The 8th term of the sequence is 4374. A geometric sequence is a sequence in which each term after the first is obtained by multiplying the previous term by a fixed, non-zero number called the common ratio.

To find the 8th term of the geometric sequence, we can use the formula for the nth term of a geometric sequence:

an = a1 x r^(n-1)

where an is the nth term, a1 is the first term, r is the common ratio, and n is the term number.

Given that the first term is 2 and the common ratio is 3, we have:

a1 = 2
r = 3

Plugging in n = 8, we get:

a8 = 2 x 3^(8-1)
a8 = 2 x 3^7
a8 = 2 x 2187
a8 = 4374


In summary, a geometric sequence is a sequence in which each term is obtained by multiplying the previous term by a constant called the common ratio. In this case, the first term is 2 and the common ratio is 3. We can use the formula an = a1 x r^(n-1) to find the nth term of the sequence. By plugging in n = 8, we get the 8th term of the sequence as 4374.

The probability that a randomly selected jury of 12 people is all male is 2.1 × 10⁻⁵.

What is the probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a proposition is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

An order does not matter so it is a Combination.

There are 1,757,440 feet in 333 miles based on the given double number line.

To determine how many feet are in 333 miles based on the given double number line, we need to find the corresponding point on the "Feet" line that corresponds to 333 miles on the "Miles" line.

From the information provided, we can see that the tick marks on the "Miles" line are evenly spaced. Since there are two tick marks between 0 and 2 miles, each tick mark represents a distance of 2/2 = 1 mile.

Similarly, on the "Feet" line, there are two tick marks between 0 and 10,560 feet. Therefore, each tick mark represents a distance of 10,560/2 = 5,280 feet.

To find the number of feet in 333 miles, we can use the ratio between miles and feet. Since each tick mark on the "Miles" line represents 1 mile and each tick mark on the "Feet" line represents 5,280 feet, we can set up a proportion:

1 mile / 5,280 feet = 333 miles / x feet

Simplifying the proportion, we get:

1/5280 = 333/x

Cross-multiplying, we have:

x = 333 * 5280

Calculating the product, we find:

x = 1,757,440 feet

Therefore, there are 1,757,440 feet in 333 miles based on the given double number line.

The area of the cross-section is 16 sq. cm. Thus, option C is the correct answer.

Vertices sides =  2, 3, 6, and 7

Divide part face = parallel to the face of vertices

It is given that a square face is present in the middle of the cube. The area of the cross-section of the cube results from the plane and cube intersection.

To find the distance between the square face of the cube and the length of the side:

distance = \(\sqrt{[(x^{2} - x1)^2 + (y^{2} - y1)^2 + (z^{2} - z1)^2]}\)

we can use the coordinates of any two adjacent sides to find the distance.

distance = \(\sqrt{[(3-2)^2 + (3-2)^2 + (3-1)^2] }\)

distance = \(\sqrt{11}\)

To calculate the area of the face of the cube:

area = \(side^{2}\)

area = \(\sqrt{(11)^2}\)

area = 11

The area of the cross-section can be estimated as:

area = (1/2) x 11 x 4) + 5 vertices of plane

area = 16 sq. cm

Therefore we can infer that the area of the cross-section is 16 sq. cm

Scale factor 1.25 is an expansion since we 'enlarge' the original size 1.25 times

Scale factor 3 is an expansion since we 'enlarge' the original size by 3 times

Scale factor -2 is also an expansion since we 'enlarge' the original size by 2 times but on the opposite direction of the centre of enlargement

Scale factor 3/4 is a contraction since we make the original size 'smaller' by 0.75 times

Scale factor 1/5 is also a contraction since we make the original size 'smaller' by 0.20 times

Literally, contraction means to reduce; while expansion means to increase.

The following absolute value inequalities are used to determine if a scale factor (k) is an expansion or a contraction.

So, we have:

The absolute value of 1.25, -2 and 3 are greater than 1. i.e.

