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

Explanation:

Four-of-a-kind is when you get four cards of the same value. One example is if we got four aces. Any four-of-a-kind already has two pairs built into it. I'm assuming your teacher wants four-of-a-kind and another different pair (we'll have 6 pairs all together).

In any suit there are 13 unique cards. So there are 13 choices to fill the first four slots to set up the four-of-a-kind.

-------------

After the four-of-a-kind is formed, we have 13-1 = 12 unique cards left in any given suit. Once that fifth card is chosen, we then have 4 C 2 = 6 ways to select that final card such that we get another pair. I'm using the nCr combination formula since order doesn't matter. The steps to calculating this value (and the other nCr value mentioned later) is shown in the attached image below.

Multiplying those values gets us 13*12*6 = 936 different six card hands such that we get four-of-a-kind and a different pair.

-------------

This is out of 52 C 6 = 20,358,520 different six card hands.

Divide the two values found

936/(20,358,520) = 0.00004597583714

Answer:

220 cm²

Step-by-step explanation:

area of rectangle:

Length * Width

18 * 11

198 cm²

Triangle area:

1/2 * base * height

1/2 * (18-7)(15-11)

1/2 * 11 * 4

22 cm²

So total area: 198 cm² + 22 cm² = 220 cm²

Answer:

45

Step-by-step explanation:

-45 + 30 gives you -15. When subtractinf a negative number, it actually turning into addition/positive. This changes it into -15 + 60, which is 45.

Answer: 45

Step-by-step explanation:

-45+30-(-60)=
First, times the negative 60 with the negative outside the parenthesis.

-45+30+60

60+30=90

90-45=45

Step-by-step explanation:

Answer: 39

Step-by-step explanation: We have to move the decimal one place to the right to make 1.2 a whole number, so 12. You do the same thing to 46.8, so you get 468. Then you divide from there. 12 can go into 46 3 times. 12 x 3 = 36. you subtract to get 10, then bring down your 8, to get a new number of 108. 12 can go into 108 9 times. 12 x 9 = 108. Then you have a remainder of 0. Your product is 39.

Approximately 0.2200 or 22.00% of the exam scores are between 82.2 and 85.6.

To find the proportion of exam scores between 82.2 and 85.6, we need to calculate the z-scores for both values and then use the standard normal distribution table (also known as the z-table) to find the proportion.

The z-score for a value x in a normal distribution with mean μ and standard deviation σ is given by the formula:

z = (x - μ) / σ

where x is the value, μ is the mean, and σ is the standard deviation.

Let's calculate the z-scores:

For x = 82.2:

z₁ = (82.2 - 80.2) / 4 = 2 / 4 = 0.5

For x = 85.6:

z₂ = (85.6 - 80.2) / 4 = 5.4 / 4 = 1.35

Now, we can find the proportion of scores between these z-scores using the z-table. The table gives us the cumulative probability up to a certain z-score.

From the z-table, the cumulative probability for z₁ = 0.5 is approximately 0.6915, and the cumulative probability for z₂ = 1.35 is approximately 0.9115.

Now, we can find the proportion of scores between these two z-scores:

Proportion = P(0.5 ≤ z ≤ 1.35)

= P(z ≤ 1.35) - P(z ≤ 0.5)

= 0.9115 - 0.6915

≈ 0.2200

So, approximately 0.2200 or 22.00% of the exam scores are between 82.2 and 85.6.

= 2.5 km (approx.)

2.5 km of garden hose are stocked by the store.

Answer:

3.5 gallons of gas

Step-by-step explanation:

g = 3.5 gallons of gas.

The car used "3.5" gallons of gas.

Answer:

answer d and e

Step-by-step explanation:

First, you need to figure out the radius of B.

As radius of A is 6 in, 20% of 6in would be 1.2in. So total radius of B = 6+1.2 = 7.2

Now you get the radius of B, calculate th area of B using the formula πr^2.

= π(7.2)^2 = 162.86 = area of B

Now, all answers except D and E is smaller than B. So, the answer would be D and E.

Answer:

  A, E

Step-by-step explanation:

The radius of Circle B is 20% greater than 6 inches, so is ...

  r = (6 in)(1 +20%) = 1.2×6 in = 7.2 in

The area of Circle B is ...

  A = πr²

  A = π(7.2 in)² ≈ 162.86 in²

The offered answer choices (and the area of Circle B) in order from least to greatest are ...

  [B]51.84, [C]113.04, [F]148.49, [D]162.78,

  (circle B)162.86,

  [A}189.31, [E]203.15

Choices A and E are greater than Circle B's area.

