Answer:

about 1854.55 miles (rounded to the hundredth)

Step-by-step explanation:

1.

\( \frac{44}{100} = \frac{816}{x} \)

The first fraction represent the percentage of the distance.

The second one represent the number of 816 miles out of x

2. 100 × 816 = 44 × x

3. You'll get 81,600 = 44x

4. and then you divided both side by 44 to solve for x

Step-by-step explanation:

Start with Jose's initial balance.

\(178.74\)

He wrote checks, so we have to subtract the total amount the checks were worth. Let's first add the three amounts.

\(36.52+18.92+25.93\)

Solve.

\(81.37\)

Subtract the total amount of the checks from Jose's initial balance.

\(178.74-81.37\)

Solve.

\(97.37\)

The amount above is now what is in Jose's checking account.

But, he also deposited money, meaning he put money in his checking account. Now, let's add the three amounts he deposited.

\(300.00+100.00+205.16\)

Solve.

\(605.16\)

The amount above is what Jose adds to his checking out.

Add the total value of the deposited money and his new balance.

\(605.16+97.37\)

Solve.

\(605.16+97.37=702.53\)

The cost function C(x) = 5x + 6,000/x, where x is the length of one of the sides of the rectangular area, gives the cost of building the fence. The dimension of the least expensive fence is x = 60ft, and the minimum cost is $500.

Let's assume the length of one of the sides of the rectangular area is x feet. Since the area is 3,000ft², the width of the rectangle can be expressed as 3000/x feet.

The cost of building the fence consists of the cost for the two sides facing north and south, which is $2.50 per foot, and the cost for the other two sides, which is $3.00 per foot. Therefore, the cost function C(x) can be calculated as follows:

C(x) = 2(2.50x) + 2(3.00(3000/x))

     = 5x + 6000/x

To find the dimension of the least expensive fence, we can take the derivative of the cost function C(x) with respect to x and set it equal to zero:

C'(x) = 5 - 6000/x² = 0

Solving this equation, we get x² = 6000/5, which simplifies to x = √(6000/5) = 60ft.

Therefore, the dimension of the least expensive fence is x = 60ft. Substituting this value back into the cost function, we find the minimum cost:

C(60) = 5(60) + 6000/60

      = 300 + 100

      = $500

Hence, the minimum cost of the fence is $500.

The given information mentions the sample mean and sample standard deviation of San Francisco student scores on the most recent Scholastic Aptitude Test (SAT) examination in mathematics.

To fully interpret the given information, we would need the numerical values of the sample mean and sample standard deviation. The sample mean represents the average score of the students on the SAT math examination, while the sample standard deviation measures the variability or spread of the scores around the mean.

These statistics provide valuable insights into the performance of San Francisco students on the SAT math examination. The sample mean gives an indication of the typical score achieved by the students, while the sample standard deviation helps assess the dispersion or diversity of scores. A higher standard deviation suggests a wider range of scores, indicating greater variability among the students' performance. Conversely, a lower standard deviation suggests more consistency in scores.

Without the specific values of the sample mean and sample standard deviation, we cannot provide further analysis or interpretation of the data.

The ant population will reach 38.2 thousand in about 3.25 years, assuming a growth rate of 5% per year.

To answer this question, we need to know the growth rate of the ant population. Let's say the growth rate is 5% per year. This means that each year, the population will increase by 5% of its current size. To calculate the population size after a certain number of years, we can use the formula:

P = P0 * (1 + r)^t

where P is the population size after t years, P0 is the initial population size, r is the growth rate as a decimal, and t is the number of years.

Assuming the initial population size is 30 thousand, we can plug in the values to find when the population will reach 38.2 thousand:

38.2 = 30 * (1 + 0.05)^t

Solving for t, we get t = 3.25 years. However, it's important to note that the actual growth rate may be different, so this calculation is just an estimate.

We cannot provide a value for k as requested in the question. Hence, our answer is: No, we cannot determine whether the function f is a k-to-1 correspondence for some positive integer k without having the function f.

justify your answer," we need to first understand what a k-to-1 correspondence is.

A k-to-1 correspondence is a function in which each element in the range has exactly k preimages. In other words, if the function f maps elements from set A to set B, then for each element b in set B, there are exactly k elements in set A that map to b.

In this case, we need to determine if the function f is a k-to-1 correspondence for some positive integer k.Now, let's justify our answer. Since we do not have the function f, we cannot determine whether it is a k-to-1 correspondence or not. Therefore, we cannot provide a value for k as requested in the question. Hence, our answer is: No, we cannot determine whether the function f is a k-to-1 correspondence for some positive integer k without having the function f.