\(|1.25| > 1\)

Remove absolute brackets

\(1.25 > 1\)

\(|-2| > 1\)

Remove absolute brackets

\(2 > 1\)

\(|3| > 1\)

Remove absolute brackets

\(3 > 1\)

Hence, 1.25, -2 and 3 are all expansion scale ratios

The absolute value of 3/4 and 1/5 are between 0 and 1. i.e.

\(0 > |3/4| > 1\)

\(0 > |0.75 | > 1\)

Remove absolute brackets

\(0 > 0.75 > 1\)

\(0 > |1/5| > 1\)

\(0 > |0.2| > 1\)

Answer:

See the attached worksheet.

Step-by-step explanation:

The approach is to use the staffing ratios to calculate the numbher of staff required for each activity.  Some of the results are fractions, so they are rounded up to the nearest whole number.  The attached worksheet shows the distribution of the 17 staff among the activities.

Reducing the staff levels is best achioeved by moving children out of a class having the lowest Child/Staff ratio into one having the highest.  Those two activities are Horse Riding (at 4:1 Kids/Staff) and Canoeing (at 10:1 Kids/Staff).  If we move 6 kids for riding to canoing, the staff level requirement drops to 15, as noted.  There are challeneges with rounding in this calculation, so one might debate the actual staffing needs.

Step-by-step explanation:

u1 = (0, 2, -1/2) and u2 = (2, -2, 1)

The set p = {x1, x2, x3 : 2x1 −x2 + 4x3 = 0} is a plane in R3. To find two vectors u1 and u2 in R3 so that the span of these two vectors is p,

it is important to first determine the equation of the plane in standard form. By solving the equation, we can get x1 = 0, x2 = 2 and x3 = -1/2.

This can be written in vector form as u1 = (0, 2, -1/2).

Now, since the span of two vectors must include all points in the plane, we will choose a second vector which is perpendicular to the first.

A vector perpendicular to u1 is u2 = (2, -2, 1).

Therefore, the span of u1 = (0, 2, -1/2) and u2 = (2, -2, 1) is p, since any point in p can be written as a linear combination of u1 and u2.

The value of the given triple definite integral \($$\int_0^1 \int_0^1 \int_0^{\sqrt{1-x^2}} z^{2021}\left(x^2+y^2\right)^{2022} d y d x d z$$\), is approximately 2.474 × \(10^{-7}\).

The given integral involves three nested integrals over the variables z, y, and x.

The integrand is a function of z, x, and y, and we are integrating over specific ranges for each variable.

Let's evaluate the integral step by step.

First, we integrate with respect to y from 0 to √(1-x^2):

∫_0^1 ∫_0^1 ∫_0^√(1-x^2) z^2021(x^2+y^2)^2022 dy dx dz

Integrating the innermost integral, we get:

∫_0^1 ∫_0^1 [(z^2021/(2022))(x^2+y^2)^2022]_0^√(1-x^2) dx dz

Simplifying the innermost integral, we have:

∫_0^1 ∫_0^1 (z^2021/(2022))(1-x^2)^2022 dx dz

Now, we integrate with respect to x from 0 to 1:

∫_0^1 [(z^2021/(2022))(1-x^2)^2022]_0^1 dz

Simplifying further, we have:

∫_0^1 (z^2021/(2022)) dz

Integrating with respect to z, we get:

[(z^2022/(2022^2))]_0^1

Plugging in the limits of integration, we have:

(1^2022/(2022^2)) - (0^2022/(2022^2))

Simplifying, we obtain:

1/(2022^2)

Therefore, the value of the given integral is 1/(2022^2), which is approximately 2.474 × \(10^{-7}\).

Answer:

See below (I hope this helps!)

Step-by-step explanation:

Because odd numbers are always 1 greater than even numbers, we can call the two odd numbers x + 1 and y + 1 where x and y are even integers. Multiplying the two gives us:

(x + 1) * (y + 1)

= x * y + x * 1 + 1 * y + 1 * 1

= xy + x + y + 1

We know that x * y will be even because x and y are also even and the sum of two even numbers will be even, and we also know that x and y are even and that 1 is odd. Since the sum of even and odd numbers is always odd, the product of any two numbers is always odd.

