Answer: 9 first-class tickets and 3 coach tickets

Step-by-step explanation:

Let's set up a systems of equation because we have two different values involved: first-class and coach.

f + c = 12

350f + 1080c = 6390

For ease of the equation, let's use the first equation to isolate a variable and plug it into the second one. We'll isolate f:

f = 12 - c

350(12 - c) + 1080c = 6390

c = 3

Now, plug in 3 for the first equation, and f = 9.

There are 9 first-class tickets and 3 coach tickets.

Answer:

First of all, this question is not complete. So, we will be hypothetically create two accounts and try to choose the one with the greater profit.

Choice 1 = X = Final Amount after 12 years = $5600

Choice 2 = Y = Final Amount after 12 years = $6285.50

Hence, Lorena should choose choice 2, as it gives more profit over than choice 1.

Step-by-step explanation:

First of all, this question is not complete. So, we will be hypothetically create two accounts and try to choose the one with the greater profit.

Initial Deposit Amount = $3500

Time period = 12 years

Let's Suppose Lorena has two X and Y choices of accounts at H-town Bank.

X = simple interest of 5% over the initial amount for 12 years.

Y = Compound interest 5% over the initial amount for 12 years.

Solution:

Let's calculate the profit for choice 1 = X

Simple interest = 5%

Initial amount = $3500

Time period = 12 years

Formula = A = P (1 + rt)

where, A = Final amount after 12 years

t = time period in years  = 12

P = initial amount to be deposited = $3500

r = annual interest rate = 5%

Plug in the values to get the total amount.

A = 3500(1+0.05x12)

A = $5600 = final amount Lorena will get after 12 years.

Let's calculate the profit for choice 2 = Y

Compound interest = 5%

Initial amount = $3500

Time period = 12 years

Formula = A = P \((\frac{r}{n} + 1)^{nt}\)

where,

A = Final amount after 12 years

t = time period in years  = 12

P = initial amount to be deposited = $3500

r = annual interest rate = 5%

n = number of times interest rate is applied or compounded. = 12

Plug in the values to get the total amount.

A = P \((\frac{r}{n} + 1)^{nt}\)

A = $6285.50

Hence, Lorena should choose choice 2, as it gives more profit over than choice 1.

The forecast for the number of accidents that will occur in the month of May is 110.

To find the trend equation for forecasting using the least-squares regression method, we need to perform a linear regression analysis on the given data.

Let's assign the variable x to represent the month number (1 for Jan, 2 for Feb, etc.) and y to represent the number of accidents.

Using the given data:

x: 1, 2, 3, 4

y: 30, 40, 60, 95

Step 1: Calculate the means of x (bar) and y (bar):

x(bar) = (1 + 2 + 3 + 4) / 4 = 2.5

y(bar) = (30 + 40 + 60 + 95) / 4 = 56.25

Step 2: Calculate the deviations from the means (dx and dy):

dx = x - x(bar)

= 1 - 2.5, 2 - 2.5, 3 - 2.5, 4 - 2.5

  = -1.5, -0.5, 0.5, 1.5

dy = y - ȳ = 30 - 56.25, 40 - 56.25, 60 - 56.25, 95 - 56.25

  = -26.25, -16.25, 3.75, 38.75

Step 3: Calculate the product of the deviations (dxdy):

dxdy = dx * dy

     = (-1.5) * (-26.25), (-0.5) * (-16.25), 0.5 * 3.75, 1.5 * 38.75

     = 39.375, 8.125, 1.875, 58.125

Step 4: Calculate the squared deviations (dx² and dy²):

dx² = dx * dx

    = (-1.5) * (-1.5), (-0.5) * (-0.5), 0.5 * 0.5, 1.5 * 1.5

    = 2.25, 0.25, 0.25, 2.25

dy² = dy * dy

    = (-26.25) * (-26.25), (-16.25) * (-16.25), 3.75 * 3.75, 38.75 * 38.75

    = 689.0625, 264.0625, 14.0625, 1503.125

Step 5: Calculate the sum of the squared deviations (Σdx² and Σdy²):

