If you look at the graph of y = 16x^4 - 81, you see that it intersects the x-axis at two distinct places so there are two real solutions.  Whenever a polynomial function intersects the x-axis, there are at least one or more real roots.

I attached a picture of the graph using Desmos, where you'll see that there are two real roots.

To write the given quadratic equation, y = (x + 1)^2 - 4, in factored form, we can start by expanding the equation using the square of a binomial:

y = (x + 1)(x + 1) - 4

y = (x^2 + 2x + 1) - 4

y = x^2 + 2x + 1 - 4

y = x^2 + 2x - 3

Now, to find the zeros of the equation, we set y = 0 and solve for x:

x^2 + 2x - 3 = 0 To factor this quadratic equation, we need to find two numbers whose product is -3 and whose sum is 2. The numbers that satisfy this condition are 3 and -1:

(x + 3)(x - 1) = 0

Now, setting each factor equal to zero, we can find the values of x:

x + 3 = 0  =>  x = -3

x - 1 = 0  =>  x = 1

Therefore, the factored form of the equation y = (x + 1)^2 - 4 is (x + 3)(x - 1) = 0, and the zeros of the equation are x = -3 and x = 1.

The proportion of male babies less than two months old in the United States that weigh more than 10.1 pounds is 0.7554 or approximately 75.54%.

We are given the following information:

Mean = 11.9 pounds

Standard deviation = 2.6 pounds

To find the proportion of babies that weigh more than 10.1 pounds, we need to find the z-score and then find the corresponding area under the standard normal distribution curve.

1: Calculate the z-scoreWe can calculate the z-score using the formula:

z = (x - μ) / σ

where x is the weight of the baby in pounds, μ is the mean weight of male babies less than two months old in the United States, and σ is the standard deviation of the weights of male babies less than two months old in the United States.

Let's plug in the given values:x = 10.1 pounds

μ = 11.9 pounds

σ = 2.6 pounds

z = (10.1 - 11.9) / 2.6z = -0.6923 (rounded to four decimal places)

2: Find the area under the standard normal distribution curve

We can use a standard normal distribution table or a calculator to find the area under the curve for a z-score of -0.6923. Using a calculator, we get:

P(z > -0.6923) = 0.7554 (rounded to four decimal places)

First, we need to find the number of students who bring lunch:

1/3 x 36 = 12 students bring lunch.

Next, we need to find the number of students who order lunch:

1/2 x 12 = 6 students order lunch.

So, the total number of students who eat lunch each day is:

12 (who bring lunch) + 6 (who order lunch) = 18 students.

Rounding to the nearest whole number, we would expect to wait between 39 and 53 minutes about 29 times out of 29 visits using standard deviation.

We can use the normal distribution to find the probability of waiting between 39 and 53 minutes for each visit, and then multiply that probability by the number of visits to get the expected number of times waiting in that range.

First, we need to standardize the range of waiting times using the formula:

z = (x - mu) / sigma

where x is the waiting time, mu is the mean waiting time, sigma is the standard deviation, and z is the corresponding z-score.

For the lower limit of 39 minutes:

z1 = (39 - 46) / 3 = -2.33

For the upper limit of 53 minutes:

z2 = (53 - 46) / 3 = 2.33

Next, we can use a standard normal distribution table or calculator to find the probability of waiting between -2.33 and 2.33, which is approximately 0.9902.

Therefore, the expected number of times waiting between 39 and 53 minutes out of 29 visits is:

Expected number = 0.9902 * 29 = 28.68

The answer is that there are 32 ways to place two indistinguishable kings on an empty chess board so that they do not attack each other.

To answer this question, we need to understand the basic rules of chess. A king can move one square in any direction, including diagonally. So, to ensure that two kings are not attacking each other, we need to place them on two squares that are not adjacent to each other, and not on the same diagonal line.
There are 64 squares on a chess board, and the first king can be placed on any of those squares. The second king, however, has fewer options because it cannot be placed on the same row, column or diagonal as the first king.
The number of ways to place the second king will depend on where the first king was placed. For example, if the first king was placed in one of the corners, then the second king will have only two possible squares to be placed in. On the other hand, if the first king was placed in the center of the board, then the second king will have fewer options.
Overall, there are 32 possible squares for the second king to be placed in, which means that there are 32 possible ways to place two indistinguishable kings on an empty chess board so that they do not attack each other.
In summary, the answer is that there are 32 ways to place two indistinguishable kings on an empty chess board so that they do not attack each other.

To show that points C(-4, 3), A(6, 1), and T(2, -3) form a right-angled triangle, we can calculate the slopes of the lines connecting these points.