The equation is;

f(x) = -2·x² + 5·x - 1

Step-by-step explanation:

The general form of a quadratic equation  or function f(x) is, f(x) = y = a·x² + b·x + c

Given that the points representing the quadratic function are;

(-1, -8), (0, -1), (1, 2) which  are of the form (x, y)

When x = -1, f(x) = y = -8

Plugging in the above values into the general form of a quadratic function, we have;

-8 = a·(-1)² + b·(-1) + c = a - b + c

-8  = a - b + c.........................(1)

When x = 0, y = -1, we have;

-1 = a·(0)² + b·(0) + c = c

c = -1.......................................(2)

When x = 1, y = 2, which gives;

2 = a·(1)² + b·(1) + c = a + b + c

2 = a + b + c........................(3)

Adding equation (1) to equation (3), we have;

-8 + 2 = a - b + c + a + b + c

-8 + 2 = 2·a + 2·c

From equation (2) c = -1, we get;

-8 + 2 = -6 = 2·a + 2·c = 2·a + 2 × (-1)

-6 = 2·a - 2

-4 = 2·a

a = -2

From equation (3), we have

2 = a + b + c

Substituting the values of a, and c gives;

2 = -2 + b - 1

b = 2 + 2 + 1 = 5

b = 5

The equation is therefore;

f(x) = -2·x² + 5·x - 1.

The initial population of the bacteria culture is 200 bacteria.

The initial population of the bacteria culture can be determined using the equation for exponential growth: P(t)=P0(1+rt), where P(t) is the population after time t, P0 is the initial population, and r is the relative growth rate.

In this case, after 2 hours, the population is 600 and after 8 hours the population is 75,000. Plugging in the values, we get P0 = 600/(1+2*r), or P0 = 600/3. Thus, the initial population of the bacteria culture is 600/3 = 200 bacteria.

Exponential growth is a function of time and rate of growth. It is often used to model population growth or decay, such as in this case. The equation for exponential growth states that the population at any time is equal to the initial population multiplied by the rate of growth at each unit of time.

In this case, the rate of growth (r) is constant over the time period, so the population can be determined by putting in the values for P(t) and P0 and solving for r. Then, using the same equation, the initial population (P0) can be determined.

Answer:

Step-by-step explanation:

The Pythagorean theorem states that for a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). Using this formula, we can solve for the length of the missing side:

c^2 = a^2 + b^2

26^2 = 10^2 + b^2

676 = 100 + b^2

b^2 = 576

b = sqrt(576)

b = 24

Therefore, the length of side b is 24 units.

\(\begin{array}{llll} \textit{using the pythagorean theorem} \\\\ a^2+o^2=c^2\implies o=\sqrt{c^2 - a^2} \end{array} \qquad \begin{cases} c=\stackrel{hypotenuse}{26}\\ a=\stackrel{adjacent}{10}\\ o=\stackrel{opposite}{b} \end{cases} \\\\\\ b=\sqrt{ 26^2 - 10^2}\implies b=\sqrt{ 676 - 100 } \implies b=\sqrt{ 576 }\implies b=24\)

There are 2 solutions to square root x = 9

They are 3, and -3

Step-by-step explanation:

The square root of x=9 has 2 solutions,

The square root means, for a given number, (in our case 9) what number times itself equals the given number,

Or, squaring (i.e multiplying with itself) what number would give the given number,

so, we have to find the solutions to \(\sqrt{9}\)

since we know that,

\((3)(3) = 9\\and,\\(-3)(-3) = 9\)

hence if we square either 3 or -3, we get 9

Hence the solutions are 3, and -3

Answer:

5 weeks

Step-by-step explanation:

Let's find how much money she saves a week by multiplying the decimal form of 60% and $70.

To get the decimal form of a percent you have to move the decimal to the left twice, like this: 60 ---> .60

Now that we have the decimal form of the percent we can multiply it by the 70 to find how much she saves a week:(70)(.6) = 42

Therefore, Kendra saves $42 each week. To find how many weeks it will take Kendra to buy the game system you divide $210 by the $42.

Like this:(210)/(42) = 5 All in all, it will take Kendra 5 weeks to save enough money to buy a game system that costs $210. I hope this helps!!

To calculate the standard deviation of the returns on this stock, we first need to find the expected return and then calculate the variance before taking the square root.

Given the probabilities and returns for each economic state, let's compute the expected return:

Expected return = (Boom return × Probability of boom) + (Normal return × Probability of normal) + (Recession return × Probability of recession)

Since the probabilities of boom and recession are given as 20% and 25% respectively, the probability of a normal economy is 100% - (20% + 25%) = 55%.

Expected return = (0.32 × 0.2) + (0.14 × 0.55) + (-0.28 × 0.25) = 0.064 + 0.077 + (-0.07) = 0.071

Next, we calculate the variance:

Variance = Σ [Probability(i) × (Return(i) - Expected return)²]

Variance = (0.2 × (0.32 - 0.071)²) + (0.55 × (0.14 - 0.071)²) + (0.25 × (-0.28 - 0.071)²) = 0.049401 + 0.002555 + 0.045956 = 0.097912

Finally, we find the standard deviation by taking the square root of the variance: Standard deviation = √(0.097912) ≈ 0.313, The standard deviation of the returns on this stock is approximately 0.313, or 31.3%.
