As a fraction, it is equal to exactly 792/(2,598,960)

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

Explanation:

The king of spades must be in the hand, and we can pick any other king. There are 3 ways to pick the other king. Then there are 4 C 2 = 6 ways to pick the two queens. The 4C2 refers to the nCr notation. Or you could use Pascal's Triangle.

Overall, there are 3*6 = 18 ways to pick the king of spades, another king, and exactly 2 queens.

Then we have one more card to pick that isn't a king nor a queen. There are 4+4 = 8 cards that are either a king or queen, leaving 52-8 = 44 cards that are neither.

So there are 18*44 = 792 ways to pick a king of spades, another king, exactly 2 queens, and some other card that isn't a king nor queen.

This is out of 52C5 = 2,598,960 possible five card hands.

The probability we're after is roughly 792/(2,598,960) = 0.0003047

Side note: order does not matter with card hands.

Answer:

  $33 per hour

Step-by-step explanation:

"Time and a half" means the overtime rate is 1 1/2 times the base rate.

  overtime rate = (1 1/2) × $22/hour = $(22 +1/2(22))/hour = $33/hour

The correct overtime rate is $33 per hour.

Using the binomial distribution, it is found that there is a 0.056 = 5.6% probability that more than 7 will make a purchase.

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem:

The probability that more than 7 will make a purchase is given by:

P(X > 7) = P(X = 8) + P(X = 9) + P(X = 10) + P(X = 11) + P(X = 12).

Hence:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 8) = C_{12,8}.(0.4)^{8}.(0.6)^{4} = 0.042[/tex]

[tex]P(X = 9) = C_{12,9}.(0.4)^{9}.(0.6)^{3} = 0.012[/tex]

[tex]P(X = 10) = C_{12,10}.(0.4)^{10}.(0.6)^{2} = 0.02[/tex]

[tex]P(X = 11) = C_{12,11}.(0.4)^{11}.(0.6)^{1} \approx 0[/tex]

[tex]P(X = 12) = C_{12,12}.(0.4)^{12}.(0.6)^{0} \approx 0[/tex]

Then:

P(X > 7) = P(X = 8) + P(X = 9) + P(X = 10) + P(X = 11) + P(X = 12) = 0.042 + 0.012 + 0.02 + 0 + 0 = 0.056.

0.056 = 5.6% probability that more than 7 will make a purchase.

so what we're going to do is, find the cost of wrapping paper per foot,

6.03 divided by 9 = 0.67

now we're going to convert the 9ft into yards,

1 yard= 3ft so, there are 3 yards.

now that we know that there are 3 ft in one yard, we are going to multiply 0.67 by 3

0.67x3= 2.01

so, we got $2.01 per yard

Answer: b+95+34=180, b+129=180, 51

Step-by-step explanation:

b+95+34=180 works because the angles add to form a straight angle.

From this, we can obtain b+129=180 by adding the two constants.

Subtracting 129 from both sides, we get b=51.

The slope of the h(x) is 4x as the value of x increases the slope of h(x) will approach to the infinity.

The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.

The functions are given below.

[tex]\rm f(x) = 4x+ 50\\\\ g(x) = 3x - 4 \\\\h(x) = 2x^2+ 9x- 4[/tex]

The slope of the f(x) and g(x) will be 4 and 3 respectively.

And the slope of the h(x) is 4x as the value of x increases the slope of h(x) will approach to the infinity.

Answer:

  24.3°

Step-by-step explanation:

A suitable calculator can add the vectors directly. (See attached.) In this calculation, bearing angles are measured clockwise from north, so the initial vector has an associated angle of 0 degrees.

__

We can find the angle of interest by considering the distances north and east that city C is from city B. The relevant trig functions are ...

  Sin = Opposite/Hypotenuse

  Cos = Adjacent/Hypotenuse

  Tan = Opposite/Adjacent

__

The direct distance from B to C is the hypotenuse of a right triangle whose right angle is at point "D" due north of B and due west of C. The distances of interest are ...

  sin(57°) = DC/BC

  DC = BC·sin(57°) = (108 km)sin(57°) ≈ 90.5764 km

  cos(57°) = BD/BC

  BD = BC·cos(57°) = (108 km)cos(57°) ≈ 58.8210 km

__

And the angle of interest can be found from ...

  tan(θ) = DC/AD = (90.5764 km)/(142 km +58.8210 km) ≈ 0.451031

  θ = arctan(0.451031) ≈ 24.3°

The pilot could have flown on a bearing of 24.3° to get to city C directly from city A.

_____

Additional comment

We can ignore the fact that bearing angles are measured CW from north, while conventional angles on a Cartesian plane are measured CCW from "east" (+x). Each coordinate system can be mapped to the other by flipping the map over along a NE-SW line (y=x), aligning the +x axis with north and the +y axis with east.

The diagram we used in working this problem is shown in the second attachment.

Answer:

25

If you divide by eight, it is equivalent to five cords per minutes.

Now you know that she plays five cords per minute, right?

So you want to multiply five by five, because she plays a total of five minutes.

The percentage of the total cost of 23 separate tickets that George saves by buying a season ticket is 23%.

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

As the cost of the separate ticket is £24, and there are a total of 23 games, therefore, the total cost of the 23 games separate ticket can be written as,

=  £24 × 23

=  £552

Now, the cost of the season ticket is £425, therefore, the percentage of the total cost of 23 separate tickets that George saves by buying a season ticket can be written as,

[tex]\rm Percentage = \dfrac{\text{Total cost of 23 seperate ticket}-\text{Cost of season ticket}}{\text{Total cost of 23 seperate ticket}} \times 100\%[/tex]

[tex]\rm Percentage = \dfrac{552-425}{552} \times 100\% = \dfrac{127}{552} \times 100\% = 23\%[/tex]

Hence, the percentage of the total cost of 23 separate tickets that George saves by buying a season ticket is 23%.

Answer:

94.1 cm^3 to nearest tenth.

Step-by-step explanation:

Each hour 100 - 10 = 90% of the gas remains.

90% = 0.90.

At 0 hours the volume = 300 cm^3

The equation is

Amount (V) after x hours = 300(0.90)^x.

The amount after 11 hours:

V = 300(0.90)^11

= 94.14

Answer:

y = 300(0.9)^x
