The equation system serves as the foundation for this query. As a result, the number of sliders and onion rings in the combination meal could both be calculated using the system of equations 2s = r and r(70) + s(200) = 1020.

Given:

Each onion ring at one eatery contains 70 calories, while each slider has 200 calories. An onion ring and slider combo meal has 1020 calories overall and twice as many sliders as onion rings, according to research.

According to the question:

Let r be the number of onion rings and s be the number of sliders.

Now, it is stated that there are twice as many sliders as onion rings. mathematical form, it is expressed as,

The first system of equations is 2s = r.

Additionally, each onion ring contains 70 calories, and each slider contains 200 calories. A combined lunch of sliders and onion rings has 1020 calories overall. This indicating as

The second set of equations reads as follows: r(70) + s(200) = 1020.

As a result, the number of sliders and onion rings in the combination meal could both be calculated using the system of equations 2s = r and r(70) + s(200) = 1020.

Simplified Version:

r = onion rings amount

s = sliders amount

system of equations

2s = r

r(70) + s(200) = 1020

By using unitary method, we found that the cost of 5m cloth is Rs. 1050.

According to the unitary method, the cost of 1 meter of cloth is equal to the total cost of 7 meters of cloth divided by 7. That is,

Cost of 1m cloth = Total cost of 7m cloth/7

We know that the total cost of 7m cloth is Rs. 1470. Therefore,

Cost of 1m cloth = 1470/7

Cost of 1m cloth = Rs. 210

This means that the cost of 1 meter of cloth is Rs. 210. Now, we need to find the cost of 5m cloth. To do that, we can use the unitary method again.

Cost of 5m cloth = Cost of 1m cloth x 5

Cost of 5m cloth = Rs. 210 x 5

Cost of 5m cloth = Rs. 1050

Therefore, the cost of 5m cloth is Rs. 1050.

She made the 6 into a five to make the 0 a 1 too early, because 24 can go into 60 twice, but in order to subtract the 8, you would then have to make the 6 into a 5 as well as the 0 into a 1.

Step-by-step explanation:

6048 divided by 24 is 252

a) The probability that in a group of 9 couples, at least 6 husbands have a college degree can be calculated using the binomial probability formula.

b) In a group of 24 couples, the expected number of husbands with a college degree is 15.6, and the standard deviation is approximately 2.35.

a) To find the probability that at least 6 husbands have a college degree in a group of 9 couples, we can use the binomial probability formula. Let's denote the probability of a husband having a college degree as p = 0.65 and the number of couples as n = 9.

The probability mass function for the binomial distribution is given by P(X = k) = C(n, k) * p^k * (1 - p)^(n - k), where X is the number of husbands with a college degree and k is the number of husbands with a college degree.

To find the probability of at least 6 husbands having a college degree, we sum the probabilities of having 6, 7, 8, and 9 husbands with a college degree:

P(X ≥ 6) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9)

P(X = k) = C(9, k) * 0.65^k * (1 - 0.65)^(9 - k)

Calculating each term and summing them up will give us the desired probability.

b) To find the expected number of husbands with a college degree in a group of 24 couples, we multiply the probability of a husband having a college degree (p = 0.65) by the number of couples (n = 24):

Expected number = p * n

To find the standard deviation of the number of husbands with a college degree, we use the formula for the standard deviation of a binomial distribution:

Standard deviation = sqrt(n * p * (1 - p))

Plug in the values of n and p to calculate the standard deviation.

Please note that in both parts, we assume that each couple is independent, and the probability of a husband having a college degree is constant across all couples.

a) The solution to the recurrence relation is an = [(1 + √2)/4](2 + 2√2)^n + [(1 - √2)/4](2 - 2√2)^n.  (b) The solution to the recurrence relation is an = -2·2^n + 3·2^n = 2^n(3 - 2^n).

(a) The characteristic equation of the recurrence relationan = 4an−1 + 4an−2 is r^2 - 4r - 4 = 0. Solving this quadratic equation, we get r = 2 ± 2√2. Therefore, the general solution of the recurrence relation is an = c1(2 + 2√2)^n + c2(2 - 2√2)^n. Using the initial conditions a0 = 1 and a1 = 2, we can solve for the constants c1 and c2. We get c1 = (1 + √2)/4 and c2 = (1 - √2)/4. Therefore, the solution to the recurrence relation is an = [(1 + √2)/4](2 + 2√2)^n + [(1 - √2)/4](2 - 2√2)^n.

(b) The homogeneous part of the recurrence relationan = 2an−1 is given by the characteristic equation r - 2 = 0, which has the root r = 2. Therefore, the general solution of the homogeneous part is an = c2·2^n. To find a particular solution of the non-homogeneous part an = 3 · 2^n, we can try the form an = A·2^n. Substituting this into the recurrence relation, we get A·2^n = 3·2^n, which implies A = 3. Therefore, a particular solution of the non-homogeneous part is an = 3·2^n. The general solution of the recurrence relation is the sum of the homogeneous and non-homogeneous parts, which is an = c2·2^n + 3·2^n. Using the initial condition a0 = 1, we get c2 = 1 - 3 = -2. Therefore, the solution to the recurrence relation is an = -2·2^n + 3·2^n = 2^n(3 - 2^n).

