Answer: c. [tex]P(I \text{ or }\overline{H})[/tex]

Step-by-step explanation:

Notation to show "not an event E" : [tex]\overline{E}[/tex]

Given:  I = the event that a player in an infielder.

H = the event that a player is a great hitter.

= the event that a player is not a great hitter.

The correct symbol for the probability that a player is an infielder or is not a great hitter : [tex]P(I \text{ or }\overline{H})[/tex]

hence, the correct option is  c. [tex]P(I \text{ or }\overline{H})[/tex]

Answer:

The sum does not exist, but if you are in a senior math class, it could be - infinity.

Step-by-step explanation:

If the sum does not have an endpoint (and it looks like it does not), then the sum really does not exist.

Consider this question.

Does the sum stop at 0 as in

50 + 40 + 32  + 24 + 16  + 8 + 0

But why not - 8 or - 16 or ...

So it is not that the sum does not exit. It is that we do not know where that stop is. Depending on your grade level, you could answer - infinity, but I doubt that is the expected answer.

The price of sunglasses is greater original price and 0.45 is tax amount.

A tax is a mandatory fee or financial charge that a government imposes on a person or a business in order to raise money for public projects like building the greatest infrastructure and services.

Taxes are required financial contributions imposed by a government body, whether local, regional, or federal, on people or businesses. Tax revenues are used to fund a variety of government initiatives, such as Social Security and Medicare as well as public infrastructure and services like roads and schools.

Given:

Original price of sunglasses = $10.

Price according to cashier= $10.45

So, the price of sunglasses is greater original price.

and, the difference both price

= 10.45 - 10

= 0.45 is tax amount.

Answer:

The equations are x=a and y=b.

The graph of x=a is a line parallel to y-axis and y=b is a line parallel to x-axis.

∴ the angle between them is 90o, i.e. they intersect.

So, the equations are consistent.

Now solving simultaneously, the solution is (a,b).

So, the point of intersection is (a,b).

Hence, option D is correct.

Answer:

A. 20

Step-by-step explanation:

The two functions are equal at the point where the line of both function intercept. At this point, equilibrium is achieved.

The number chairs demanded and the number of chairs supplied are equal at this point.

Both lines intersect at x = 20. This means 20 (in hundreds) chairs must be sold for equilibrium to be achieved.

Answer:

5.1

Step-by-step explanation:

=======================================================

Explanation:

First we need to find the slope of this given line.

The two points on here are (0,-3) and (3,0)

Apply the slope formula

m = (y2-y1)/(x2 - x1)

m = (0-(-3))/(3-0)

m = (0+3)/(3-0)

m = 3/3

m = 1

The slope of the given line is 1. The negative reciprocal of this is -1, which is the perpendicular slope.

Side Note: Any two perpendicular lines always have their slope multiply to -1, as long as neither line is vertical.

Answer:

perpendicular lines have an inverse slope and place a negative sign on it too so our give line is as below  

Step-by-step explanation:

P1 = (0, -3)  in the form ( x1, y1)

P2 = (3 , 0 )  in the form (x2, y2)

m= slope  

m = y2-y1 / x2 - x1

m = 0-(-3) / 3 - 0

m = 3 / 3

m = 1

since our slope of the given line is 1 then a perpendicular line will have -1

every line perpendicular to the given line has a slope of -1

Step-by-step explanation:

Answer:

c

Step-by-step explanation:

The first and last expressions are identified as a limit that exists.

'In Mathematics, a limit is defined as a value that a function approaches the output for the given input values.'

According to the given problem,

For expression 1,

     [tex]\lim_{n \to4}\frac{x^{2}-x-12 }{2-x}[/tex]

⇒ [tex]\lim_{n \to4} \frac{x^{2}-4x+3x-12 }{4-x}[/tex]

⇒ [tex]\lim_{n \to4}\frac{-x(4-x)-3(4-x)}{4-x}[/tex]

⇒ [tex]\lim_{n \to4}\frac{(4-x)(-x-3)}{4-x}[/tex]

⇒ [tex]\lim_{n \to4 }(-x-3)[/tex]

Now, we put the value of x as 4

⇒ - 4 - 3

= -7

Therefore, the limit exists.

For the last expression,

    [tex]\lim_{x \to 2} \frac{x^{2}+3x-10 }{x^{2} -4}[/tex]

⇒ [tex]\lim_{x \to 2} \frac{x^{2}+5x - 2x-10 }{(x+4)(x-4)}[/tex]

⇒ [tex]\lim_{x \to2} \frac{x(x+5) -2(x+5)}{(x+4)(x-4)}[/tex]

⇒ [tex]\lim_{n \to 2} \frac{(x+5)(x-2)}{(x+4)(x-4)}[/tex]

Now, putting the value of x = 2 in the expression,

⇒ (2+5)(2-2) / (2+4)(2-4)

⇒ 7*0 / 6*(-2)

= 0

Therefore, the limit exists.

For the other expressions, we cannot factorize the numerator or the denominator to cancel out the denominator because of which if we put the values of x directly into the denominator without cancelling it out, the denominator would be zero, which means infinity because zero in the denominator of a fraction means infinity or undefined or does not exist.

Hence, we can conclude that expressions 1 and 6 are limits that exist.

Step-by-step explanation:

Answer:

So, a + b = 3 + 3 = 6

Hence,

There will be 6 marbles in the bag, 3 red and 3 blue.

Step-by-step explanation:

In this question probabilities are not given which should be given in order to calculate the number of marbles in the bag.

So, let's assume the probability that both marbles are red = 0.5

And probability that both marbles are blue = 0.5

Total Probability = 1

Furthermore, Let's suppose the bag contains

a number of red marbles and b number of blue marbles.

This problem includes the concepts of combination.

So,

[tex]\frac{_{2} C^{a} }{_{2} C^{a+b} }[/tex] = 0.5      Equation 1

[tex]\frac{_{2} C^{b} }{_{2} C^{a+b} }[/tex] = 0.5      Equation 2

Dividing Equation 1 and equation 2  we will get

[tex]\frac{_{2} C^{a} }{_{2} C^{b} }[/tex] = 1

It means, we can write:

[tex]_{2} C^{a} = _{2}C^{b}[/tex]

Hence, we can conclude that:

a = b

Now, from equation 1, we can write:

[tex]\frac{_{2} C^{a} }{_{2} C^{2a} }[/tex] = 0.5

Breaking down the combinations, we will get:

[tex]\frac{\frac{a!}{2! (a-2)!} }{\frac{2a!}{2! (2a - 2)!} }[/tex] = 0.5

[tex]\frac{a ( a-1)}{2a (2a-1)} = \frac{1}{5}[/tex]

(a-1)5 = 4a - 2

5a - 5 = 4a - 2

5a -4a = 5-2

a = 3

As, we know, a = b

So, a + b = 3 + 3 = 6

Hence,

There will be 6 marbles in the bag, 3 red and 3 blue.

Now this is a binomial probability distribution

[tex]P(X) = ^nC_x \times p^x \tmes (1 - p)^{n-x}\\\\P(3) = ^8C_3 \tims 0.20^3 \times (1 - 0.20)^5[/tex]

150π in^2/min.

Step-by-step explanation:

Area of circle A = πD^2/4

where D is the diameter of the circle.

now, taking differentiation w.r.t. to time t we get

dA/dt = π/4 ×2D×dD/dt

given dD/dt = 5in/min

therefore, dA/dt =  π/4×2×5×(20×12)

=π/4×600

Answer:

69.04

Step-by-step explanation:

Given that:

Mean (m) = 69.0

Standard deviation (s) = 2.8

Zscore = 0.2

Find the corresponding height (x) ;

Using the relation :

Zscore = (x - m) / s

0.2 = (x - 69.0) / 0.2

0.04 = x - 69.0

0.04 + 69.0 = x

69.04 = x

Hence, the height of a man with a Zscore of 0.2 is 69.04
