Santa Claus has 3h+11 red presents and h+5 white presents in his stocking. Ethan selects a present at random from the stocking.
The value of h is 1.89. The solution involves setting up and solving an equation involving the probabilities of selecting a red or white present.
Santa Claus has a total of 3h+11 red presents and h+5 white presents in his stocking. If Ethan selects a present at random from the stocking, the probability of obtaining a red present is given as 19/26. Using this information, we can form an equation (3h+11)/(4h+16) = 19/26 and solve for h. Cross-multiplying and simplifying, we get 494h = 936, which leads to h = 1.89. Therefore, the value of h that satisfies the given conditions is approximately 1.89.

2 Let y = 3x 2 − 4x + 2. Write y in the form a(x + b) 2 + c
The required form of a(x + b)² + c to rewrite the given expression y = 3x² − 4x + 2 is given by y = 3(x - (2/3))² + 4/3.
Expression is equal to,
y = 3x² − 4x + 2
Required form to express 'y' is equal to,
a(x + b)² + c
Complete the square by adding and subtracting the square of half the coefficient of the x-term we get,
y = 3x² - 4x + 2
⇒ y = 3(x² - (4/3)x) + 2
⇒ y = 3(x² - 2(2/3)x) + 2
⇒ y = 3(x² - (4/3)x + (2/3)² - (2/3)²) + 2
⇒ y = 3(x - (2/3))² - 3(2/3)² + 2
Simplify the constant terms we have,
⇒ y = 3(x - (2/3))² - 2/3 + 2
⇒ y = 3(x - (2/3))² + 4/3
Therefore, the expression y = 3x² − 4x + 2 written in the form a(x + b)² + c is equal to y = 3(x - (2/3))² + 4/3.

A trinomial is a polynomial with three terms. Each trinomial can be written in the form ax^2+bx+c, where a, b and c are constants, and x is a variable. If a trinomial has (3x+2) as a factor, then it can be written in the form (3x+2)(ax+b). By multiplying out this expression, we can obtain the trinomial ax^2+bx+c.
To find the trinomials that have (3x+2) as a factor, we need to solve the equation ax^2+bx+c = (3x+2)(ax+b). This can be done by equating coefficients of the same powers of x. For example, equating the coefficients of x^2 gives us the equation a = 3a. Since a cannot equal both 3a and 0, we must have a = 0. Similarly, equating the coefficients of x gives us the equation b = 3b+2a, so b = -2a. Finally, equating the constants gives us the equation c = 3b+2a, so c = 2a.

Many historians agree that there is about 1 chance in 4 that Jones wrote the ‘Q document’ and 3 chances in 4 that Smith wrote it. In a new analysis of the 10,000-word document, the word ‘that’ is found to occur 27 times. From the known writings of Smith and Jones, experts assess a probability of 0. 0084 that this frequency of ‘that’ would be observed if Jones were the author, whilst the probability for Smith would be 0. 4. In the light of this new evidence, what now is the probability that Jones is the author?
The probability of Jones being the author is 0.0275.
The new evidence updates the probability of Jones being the author from 1 in 4 to 0.0084. The probability of Smith being the author is 0.4.
To calculate the new probability, we need to use Bayes' theorem.
P(Jones|that) = P(that|Jones) x P(Jones) / (P(that|Jones) x P(Jones) + P(that|Smith) x P(Smith))
P(Jones|that) = 0.0084 x 0.25 / (0.0084 x 0.25 + 0.4 x 0.75)
P(Jones|that) = 0.0084 / (0.0084 + 0.3)
P(Jones|that) = 0.0084 / 0.3084

What is the perimeter of this figure?
Use 3.14 for π .
Enter your answer as a decimal in the box.
__ cm
the perimeter of the figure is approximately 48.56 cm.
What are the definitions of perimeter and its unit?The perimeter of a shape in geometry refers to its whole boundaries. The lengths of a shape's edges and sides are added to find its perimeter.
from the question:
The lengths of all the figure's sides must be added up in order to determine their perimeter.
The rectangle has two sides that are 10 cm long and two that are 8 cm long, making its perimeter:
P_rect = 2(10 cm) + 2(8 cm) = 36 cm
Since it shares a side with the rectangle, the quarter circle has a radius of 8 cm and an arc length that is one-fourth of the circle's diameter, which is:
L_circle = (1/4)(2πr) = (1/4)(2π)(8 cm) = 4π cm
Therefore, the perimeter of the figure is:
P = P_rect + L_circle = 36 cm + 4π cm ≈ 48.56 cm
The figure's perimeter, when rounded to two decimal places, is roughly 48.56 cm.

