Answer: The cost of a single ticket is £6.30.

Step-by-step explanation: The group bought 4 tickets and got one for free, which means they paid for 3 tickets. If each of them paid £6.30, then the total amount paid is 4 x £6.30 = £25.20.

To find the cost of a single ticket, we can divide the total paid by the number of tickets bought, which is 4:

£25.20 ÷ 4 = £6.30

Therefore, the cost of a single ticket is £6.30.

The exponential function that passes through the points (0,19) and (2,1539) is y = 19(9)ˣ.

We can use the two given points to form a system of two equations in two unknowns (a and b) to find the exponential function in the form y = abˣ that passes through those points.

Using the point (0,19), we get

19 = ab⁰

19 = a

Using the point (2,1539), we get

1539 = ab²

Substituting a = 19 from the first equation, we get

1539 = 19b²

Solving for b, we get

b² = 81

b = 9 or b = -9

Since we are dealing with an exponential function that models a growth, we will choose the positive value for b. Thus, b = 9.

Now that we know a and b, we can write the exponential function in the form y = abˣ

y = 19(9)ˣ

Therefore, the exponential function is y = 19(9)ˣ

Ceci should give Fluffles 26 grams of food each day after the 15% reduction.

Given that the original amount of food: 30 grams/day

Now, calculate the 15% reduction:

30 grams/day x 0.15 = 4.5 grams/day

Subtract the reduction from the original amount:

30 grams/day - 4.5 grams/day = 25.5 grams/day

Round the answer to the nearest gram:

25.5 grams/day ≈ 26 grams/day

Answer:

76

Step-by-step explanation:

the second number = the first one + 3

the third number = the second one + 5

the fourth number = the third one + 7

the fifth number = the fourth one + 9

because of this, we can know that we add an odd number to the left number

so

sixth = 20+11=31

seventh = 31+13=44

eighth = 44+15=59

ninth = 59+17=76

The range of the cosine function is [-1, 1], there are no real solutions for θ in the given range.

We have,

We can solve the given quadratic equation for cos(θ) using the quadratic formula:

cos(θ) = (-b ± sqrt(b^2 - 4ac)) / 2a

Here, a = 1, b = 7, and c = 4.

Substituting these values, we get:

cos(θ) = (-7 ± √(7² - 4(1)(4))) / 2(1)

cos(θ) = (-7 ± √(41)) / 2

Since 0 ≤ θ < 2π, we need to consider only the solutions that lie in this range.

Using a calculator, we get:

cos(θ) ≈ -3.03 or -0.65

Since the range of the cosine function is [-1, 1], there are no real solutions for θ in the given range.

Answer:

[tex](x-7)^2+(y+2)^2=49[/tex]

Step-by-step explanation:

A tangent of a circle is a straight line that touches the circle at only one point.

Since the circle is tangent to the horizontal line y = 5, the distance between the center of the circle and the line y = 5 is equal to the radius of the circle.

Given the center of the circle is C(7, -2), the y-coordinate of the center is y = -2. Therefore, the radius of the circle is the difference between y = 5 and y = -2:

[tex]\implies r=5-(-2)=7[/tex]

The equation of a circle is:

[tex]\boxed{(x-h)^2+(y-k)^2=r^2}[/tex]

where (h, k) is the center and r is the radius.

Substitute the given center (7, -2) and found radius, r = 7, into the equation of circle:

[tex](x-7)^2+(y-(-2))^2=7^2[/tex]

Simplify:

[tex](x-7)^2+(y+2)^2=49[/tex]

Therefore, the equation of the circle that has center C(7, -2) and is tangent to the line y = 5 is:

[tex]\boxed{(x-7)^2+(y+2)^2=49}[/tex]

The nth term of the sequence 4/5, 1/5, 1/20. 1/80..... is an = 4/5(1/4)^(n - 1)

The definition of the function is given as

The expected value of a $2 ticket is $0.63

To calculate the expected value of a $2 ticket, we need to multiply the probability of winning by the value of the prize, then sum those products:

The Probability of winning the grand prize = 1/2000

Product: (1/2000) x $500 = $0.25

The Probability of winning a secondary prize: 3/2000

Product: (3/2000) x $200 = $0.30

The Probability of winning a third level prize: 8/2000

Product: (8/2000) x $20 = $0.08

The sum of the products:

$0.25 + $0.30 + $0.08 = $0.63

So the expected value of a $2 ticket is $0.63, meaning that on average, a person can expect to win $0.63 for every $2 they spend on a ticket.

