Step-by-step explanation:

Primero, tienes que saber la cauntidad de los litros en un galon.

Hay 3.7854 litres en un galon

ahora, hacemos un ratio

1 galon = 3.7854 litres

? galones = 600,000 litres

Para encontrar la respuesta, divide 600,000 por 3.7854 para obtener la cauntidad de los galones

600,000 ÷ 3.7854 = 158,503.725 galones

158,503. 725 litres fluyen por segundo.

Hay 60 segundos en un minuto asi que, tenemos que multiplica nuestra respuesta por 60 para calcular nuestra respuesta final.

158,503. 725 × 60 = 9,510,223.49 galones!

The probability the card drawn is a face card is 3/13. The probability the card drawn is not a face card is 10/13. The odds in favor of drawing a face card is 3/10. The odds against drawing a face card are 10/3.

There are 52 cards in a standard deck, and 12 of them are face cards (jack, queen, and king). Therefore, the probability of drawing a face card is 12/52, or 3/13.

The probability of not drawing a face card is 1 minus the probability of drawing a face card. Since the probability of drawing a face card is 3/13, the probability of not drawing a face card is 1 - 3/13, which is 10/13.

The odds in favor of drawing a face card are 3:10, or 3/10. The odds against drawing a face card are 10:3, or 10/3.

In summary:

The probability the  card drawn is a face card: 3/13

The probability the card drawn is not a face card: 10/13

Odds in favor of drawing a face card: 3/10

Odds against drawing a face card: 10/3

To find out how much Mark still owes on his debt, we need to calculate the amount of interest that has accrued on the loan over the time that he has been paying it off. The interest on the loan is compounded semi-annually, so the amount of interest that accrues on the loan will be added to the principal every six months. Since Mark has been paying off his debt for 8 years and the interest is compounded semi-annually, he will have made 16 payments of $500.

To calculate the total amount of interest that has accrued on the loan, we need to know the original principal amount of the loan. Since we don't have that information, we won't be able to calculate the exact amount that Mark still owes on his debt. However, we can use the information that we have to make an educated guess.

If Mark has been making payments of $500 every six months for eight years, then he has paid a total of $500 x 16 = $<<50016=8000>>8000 in principal and interest payments. If the interest on the loan is 2% compounded semi-annually, then the total amount of interest that has accrued on the loan over the past eight years is $8000 x 2% = $<<80002*.01=160>>160. This means that the original principal amount of the loan was $8000 - $160 = $<<8000-160=7840>>7840.

Since Mark still has 8 years left to pay off the debt, and he is making payments of $500 every six months, he will need to make a total of 8 years x 2 payments per year = <<82=16>>16 more payments of $500 to pay off the debt. This means that he will have to pay a total of $500 x 16 = $<<50016=8000>>8000 in principal and interest over the next eight years.

Since the total amount of interest that has accrued on the loan over the past eight years was $160, the total amount of interest that will accrue on the loan over the next eight years is also $160. This means that the total amount of interest that Mark will have to pay over the next eight years is $160 x 2 = $<<160*2=320>>320.

Adding the amount of interest that Mark will have to pay over the next eight years to the amount of principal that he will have to pay, we find that the total amount that Mark will owe on the loan over the next eight years is $8000 + $320 = $<<8000+320=8320>>8320.

Therefore, if Mark has been paying off his debt for eight years and still has eight years left to pay, he still owes a total of $8320 on the loan.

The exponential form of the given sequence is - [tex]t_n[/tex] = [tex]t_(n-1)[/tex] + [tex]2^x[/tex] where x is a set of whole numbers and n is a set of natural numbers.

The given sequence is -  4, 5, 7, 11, 19, 35, 67, ...

the first term - [tex]t_1[/tex] is 4

Hence, we can write the sequence as follows-

4 + [tex]2^0[/tex] = 5

5+[tex](2)^1[/tex]=7

7+[tex](2)^2[/tex]=11

11+[tex](2)^3[/tex]=19

The result for all expressions are

a) r(t) = 6.5t radians

b) C(t) = 20cos(6.5*t) feet

c) H(t) = 36 - C(t)

The situation is depicted in the picture attached considering the center of the wheel as the center of the coordinates system.

Since the angular speed is constant, to find an expression for the angle r(t) in radians we just cross-multiply:

6.5 radians __________ 1 minute

r(t) radians ____________  t minutes

and obviously, r(t) = 6.5t radians

The height C(t) above the center after t minutes is given by

C(t) = 20cos(r(t)) ===>  C(t) = 20cos(6.5*t) feet

When C(t) < 0 means that derek wheel is below the center of the wheel.

Since the center of the Ferris wheel is 36 feet above the ground, the height H(t) above the ground after t minutes is given by

H(t) = 36 - C(t)

Step-by-step explanation: Get Good

The volume of the cone is approximately 134 ft cube.

The cone would fit in 4 times in the red beach ball.

The diameter of the red beach ball is 8 inches, then the cone has the same radius and a height of 8 inches .

Therefore, to know the number of times the beach ball will fit into the cone, we have to find the volume of each solid shape.

Therefore,

volume of the beach ball(sphere) = 4πr³

where

r = 8  /2 = 4 inches

volume of the beach ball(sphere) = 4 × π × 4³

volume of the beach ball(sphere) = 256π ft³

Therefore,

volume of the cone = 1 / 3 πr²h

where

volume of the cone = 1 / 3 × π × 4²  × 8

volume of the cone = 128π / 3

volume of the cone = 42.7π

volume of the cone = 134.078

volume of the cone ≈ 134 ft³

Therefore,

volume of beach ball / volume of cone = 256π / 42.7π = 5.99531615925

Therefore, the cone will fit 4 times into the red beach ball.