*NOTE: I put a limitation on x and y in my proof (the limitation was that x and y must be EVEN integers) but you don't have to do that, you could make the odd integers 2x + 1 and 2y + 1 where x and y could be any integer from the set Z like mirai123 did. I simply gave this proof because it was the first thing that came to mind. While mirai123's proof and mine are different, they are still both correct.

Answer:

Prove that the product of any two odd numbers is always odd.

Examples:

\(3 \cdot 7 = 21 \text{ } \boxed{\text{odd}}\\5 \cdot 9 = 45 \text{ } \boxed{\text{odd}}\\83 \cdot 3 = 249 \text{ } \boxed{\text{odd}}\)

Defining an odd number as:

\(u= 2k+1, k \in \mathbb{Z}\)

\(u \cdot u = (2k+1)(2k+1)= 4k^2+4k+1\)

\(\text{Is } \boxed{4k^2+4k+1} \text{ odd?}\)

Yes, it is, because \(4k^2 \text{ and } 4k \text{ will always be even considering } k \in \mathbb{Z}\)

An even number plus one is an odd number.

Let's say event A is the selection of four positive numbers, event B the selection of four negative numbers, and event C the selection of two positive and two negative numbers.

Since four numbers are chosen without replacement,  n(A) = 6 × 5 × 4 × 3 = 360  n(B) = 8 × 7 × 6 × 5 = 1680. In event C, four numbers are to be chosen without replacement such that two numbers are positive and two numbers are negative.

This can be done in following ways:  + + – – OR + – + – OR + – – + OR – + – + OR – – + + OR – + + –  ∴ n(C) = 6 × 5 × 8 × 7 + 6 × 8 × 5 × 7 + 6 × 8 × 7 × 5 + 8 × 6 × 7 × 5 + 6 × 5 × 8 × 7 + 8 × 6 × 5 × 7  = 6 × (8 × 7 × 6 × 5)  =10080  Here, total number of numbers = 14  ∴ n(S) = 14 × 13 × 12 × 11 = 24024

Since A, B, C are mutually exclusive events,

Required probability = P(A) + P(B) + P(C)

= n(A)/n(S) + n(B)/n(S)+ n(C)/n(S)

a) Assuming the numbers must be distinct, there are 36 choices for the first number, 35 choices for the second number, and 34 choices for the third number. Therefore, there are 36 x 35 x 34 = 42,840 possible lock combinations.
b) Assuming the numbers may be the same, there are still 36 choices for each number, so the number of possible lock combinations remains the same, which is 36 x 36 x 36 = 46,656.

a) When the numbers must be distinct, we can choose any number between 0 and 35 for the first number. Once the first number is chosen, we have 35 remaining inging choices for the second number, since it cannot be the same as the first number. Similarly, we have 34 choices for the third number, as it cannot be the same as the first or second number. Therefore, the total number of possible lock combinations is given by the product of the choices for each number: 36 x 35 x 34 = 42,840.
b) When the numbers may be the same, we still have 36 choices for each number, including the possibility of choosing the same number multiple times. Therefore, the number of possible lock combinations remains the same as in case a), which is 36 x 36 x 36 = 46,656.

The 95% upper bound represents the value below which 95% of the data falls. In this case, we have X ~ N(70,38), which means that X follows a normal distribution with a mean of 70 and a standard deviation of 38.

To find the 95% upper bound, we need to find the z-score associated with the 95th percentile.

The z-score can be calculated using the formula:
z = (x - μ) / σ

Where:
x is the value we want to find the z-score for,
μ is the mean of the distribution, and
σ is the standard deviation of the distribution.

In this case, we want to find the z-score corresponding to the 95th percentile, which is 1.645. However, the critical value given is 1.69, which is slightly higher than 1.645. Therefore, we will use the critical value of 1.69 instead.

Now, we can rearrange the formula to solve for x:
x = z * σ + μ

Plugging in the values, we have:
x = 1.69 * 38 + 70

Calculating this, we find that the 95% upper bound is approximately 135.1.
Therefore, we can say with 95% confidence that X will be less than approximately 135.1.
