Step-by-step explanation:

t50 = t1 + (n - 1)(d)

= 7 + (50 - 1) (5)

= 7 + (49)(5)

= 7 + 245

= 252

Answer:

The 50ᵗʰ term of this sequence is 252

Step-by-step explanation:

Here,

First Term = a₁ = 7

Common Difference = (d) = 5

Now, For 50ᵗʰ term, n = 50

aₙ = a + (n - 1)d

a₅₀ = 7 + (50 - 1) × 5

a₅₀ = 7 + 49 × 5

a₅₀ = 7 + 245

a₅₀ = 252

Thus, The 50ᵗʰ term of this sequence is 252

Therefore, the 90% confidence interval for the population mean is (120.89, 129.71).

To calculate the confidence interval for the population mean, we can use the formula:

Confidence Interval = sample mean ± (critical value) * (standard deviation / √n)

Given:

Sample mean  = 125.3

Standard deviation = 13.42

Sample size (n) = 25

First, we need to determine the critical value corresponding to a 90% confidence level. Since the population is assumed to have a normal distribution, we can use the Z-score table or a calculator to find the critical value. For a 90% confidence level, the critical value is approximately 1.645.

Substituting the values into the formula:

Confidence Interval = 125.3 ± 1.645 * (13.42 / √25)

Calculating the values:

Confidence Interval = 125.3 ± 1.645 * 2.684

Confidence Interval = 125.3 ± 4.414

Finally, rounding to two decimal places:

Confidence Interval = (120.89, 129.71)

Therefore, the 90% confidence interval for the population mean is (120.89, 129.71).

According to the design, both the PokerHand and BlackjackHand classes may, but are not required to override the methods of the parent Hand class. The Hand class provides the basic functionality for a player's hand of cards, such as adding cards to the hand, calculating the total value of the hand, and displaying the cards in the hand.

However, since Poker and Blackjack have their own unique rules and gameplay mechanics, the PokerHand and BlackjackHand classes may need to override certain methods to tailor them to their specific game.

For example, in Blackjack, the value of an Ace card can be either 1 or 11 depending on the situation, so the BlackjackHand class may need to override the calculateTotalValue method to take this into account.

Additionally, both the PokerHand and BlackjackHand classes may choose to override the toString method to display the hand in a way that makes sense for their respective game. For instance, in Poker, players often refer to their hand by its ranking, such as "two pair" or "flush", so the PokerHand class may choose to display the hand in this way.

Overall, while the Hand class provides a foundation for both PokerHand and BlackjackHand, allowing them to inherit common functionality, the ability to override certain methods allows them to adapt to the specific rules and requirements of their respective games.

ANSWER:

v = 3 is only a solution to equations 1 and 5.

STEP-BY-STEP EXPLAINATION:

Equation 1:

\( \frac{v}{3} + 9 = 10\)

\( \frac{v}{3} = 10 - 9\)

\( \frac{v}{3} = 1\)

\(v = 1(3)\)

\(v = 3\)

Therefore, v = 3 is a solution.

Equation 2:

\(4 = 7v - 24\)

\(4 + 24 = 7v\)

\(28 = 7v\)

\( \frac{28}{7} = v\)

\(4 = v\)

Therefore, v = 3 is not a solution.

Equation 3:

\(16 = 2 + 5v\)

\(16 - 2 = 5v\)

\(14 = 5v\)

\( \frac{14}{5} = v\)

Therefore, v = 3 is not a solution.

Equation 4:

\(5 - 7v = 19\)

\( - 7v = 19 - 5\)

\( - 7v = 14\)

\(v = \frac{14}{ - 7} \)

\(v = - 2\)

Therefore, v = 3 is not a solution.

Equation 5:

\(3 + 2v = 9\)

\(2v = 9 - 3\)

\(2v = 6\)

\(v = \frac{6}{2} \)

\(v = 3\)

Therefore, v = 3 is a solution.

(a) The probability that a randomly chosen wedge of cheddar cheese is greater than 10.14 is found using the standard normal distribution as follows:

P(Z > z) = P(Z > (10.14 - µ)/σ)

= P(Z > (10.14 - 10.2)/0.2)

≈ 0.3085.

