Answer:

The answer is 91 inches or 7ft 7in.

Answer: True.

Step-by-step explanation:

Here we have the number:

26,59,360

To find the place value of the 5, we first need to count the number of decimals at the right of the 5 (until we reach the decimal point)

For this case, at the left of the 5 we have 4 decimals (9, 3, 6 and 0)

Then the place value of the 5 in that number will be 10^4

this is equal to:

10^4 = (10)*(10)*(10)*(10) = 10,000

This means that the place value of the 5 is then thousand.

Then the statement is true.

Answer: 360

Step-by-step explanation:

Given

the side length of the cube [tex]a=\frac{1}{4}\ inch[/tex]

The dimension of the box is [tex]1\times3 \frac{3}{4}\times 1 \frac{1}{2}=1\times\frac{15}{4}\times\frac{3}{2}\ inch^3[/tex]

the volume of each cube [tex]=a^3=(\frac{1}{4})^3[/tex]

No. of cubes that can be fit into the box [tex]=\dfrac{\text{vol. of box}}{\text{vol. of each cube}}[/tex]

[tex]\Rightarrow \dfrac{1\times \frac{15}{4}\times\frac{3}{2}}{\frac{1}{4}\times\frac{1}{4}\times\frac{1}{4}}=360[/tex]

Therefore 360 cubes can be fit into the box

Answer:

Probability of Four of a Kind

The probability of being dealt four of a kind is 0.0002400960384. On average, four of a kind is dealt one time in every 4,165 deals.

Probability of Two Pair

On average, players get two pair about one time in every 21 deals.

Step-by-step explanation:

Probability of Four of a Kind

Let's execute the analytical plan described above to find the probability of four of a kind.

First, we count the number of five-card hands that can be dealt from a standard deck of 52 cards. This is a combination problem. The number of combinations is n! / r!(n - r)!. We have 52 cards in the deck so n = 52. And we want to arrange them in unordered groups of 5, so r = 5. Thus, the number of combinations is:

52C5 = 52! / 5!(52 - 5)! = 52! / 5!47! = 2,598,960

Hence, there are 2,598,960 distinct poker hands.

We count the number of ways that five cards can be dealt to produce four of a kind. It requires three independent choices to produce four of a kind:

Choose the rank of the card that appears four times in the hand. A playing card can have a rank of 2, 3, 4, 5, 6, 7, 8, 9, 10, jack, queen, king, or ace. For four of a kind, we choose 1 rank from a set of 13 ranks. The number of ways to do this is 13C1.

Choose one rank for the fifth card. There are 12 remaining ranks, from which we choose one. The number of ways to do this is 12C1.

Choose a suit for the fifth card. There are four suits, from which we choose one. The number of ways to do this is 4C1.

The number of ways to produce four of a kind (Num4) is equal to the product of the number of ways to make each independent choice. Therefore,

Num4 = 13C1 * 12C1 * 4C1 = 13 * 12 * 4 = 624

Conclusion: There are 624 different ways to deal a poker hand that can be classified as four of a kind.

Finally, we compute the probability. There are 2,598,960 unique poker hands. Of those, 624 are four of a kind. Therefore, the probability of being dealt four of a kind (P4) is:

P4 = 624 / 2,598,960 = 0.0002400960384

The probability of being dealt four of a kind is 0.0002400960384. On average, four of a kind is dealt one time in every 4,165 deals.

Probability of Two Pair

To find the probability for two pair, we execute the same analytical plan that we've used to compute the other probabilities.

There are 2,598,960 distinct poker hands.

Next, count the number of ways that five cards can be dealt to produce two pair. It requires five independent choices to produce two pair:

Choose the rank for cards of matching rank. A playing card can have a rank of 2, 3, 4, 5, 6, 7, 8, 9, 10, jack, queen, king, or ace. For two pair, we choose 2 ranks from a set of 13 ranks. The number of ways to do this is 13C2.

Choose the rank of the remaining non-matching card. There are 11 remaining ranks, from which we choose one. The number of ways to do this is 11C1.

Choose suits for the first two-card combination. There are four suits, from which we choose two. The number of ways to do this is 4C2.

Choose suits for the second two-card combination. There are four suits, from which we choose two. The number of ways to do this is 4C2.

Choose a suit for the non-matching card. There are four suits, from which we choose one. The number of ways to do this is 4C1.

The number of ways to produce two pair (Numtp) is equal to the product of the number of ways to make each independent choice. Therefore,

Numtp = 13C2 * 11C1 * 4C2 * 4C2 * 4C1

Numtp = 78 * 11 * 6 * 6 * 4 = 123,552

Finally, compute the probability. There are 2,598,960 unique poker hands. Of those, 123,552 are two pair. Therefore, the probability of being dealt two pair (Ptp) is:

Ptp = 123,552 / 2,598,960 = 0.04753901561

On average, players get two pair about one time in every 21 deals.

Answer:6/10

Step-by-step explanation:

The value of sin(A) is  0.6 or about 36.87°.

Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.

we are given that;

The two triangles

Now,

To find the value of sin(A), you need to use the sine function formula, which is:

sin(A) = opposite/hypotenuse

The opposite side of angle A is YN and the hypotenuse is AN. You can use the Pythagorean theorem to find the length of AN:

AN 2 = AY 2 + YN 2 AN 2 = 8 2 + 6 2 AN 2 = 64 + 36 AN 2 = 100 AN = √100 AN = 10

Therefore, sin(A) = YN/AN = 6/10 = 0.6

You can also use a calculator to find the angle A using the inverse sine function:

sin −1 (0.6) = A A ≈ 36.87°

Therefore, by trigonometric ratios the answer will be 0.6 or about 36.87°.

Answer:

Team A has 16 points

Team B has 4 points

Step-by-step explanation:

let A = 12 + B

also, let A = 4B

therefore, since A = A we can say that 12 + B = 4B

12 + B = 4B

12 = 3B

B = 4

A = 12 + 4 or 16

Step-by-step explanation:

when you are asked for a unit rate it is always something like this

$5 /pound or  2.2 pounds/ kg  

We set up the equation like this:

$13.50/3 pounds

So, for this we need to get 3 pounds down to 1 pound. Also, to make the eqaution balance we need to divide $13,50 by 3 too!

So, the unit rate is $4.5/pound or $4.5 per pound.
