Step-by-step explanation:

The 45th term of the arithmetic sequence is 178. Option C

Given the arithmetic sequence formula as;

an = 2 + 4(n − 1)

we have n = 45

Let's substitute the value of 'n' into the formula;

a = 2 + 4( 45 - 1)

expand the bracket

a = 2 + 4(44)

a = 2 + 176

a = 178

The 45th term is 178

Thus, the 45th term of the arithmetic sequence is 178. Option C

Step-by-step explanation:

Answer:

b = sp

Step-by-step explanation:

box = seeds per packet

The given relation can be used to find the total number of seeds in box b, using the equation b = sp. Hence, 3rd option is the right choice.

Equations are relations shown between two equal algebraic expressions.

We are given a box of sunflower seeds, containing p packets of seeds, each of which contains s number of seeds.

We are asked to write an equation that can be used to find the total number of seeds in the box, b.

We know that the box contains p packets of seeds.

In 1 packet we have s number of seeds.

∴ In p packets, we will have an s*p number of seeds or sp seeds.

Since the box contains p packets and the total number of seeds in the box is b, then we can say that

b = the number of seeds in p packets

or, b = sp, which is the required equation.

∴ The given relation can be used to find the total number of seeds in box b, using the equation b = sp. Hence, 3rd option is the right choice.

To solve the compound inequality we need to solve each inequality, then we have:

Now we need to remember that the word OR means the union of the solution sets for each inequality then the solution is:

The coordinates of the point at 3/4 of the distance from A to B from A is (-3.5, 1.25)

The coordinates of point A = (-5, -4),

The coordinates of the point B = (-3, 3)

Let the point at the distance 3/4 from A to B = P

The coordinates of point 3/4 from A to B = P

At the x-coordinate, the distance from B to A is =  -3-(-5) = 2 units.

At the y-coordinate, the distance from B to A is = 3-(-4) = 7 units.

Hence, the coordinates of P = (-5 + (3/4×(x-coordinate), -4 + 3/4×(y-coordinate)

                                            P = (-5 + (3/4×(2), -4 + 3/4×(7))

Answer:

To find out how many points Nicky needs to score in her next game, we can use the formula for the mean (also known as the average) of a set of numbers:

mean = (sum of all numbers) / (number of numbers)

We know that Nicky has played three games and scored, and points in them. So the sum of all her points is:

sum=18+22+28

sum=68

We also know that Nicky wants to have a mean of 25 points per game, and she has played three games already. If we add the score from her next game to the sum, we will have the total number of points she has scored in four games.

By using the unit conversion method, 2 million seconds converted to days are equal to 23 days.

A unit conversion expresses the same aspect as another unit of measurement. For example, time can be expressed in minutes rather than hours, and distance can be represented from miles to kilometers, feet, or any other unit of measurement.

In this situation, you need to convert between seconds and days:

A day consists of 24 hours. Therefore, the fraction 24 hours/day is equal to 1. There is no value change when multiplying a number by 1. The same holds true for the conversion factors 1 hour/60 minutes and 1 minute/60 seconds.

If you multiply 2,000,000 seconds (2 million seconds) by these conversion factors, you will change the seconds to days:

2,000,000 sec. x (1 min/60 sec.) x (1 hour/60 min) x (1 day / 24 hours)

Therefore, all that is required is to divide 2,000,000 by the product of 60, 60, and 24.

(2,000,000) / (60*60*24) = 2,000,000 / 86,400 = 23.148 days ≈ 23 days

The (f∘g)(x) = -5x + 1.

The solutions are:

Part A: (f+g)(x) = -4x + 1

Part B: (f-g)(x) = 6x + 7

Part C: (f∘g)(x) = -5x + 1

To determine the values of (f+g)(x), (f-g)(x), and (f∘g)(x) for the given        linear functions f(x) = x + 4 and g(x) = -5x - 3, we'll perform the necessary operations.

Part A: (f+g)(x)

To find (f+g)(x), we add the two functions together:

(f+g)(x) = f(x) + g(x)

= (x + 4) + (-5x - 3)

= x - 5x + 4 - 3

= -4x + 1

Therefore, (f+g)(x) = -4x + 1.

Part B: (f-g)(x)

To find (f-g)(x), we subtract g(x) from f(x):

(f-g)(x) = f(x) - g(x)

= (x + 4) - (-5x - 3)

= x + 5x + 4 + 3

= 6x + 7

Therefore, (f-g)(x) = 6x + 7.

Part C: (f∘g)(x)

To find (f∘g)(x), we substitute g(x) into f(x):

(f∘g)(x) = f(g(x))

= f(-5x - 3)

= -5x - 3 + 4

Using the normal approximation to the binomial, there is a 0.9713 = 97.13% probability that the sum of these variables is less than 60.

This problem is incomplete, but researching it on a search engine, it asks the probability that the sum of these Bernoulli variables is of less than 60.

The z-score of a measure X of a normally distributed variable with mean \(\mu\) and standard deviation \(\sigma\) is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The binomial distribution is a series of n Bernoulli trials with p probability of a success on each trial, hence the parameters for the binomial distribution are given as follows:

n = 100, p = 0.5.