The slope of a line passing through two points (x1, y1) and (x2, y2) is given by:

slope = (y2 - y1) / (x2 - x1)

Let's calculate the slopes of the lines formed by the points:

Slope of line CA:

m_CA = (1 - 3) / (6 - (-4))

= (-2) / 10

= -1/5

Slope of line CT:

m_CT = (-3 - 3) / (2 - (-4))

= (-6) / 6

= -1

Slope of line AT:

m_AT = (-3 - 1) / (2 - 6)

= (-4) / (-4)

= 1

Since two lines are perpendicular if and only if the product of their slopes is -1, we can check if the product of the slopes of CA and AT is -1. If it is, then the triangle formed by the points C, A, and T is a right-angled triangle.

Product of slopes m_CA and m_AT:

(-1/5) * (1) = -1/5

The product of the slopes is -1/5, which is not equal to -1. Therefore, the points C(-4, 3), A(6, 1), and T(2, -3) do not form a right-angled triangle.

Hence, we can conclude that the points C, A, and T do not form a right-angled triangle based on the slopes of the lines connecting them.

A polygon having 5 sides or 5 angles is called a pentagon. The terms "pentagon" and "gonia," which both denote five angles, are the components of the word "pentagon." End to end, the four sides of a hexagon come together to create a shape. The geometric form known as a pentagon has five sides or five angles. In this case, "Penta" stands for five, and "gon" for an angle. One of the several kinds of polygons is the pentagon.

A point has an angle sum of 360 degrees.

The square's internal angles are all 90 degrees.

The regular pentagon has 108 degree internal angles.

Our unidentified polygon's interior angle is 360 - 108 - 90, or 162 degrees.

So the frequency of individuals with red hair in population b after 10 generations of migration is approximately 0.02%.

We need to use the Hardy-Weinberg equation, which describes how the frequencies of alleles in a population will change over time.
The equation is:
p^2 + 2pq + q^2 = 1
Where:
p = frequency of one allele
q = frequency of the other allele
p^2 = frequency of homozygous dominant individuals
2pq = frequency of heterozygous individuals
q^2 = frequency of homozygous recessive individuals
In this case, the recessive trait is red hair, so we'll use q to represent the frequency of the recessive allele.
In population a, q = 0.49, so p (the frequency of the dominant allele) = 1 - q = 0.51.
In population b, q = 0.25, so p = 0.75.
After the emigrants from population a migrate to population b, the new frequency of the recessive allele in population b will be:
q' = (0.1 x 0.49) + (0.9 x 0.25) = 0.286
This is the new value of q after one generation of migration. To calculate the frequency of red-haired individuals after 10 generations, we need to use the equation:
q^10 = (0.286)^10 = 0.0002
So the frequency of individuals with red hair in population b after 10 generations of migration is approximately 0.02%.
The frequency of individuals with red hair in population b after 10 generations of migration is approximately 0.02%. This is based on the assumption that the emigrants from population a mate randomly with members of population b and that the population sizes remain constant over time.

The probability that the sample contains exactly two defective parts from a production process with a 6% defect rate is 0.0299. Option B is answer

To find the probability, we can use the binomial probability formula. The formula is P(X=k) = (n C k) * (p^k) * ((1-p)^(n-k)), where n is the sample size, k is the number of successes (defective parts), p is the probability of success (defect rate), and (n C k) represents the combination formula.

In this case, n = 5 (sample size), k = 2 (number of defective parts), and p = 0.06 (probability of a part being defective). Plugging these values into the formula, we get P(X=2) = (5 C 2) * (0.06^2) * ((1-0.06)^(5-2)) = 10 * 0.0036 * 0.8464 = 0.0299.

The expected gain or loss from playing the game 15 times is -$75.00, indicating an expected loss of $75.00.

To determine the expected gain or loss from playing the game 15 times, we need to calculate the expected value.

The probability of getting three tails (winning) in a single coin toss is (1/2) * (1/2) * (1/2) = 1/8, since each coin toss is independent and has a 1/2 probability of landing tails.

The probability of losing in a single coin toss is 1 - 1/8 = 7/8.

If we play the game 15 times, the expected number of wins is (1/8) * 15 = 15/8, and the expected number of losses is (7/8) * 15 = 105/8.

The amount gained from winning is $10, and the amount lost from losing is $2.

Therefore, the expected gain or loss can be calculated as follows:

Expected gain or loss = (Expected number of wins * Amount gained) - (Expected number of losses * Amount lost)

= (15/8 * $10) - (105/8 * $2)