The charity is expected to make a profit, which is why the answer is negative.

That is -$2 + $0.63 = -$1.37

Here we can see that the zeros are:

x = -2

x = 1

Then we can write it as:

y = a*(x + 2)*(x - 1)

a) Point estimate = 10/19 = 0.526

b) The sample should be randomly selected from the population.

The sample size should be large enough such that both np and n(1-p) are greater than or equal to 10, where n is the sample size and p is the proportion of students who have a job in the population.

The sampling distribution of the sample proportion should be approximately normal.

c) confidence interval = (0.259, 0.793)

d) confidence interval = (0.176, 0.876)

e) n = 365 students

Given data ,

a)

The point estimate for the proportion of GSU students who have a job is simply the proportion of students in the class who have a job, which is:

point estimate = 10/19 = 0.526 (rounded to three decimal places)

b)

To create a confidence interval for the proportion of GSU students who have a job, the following conditions must be met:

The sample should be randomly selected from the population.

The sample size should be large enough such that both np and n(1-p) are greater than or equal to 10, where n is the sample size and p is the proportion of students who have a job in the population.

The sampling distribution of the sample proportion should be approximately normal.

c)

Assuming the conditions for a confidence interval are met, a 95% confidence interval for the proportion of GSU students who have a job can be calculated as follows:

margin of error = z√(p(1-p)/n)

where z is the z-score corresponding to a 95% confidence level (z = 1.96), p is the point estimate of the population proportion (0.526), and n is the sample size (19).

margin of error = 1.96 √(0.5260.474/19) = 0.267 (rounded to three decimal places)

confidence interval = point estimate ± margin of error = 0.526 ± 0.267

confidence interval = (0.259, 0.793)

Therefore, we can say with 95% confidence that the true proportion of GSU students who have a job is between 0.259 and 0.793.

d)

A 99% confidence interval for the proportion of GSU students who have a job can be calculated using the same formula as above, but with a z-score of 2.576 (corresponding to a 99% confidence level):

margin of error = 2.576sqrt(0.5260.474/19) = 0.350 (rounded to three decimal places)

confidence interval = 0.526 ± 0.350

confidence interval = (0.176, 0.876)

Therefore, we can say with 99% confidence that the true proportion of GSU students who have a job is between 0.176 and 0.876.

e)

To determine the sample size needed to be within 3 percentage points of the true proportion with the point estimate of 0.526, we can use the formula:

n = (z² * p * (1-p)) / E²

where z is the z-score corresponding to the desired confidence level (z = 1.96 for a 95% confidence level), p is the point estimate of the population proportion (0.526), and E is the desired margin of error (0.03).

n = (1.96^2 * 0.526 * 0.474) / 0.03^2

n = 364.16

Hence , we would need a sample size of at least 365 students to be within 3 percentage points of the true proportion using the point estimate from the class data.

Answer: x + 10` is **not** a factor of `f(x) = 5x^3 + 60x^2 + 109x + 90`.

Step-by-step explanation: To determine if `x + 10` is a factor of `f(x) = 5x^3 + 60x^2 + 109x + 90`, we can use the Factor Theorem. The Factor Theorem states that if `f(a) = 0`, then `x - a` is a factor of `f(x)`.

In this case, we want to determine if `x + 10` is a factor of `f(x)`, so we can let `a = -10` and evaluate `f(-10)`:

`f(-10) = 5(-10)^3 + 60(-10)^2 + 109(-10) + 90`

`= -5000 + 6000 - 1090 + 90`

`= -1000`

Since `f(-10) ≠ 0`, we can conclude that `x + 10` is **not** a factor of `f(x) = 5x^3 + 60x^2 + 109x + 90`.

Angle B, in the triangle ABC is solved to be 116 degrees

Angle B is solved using the concept of triangles and exterior angle relationship. This helps to know that addition of exterior angle to ∠B to angle B results to 180 degrees. Hence we have that:

∠B = (15x − 19)°

exterior angle to ∠B is (9x − 17)°

plugging in gives