Therefore, the probability is approximately 0.3085.

(b) If a sample of 16 is randomly chosen, then the distribution of the sample mean weight is approximately normal with a mean of 10.2 ounces and a standard deviation of σ/√n,

Where n = 16.

The sample standard deviation is given by σ = 0.2, so the standard deviation of the sample mean weight is:

σ/√n = 0.2/√16

= 0.05.

Therefore, the distribution of the sample mean weight is approximately normal with a mean of 10.2 ounces and a standard deviation of 0.05 ounces.

(c) The probability that the sample mean weight of this sample of 16 is less than 10.14 is found using the standard normal distribution as follows:

P(Z < z) = P(Z < (10.14 - µ)/(σ/√n))

= P(Z < (10.14 - 10.2)/(0.2/√16))

≈ P(Z < -1.6)

≈ 0.0548.

Therefore, the probability is approximately 0.0548.

(d) The probability that the sample mean weight of this sample of 16 is greater than 10.14 is found using the standard normal distribution as follows:

P(Z > z) = P(Z > (10.14 - µ)/(σ/√n))

= P(Z > (10.14 - 10.2)/(0.2/√16))

≈ P(Z > -1.6)

≈ 0.9452.

Therefore, the probability is approximately 0.9452.

(e) The probability that the sample mean weight of this sample of 16 is between 10.14 and 10.3 is found

Using the standard normal distribution as follows:

P(a < Z < b) = P((a - µ)/(σ/√n) < Z < (b - µ)/(σ/√n))

= P((10.14 - 10.2)/(0.2/√16) < Z < (10.3 - 10.2)/(0.2/√16))

≈ P(-1.6 < Z < 2)

≈ 0.9452 - 0.0548

= 0.8904.

Therefore, the probability is approximately 0.8904.

(f) Let x be the average weight of a sample of these 16 cheese wedges that is below some value z.

Then, the probability that x is less than z is 0.07.

Using the standard normal distribution, we can find the z-score such that

P(Z < z) = 0.07 as follows:

z = inv Norm(0.07)

≈ -1.4758.

Therefore, the average weight of a sample of these 16 cheese wedges that is below the value z is:

x = µ + z(σ/√n)

= 10.2 + (-1.4758)(0.2/√16)

≈ 10.0625.

Therefore, there is only a 7% chance that the average weight of a sample of these 16 cheese wedges will be below 10.0625.

Answer: 4x^2+16x-2

Step-by-step explanation:

You need to use BEDMAS order. (Brackets, exponents, division & multiplication left to right, addition & subtraction left to right)

Since there is nothing else you can do to the brackets, leave it for now.

There is also nothing you can do to the exponents, since you can't square a variable you don't know the value of.

Now, we do division & multiplication (there is no division in this case)

2x(3x + 4)−2x^2+8x-2 (start with the underlined section, using distributive property)

6x^2+8x−2x^2+8x-2

Now, since this is not an equation (no equal sign) but an expression, we just need to combine like terms.

6x^2+8x−2x^2+8x-2 (start with the x^2 terms. 6-2=4, so we end up with 4x^2)

4x^2+8x+8x-2 (now move on to the x terms. 8+8=16, so we end up with 16x)

4x^2+16x-2

And we're done! No more like terms to combine!

∂z/∂s = 3cos(t)/y, ∂z/∂t = 3s*cos(t)/y - sin(s)/x (using the chain rule to differentiate each term and substituting the given expressions for x and y)

To find ∂z/∂s and ∂z/∂t using the chain rule, we start by finding the partial derivatives of z with respect to x and y, and then apply the chain rule.

First, let's find ∂z/∂x and ∂z/∂y.

∂z/∂x = ∂/∂x [ln(5x^3y)]

= (1/5x^3y)  ∂/∂x [5x^3y]

= (1/5x^3y) 15x^2y

= 3/y

∂z/∂y = ∂/∂y [ln(5x^3y)]

= (1/5x^3y) ∂/∂y [5x^3y]

= (1/5x^3y)  5x^3

= 1/x

Now, using the chain rule, we can find ∂z/∂s and ∂z/∂t.