Answer:

One notebook is $3.00

Step-by-step explanation:

3x + 2y = $12

1x + 3y = $11

Add -3y to the second equation

x = 11 - 3y

Substitute ( 11 - 3y ) for x in 3x + 2y = 12

3 ( 11 - 3y ) + 2y = 12

33 - 9y + 2y = 12

33 - 7y = 12

Add -33 to each side

-7y = -21

Divide each side by -7

y = 3

substitute 3 for y in x = 11 - 3y

x = 11 - 3(3)

x = 11 -9

x = 2

One notebook is $3.00

Let k = 1, for a start. By definition of the Laplace transform,

[tex]\displaystyle F(s) = \int_0^\infty f(t) e^{-st} \, dt[/tex]

Differentiate both sides with respect to s :

[tex]\displaystyle F'(s) = \frac{d}{ds} \int_0^\infty f(t) e^{-st} \, dt[/tex]

[tex]\displaystyle F'(s) = \int_0^\infty \frac{\partial}{\partial s}  \left[f(t) e^{-st}\right] \, dt[/tex]

[tex]\displaystyle F'(s) = \int_0^\infty -t f(t) e^{-st} \, dt[/tex]

so that [tex]t f(t) \leftrightarrow (-1)^1 F^{(1)}(s) = -F'(s)[/tex] is indeed true.

Suppose the claim is true for arbitrary integer k = n, which is to say that [tex]t^n f(t) \leftrightarrow (-1)^n F^{(n)}(s)[/tex]. Then if k = n + 1, we have

[tex]F^{(n+1)}(s) = \dfrac{d}{ds} F^{(n)}(s)[/tex]

Consider the two cases:

• If k = n + 1 is even, then n is odd, so

[tex](-1)^n F^{(n)}(s) = -F^{(n)}(s) \leftrightarrow t^n f(t)[/tex]

and it follows that

[tex]F^{(n+1)}(s) = \displaystyle \frac{d}{ds} \left[-\int_0^\infty t^n f(t) e^{-st} \, dt \right][/tex]

[tex]F^{(n+1)}(s) = \displaystyle -\int_0^\infty \frac{\partial}{\partial s}\left[ t^n f(t) e^{-st} \right] \, dt[/tex]

[tex]F^{(n+1)}(s) = \displaystyle \frac{d}{ds} \left[-\int_0^\infty t^n f(t) e^{-st} \, dt \right][/tex]

[tex]F^{(n+1)}(s) = \displaystyle \int_0^\infty t^{n+1} f(t) e^{-st} \, dt[/tex]

[tex]\implies F^{(n+1)}(s) = (-1)^{n+1} F^{(n+1)}(s) \leftrightarrow t^{n+1}f(t)[/tex]

• Otherwise, if k = n + 1 is odd, then n is even, so

[tex](-1)^n F^{(n)}(s) = F^{(n)}(s) \leftrightarrow t^n f(t)[/tex]

The rest of the proof is the same as the previous case.

So we've proved the claim by induction:

• [tex]t f(t) \leftrightarrow -F(s)[/tex], and

• [tex]\bigg(t^n f(t) \leftrightarrow (-1)^n F^{(n)}(s)\bigg) \implies \bigg(t^{n+1} f(t) \leftrightarrow (-1)^{n+1} F^{(n+1)}(s)\bigg)[/tex]

We have :

s - 39⁰+ s - 9⁰ = s + 29⁰

s + s - s = 29⁰ + 9⁰ + 39⁰

s = 77⁰

Answer: 77⁰

[tex] \boxed{ \tt\longrightarrow \: Area \: Of \: Shaded \: region \: =\boxed{ \tt 39 \: in²}}[/tex]

Step-by-step explanation:

Given:

The Dimensions of Parallelogram are 12 in.(Base) and 7 in.(Height)

And,

The Dimensions of Rectangle are 9 in.(Length) and 5 in.(Breadth).

To Find:

The Area of Shaded region

Solution:

When the dimensions of parallelogram and the dimensions of rectangle are given, we need to find the Shaded region using this formula:

[tex] \boxed{\tt \longrightarrow Area = (Parallelogram - Rectangle)}[/tex]

We know that the formula of Parallelogram is base*height[b×h] and the formula of rectangle is length*breadth[l*b] .

[tex] \tt\longrightarrow \: Area =B×h-l×b [/tex]

Put their values accordingly:

[tex]\longrightarrow \tt Area = (12 \times 7 - 9 \times 5)in {}^{2} [/tex]

Simplify it.

[Follow BODMAS Rule strictly while simplifying]

[tex] \tt\longrightarrow \: Area = (84 - 45 ) in {}^{2} [/tex]

[tex] \tt\longrightarrow \: Area = 39 \: {in}^{2} [/tex]

Hence, the Area of Shaded region would be 39 in² or 39 sq. in. .
