Let X be a random variable with probability density function (1) c(1-) for 0

The probability of not selecting a person with blood type B+ is 90/100.

a) To find the probability of selecting a person with blood type A+ or A- (P(A+ or A-)), first count the number of people with each blood type, then divide the sum of those counts by the total number of people (100).

Number of people with blood type A+ = 34
Number of people with blood type A- = 6

P(A+ or A-) = (34 + 6) / 100 = 40/100

So, the probability of selecting a person with blood type A+ or A- is 40/100.

b) To find the probability of not selecting a person with blood type B+ (P(not B+)), first count the number of people without blood type B+ and then divide that count by the total number of people (100).

Number of people with blood type B+ = 10
Number of people without blood type B+ = 100 - 10 = 90

P(not B+) = 90 / 100 = 90/100

So, the probability of not selecting a person with blood type B+ is 90/100.

Vector that is perpendicular to the level curve at the point (a, b) is the opposite of the gradient vector:

-∇f(a, b) = ([tex]-e^a[/tex] + 1, a sin b)

We can use the gradient of f(x, y) at that point.

The gradient of f(x, y) is given by:

∇f(x, y) = ( ∂f/∂x , ∂f/∂y )

So, we have:

∂f/∂x = [tex]e^x[/tex] - 1

∂f/∂y = -x sin y

At the point (a, b), the gradient vector is:

∇f(a, b) = ( [tex]e^a[/tex] - 1 , -a sin b )

The level curve of f(x, y) is the set of points (x, y) where f(x, y) = k for some constant k. In other words, the level curve is the curve where the surface s intersects the plane z = k.

Let (a, b, c) be a point on the surface s that lies on the level curve at the point (a, b). Then, we have:

f(a, b) = c

Differentiating both sides with respect to x and y, we get:

∂f/∂x dx + ∂f/∂y dy = 0

This equation says that the gradient vector of f(x, y) is orthogonal to the tangent vector of the level curve at the point (a, b).

Therefore, the vector that is perpendicular to the level curve at the point (a, b) is the opposite of the gradient vector:

Since the limit of the sequence is 0, we can say that the sequence is bounded between 0 and some positive number (since all terms in the sequence are positive). Therefore, the answer is (A) bounded.

To determine whether the sequence is increasing, decreasing, or not monotonic, we need to look at how the terms in the sequence change as n increases.

We can rewrite the sequence as:

an = 1/(5n + 4)

As n increases, the denominator 5n + 4 also increases, which means that the fraction 1/(5n + 4) decreases. Therefore, the terms in the sequence decrease as n increases.

So the answer is (B) decreasing.

To determine whether the sequence is bounded, we need to consider the limit of the sequence as n approaches infinity.

The arc length by the given data is 4π cm.

We are given that;

AC≅AD,  ∠C =∠D = 30°

Now,

The arc length formula is:

s = rθ

where s is the arc length, r is the radius, and θ is the central angle in radians.

To use this formula, we need to convert the angle of 120° to radians. We can use the fact that 180° = π radians, so:

120° × π/180° = 2π/3 radians

Then we can plug in the values of r = 6 cm and θ = 2π/3 radians into the formula:

s = 6 × 2π/3 s = 4π cm

The Laplace transform of [tex]e^{(-4t)}sin(4t)[/tex] is 4/((s+4)² + 16).

In mathematics, the Laplace transform is an integral transform that converts a function of a real variable to a function of a complex variable s. The transform has many applications in science and engineering because it is a tool for solving differential equations.

To find the Laplace transform, denoted as ℒ{[tex]e^{(-4t)}sin(4t)[/tex]}, we'll use the following formula:

ℒ{[tex]e^{(-at)}f(t)[/tex]} = F(s+a)
where ℒ{f(t)} = F(s) is the Laplace transform of the function f(t), and "a" is the constant term in [tex]e^{(-at)}[/tex].

In this case, f(t) = sin(4t) and a = 4.

First, let's find the Laplace transform of f(t) = sin(4t), which is given by:
F(s) = ℒ{sin(4t)} = 4/(s² + 16)

Now, apply the formula for ℒ{[tex]e^{(-4t)}f(t)[/tex]}:

ℒ{[tex]e^{(-4t)}sin(4t)[/tex]} = F(s+4)

Step-by-step explanation:

since there are 6 sides, you do 18 divide 6 which is 3

Answer:

The length of the hexagon= 3 because perimeter= the distance around that particular polygon and 3 multiplied by the number of sides of the regular polygon which is 6 to get 18 therefore 3 becomes the length of each side of the hexagon

Part A:

The new deck will be a 4:5 scaled version of the original deck. This means that every dimension of the new deck will be 4/5 times the corresponding dimension of the original deck.