∂z/∂s = (∂z/∂x)  (∂x/∂s) + (∂z/∂y)  (∂y/∂s)

= (3/y)  (cos(t)) + (1/x)  (0)

= 3cos(t)/y

∂z/∂t = (∂z/∂x)  (∂x/∂t) + (∂z/∂y)  (∂y/∂t)

= (3/y) * (scos(t)) + (1/x)  (-sin(s))

= 3scos(t)/y - sin(s)/x

Therefore, ∂z/∂s = 3cos(t)/y and ∂z/∂t = 3s*cos(t)/y - sin(s)/x.

Step-by-step explanation:

the general form of the coefficient Bk is 0 for k > 0 and 8/3 for k = 0.

The coefficient A0 is given by:

A0 = (1/L) ∫f(x)dx from x=0 to x=L

where L is the period of the function, and in this case, L = 3.

A0 = (1/3) ∫0^3 1 dx + (1/3) ∫0^4 0 dx + (1/3) ∫4^5 1 dx

= (1/3) (3 + 0 + 1)

= 4/3

For k > 0, the coefficient Ak is given by:

Ak = (2/L) ∫f(x) cos(kπx/L) dx from x=0 to x=L

Ak = (2/3) ∫0^3 cos(kπx/3) dx + 0 + (2/3) ∫4^5 cos(kπx/3) dx

= (2/3) [1/kπ sin(kπx/3)] from x=0 to x=3 + (2/3) [1/kπ sin(kπx/3)] from x=4 to x=5

= (2/3kπ) [sin(kπ) - sin(0) + sin(kπ/3) - sin(4kπ/3)]

= (4/3kπ) [cos(kπ/3) - cos(5kπ/3)]

For k = 0, the coefficient Bk is given by:

B0 = (2/L) ∫f(x) dx from x=0 to x=L

B0 = (2/3) ∫0^3 1 dx + (2/3) ∫4^5 1 dx

= (2/3) (3 + 1)

= 8/3

For k > 0, the coefficient Bk is given by:

Bk = (2/L) ∫f(x) sin(kπx/L) dx from x=0 to x=L

Bk = 0, since f(x) is an even function and sin(kπx/L) is an odd function, so their product is odd and integrates to 0 over a symmetric interval.

Tanya should play The second game to win more.

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

Given, Tanya is considering playing a game at the fair. There are three different ones to choose from, and it costs $2 to play a game. The probabilities associated with the games are given in the table.

From the general formula of weighted possibility :

Total weighted possibility = Sum of the weighted probability of desired outcomes - the weighted possibility of undesired outcomes

In our case,

For first game

The sum of the weighted possibility of desired outcomes = 0.20*1 + 0.25 *4

The sum of the weighted possibility of desired outcomes = 1.20

the weighted possibility of undesired outcomes = 0.55 * 2 = 1.10

Thus,

Total weighted desired possibility = 1.20 - 1.10

Total weighted desired possibility = 0.10

For second game

The sum of the weighted possibility of desired outcomes =0.35*1 + 0.50 *4

The sum of the weighted possibility of desired outcomes = 2.35

the weighted possibility of undesired outcomes = 0.15 * 2 = 0.30

Thus,

Total weighted desired possibility = 2.35 - 0.30

Total weighted desired possibility =  2.05

For third game

The sum of the weighted possibility of desired outcomes = 0.60*1 + 0.20*4

The sum of the weighted possibility of desired outcomes = 1.40

the weighted possibility of undesired outcomes = 0.20 * 2 = 0.40

Thus,

Total weighted desired possibility =1.40 - 0.40

Total weighted desired possibility = 1

Let's call the number of pairs of socks Coy needs to buy "x".

If he shops at Sport 'n Stuff, the cost will be:

Cost at Sport 'n Stuff = $22 (for cleats) + $4x (for socks)

If he shops at Sports Superstore, the cost will be:

Cost at Sports Superstore = $28 (for cleats) + $3.25x (for socks)

We want to find the value of "x" for which shopping at Sports Superstore is cheaper than shopping at Sport 'n Stuff. In other words, we want:

Cost at Sports Superstore < Cost at Sport 'n Stuff

Substituting the expressions we found earlier, we get:
