Answer:

1/169

Step-by-step explanation:

There are total 52 cards in deck. Also, there are 4 kings and 4 jacks in the deck.

Probability of choosing a king out of 4 kings and total there are 52 cards

∴ Ans1 = ⁴C₁/⁵²C₁ = 4/52 = 1/13

The cards are drawn with replacement so again there will be total 52 cards.

Probability of choosing a jack out of 4 jacks and total there are 52 cards

∴Ans2 = ⁴C₁/⁵²C₁ = 4/52 = 1/13

So, ans=Ans1 * Ans2 = 1/13 *1/13 = 1/169

Answer:

After 45.7 years

Step-by-step explanation:

∵ r = 1/2% per year

∵ P0 = $40

∵ Pn = $50

∵ Pn = P0 ( 1 + r/100)^n-1

∵ P0 is initial value , Pn is the value after n years , is the rate

∴ 50 = 40 (1 + 0.5/100)^n-1

∴ 50/40 = (1.005)^n-1

∴ 1.25 = (1.005)^n-1 ⇒ insert ln in both sides

∴ ln(1.25) = (n-1)ln(1.005)

∴ n - 1 = ln(1.25)/ln(1.005)

∴ n = ln(1.25)/ln(1.005)  + 1 = 45.7 years

Answer:

C

Step-by-step explanation:

Let's break down the definitions.

Median = the middle value in the number set

So yes this is an appropriate measure of center.

Mode = the most common value in the number set

Since this can be any number, this isn't an appropriate measure of center.

Mean = average

So yes this can also be an appropriate measure of center.

Answer:

(1) Observe the attached image

(2) [tex]S = \$4,000[/tex]

(3) [tex]x = \$90,000[/tex]

(4) [tex]S = 2100[/tex]

Step-by-step explanation:

(1) Let's call S the salary for the month the seller wins.

Let's call x the amount of dollars reached by the sales of that month.

The seller earns a base salary of $ 2100 per month.

Then, if x> 42,000 he wins a commission of 5% on sales.

Then the equation modeling this situation is:

[tex]S =\left\{{{0.05(x-42,000)+2100\ if\ x>42,000} \atop{2,100\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ if\ 0\leq x\leq42,000}}\right.[/tex]

The graph of the function is shown in the attached image.

(2) If x = 80,000, then your salary was:

[tex]S = 0.05(80000-42000) +2100\\\\S = \$4,000[/tex]

(3) If S was 4500 and we want to find x then we equal S to 4500 and solve for x.

[tex]S = 4,500 = 0.05(x-42,000) + 2,100\\\\\frac{2,400}{0.05} = (x-42,000)\\\\x = \frac{2400}{0.05} +42,000\\\\x = \$90,000[/tex]

(4) S (25000) means that x equals 25000. Since x represents sales, this means that during the month, the seller only reached $ 25,000.

Then [tex]x <42000[/tex]

Therefore [tex]S = 2100[/tex].

Rolling a six on a die twice in a row is an example of independent events, as the outcome of one roll doesn't affect the outcome of the other, confirmed by applying the Multiplication Rule for independent events in probability theory.

The question is asking whether rolling a six on a die twice in a row is considered a dependent or independent event. In probability theory, two events are considered independent if the occurrence of one does not affect the outcome of the other. In this case, rolling a die twice, the outcome of the first roll does not affect the outcome of the second roll. This is because each roll is a separate event and the die does not have a 'memory' of the previous roll.

Using the Multiplication Rule for independent events, we can confirm this. The Multiplication Rule states that the probability of two independent events happening together (A and B) is the product of their individual probabilities (P(A AND B) = P(A) * P(B)).

Applying this rule to our situation, the probability of rolling a six (A) and then rolling another six (B) is the product of the probabilities of each of these events happening on their own. This is (1/6)*(1/6) = 1/36. The result confirms that the two rolls are, indeed, independent events.

Answer:it would be infinalty many

Step-by-step explanation:

The statement "There are infinitely many solutions" is true about the solution to the set of equations, as the lines represented are coincident.

To determine the solution to the set of equations, we can solve them simultaneously.