The original deck has a base of 15 feet and a height of 9 feet.

The new deck will have a base of (4/5) * 15 = 12 feet and a height of (4/5) * 9 = 7.2 feet.

Therefore, the dimensions of the new deck are 12 feet for the base and 7.2 feet for the height.

Part B:

To find the area of the original deck, we use the formula for the area of a triangle:

Area = (1/2) * base * height = (1/2) * 15 * 9 = 67.5 square feet.

To find the area of the new deck, we use the same formula with the new dimensions:

Area = (1/2) * 12 * 7.2 = 43.2 square feet.

Therefore, the area of the original deck is 67.5 square feet, and the area of the new deck is 43.2 square feet.

Part C:

The ratio of the areas is:

Area of new deck / Area of original deck = 43.2 / 67.5

Simplifying this fraction, we get:

Area of new deck / Area of original deck = 8 / 15

The scale factor is 4/5, which simplifies to 8/10 or 4/5.

Comparing the ratio of the areas to the scale factor, we see that:

Area ratio / Scale factor = (8/15) / (4/5) = (8/15) * (5/4) = 1

Therefore, the ratio of the areas is equal to the scale factor. This makes sense since the area of a triangle is proportional to the square of its dimensions. In this case, the scale factor is applied to both the base and the height, so the area ratio is equal to the scale factor squared, which is 16/25.

Answer:

Step-by-step explanation:

Part A: To find the dimensions of the new deck, we need to scale the base and height of the original deck by a factor of 4:5.

Scaling factor = 4/5

New base = 15 * (4/5) = 12 feet

New height = 9 * (4/5) = 7.2 feet

Therefore, the dimensions of the new deck are 12 feet for the base and 7.2 feet for the height.

Part B: The area of the original deck can be found by using the formula for the area of a triangle:

Area = (1/2) * base * height = (1/2) * 15 * 9 = 67.5 square feet.

The area of the new deck can also be found using the same formula:

Area = (1/2) * base * height = (1/2) * 12 * 7.2 = 43.2 square feet.

Part C: The ratio of the areas of the two decks can be found by dividing the area of the new deck by the area of the original deck:

Ratio of areas = (43.2 / 67.5) ≈ 0.64

The scale factor is 4:5 or 0.8.

Comparing the ratio of areas to the scale factor:

Ratio of areas / scale factor = (0.64 / 0.8) = 0.8

The ratio of the areas divided by the scale factor is equal to 0.8, which makes sense since the scale factor is the factor by which the dimensions were scaled up, and the ratio of areas tells us how much the area was scaled up.

The derivative of y√(1/(t(8t+1))) is (dy/dt √(1/(t(8t+1))) - y * (4t√t+1 + √(8t+1))/(2t√(t(8t+1)))).

To use logarithmic differentiation to find the derivative of y√(1/(t(8t+1))), we can follow these steps:

ln(y√(1/(t(8t+1)))) = ln(y) + 1/2 ln(1/(t(8t+1)))

d/dt ln(y√(1/(t(8t+1)))) = d/dt [ln(y) + 1/2 ln(1/(t(8t+1)))]

d/dt ln(y√(1/(t(8t+1)))) = (dy/dt √(1/(t(8t+1))) - y * (4t√t+1 + √(8t+1))/(2t√(t(8t+1))))

So, the final expression y√(1/(t(8t+1))) is

The values of probability are a. P(X < 71) = 0.90, b. P(X ≤ 24) = 0.73, and c. P(X ≤ 71) = 0.90

We need to calculate the probabilities for a continuous random variable X,

given that P(24 ≤ X ≤ 71) = 0.17 and P(X > 71) = 0.10.

a. P(X < 71)
To find P(X < 71), we can use the fact that P(X < 71) = 1 - P(X ≥ 71).

Since P(X > 71) = 0.10, we know that P(X ≥ 71) = P(X > 71) = 0.10. Thus, P(X < 71) = 1 - 0.10 = 0.90.

b. P(X ≤ 24)
We can use the given information P(24 ≤ X ≤ 71) = 0.17 and P(X < 71) = 0.90 to find P(X ≤ 24).

We know that P(X ≤ 24) = P(X < 71) - P(24 ≤ X ≤ 71) = 0.90 - 0.17 = 0.73.

c. P(X ≤ 71)
To find P(X ≤ 71), we can use the fact that P(X ≤ 71) = P(X < 71) + P(X = 71).

Since X is a continuous random variable, the probability of it taking any specific value, such as 71, is 0.