The derivative of given function is D(yz+e^x)d(1,1,1) = (3*((59)^1/2)*e)/59≈1.06167045295814  

We have to find the directional derivative of the given function  

f(x,y,z) = yz+e^x at (x0,y0,z0)=(1,1,1) in the direction of the vector

d⃗ =(3,−5,5)  

Find the gradient of the function and evaluate it at the given point:  

To find the gradient of a function (which is a vector), differentiate the function with respect to each variable.  

∇f= (∂f/∂x,∂f/∂y,∂f/∂z)  

∂f/∂x = ∂( yz+e^x )/∂x  

The derivative of a sum/difference is the sum/difference of derivatives:  

∂f/∂x = ∂( yz)/∂x +∂(e^x )/∂x since the derivative of y and z with respect of x is zero.  

∂f/∂x = e^x The derivative of exponential is d(e^x)/dx=e^x.  

Similarly  

d(yz+e^x)/dy = z and d(yz+e^x)/dz = y  

∇(yz+e^x)(x0,y0,z0)=(e^x,z,y)  

Finally plug in the point we get the result  

∇(yz+e^x)|(x0,y0,z0)=(1,1,1)=(e,1,1)  

∇(yz+ex)|(x0,y0,z0)=(1,1,1)=(e,1,1)  

Now we Find the length of the vector: |d⃗ |=((3)^2+(−5)^2+(5)^2)^1/2 =(59)^1/2  

To normalize the vector, divide each component by length:  

d = ((3*((59)^1/2))/59 ,(−5*(59)^1/2)/59,(5*(59)^1/2)/59)  

Finally, the directional derivative is the dot product of the gradient and the normalized vector:  

D(yz+e^x)d(1,1,1) = (e,1,1). ((3*((59)^1/2))/59 ,(−5*(59)^1/2)/59,(5*(59)^1/2)/59)  

D(yz+e^x)d(1,1,1) = (3*((59)^1/2)*e)/59≈1.06167045295814

The correct answer is [tex]H_0: p = 0.24 and H_1: p < 0.24[/tex].

In mathematical notation, the null hypothesis can be written as:

H_0: p = 0.24

where p is the proportion of uninsured motorists in Florida.

The alternative hypothesis can be written as:

H_1: p < 0.24

This means that we are testing the hypothesis that the proportion of uninsured motorists has decreased to a level that is less than 24%.

The null hypothesis is the default assumption, and we will only reject it if we have enough evidence to support the alternative hypothesis. In this case, we would need to collect data that suggests that the proportion of uninsured motorists has decreased to a level that is significantly less than 24%.

The correct answer is [tex]H_0: p = 0.24 and H_1: p < 0.24[/tex].

The correct statements are:

a) The independent variable is the number of people.

b) The initial value (initial fee) for the picnic is $40.

d) As the number of people increases, the total cost of the picnic increases.

A general linear equation is given by:

y = a*x + b

Where a is the slope and b is the y-intercept.

If we know that the line passes through two points (x₁, y₁) and (x₂, y₂) then the slope is given by the formula:

m = (y - y')/x - x'

Now let's analyze the table:

The x-values are the ones in the left and the y-values are the ones on the right, now from the table we can use two points, let's use the first two:

(6, 52) and (9, 58).

Then the slope is:

a = (58 - 52)/9 -6 = 2

Then the line is something like:

y = 2*x + b

To find the value of b, we use the point (6, 52). This means that when x = 6, y must be equal to 52.

We will get:

52 = 2*6 + b

52 = 12 + b

52 - 12 = b = 40

Then the linear equation is:

y = 2*x + 40

Now let's see which statements are correct.

a) The independent variable is the number of people.

True, the "x" represents the number of people.

b) The initial value (initial fee) for the picnic is $40.

True, the y-intercept does not depend on the value of x, so we can say that you need to pay that indifferent of the number of people that goes.

c)The rate of change is $8.67 per person.

False, the rate of change is equal to the slope, in this case is $2 per person.

d) As the number of people increases, the total cost of the picnic increases.

True.

e)  If 4 people attended the picnic, the total cost would be $46.

To see if this is true or not, we just need to evaluate the function that we got in x = 4.

y = 2*4 + 40 = 48

So we can see that this is false.

Therefore, the correct statements are A, B, D

The option that represents the arithmetic series is;

Option C: sum from k equals 0 to 4 of negative 12 plus 7 times k

An arithmetic series is defined as an arithmetic sequence, whereby each term of the series is gotten from the previous term by the addition or subtraction of a common term.

The series is given as;

-12 + (-5) + 2 + 9 + 16

By careful observation, we see that each term in the series is gotten from the previous term by the addition of 7.

The series here is therefore an example of arithmetic sequence.

The equation of the series when the first term is -12 can therefore be written as; -12 + 7·k

Where;

-12 is the first term

7 is the common difference

n is the number of terms

k = n - 1

When k = 0, we have;

-12 + 7·k

= -12 + 7 × 0

= -12

When k = 1, we have;

-12 + 7·k

= -12 + 7 × 1

= -5

When k = 2, we have;

-12 + 7·k

= -12 + 7 × 2

= 2

When k = 3, we have;

-12 + 7·k

= -12 + 7 × 3
