Answer:

Vertical asymptote at x= -6 and 6. The zero is 0

Step-by-step explanation:

20 blue fish and 50 total

9514 1404 393

Answer:

Step-by-step explanation:

1. The vertical asymptotes are where the denominator is zero.

  x² -36 = 0

  (x -6)(x +6) = 0   ⇒   x = 6 or x = -6 . . . vertical asymptotes

The horizontal asymptote is the function value when x is large. Since the numerator is lower degree than the denominator, the ratio becomes near 0 as x gets large. The horizontal asymptote is y = 0.

The function value is zero when the numerator is zero:

  6x = 0   ⇒   x = 0 . . . . the zero of the function

A function graph is attached, with vertical asymptotes and zero shown.

__

2. You can work this problem by considering the ratios.

If 60% of fish are red, then 40% are blue. The difference in numbers is 60% -40% = 20% of the total number of fish. That difference is 10 fish.

The number of blue fish is 40% of the total, which is 2×20% = 2×10 fish.

There are 20 blue fish.

Answer:

The correct answer would be never

Step-by-step explanation:

The systems of linear equations can have:

1. No solution: When the lines have the same slope but different y-intercept. This means that the lines are parallel and never intersect, therefore, the system of equations has no solution.

2. One solution: When the lines have different slopes and intersect at one point in the plane. The point of intersection will be the solution of the system

3. Infinitely many solutions: When the lines have the same slope and the y-intercepts are equal. This means that the equations represents the same line and there are infinite number of solution.

Therefore, based on the explained above, the conclusion is: Systems of equations with different slopes and different y-intercepts never have more than one solution.

Answer:

Speed per second= 7.5 feet per second

Step-by-step explanation:

Giving the following information:

We have a distance (225 feet), and a time (30 seconds). Also, we know that the speed was constant.

All we have to do is divide the distance by the time and determine the speed per second:

Speed per second= distance / time

Speed per second= 225 / 30

Speed per second= 7.5 feet per second

The value of B is 16.

The correct option is B

A basic quadratic equation, or a second-order polynomial equation with a single variable, is represented by the equation x : ax² + bx + c = 0, where a≠0 for the variable x. As it is a second-order polynomial equation, which is ensured by the algebraic fundamental theorem, it must have at least one solution.

The standard equation for a hyperbola centered at the origin is:

(x²)/(a²) - (y²)/(b²) = 1

where "a" and "b" are the lengths of the transverse and conjugate axes, respectively. To find the value of "b" for the given hyperbola equation, we need to first rewrite it in the standard form.

(x²)/(24²) - (y²)/(b²) = 1

Multiplying both sides by (24²)(b²), we get:

b²(x²) - (24²)(y²) = (24²)(b²)

Dividing both sides by (24²), we get:

b²(x²)/(24²) - y² = b²

Comparing this with the standard equation, we can see that a = 24 and b is the square root of the constant term, which is b² = 576. Therefore, b = 24.

However, the given directrix of x = 576/26 is not consistent with the equation of the hyperbola. The directrix for a hyperbola with center at the origin and transverse axis along the x-axis is given by x = a²/b. Using the value of a = 24, we can find the directrix as:

x = (24²)/b

Setting this equal to 576/26, we get:

(24²)/b = 576/26

Solving for b, we get:

b = 16

Therefore, the correct answer is (B) 16.

Answer:

Amount of chemical solution = 18 gallon

Amount of pure water = 22 gallon

Step-by-step explanation:

Assume;

20% of solution = x

So,

Amount of pure water = 40 gallons - x

Amount of pure water = 40 - x

Computation:

20% of x = 9% of 40 gallon

0.2 x = 3.6

x = 3.6 / 0.2

x = 18 gallon

So,

Amount of chemical solution = 18 gallon

Amount of pure water = Total solution - Amount of chemical solution

Amount of pure water = 40 -18

Amount of pure water = 22 gallon

Answer:

Step-by-step explanation:

From the given information:

Let X be the random variable;

The mean survival time is E(X):