Given:

- Equation of Line A: 3x + 3y = 12

- Equation of Line B: x + y = 4

To find the solution, we can use methods like substitution or elimination. Here, let's use the elimination method:

Multiply the second equation by 3 to match the coefficients of \(y\) in both equations:

3(x + y) = 3(4)

3x + 3y = 12

Now, we can see that both equations represent the same line, so they are coincident or overlapping. Therefore, there are infinitely many solutions.

Hence, the statement "There are infinitely many solutions" is true about the solution to the set of equations.

Rewrite it in the form; a^2 - b^2, where a = 5x and b = 6

(5x)^2 - 6^2

Use the Difference of Squares: a^2 - b^2 = (a + b)(a - b)

(5x + 6)(5x - 6)

To factor 25x^2-36 completely, we use the difference of squares formula which gives us the factorization (5x + 6)(5x - 6).

To factor the expression 25x^2-36 completely, we can use the difference of squares formula. This formula states that a^2 - b^2 can be factored as (a + b)(a - b). In this case, our 'a' value is 5x and our 'b' value is 6. So we can factor 25x^2-36 as (5x + 6)(5x - 6).

Answer:

the Answer is irrational

Step-by-step explanation:

Answer:

Hi,

These graphs looks like a smooth curve due to the asymptotes,or a straight line to which the graph of the function gets arbitrarily close.

Step-by-step explanation:

Rational functions are in the form of y= f(x) where f(x) is a rational expression. The graphs of rational functions are drawn by first finding the asymptotes and the intercepts. The graph follows a smooth curve that connects the points without crossing the vertical asymptotes. The line is shaped in that shape to satisfy the vertical line test.

Step-by-step explanation:

Your answer should be A.

Answer:

The answer is C because both ordered pair when they are substituted into the equation, both sides equal to each other.

Explanation:

All you do is substitute. (x,y)

A:

Substitute

11 = 8(1) + 3

Multiply the inside parentheses by the outside number

11 = 8 + 3

Add them together to get the solution.

11 = 11

Both sides equal to each other so that means that it is a solution to the equation.

B:

Substitute

-5 = 8(-1) + 3

Multiply the inside parentheses by the outside number

-5 = -8 + 3

Add them together to get the solution.

-5 = -5

Both sides equal to each other so that means that it is also a solution to the equation.

D:

Both ordered pair gives you an equal solution to both sides.

Look at the picture.

We connect two congruent trapezoids as in the picture.

We created a parallelogram with a base length of b₁ + b₂ and a height h equal to the height of the trapezoid.

The formula of an area of a parallelogram:

[tex]A_p=(base)(height)\to A_p=(b_1+b_2)h[/tex]

The area of the trapezoid is half of the parallelogram area.

Therefore we have the formula of an area of trapezoid:

[tex]A_t=\dfrac{(b_1+b_2)h}{2}[/tex]

Therefore we need to be added the bases of a trapezoid.

Answer: first option.

Step-by-step explanation:

To solve this problem you must plug the function h(x) into the function g(x):

[tex]g(x)=\sqrt{(2x-8)-4}[/tex]

Now you must simplify by adding like terms, as following:

[tex]g(h(x))=\sqrt{2x-12}[/tex]

Substitute x=10 into the fucntion. Therefore, you obtain the following result:

[tex]g(h(10))=\sqrt{2(10)-12}[/tex]

[tex]g(h(10))=2\sqrt{2}[/tex]

Answer:

The correct answer is first option  2√2

Step-by-step explanation:

It is given that, g(x) = √(x - 4) and h(x) = 2x - 8

To find g(h(x))

We have g(x) = √(x - 4) and h(x) = 2x - 8

h(x) = 2x - 8

g(h(x)) =  √((2x - 8)- 4) = √(2x - 12)

To find the value of g(h(10))

g(h(x)) = √(2x - 12)

g(h(10)) = √(2*10 - 12) =√(20 -12) =√8 = 2√2

Therefore the correct answer is first option  2√2

Answer:

$65

Step-by-step explanation:

Let's add up the flat rate and the cost of four tires:

flat rate + 4($122.57/tire) = $555.28

We are to solve for "flat rate."  First, multiply out 4($122.57/tire), obtaining a tire cost of $490.28 total.  Subtracting this tire cost from the $555.28 Janette paid the shop, we get "flat rate" = $555.28 - $490.28, or $65.

Thus, the installation charge ("flat rate") must have been $65.