The mean and the standard deviation are given by:

Using continuity correction, the probability that the sum is less than 60 is P(X < 59.5), which is the p-value of Z when X = 59.5, hence:

\(Z = \frac{X - \mu}{\sigma}\)

Z = (59.5 - 50)/5

Z = 1.9

Z = 1.9 has a p-value of 0.9713.

Hence there is a 0.9713 = 97.13% probability that the sum of these variables is less than 60.

The term that describes an event that increases the likelihood of a response being repeated is known as reinforcement.

Reinforcement can be defined as any consequence that strengthens or increases the probability of a behavior occurring again in the future. This can include positive reinforcement, which involves adding a desirable consequence after a behavior, or negative reinforcement, which involves removing an aversive consequence after a behavior. Both types of reinforcement have been shown to be effective in increasing the likelihood of a behavior being repeated.

Overall, understanding the concept of reinforcement is essential in the field of psychology, particularly in the areas of behaviorism and behavior modification. By providing positive consequences after desired behaviors, individuals can be motivated to continue engaging in those behaviors, which can lead to long-term positive changes. Reinforcement can also be used to shape new behaviors or replace unwanted behaviors with more desirable ones.

Given the production function, (K, L) = 12K1/3L1/2 - 4K – 1, where K > 0,1 ≤ 20, L = π. We need to find the profit-maximizing level of K.

Profit maximization occurs where Marginal Revenue Product (MRP) is equal to the Marginal Factor Cost (MFC).To determine the optimal value of K, we will derive the expressions for MRP and MFC.

Marginal Revenue Product (MRP) is the additional revenue generated by employing an additional unit of input (labor) holding all other factors constant. MRP = ∂Q/∂L * MR where, ∂Q/∂L is the marginal physical product of labor (MPPL)MR is the marginal revenue earned from the sale of output.

MRP = (∂/∂L) (12K1/3L1/2) * MRLMPPL = 6K1/3L-1/2MR = P = 10Therefore, MRP = 6K1/3L1/2 * 10 = 60K1/3L1/2The Marginal Factor Cost (MFC) is the additional cost incurred due to the use of one additional unit of the input (labor) holding all other factors constant.

MFC = Wages = 5 Profit maximization occurs where MRP = MFC.60K1/3L1/2 = 5K1/3Multiplying both sides by K-1/3L-1/2, we get;60 = 5K2/3L-1Therefore,K2/3 = 12Hence, K = (12)3/2 = 20.784Profit maximizing value of K is 20.784.

Answer:

The cost of 30 gallons of gas is $74.7.

Step-by-step explanation:

Step 1 of 3

Here we need to find the cost of 30  gallons.

Given that the price that Tyler pays for gas varies directly with the number of gallons he buys.

The cost of 24  gallons is $59.76  to him.

Let, x  be the number of gallons and y  be the cost or price for gas.

Use the formula for direct variation which is given by y=kx.

Step 2 of 3

Now substitute the value y=$59.76 and x=24.

Put value in y=kx, we get

\($$\begin{aligned}&59.76=k \times 24 \\&k=2.49\end{aligned}$$\)

Substitute value of k is y=kx, we get y=2.49x

Step 3 of 3

Now we need to find the value of y that is the cost for 30 gallons.

Again use direct variation formula y=kx and value of k and x, we get \($y=2.49 \times 30$\)

\($$y=74.7$$\)

The statement "For every x∈EXPR, na(x) = 1 + nop(x)" is proven using induction. For any string x in the set {a, b}∗ that starts with 'a' and ends with 'b', it is shown that x contains the substring 'ab'.

To prove the statement, we will use mathematical induction.

Step 1: Base Case

For the base case, let x be the string 'a'. In this case, na(x) = 1 (as there is one 'a') and nop(x) = 0 (as there are no operators). Thus, na(x) = 1 + nop(x), satisfying the equation.

Step 2: Inductive Hypothesis

Assume that for some string x of length k, which starts with 'a' and ends with 'b', the statement holds true: na(x) = 1 + nop(x).

Step 3: Inductive Step

Consider a string x' = xa, where a is any character ('a' or 'b'). We need to show that na(x') = 1 + nop(x').

Since x starts with 'a' and ends with 'b', we can represent x as x = yb, where y is a substring of x with length k - 1. Then x' can be represented as x' = yba.

Now, let's analyze the number of 'a's and operators in x' using na(x') and nop(x'):

na(x') = na(yba) = na(y) + 1 (as there is an additional 'a')

nop(x') = nop(yba) = nop(y) + 1 (as there is an additional operator)

By the inductive hypothesis, we know that na(y) = 1 + nop(y). Substituting these values, we have:

na(x') = na(y) + 1 = 1 + nop(y) + 1 = 2 + nop(y)

nop(x') = nop(y) + 1

Comparing na(x') and nop(x'), we see that na(x') = 1 + nop(x'), which completes the inductive step.

By the principle of mathematical induction, the statement is proven for all strings x in {a, b}∗ that start with 'a' and end with 'b'.
