Answer:

5

Step-by-step explanation:

There are 5 pants 2 shirts and 4 sweaters which makes 6 together, paired up makes 5 outfits and one extra sweater or shirt.

Let a and b be two independent events, if p (a) = 0. 4 and p (a ∪ b) = 0. 64 then the value of the p(b) = 0.4

In this question, we will utilise the notion of independent events and the probability addition rule to determine the probability of event B. The product of the individual probabilities will represent the intersection of independent events.

p(a) = 0.4

p(a∪b) = 0.64

p (a ∩ b) = p(a) x p(b)

p (a ∪ b) = p(a) + p(b) - p(a) x p(b)

0.64 = 0.4 + p(b) - 0.4 x p(b)

p(b) = 0.4

Therefore, the value of the p(b) = 0.4

Independent occurrences are ones whose occurrence is unrelated to any other event. For example, suppose we flip a coin in the air and receive the result Head, then we flip the coin again and obtain the result Tail. The occurrences occur independently of one another in both circumstances. It is one of the several kinds of occurrences in probability.

Let us now look at the whole description of independent events, including a Venn diagram, examples, and how they vary from mutually exclusive events.

The probability that 11 or more of these consumers have called an 800 or 900 telephone number for information about some product is approximately 0.326.

The number of successes in a certain number of independent trials that all have the same probability of success are described by the discrete probability distribution known as the binomial probability distribution. The probability of success is constant during all trials, and it is used in statistics to describe situations where there are two alternative outcomes (success or failure).

The binomial probability distribution is given as:

P(X ≥ k) = 1 - P(X < k)

Here, p = 0.60, and the sample size is n = 20.

Thus,

P(X ≥ 11) = 1 - P(X < 11)

= 1 - ∑(20 choose x) (0.6)ˣ (0.4)⁽²⁰⁻ˣ⁾ for x from 0 to 10

P(X ≥ 11) = 0.326

Hence, the probability that 11 or more of these consumers have called an 800 or 900 telephone number for information about some product is approximately 0.326.

Approximately 16\; {\rm m}16m .

Explanation:

When acceleration is constant, the SUVAT equations would apply. Let aa denote acceleration, uu denote initial velocity, vv denote velocity after acceleration, xx denote displacement, and tt denote the duration of acceleration.

Right before braking, the vehicle (initial velocity: u = 0\; {\rm m\cdot s^{-1}}u=0m⋅s

for t = 4.0\; {\rm s}t=4.0s . Apply the equation v = u + a\, tv=u+at to find the velocity of the vehicle after this period of acceleration:

\begin{gathered}\begin{aligned} v &= u + a\, t \\ &= (0\; {\rm m\cdot s^{-1}}) + (1.3\; {\rm m\cdot s^{-2}})\, (4.0\; {\rm s}) \\ &= 5.2\; {\rm m\cdot s^{-1}}\end{aligned}\end{gathered}

.

It is given that acceleration is constant (at a = (-1.8\; {\rm m\cdot s^{-2}})a=(−1.8m⋅s

) ) during braking. The velocity before this period of acceleration (initial velocity) would now be u = 5.2\; {\rm m\cdot s^{-1}}u=5.2m⋅s

. After t = 1.50\; {\rm s}t=1.50s of braking, the velocity of this vehicle would be:

\begin{gathered}\begin{aligned} v &= u + a\, t \\ &= (5.2\; {\rm m\cdot s^{-1}}) + (-1.8\; {\rm m\cdot s^{-2}})\, (1.50\; {\rm s}) \\ &= 2.5\; {\rm m\cdot s^{-1}}\end{aligned}\end{gathered}

The statement is True. Mean normalization scales data to have a mean of 0, which allows the gradient descent algorithm to more quickly identify the optimum point.

Mean normalization is a feature scaling technique used to speed up the learning process of gradient descent algorithms. It works by mapping the values of a dataset to a range of [-1, 1], or [0, 1], by subtracting the mean from each data point and dividing by the standard deviation. This scaling process helps to reduce the impact of the outliers and normalize the data, allowing the gradient descent algorithm to more quickly converge on the optimal solution. This results in faster and more accurate models.