Σdx² = 2.25 + 0.25 + 0.25 + 2.25 = 5

Σdy² = 689.0625 + 264.0625 + 14.0625 + 1503.125 = 2470.3125

Step 6: Calculate the sum of the product of the deviations (Σdxdy):

Σdxdy = 39.375 + 8.125 + 1.875 + 58.125 = 107.5

Step 7: Calculate the slope (b):

b = Σdxdy / Σdx² = 107.5 / 5 = 21.5

Step 8: Calculate the y-intercept (a):

a = y(bar) - b * x(bar)

= 56.25 - 21.5 * 2.5

= 56.25 - 53.75

= 2.50

Therefore, the trend equation for forecasting is:

y = 2.50 + 21.50x

To find the forecast for the number of accidents in May (x = 5), substitute x = 5 into the equation:

y = 2.50 + 21.50 * 5

= 2.50 + 107.50

= 110

Answer: (f-g)(2)=14

Step-by-step explanation:

(f – g) (-2) means the same as subtracting f(2) and g(2). Since we are given f(x) and g(x), we can use them to solve. There are two ways to solve. One is to find f(2) and g(2), and then subtract them. Another way is to do (f-g)(x), then plug in x=2. I will show both methods.

Method 1

f(2)=3(2)²+1                                [exponent]

f(2)=3(4)+1                                  [multiply]

f(2)=12+1                                     [add]

f(2)=13

g(2)=1-(2)                                    [subtract]

g(2)=-1                  

(f-g)(2)=13-(-1)                            [subtract f(2) and g(2)]

(f-g)(2)=14

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

Method 2

(f-g)(x)=3x²+1-(1-x)                     [distribute -1]

(f-g)(x)=3x²+1-1+x                      [combine like terms]

(f-g)(x)=3x²+x

(f-g)(2)=3(2)²+2                         [plug in x=2, exponent]

(f-g)(2)=3(4)+2                           [multiply]

(f-g)(2)=12+2                             [add]

(f-g)(2)=14

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

Now, we know that (f-g)(2)=14. We confirmed this with both methods.

The value of p from the given equation is 4.5.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign \(=\\\).

The given equation is \(0.5p-3.45=-1.2\)

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

The equation can be solved as follows

\(0.5p-3.45=-1.2\)

\(0.5p= -1.2+3.45\)

\(0.5p= 2.25\)

\(p= 2.25\div0.5\)

\(p= 4.5\)

Answer:

300 seconds

Step-by-step explanation:

The first dog run at v₁ = 15 m/sec     the second one run at  v₂ = 12 m/sec

we know that  d = v*t  then  t  =  d/v

Then the first dog will take  300/ 12  =  25 seconds to make a turn

The second will take   300 / 15   =   20 seconds to make a turn

Then the first dog in 12 turns 12*25 will be at the start point, and so will the second one at the turn 15.

To check  first dog    12 *  25 = 300

And the second dog 15 * 20 = 300

That means that time required for the two dogs to be at the start point together is

300 seconds, in that time the first dog finished the 12 turns, and the second had ended the 15.

Another procedure to solve this problem is as follows:

between  12  m/sec and  15 m/sec   the minimum common multiple  is 300 ( 300 is the smaller number that accept 12 and 15 as factors         12*15 = 300) Then when time arrives at 300 seconds the two dogs will be again in the starting point

Answer:

Step-by-step explanation:

You want a formula for the volume of the given figure, which is a hemisphere of radius r atop a cylinder of the same radius and height r.

The volume of a sphere is given by ...

  V = (4/3)πr³

The volume of a cylinder is given by ...

  V =  πr²h

The given figure is composed of half a sphere, and a cylinder. The total volume will be the sum of the volumes of these parts.

  total volume = 1/2(sphere volume) + (cylinder volume)

Using a height of r for the cylinder, we can substitute the above formulas to get ...

  total volume = 1/2(4/3πr³) +(πr²·r)

  total volume = 2/3πr³ + πr³ = (2/3 +1)πr³

  total volume = (5/3)πr³

When the height is 12 inches, the radius is 6 inches, so the volume of the object is ...

  total volume ≈ (5/3)(3.14)(6 in)³ = 1130.4 in³

About 1130.4 cubic inches of glass will be needed for a paperweight that is 12 inches tall.