E(X) = μ

E(X) = ∝β

E(X) = 5 × 10

E(X) = 50

To find the standard deviation, we must first determine the variance:

[tex]V(X) = \sigma ^2[/tex]

[tex]V(X) = \alpha \beta ^2[/tex]

[tex]V(X) = 5 \times (10)^2[/tex]

[tex]V(X) = 5 \times 100[/tex]

[tex]V(X) = 500[/tex]

The standard deviation is:

[tex]\sigma =\sqrt{V(X)}[/tex]

[tex]\sigma =\sqrt{500}[/tex]

[tex]\sigma =22.361[/tex]

The standard deviation of survival time = 22.361

(c)

P(X>30) = 1 - P(X ≤ 30)

[tex]= 1 - \int \limits ^{30}_{0} \ f(x) \ dx[/tex]

[tex]= 1 - \int \limits ^{30}_{0} \dfrac{1}{\beta^{\alpha} \Gamma \alpha }x^{a-1} e ^{-x/\beta } \ dx[/tex]

[tex]= 1 - \int \limits ^{30}_{0} \dfrac{1}{\beta^{\alpha} \Gamma (5)}x^{5-1} e ^{-x/10 } \ dx --- (1)[/tex]

So, if:

[tex]y = \dfrac{x}{10}[/tex]

[tex]dy = \dfrac{dx}{10}[/tex]

10dy = dx

and limits of y are 0 and 3.

because;

for x = 0

[tex]y = \dfrac{0}{\beta}[/tex]

y = 0

For x = 30

[tex]y = \dfrac{30}{10}[/tex]

y = 10

From (1);

[tex]P(X> 30) = 1 - \int \limits ^{30}_{0} \dfrac{1}{\beta^{\alpha} \Gamma (5)}x^{5-1} e ^{-x/10 } \ dx[/tex]

[tex]P(X> 30) = 1 - \int \limits ^{3}_{0} \dfrac{(10y)^4}{10^{5} \Gamma (5)}e ^{-y } \ dy[/tex]   since y = x/β

[tex]P(X> 30) = 1 - \int \limits ^{3}_{0} \dfrac{10^4 y^4 \ e^{-y} }{10^{4} \Gamma (5)} \ dy[/tex]

[tex]P(X> 30) = 1 - \int \limits ^{3}_{0} \dfrac{y^4 \ e^{-y} }{ \Gamma (5)} \ dy[/tex]

Since;

[tex]F(a, \alpha )= \int \limits ^a_0 \dfrac{y^{a-1}e^{-y}}{\Gamma (\alpha )} dy[/tex]

Then;

P(X> 30) = 1 - F(3,5)

From the table of incomplete gamma function;

P(X > 30) = 1 - 0.185

P(X > 30) = 0.815

Thus, the probability that an animal survives more than 30 weeks is 0.815

a)The mean survival time of a randomly selected animal of the type used in the experiment is 50.

b)Standard deviation of survival time is 22.36

The standard deviation of a random variable, sample, statistical population, data set, or probability distribution is the square root of its variance.

Suppose x is the random variable.

It is given that α= 5 and β=10.

So, the mean survival E(x)=α β

The mean survival E(x) =5*10

The mean survival E(x) =50

We know that Variance =α β²

So, Variance = 5*10²

Variance =500

We know that standard deviation σ = √Variance

σ = √500

σ = 22.36

Therefore, a)the mean survival time of a randomly selected animal of the type used in the experiment is 50.

b)Standard deviation of survival time is 22.36

Answer:

Smaller number = 4

Larger number = 13

Step-by-step explanation:

Smaller number = x

Larger number = 4x - 3

Sum of the numbers = 17

x + 4x -3 =  17   {Combine like terms}

   5x - 3 = 17    {add 3 to boht sides}

        5x = 17 + 3

        5x = 20      {Divide both sides by 5}

          x = 20/5

         x = 4

      Larger number = 4x - 3

                               = 4*4 -3

                                = 16 - 3

                                = 13
