 gallons and then the car consumes 10, we can know how much gasoline is left by substracting 12 with 10:

12 - 10 = 2

Then, 2 gallons of gasoline is left in the tank

Since there is still gasoline because 12 is higher than 10, then we represent this amount with a positive value.

Answer:

y = ( 6 / 5 )x - 5;

Step-by-step explanation:

y = - ( 1 / m )x + c;

Convert dual intercept to standard form.

5x + 6y = 18;

Subtract 5x from both sides.

6y = - 5x + 18;

Divide both sides by 6.

y = ( - 5x + 18 ) / 6;

y = ( - 5x / 6 ) + ( 18 / 6 );

y = ( - 5 / 6 )x  + 3;

Get the perpendicular line.

y = ( 6 / 5 )x + c;

Substitute the point.

7 = ( 6 / 5 )( 10 ) + c;

7 = 12 + c;

Subtract 12 from both sides.

- 5 = c;

c = - 5;

y = ( 6 / 5 )x - 5;

We can describe 15x-10 as an expression.

We would describe 6x-2<35 as an inequality.

In mathematics, inequalities characterize the connection between two non-equal numbers. Inequality means being unequal. If two values are not equal, we use the "not equal symbol". However, various inequalities are employed to compare the numbers, whether they are less than or higher than.

An inequality in mathematics is a relationship that makes a non-equal comparison between two integers or other mathematical expressions. It is most commonly used to compare two numbers on the number line based on their size. In the illustration above, there's a less than sign. This means that it's an inequality.

8. -3 < x

Step-by-step explanation:

The salesperson needs to make weekly sales of $9,500 to earn the same amount with each option.

The amount he earns by option A can be calculated as follows;

As he works 40 hours per week and the hourly wage is $19; therefore the amount he will earn can be determined by multiplication as follows;

Option A earning: 40 × 19 = $760

Thus, the salesperson earns $760 through option A.

Consider x to be the amount of weekly sales;

As the commission rate is 8% of sales therefore 8% of x should be equal to $760 for the salesman to earn the same amount with both options.

(8/100)x = 760

0.08x = 760

x = 760 / 0.08

x = 9,500

Hence the salesman needs to make weekly sales of $9,500 to earn the same amount with both options.

Although there is a mistake in your question, you might be referring to this question;

It is to be noted that by the proof given below, the attached shape ABCD is a kite.

A kite is a quadrilateral having reflection symmetry across a diagonal in Euclidean geometry. A kite has two equivalent angles and two pairs of adjacent equal-length sides as a result of its symmetry.

The proof is as follows:

AB = AD [Given]

∠ADC = 115°   [Angles on a Straight line]

That is 180 - 65 = 115°

∠BCD = 20°    [Vertical Angles are equal]

We want to find the opposite of the number 4.5

The opposite of a number is the number that is the same distance from 0 on the number line but on the other side.

So, if the number is on the right hand side, its opposite is on the left hand side.

In simpler terms, the opposite of a number is the negative of a number.

Answer:

$30 dollars for 75 copies

Step-by-step explanation:

What we know:

$4 for every 10 copies.

How to figure out:

Divide 4/10 = .4    .4 is the cost per copy.

We do this because if it is 4 dollars per 10 copies, then we have to figure out the cost per copy. So we have to do how many dollars goes into each copy.

Now we know the cost of one copy we can multiply the amount of copies we need by the price of one.

75 x 0.4 = 30     30 is the price of 75 copies.