Therefore, P(X ≤ 71) = P(X < 71) = 0.90.

The linear approximation of f(1.01) is approximately 1.01.

To approximate f(1.01) using a linear approximation, we need to find the equation of the tangent line to the graph of f(x) at x = 1. We can do this by finding the slope of the tangent line and using the point-slope form of a linear equation.

First, we find the derivative of f(x):

f'(x) = e(1-x)

Then, we evaluate f'(1) to find the slope of the tangent line at x = 1:

f'(1) = e(1-1) = e0 = 1

So the slope of the tangent line is 1.

Next, we find the value of f(1):

f(1) = 2 - e(1-1) = 2 - e0 = 2 - 1 = 1

So the point on the graph of f(x) that corresponds to x = 1 is (1, 1).

Using the point-slope form of a linear equation, we can write the equation of the tangent line as:

The area of the backyard is ...

  A = LW = (6 yd)(4 yd) = 24 yd²

The area of the patio is ...

  A = LW = (3 yd)(2 yd) = 6 yd²

Garden area

The garden area is the area of the backyard that is not taken up by the patio:

  24 yd² -6 yd² = 18 yd²

The garden covers 18 square yards.

10 cartons of eggs will contain 8 more broken eggs than 4 cartons if a grocery store worker is checking for broken egg cartons. Each carton of eggs contains 12 eggs. He checks 4 cartons and finds 8 broken eggs.

Assuming that the proportion of broken eggs in the sampled cartons is representative of the entire batch of cartons, the worker can use this information to predict the number of broken eggs in the rest of the cartons.

The worker checked 4 cartons of eggs, each with 12 eggs, for a total of 4 x 12 = 48 eggs. Out of these 48 eggs, 8 were found to be broken.

To estimate the number of broken eggs in the rest of the cartons, the worker can use proportionality. The proportion of broken eggs in the sample is 8/48 = 1/6. Therefore, the worker can predict that out of the marginal cost remaining cartons of eggs, 1/6 of the eggs will be broken.

The closest option is C, which predicts that there will be 16 broken eggs in 10 cartons, which is 8 more broken eggs than in the 4 cartons the worker checked. This implies an average of 2 broken eggs per carton, which is consistent with the prediction of 2x broken eggs in the remaining cartons. Therefore, option C is the best answer.

where x is the score we're interested in, μ is the mean, and σ is the standard deviation (which is the square root of the variance). Plugging in the values we have:

z = (16.5 - 24) / √9
z = -7.5 / 3
z = -2.5

Therefore, the z-value for a score of 16.5 in this normal distribution is -2.5.

To find the z-value for a score of 16.5 in a normal distribution with a mean (µ) of 24 and a variance of 9, you'll need to use the z-score formula:

z = (X - µ) / σ

Where X is the given score (16.5), µ is the mean (24), and σ is the standard deviation. Since the variance is 9, the standard deviation (σ) is the square root of 9, which is 3. Plug these values into the formula:

z = (16.5 - 24) / 3
z = -7.5 / 3
z = -2.5

The median of complaints received per week is 2.

To find the median of complaints received per week, we need to arrange the probabilities in ascending order and then find the probability at the middle position.

Arranging the probabilities in ascending order, we get:

Number of complaints 0 1 2 3 4 5
Probability 0.05 0.07 0.09 0.18 0.26 0.35

The median position is (n+1)/2, where n is the total number of probabilities. In this case, n=6, so the median position is (6+1)/2=3.5.

The probability at position 3 is 0.09 and the probability at position 4 is 0.18. Therefore, the median probability is the average of these two probabilities, which is (0.09+0.18)/2=0.135.

To find the median number of complaints, we need to find the number of complaints that corresponds to the median probability. Starting from the first probability, we add up the probabilities until we reach a total of at least 0.135.

0.05 + 0.07 + 0.09 = 0.21

Therefore, the median number of complaints is 2.
So, the answer is 2 (rounded to the nearest integer).

The coordinates of P that partitions AB in the ratio 2 to 3 include the following: [3, 4].

In this scenario, line ratio would be used to determine the coordinates of the point P on the directed line segment that partitions the segment into a ratio of 2 to 3.

In Mathematics and Geometry, line ratio can be used to determine the coordinates of P and this is modeled by this mathematical equation:

P(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

By substituting the given parameters into the formula for line ratio, we have;

P(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

P(x, y) = [(2(6) + 3(1))/(2 + 3)],  [(2(7) + 3(2))/(2 + 3)]

P(x, y) = [(12 + 3)/(5)],  [(14 + 6)/5]

P(x, y) = [15/5],  [(20)/(5)]

P(x, y) = [3, 4]