Type an exact answer, using radicals and i as needed. Use Use the complex zeros to factor f f(x) = (Type your answer in factored form. Type an exact answer, using radicals and i as
The complex zeros of the given polynomial function f(x) = x^4 + 170x^2 + 169 are [-i\sqrt{2}, i\sqrt{2}, -1, 1].
To find the complex zeros of the given polynomial function f(x) = x^4 + 170x^2 + 169, we can start by noting that this polynomial is a perfect square of a binomial. Specifically, we have:
f(x) = (x^2 + 13)^2
Therefore, the zeros of f(x) are the values of x that satisfy f(x) = 0. In other words, we need to solve the equation:
(x^2 + 13)^2 = 0
Taking the square root of both sides, we get:
x^2 + 13 = 0
Solving for x, we get:
x = ±i√13
However, we need to find the complex zeros of f(x), which are the roots of the equation f(x) = 0. Since f(x) = (x^2 + 13)^2, the zeros of f(x) are exactly the same as the zeros of x^2 + 13, namely ±i√13.
But this is not the end of the story. Since x^2 + 13 has only two distinct roots, namely ±i√13, each of these roots must occur with multiplicity 2 in f(x). This means that f(x) has a repeated root at each of the values ±i√13.
Finally, we note that x^2 + 13 can be factored as:
x^2 + 13 = (x + i√13)(x - i√13)
Therefore, we can write f(x) as:
f(x) = (x^2 + 13)^2 = (x + i√13)^2(x - i√13)^2
This gives us the factored form of f(x), and we can see that it has four roots, namely -i√13, i√13, -i√13, and i√13, which can be simplified to -i√2, i√2, -1, and 1.

Finding the Volume of an Overflow PanThe polynomial function
To find the volume of the pan, we first need to determine the dimensions of the base and height.
If we cut equal squares with sides of length x from the corners of a 30 cm by 20 cm piece of aluminum, then
The base of the pan will have dimensions (30-2x) cm by (20-2x) cm.The height of the pan will be x cm.Thus, the volume of the pan can be expressed as:
V(x) = (30-2x)(20-2x)x
The volume
Using the remainder theorem, we have
V(6) = (30 - 2 * 6)(20 - 2 * 6) * 6

The 95% of the babies born to 22-year-old mothers will weigh between 3308.4 grams and 5665.6 grams.The correct answer is option C) (3051.25, 5408.49).
To get started, let's put the mother's age into the given equation to determine the mean birth weight. Then, we'll use the RMS value to calculate the standard deviation.The equation for predicting baby birth weight in grams given the mother's age is: Y = -1163.45 + 245.15XWhere X is the mother's age, and Y is the baby's birth weight. We are given X=22, so let's use that to find the predicted mean birth weight:Y = -1163.45 + 245.15(22) = 4486.95 gramsThe RMS is given to be 589.3 grams. Because we're told that the distribution is approximately normal, we can use the 68-95-99.7 rule to find the 95% prediction interval. Here are the steps:Subtract the RMS from the mean to find the lower endpoint of the interval:4486.95 - (2 x 589.3) = 3308.35Add the RMS to the mean to find the upper endpoint of the interval:4486.95 + (2 x 589.3) = 5665.55Round both values to four decimal places, as instructed in the problem:3308.35 rounds to 3308.4 grams5665.55 rounds to 5665.6 gramsTherefore, about 95% of the babies born to 22-year-old mothers will weigh between 3308.4 grams and 5665.6 grams.The correct answer is option C) (3051.25, 5408.49).

Answer:
m = - 6.5
Step-by-step explanation:
the remainder theorem states
if a function f(x) is divide by (x - a) then the remainder is equal to f(a)
given
p(x) is divided by (x - 2) then p(2) = 2 ( the remainder )
then
2[tex](2)^{4}[/tex] - 5(2)² + 2m + 3 = 2
2(16) - 5(4) + 2m + 3 = 2
32 - 20 + 2m + 3 = 2
15 + 2m = 2 ( subtract 15 from both sides )
2m = - 13 ( divide both sides by 2 )
m = - 6.5
