Step-by-step explanation:

To find miles per hour, divide miles by hours:

  (15 mi)/(3 h) = 15/3 mi/h = 5 mi/h

__

To find distance, multiply speed by time.

  (5 mi/h) × (10 h) = 50 mi

In a trial of 10 versus 500, the experimental probability is expected to be closer to the theoretical probability when there are more trials (500 in this case).

The experimental probability and theoretical probability can be compared in a trial of 10 versus 500 by understanding the concepts behind each type of probability.

Theoretical probability is based on mathematical calculations and is determined by analyzing the possible outcomes of an event. It relies on the assumption that the event is equally likely to occur, and it can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes. Theoretical probability is often considered the expected or ideal probability.

On the other hand, experimental probability is determined through actual observations or experiments. It involves conducting the event multiple times and recording the outcomes to determine the relative frequency of a specific outcome. The experimental probability is an estimation based on the observed data.

In the given trial of 10 versus 500, we can expect the experimental probability to be closer to the theoretical probability when the number of trials (or repetitions) is larger. In this case, with 500 trials, the experimental probability is likely to be a more accurate representation of the true probability.

When the number of trials is small, such as only 10, the experimental probability may deviate significantly from the theoretical probability. With a smaller sample size, the observed outcomes may not accurately reflect the expected probabilities calculated theoretically.

In summary, in a trial of 10 versus 500, the experimental probability is expected to be closer to the theoretical probability when there are more trials (500 in this case). As the number of trials increases, the observed frequencies are likely to converge towards the expected probabilities calculated theoretically.

Answer:

m ≤ 5

Step-by-step explanation:

I will begin by assuming m to be the number.

Then, the sum of m and 3 is: m + 3.

The symbol for "less than or equal to" is ≤.

So we form an inequality, like this :

m + 3 ≤ 8

To find m subtract 3 on each side:

m ≤ 5

Therefore, m ≤ 5.

Answer: 6 pieces

Step-by-step explanation:

(3/4) of a foot cut into 1/8th piece.

(3/4) divided by (1/8) = 6.

There are 6 pieces of 1/8th lengths of wood in the 3/4 board that James originally has.

The ratio of the length of a tile in the model to the length of an actual tile is 1/8.

The ratio of the area of a tile in the model to the area of an actual tile is 1/64.

From the information, it should be noted that in the model, each tile has length 1/3in and width 1/4 in and the actual tiles have length 1/4 ft and width 3/16ft .

The ratio of the length of a tile in the model to the length of an actual tile will be:

= 1/4 ÷ 2

= 1/4 × 1/2

= 1/8

The ratio of the area of a tile in the model to the area of an actual tile is (1/4 × 1/6) / (2 × 4/3)

The LCD of 1/(x+2)^2, 3/(x-2)^2, and 4/(x^2-4) is (x+2)^2(x-2)^2(x+2)(x-2) = (x+2)^3(x-2)^3.

To find the lowest common denominator (LCD) of three fractions, we need to identify the factors of each denominator and select those factors that are common to all denominators.The given fractions are: 1/ (x+2)^2, 3/ (x-2)^2, and 4/ (x^2-4).

The first denominator (x+2)^2 can be factored using the formula for the difference of two squares. The denominator of 3/(x-2)^2 can also be factored using the formula for the difference of two squares.

Finally, the denominator of 4/(x^2-4) can be factored using the formula for the difference of two squares and the formula for the sum of two squares.

So, 1/(x+2)^2, 3/(x-2)^2, and 4/(x^2-4) can be rewritten as follows:1/ (x+2)^2 = A/(x+2) + B/(x+2)^2. Multiplying both sides by (x+2)^2 gives:1 = A(x+2) + B ... (1)3/ (x-2)^2 = C/(x-2) + D/(x-2)^2.

Multiplying both sides by (x-2)^2 gives:3 = C(x-2) + D ... (2)4/ (x^2-4) = E/(x-2) + F/(x+2). Multiplying both sides by (x^2-4) gives:4 = E(x-2)(x+2) + F(x+2)(x-2) ... (3)

Now, we need to solve these equations for A, B, C, D, E, and F. First, we will solve equation (1) for A and B by substituting x = -2, which gives A = -1/4. Then we will substitute x = -2 again and solve for B, which gives B = 1/4. Next, we will solve equation (2) for C and D by substituting x = 2, which gives C = 3/4.

Then we will substitute x = 2 again and solve for D, which gives D = -3/4. Finally, we will solve equation (3) for E and F by substituting x = 2 and x = -2, which gives E = 1/2 and F = 1/2.