The relationship between cosine and sine of complementary angles allows us to complete the given equation. Using the cofunction identity, we know that the cosine of an angle is equal to the sine of its complementary angle.

If cos(pi/3) = sin(), we can determine the value of the complementary angle to pi/3 by finding the sine of that angle. To find the lengths of the missing sides in a right triangle, we can use the given information about the angle B and side a. Since cos(B) = 4/5, we know that the adjacent side (side b) is 4 units long and the hypotenuse is 5 units long. Using the Pythagorean theorem, we can find the length of the remaining side, which is the opposite side (side a). Given that a = 50, we can solve for the missing side length. In summary, using the cofunction identity, we can determine the value of the complementary angle to pi/3 by finding the sine of that angle.

To calculate the area of the surface that needs to be painted, we need to determine the total surface area of the shed and subtract the area of the door and the bottom of the shed.

1. Surface area of the cube:

A cube has six equal square faces. Each face has an area of (side length)^2. In this case, the side length of the cube is 6 feet, so the area of each square face is (6 feet)^2 = 36 square feet. Since there are six faces, the total surface area of the cube is 6 * 36 square feet = 216 square feet.

2. Surface area of the square pyramid:

A square pyramid has a square base and four triangular faces. The area of the base is (side length)^2, and the area of each triangular face can be calculated using the formula for the area of a triangle: (base * height) / 2.

The side length of the square base is equal to the side length of the cube, which is 6 feet. So, the area of the base is (6 feet)^2 = 36 square feet.

The height of each triangular face is the slant height, which is given as 5 feet.

The area of each triangular face is (base * height) / 2 = (6 feet * 5 feet) / 2 = 15 square feet.

Since there are four triangular faces, the total area of the triangular faces is 4 * 15 square feet = 60 square feet.

Therefore, the total surface area of the square pyramid is 36 square feet (base) + 60 square feet (triangular faces) = 96 square feet.

3. Area of the door:

The area of the door is given as 5 feet (height) * 4 feet (width) = 20 square feet.

4. Area of the bottom of the shed:

The bottom of the shed is a square with side length 6 feet, so its area is (6 feet)^2 = 36 square feet.

Now, let's calculate the area of the surface that needs to be painted:

Total surface area of shed = Surface area of cube + Surface area of square pyramid

                       = 216 square feet + 96 square feet

                       = 312 square feet

Area of surface that needs to be painted = Total surface area - Area of door - Area of bottom of shed

= 312 square feet - 20 square feet - 36 square feet

= 256 square feet

Therefore, the area of the surface that needs to be painted is 256 square feet.

The correct expression for the magnitude of the vector c = a x b is |c| = |a| |b| sin(theta), where theta is the angle between the two vectors.

The vector product of two vectors a and b is defined as c = a x b = |a| |b| sin(theta) n, where n is the unit vector perpendicular to both a and b in the direction given by the right-hand rule. Since c = a x b, the magnitude of c can be expressed as |c| = |a| |b| sin(theta), where theta is the angle between a and b. Therefore, the correct expression for the magnitude of the vector c = a x b is |c| = |a| |b| sin(theta).

The values we need for the Taylor polynomials are:

f(0) = 5 + 7 = 12

f'(0) = 5 - 7 = -2

f''(0) = 5 + 7 = 12

Using these values, we can write the Taylor polynomial of degree one as:

Answer:

The formula for the volume of a cylinder is V = πr²h, where r is the radius and h is the height.

Given the diameter of both the cylinder and the cone is 8 inches, the radius is 8/2 = 4 inches.

The volume of the cylinder is Vcyl = π(4)²(3) = 48π cubic inches.

The formula for the volume of a cone is V = (1/3)πr²h.

The volume of the cone is Vcone = (1/3)π(4)²(18) = 96π/3 = 32π cubic inches.

Therefore, the relationship between the volume of the cylinder and the cone is that the volume of the cone is exactly two-thirds of the volume of the cylinder.

We can see this by dividing the volume of the cylinder by the volume of the cone:

Vcyl/Vcone = (48π) / (32π) = 3/2

So, the volume of the cylinder is 1.5 times greater than the volume of the cone.
