Answer:

1022 of $10 tickets, 1326 of $20 tickets, 948 of VIP $30 tickets

Answer:

$10 tickets = 1,119

$20 tickets = 1,310

$30 tickets = 893

Step-by-step explanation:

x = $10 tickets, y = $20 tickets, z = $30 tickets

10x + 20y + 30z = 64,180

x + y + z = 3,322

y = 191 + x

therefore;

10x + 20(191+x) + 30z = 64,180     eqn 1

x + (191 + x) + z = 3,322         eqn 2

make z the subject of eqn 2

z = 3,322 - x - (191 + x)

z = 3,322 - 191 - x - x

z = 3131 - 2x

put z in eqn 1

10x + 20(191+x) + 30(3131 - 2x) = 64,180

10x + 3820 + 20x + 93,930 - 60x = 64,180

10x + 20x - 60x = 64,180 - 3820 - 93,930

-30x         =      -33,570

x      =   1,119

put x = 1,119 in z

z = 3131 - 2(1119)

z = 893

put x = 1,119 in y

y = 191 + 1119

  = 1,310

10(1119) + 20(1310) + 30(893) = 64,180

1119 + 1310 + 893 = 3,322

Answer:

15 : 4

Step-by-step explanation:

Given that,

→ 4 lionesses

→ 15 cubs

Then the ratio of cubs to lionesses,

→ x = No. of cubs : No. of lionesses

→ [ x = 15 : 4 ]

Hence, the ratio is 15 : 4.

The expression 64a³ - 8b³ can be factored as 8 (8a³ - b³).

Given a cubic expression.

64a³ - 8b³

We have to factor this expression.

Factoring is the method of taking the common terms outside of an expression which contains more than one terms.

This is also a form of simplification.

Consider the expression,

64a³ - 8b³

Here 8 is a common factor of both 64a³ and 8b³.

64a³ - 8b³ = 8 (8a³ - b³)

Hence the factored form of the given expression is 64a³ - 8b³ = 8 (8a³ - b³).

Answer:

Q=-8

Step-by-step explanation:

Q-2-6

The required probability is 0.325 or 32.5%.

Event A and B are independent. Suppose P(B) = 0.4 and P(A and B) = 0.13.

Given: P(B) = 0.4P(A and B) = 0.13

Formula used: We know that when two events A and B are independent, then P(A and B) = P(A) × P(B)

Hence, the formula for finding P(A) can be given by:P(A) = P(A and B) / P(B)

Now, let's put the given values in the formula:P(A) = 0.13 / 0.4P(A) = 0.325

So, the probability of event A is 0.325 or 32.5% (approx).

The altimeter will indicate a reading of 22,697 feet.

Standard deviation is a measure of variability in a dataset. It is calculated by taking the square root of the variance, which is the average of the squared differences from the mean. This measure indicates how much variation exists in a dataset.

If you are at an altitude of Flight Level 230 (23,000 feet) and forget to set your altimeter to the local altimeter setting during descent, your altimeter will indicate different readings depending on the field elevation and the local altimeter setting.

To calculate the difference between the two, we use the standard deviation formula. Specifically, we calculate the difference between the local altimeter setting and the field elevation, and subtract that difference from the Flight Level. The standard deviation formula then looks like this:

Flight Level - (Local Altimeter Setting - Field Elevation)

In our example, the equation would look like this:

23,000 - (30.02 - 303) = 22,697

It is important to note that when making such calculations, the Flight Level should always be expressed in feet, rather than in thousands of feet.

By using the standard deviation formula and keeping track of settings like local altimeter setting and field elevation, pilots can ensure that their altimeter readings are accurate and that their aircraft will land safely

Answer:

1) The ship is closer

2) 675.73 m

Step-by-step explanation:

1) The given parameters are;

The initial angle between the ship's course and the lighthouse = 32°

The final angle between the ship's course and the lighthouse = 72°

The distance traveled by the sip between he two positions = 1500 m

Therefore we have a triangle formed between the distance covered by the ship and the two distances of the ship from the lighthouse, a and b

Where;

a = The initial distance fro the lighthouse

b = The final distance fro the lighthouse

The angles of the triangle are

32°, (180 - 72) = 108° and 180 - 32 - 108 = 40°

By sine rule we have;

1500/(sin(40)) = a/(sin(108)) = b/(sin(32)) =

Therefore, a = sin(108°) × 1500/(sin(40°)) = 2219.37 m

b = (sin(32°)) × 1500/(sin(40°)) = 1236.61 m

Therefore, a  > b

The initial distance fro the lighthouse > The final distance fro the lighthouse, which shows that the ship is closer

2) By cosine rule we have

a² = b² + c² - 2× b×c×cos(A)

Where the given measurements by Kendra are;

410 m and 805 m with an included (in between) angle of 57°, we have;

Let b = 410 m, c = 805 m, and A  = 57°, we have;

a² = 410^2 + 805^2 - 2× 410×805×cos(57 degrees) = 456608.77 m²

a = The length of the stream = 675.73 m.