Now, we have A = -1/4, B = 1/4, C = 3/4, D = -3/4, E = 1/2, and F = 1/2. The LCD is the product of all the factors that appear in the denominators of the fractions, each raised to the highest power that appears.

Step-by-step explanation:

To accumulate $400,000 for retirement in 35 years with a 6% interest rate, you would need to save approximately $2,090.77 per year.

We can use the formula for calculating the future value of an ordinary annuity.

The formula for the future value of an ordinary annuity is:

FV = P * ((1 + r)^n - 1) / r

In this scenario:

FV = $400,000

r = 6% = 0.06

n = 35 years

Let's substitute the values into the formula and solve for P:

\($400,000 = P * ((1 + 0.06)^35 - 1) / 0.06\)

Solving for the annual payment (P) required:

\(P = ($400,000 * 0.06) / ((1 + 0.06)^{35} - 1)\)

Using a calculator, we can evaluate this expression:

P ≈ $2,090.77

Therefore, to accumulate $400,000 for retirement in 35 years with a 6% interest rate, you would need to save approximately $2,090.77 per year.

The number of sodas sold at the baseball game was 119, while the number of hot dogs sold was 72.

Let's assume the number of sodas sold as 'x' and the number of hot dogs sold as 'y'.

According to the problem, the total number of sodas and hot dogs sold is 191, so we can write the equation:

x + y = 191   ...(1)

The problem also states that the number of hot dogs sold was 47 less than the number of sodas sold. Mathematically, we can express this as:

y = x - 47   ...(2)

To find the values of x and y, we can solve the system of equations (1) and (2). Substituting equation (2) into equation (1), we have:

x + (x - 47) = 191

Simplifying the equation:

2x - 47 = 191

2x = 191 + 47

2x = 238

Dividing both sides by 2:

x = 238/2

x = 119

Substituting the value of x back into equation (2):

y = 119 - 47

y = 72

As a result, the total amount of sodas sold is 119, and the total amount of hot dogs sold is 72.

Answer:

The cost of x pounds of apples is given by the equation:

C(x) = $2.49*x

Where the domain is the set of the possible values of x and the range is the set of the possible values of C(x)

We want to find the range of possible prices that you can pay.

The minimum number of pounds of apples that you can buy is 0 (this represents the case where you do not buy apples).

C(0) = $2.49*0 = $0

The maximum value for x is x = 5

Replacing that value in our equation we will find the maximum possible cost:

C(5) = $2.49*5 = $12.45

Then the domain is: D : [0, 5]

The range is:             R = [$0, $12,45]

Notice that here i used the symbols [], this is because the the values in the extremes are allowed values in the domain and in the range.

The component form of the following vectors is Option A. V = (38.3, 32.1).

To find the component form of a vector given its magnitude and direction angle, we can use trigonometry.

The component form of a vector in two dimensions is represented as (x, y), where x is the horizontal component and y is the vertical component.

In this case, the magnitude of the vector is given as 50, and the direction angle θ is 50°. We can use this information to calculate the horizontal and vertical components.

The horizontal component (x) can be found using the formula x = magnitude * cos(θ), and the vertical component (y) can be found using y = magnitude * sin(θ).

Let's calculate the components:

x = 50 * cos(50°) ≈ 38.3

y = 50 * sin(50°) ≈ 32.1

Rounding the answers to the nearest tenth, we get the component form of the vector V as (38.3, 32.1).

Therefore, the correct answer is A. V = (38.3, 32.1).

Step-by-step explanation:

The line intercept y axis in (0,3), so in the generic equation y= mx + b, b must be 3. The line is also decreasing, so m must be negative

We have two options: B and D

If we try to put y=0 in these equations we have:

-1/2x + 3 = 0

Let’s solve the equation

-x + 6 = 0

x -6 = 0

x = 6

Checking the graph we notice that the line doesn’t intercept x axis in (6,0), so option B is wrong

For be sure, let’s try the same with option D

-2x + 3 = 0

-2x = -3

x = 3/2

This time is correct, so D is the right answer

Based on the fact that the vehicle's fuel efficiency is not less than 35 miles per gallon, using f to represent the vehicle's fuel efficiency gives f ≥ 35.

The fuel efficiency of the vehicle is no less than 35 miles per gallon. This means that the fuel efficiency is either 35 miles per gallon, or greater than 35 miles per gallon.

Assuming f is meant to represent this fuel efficiency of a vehicle, this means that f can be shown as being either greater than, or equal to 35 miles per gallon.