The probability that a simple random sample of 45 unemployed individuals will provide is 0.7372

Here, μ = 17.5, σ = 0.8944, x1 = 16.5 and x2 = 18.5.

We need to compute P(16.5<= X <= 18.5).

The corresponding z-value is calculated using Central Limit Theorem.

z = (x - μ)/σ

z1 ⇒ (16.5 - 17.5)/0.8944 = -1.12

z2 ⇒ (18.5 - 17.5)/0.8944 = 1.12

Therefore, we get

P(16.5 <= X <= 18.5) = P((18.5 - 17.5)/0.8944) <= z <= (18.5 - 17.5)/0.8944)

⇒ P(-1.12 <= z <= 1.12) = P(z <= 1.12) - P(z <= -1.12)

⇒ 0.8686 - 0.1314 = 0.7372

The principal limit theorem states that if you have a population with imply μ and trendy deviation σ and take sufficiently huge random samples from the populace with alternative, then the distribution of the pattern method may be about usually distributed.

The radius of the wheel on a car is 30 inches. If the wheel is revolving at 401 revolutions per minute, The linear speed of the car is approximately 19.2 miles per hour.

To find the linear speed of the car in miles per hour, we need to calculate the distance traveled in one minute and then convert it to miles per hour. Here's how we can do it step by step:

Calculate the circumference of the wheel:

The circumference of a circle is given by the formula

C = 2πr

where r is the radius of the wheel.

In this case, the radius is 30 inches, so the circumference is

C = 2π(30)

   = 60π inches.

Calculate the distance traveled in one revolution:

Since the circumference represents the distance traveled in one revolution, the distance traveled in inches per revolution is 60π inches.

Calculate the distance traveled in one minute:

Multiply the distance traveled in one revolution by the number of revolutions per minute.

In this case, it is 60π inches/rev * 401 rev/min = 24060π inches/min.

Convert the distance to miles per hour:

There are 12 inches in a foot, 5280 feet in a mile, and 60 minutes in an hour.

Divide the distance traveled in inches per minute by (12 * 5280) to convert it to miles per hour.

The final calculation is (24060π inches/min) / (12 * 5280) = (401π/66) miles/hour.

Approximating π to 3.14, the linear speed of the car is approximately (401 * 3.14 / 66) miles per hour, which is approximately 19.2 miles per hour.

The probability that the length of stay in the ICU is one day or less is approximately 0.0630 to 4 decimal places.

To calculate the probability that the length of stay in the ICU is one day or less, you need to find the cumulative probability up to one day.

Let's assume that the length of stay in the ICU follows a normal distribution with a mean of 4.5 days and a standard deviation of 2.3 days.

Using the formula for standardizing a normal distribution, we get:z = (x - μ) / σwhere x is the length of stay, μ is the mean (4.5), and σ is the standard deviation (2.3).

To find the cumulative probability up to one day, we need to standardize one day as follows:

z = (1 - 4.5) / 2.3 = -1.52

Using a standard normal distribution table or a calculator, we find that the cumulative probability up to z = -1.52 is 0.0630.

Therefore, the probability that the length of stay in the ICU is one day or less is approximately 0.0630 to 4 decimal places.

The equation of the linear function is:

z = 10 + 4x + 6y

To find the equation of the linear function, we need to determine the values of c, m, and n in the function z = c + mx + ny.

Since the graph of the function intersects the xz-plane at z = 4x + 10 and the yz-plane at z = 6y + 10, we can use these equations to find the values of c, m, and n.

When the graph intersects the xz-plane (y = 0), we have:

z = c + mx + n(0) = c + mx

Comparing this with z = 4x + 10, we can equate the coefficients:

c = 10 (the constant term)

m = 4 (the coefficient of x)

When the graph intersects the yz-plane (x = 0), we have:

z = c + m(0) + ny = c + ny

Comparing this with z = 6y + 10, we can equate the coefficients:

c = 10 (the constant term)

n = 6 (the coefficient of y)