Answer:

chatGPT

Step-by-step explanation:

Let's denote the speed of each car as v, and the distance that Car A travels as d. Then we can set up two equations based on the information given:

d = v * (12/60) (since Car A reaches its destination in 12 minutes)

d + 4 = v * (18/60) (since Car B travels 4 miles farther than Car A and reaches its destination in 18 minutes)

Simplifying the equations by multiplying both sides by 60 (to convert the minutes to hours) and canceling out v, we get:

12v = 60d

18v = 60d + 240

Subtracting the first equation from the second, we get:

6v = 240

Therefore:

v = 240/6 = 40

So the cars travel at a speed of 40 miles per hour.

Multiplicative

8/9 = 9/8

12/15 = 15/12

-6 = -1/6

10 = 1/10

Step-by-step explanation:

an additive inverse is a number you must add to another number to get 0

(think of it as the negative version of the number)

{but WHY? In math, you can imagine comparing numbers on a number line. If we are finding the opposite of a number, we want to find the same distance from 0, but on the opposite side of 0. So, 2 would be two to the right of 0, -2 would be two to the left of 0}

-2 + 2 = 0

18 - 18 = 0

-30 + 30 = 0

2/5 - 2/5 = 0

a multiplicative inverse is a number that you multiply by another number to get 1.

We are finding the "reciprocal" of a number; you are essentially flipping it as a fraction

(reciprocal of 2 = 1/2  {remember, 2 is the same thing as 2/1 }   ; reciprocal of 1 / 8 = 8)

note: reciprocal is being used interchangeably with multiplicative inverse here

8/9 · 9/8 = 1

12/15 · 15/12 = 1

-6 · -1/6 = 1                     {-6  = -6/1}

10 · 1/10 = 1                    {10 = 10/1}

As per the given data the graph of the function is given

Here we have to determine the limit at the indicated value of a, if it was exists.

You may have found the limit from one side instead of from both sides as notated.

Now we have to find:

\($\lim _{x \rightarrow a} f(x)$\) when a = 1

We find the left hand side limit and the right hand side limit at a = 1

So,

The Left hand limit is \($\lim _{\mathrm{x} \rightarrow 1^{-}} \mathrm{f}(\mathrm{x})=\frac{3}{2}$\)

The Right hand limit is \($\lim _{x \rightarrow 1^{+}}\) f(x) = 3

Here \($\lim _{x \rightarrow 1^{-}} f(x) \neq \lim _{x \rightarrow 1^{+}} f(x)$\)

Hence \($\lim _{x \rightarrow a}\) f(x) = DNE

From the graph we find the left hand limit and the right hand limit:

If Left hand limit = Right hand limit then limit exist

If then Left hand limit ≠ Right hand limit then limit does not exist.

Sampling Distribution:

A statistical sampling distribution is a type of probability distribution constructed by drawing a large number of random samples of a specified size from the same population. These distributions are useful for understanding how sample statistics vary from sample to sample. Mean of sampling distribution:

The distribution of the values of the sample mean (x- bar) in replicate samples is called the x -bar sampling distribution.

Answer:

1997.08 pounds at the beginning of 6 years.

Step-by-step explanation:

If you start at 2100 pounds, and it depreciates by .01 every year, you would start by doing this. It wouldn't just be subtracting 21 each year because the value depreciates and 1% would come off the new depreciated value each year.

1st year - 2100*.01 = 21  

2100-21 = 2079

2nd year - 2079*.01 = 20.79

2079 - 20.79 = 2058.21

3rd year - 2058.21*.01 = 20.58

2058.21-20.58 = 2037.63

4th year - 2037.63*.01 = 20.38

2037.63-20.38 = 2017.25

5th year - 2017.25*.01 = 20.17

2017.25 - 20.17 = 1997.08

6th year - at the beginning of the 6th year, it would be worth 1997.08.

At the end of the 6th year, it would be: 1997.08*.01 = 19.97.  1997.08-19.97 = 1977.11
