Find the missing term of the following sequence. . . . –2, __, 456, . . .

Distance from Town X to Town Y = 100 miles

Distance = Speed x Time

Speed while going = 50 mph , Speed while returning = 40 mph

Let the time taken while going = t hours

So, the time taken while returning = t + 0.5 hours

So, 50 t = 40 ( t + 0.5)

50 t = 40x + 20

50 t - 40 t = 10x = 20

10 t = 20

t = 20 / 10 = 2

Hence, distance = 50 t = 40 ( t + 0.5 )

= 50 x 2 ; or 40 x 2.5 = 100

The distance from Town X to Town Y is 180 miles. This is determined by setting up and solving an equation based on the given speeds and time difference.

The subject of this question is Mathematics, specifically it is a problem in a genre called distance, speed, time problems. Let's denote the distance from Town X to Town Y as 'd' miles. The man covers this distance twice - once going and once coming back. The time he takes to travel from X to Y is d/50 and to travel back from Y to X is d/40.

So, the actual total time he spends travelling is (d/50 + d/40) hours. If he made the round trip at an average speed of 45 mph, he would take (2d/45) hours (distance = speed x time). Given that the actual journey took a 1/2 hour longer than this, we can create the following equation:

(d/50 + d/40) = 2d/45 + 1/2.

Solving this equation for 'd', we get d = 180 miles. So, the answer is that the distance from Town X to Town Y is 180 miles.

The true statements about the opposite of -12 are that the opposite of the opposite of -12 is -12 and -12 and its opposite are located the same distance from zero on a number line. The opposite of -12 is +12.

In mathematics, the opposite of a number is also called its additive inverse, which is the number that, when added to the original number, will result in zero. −12 and its opposite, +12, are indeed located on opposite sides of zero on a number line, not on the same side. The second statement is true, the opposite of the opposite of −12 is indeed −12. The third statement is incorrect, the opposite of −12 is +12, not −112. The fourth statement is also true, −12 and its opposite are both 12 units away from zero on a number line, so they're at the same distance from zero.

Answer:true!!!

Step-by-step explanation:

In the interval [-3, 0] the local minimum is -16 and In the interval [0, 3], the local maximum is 4 and local minimum is -3.

The local maxima and minima are the input values for which the function gives the maximum and minimum output values respectively. The y - coordinate of local maxima is called local maximum and that of local minima is called as local minimum.

Given is a graph of a function.

In the graph the local maximum is the y - coordinate that has maximum value at any specific input. Similarly, local maximum is the y - coordinate that has minimum value at any specific input.

PART A

In the interval [-3, 0], the local minimum is -16

PART B

In the interval [0, 3], the local maximum is 4 and local minimum is -3.

Therefore, in the interval [-3, 0] the local minimum is -16 and In the interval [0, 3], the local maximum is 4 and local minimum is -3.

Using the binomial distribution, it is found that there is a 0.1296 = 12.96% probability that he makes all 4 shots.

-------------------------------

For each throw, the player either makes it or misses it. The probability of making each throw is the same, independent of other throws, thus, the binomial distribution is used to solve this question.

Binomial probability distribution:

The binomial probability is the probability of exactly x successes on n repeated trials, with X having two possible outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of a success on a single trial.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 4) = C_{4,4}.(0.6)^{4}.(0.4)^{0} = 0.1296[/tex]

0.1296 = 12.96% probability that he makes all 4 shots.

To find the height of the rectangular prism, divide the volume by the area of the base.

To find the height of the rectangular prism, we need to divide the volume by the area of the base. The formula for the volume of a rectangular prism is V = lwh, where l, w, and h represent the length, width, and height, respectively. The formula for the area of the base is A = lw.

In this case, the volume is given as (x3-3x2+5x-3) and the area of the base is (x -2). So, we need to divide the volume by the area of the base, which gives us:

(x3-3x2+5x-3)/(x -2).

The reported probability of 1 in 101,270 for matching all four lotto numbers is equivalent to a decimal probability of approximately 0.00000987.

Explanation:

The Louisiana Lottery Commission's lotto game entails participants matching all 4 numbers out of a pool of 41. The reported probability of achieving this feat is 1 in 101,270. To express this probability, we utilize the ratio of successful outcomes to total possible outcomes. Consequently, the probability of matching all four numbers is 1/101,270, equivalent to approximately 0.00000987 in decimal form. This minute probability underscores the challenging nature of the lotto game, highlighting the rarity of successfully predicting and matching the specified set of numbers within the given range.

The population of the small town percent decreased by approximately 8.4%.

To find the percent decrease in the population of the small town, we can use the formula for percent decrease:

Percent Decrease = [(Initial Value - Final Value) / Initial Value] * 100

Given that the initial population was 983 and the final population was 901, we can plug these values into the formula:

Percent Decrease = [(983 - 901) / 983] * 100

Now, calculate the numerator:

Percent Decrease = [82 / 983] * 100

Divide and multiply:

Percent Decrease = 0.0835 * 100

Now, calculate the percent decrease to the nearest tenth of a percent:

Percent Decrease ≈ 8.4%

So, the population of the small town decreased by approximately 8.4%.

Final answer:

The greatest common factor (GCF) of the numerator and denominator in the rational expression (7x+14)/(2x²+x-6) is x+2. Thus, option C is correct.

Explanation:

To find the greatest common factor (GCF) of the numerator and denominator of the given rational expression (7x+14)/(2x²+x-6), we need to factor both the numerator and the denominator separately.

For the numerator 7x+14, we can factor out a 7:

7x + 14 = 7(x + 2)

For the denominator 2x² + x - 6, we need to factor it as a quadratic expression. This can be done by finding two numbers that multiply to give -12 (the product of the coefficient of x² and the constant term) and add up to 1 (the coefficient of x). These numbers are 3 and -4, so the denominator can be factored as:

2x² + x - 6 = (2x - 3)(x + 2)

Now we can see that the common factor between the numerator and the denominator is x + 2. Therefore, the GCF is x + 2, which corresponds to option (c).