Example that demonstrates the contrapositive of the limit comparison test. Let's consider a pair of series an and bn with positive terms, where lim(n→∞)(an/bn) = 0, bn diverges, but an converges.

Let's define the series an and bn as follows:
- an = 1/\(n^2\)
- bn = 1/n

Now, let's examine the limit:
lim(n→∞)(an/bn) = lim(n→∞)((1/\(n^2\)) / (1/n))

To simplify the limit expression, we multiply both numerator and denominator by \(n^2\):
lim(n→∞)(\(n^2\)(1/\(n^2\)) / \(n^2\)(1/n)) = lim(n→∞)(n/\(n^2\)) = lim(n→∞)(1/n)

As n approaches infinity, the limit becomes:
lim(n→∞)(1/n) = 0

Now, let's check the convergence of the series an and bn:
- an = Σ(1/\(n^2\)) is a convergent p-series with p = 2 > 1.
- bn = Σ(1/n) is a divergent p-series with p = 1.

Thus, we have provided an example of a pair of series an and bn with positive terms, where lim(n→∞)(an/bn) = 0, bn diverges, but an converges. This demonstrates the contrapositive of the limit comparison test, as requested.

Answer:

SA = 94 ft²

Step-by-step explanation:

To find the surface area of a rectangular prism, you can use the equation:

SA = 2 ( wl + hl + hw )

SA = surface area of rectangular prism

l = length

w = width

h = height

In the image, we are given the following information:

l = 4

w = 5

h = 3

Now, let's plug in the information given to us to solve for surface area:

SA = 2 ( wl + hl + hw)

SA = 2 ( 5(4) + 3(4) + 3(5) )

SA = 2 ( 20 + 12 + 15 )

SA = 2 ( 47 )

SA = 94 ft²

Unlike the range which describes all the y-values used by the graph, the domain describes the x-values used by the graph.  The domain is basically describing how far left to right the graph goes.

What's tricky about this is to recognize that the graph goes on forever to both the left and the right.  It never stops on either side.

In words, we'd say it goes from negative infinity to positive infinity.

As an inequality, we'd write this as Answer D.

Answer: yes, Rachelle is correct.

Step-by-step explanation:

first, if you're moving left, you're subtracting from the x value.

next, if you're moving down then you're subtracting from the y value.

For a normal distribution, the skewness and kurtosis measures are as follows: Option B. 0 and 3.

Skewness is a measure of the asymmetry of a probability distribution. Skewness is a measure of the degree of asymmetry in the probability distribution of a random variable around its mean.

When the skewness is 0, the normal distribution is symmetrical.

Kurtosis is a measure of the degree of peakiness, or flatness, of a probability distribution.

For a normal distribution, kurtosis equals 3. In comparison to the normal distribution, distributions with kurtosis greater than 3 have a more pointed peak and longer tails, while distributions with kurtosis less than 3 have a less pointed peak and shorter tails.

Therefore, for a normal distribution, the skewness and kurtosis measures are 0 and 3, respectively. Hence, the correct option is B. 0 and 3.

To find the displacement of the weight for \( t > 0 \) given the conditions provided, we can use the equation of motion for a spring-mass system.

By solving this second-order linear homogeneous differential equation, we can determine the displacement as a function of time.

The equation of motion for a spring-mass system is given by

\( m\frac{{d^2x}}{{dt^2}} + kx = F(t) \),

where \( m \) is the mass, \( x \) is the displacement, \( k \) is the spring constant, and \( F(t) \) is the external force.

In this case, the mass is 4 lb, the spring constant can be found by Hooke's law as

\( k = \frac{{mg}}{{\Delta x}} \),

where \( g \) is the acceleration due to gravity and \( \Delta x \) is the displacement in equilibrium. The external force is given as

\( F(t) = 25\sin(8t) \) N.

To solve the equation of motion, we first convert the given quantities to SI units. Then we substitute the values into the equation and solve for the displacement \( x(t) \) as a function of time.

Answer:

10 adult tickets cost £75 , 20 child tickets cost £60

Step-by-step explanation:

let a be the cost of an adult ticket and c the cost of a child ticket , then

4a + c = 33 → (1)

2a + 7c = 36 → (2)

multiplying (2) by - 2 and adding to (1) will eliminate a

- 4a - 14c = - 72 → (3)

add (1) and (3) term by term to eliminate a

0 - 13c = - 39

- 13c = - 39 ( divide both sides by - 13 )

c = 3

substitute c = 3 into either of the 2 equations and solve for a

substituting into (1)

4a + 3 = 33 ( subtract 3 from both sides )

4a = 30 ( divide both sides by 4 )

a = 7.5

the cost of an adult ticket is £7.50

then 10 adult tickets cost 10 × £7.50 = £75

the cost of a child ticket is £3

the cost of 20 child tickets is 20 × £3 = £60
