The distance between the library and the school using the coordinates plane is 7.28 miles.

A coordinate plane is a two-dimensional plane which is formed by the intersection of two number lines - a horizontal number line called the x-axis and is a vertical number line called the y-axis. It is a graphing and description system for points and lines. On the provided coordinate plane, the coordinate of the library is (-3,3) and the coordinate of the school is (4, 1).

The distance formula between two coordinates is given by:

d =√((x2 – x1)^2 + (y2 - y1)^2)

Using the distance formula, the distance between the library and the school are:

d =√((-3 – 4)^2 + (3 - 1)^2)

d =√((-7)^2 + (2)^2)

d =√((-7)^2 + (2)^2)

d =√(49 + 4)

d =√53

d = 7.28 miles

I think the answer is 15 apples.

Answer:

16

Step-by-step explanation:

1.a. P(x < 60) = P(z < z-score) = P(z < calculated value) b) P(x > 16) = P(z > z-score) = P(z > calculated value) c) P(16 < x < 60) = P(x < 60) - P(x < 16) d) P(x > 60) = 1 - P(x < 60) 2a) we need to find the z-score that corresponds to the cumulative probability of 0.08.

1. Medical: Blood Protoplasm Porphyrin

(a) To find P(x < 60), we need to calculate the probability that the random variable x is less than 60. Since x is approximately normally distributed with a mean of 38 and standard deviation of 6-12, we can use the normal distribution to find this probability.

We can standardize the value 60 using the formula z = (x - μ) / σ, where μ is the mean and σ is the standard deviation.

Standardizing 60:

z = (60 - 38) / 6-12

Next, we can use a standard normal distribution table or a calculator to find the corresponding probability associated with the z-score. Let's assume the probability is P.

Therefore, P(x < 60) = P(z < z-score) = P(z < calculated value)

(b) To find P(x > 16), we need to calculate the probability that the random variable x is greater than 16. Similarly, we can standardize the value 16 and find the corresponding probability P.

P(x > 16) = P(z > z-score) = P(z > calculated value)

(c) To find P(16 < x < 60), we need to calculate the probability that the random variable x falls between 16 and 60. We can calculate this probability by finding the difference between P(x < 60) and P(x < 16).

P(16 < x < 60) = P(x < 60) - P(x < 16)

(d) To find P(x > 60), we need to calculate the probability that the random variable x is more than 60.

P(x > 60) = 1 - P(x < 60)

2. Basic Computation: Find z Values

(a) To find z such that 8% of the standard normal curve lies to the left of z, we need to find the z-score that corresponds to the cumulative probability of 0.08.

(b) To find z such that 9.4% of the standard normal curve lies to the left of 2, we need to find the z-score that corresponds to the cumulative probability of 0.094.

(c) To find z such that 97.5% of the standard normal curve lies to the left of z, we need to find the z-score that corresponds to the cumulative probability of 0.975.

(d) To find z such that 6% of the standard normal curve lies to the right of z, we need to find the z-score that corresponds to the cumulative probability of 0.06 (subtracting it from 1).

(e) To find z such that 72% of the standard normal curve lies to the right of z, we need to find the z-score that corresponds to the cumulative probability of 0.72 (subtracting it from 1).

(f) To find the z value such that 90% of the standard normal curve lies between -z and z, we need to find the z-score that corresponds to the cumulative probability of 0.95 (dividing 90% by 2 and adding it to 0.5 to find the area on each side).

The concept being tested is functions.

The graph describe is a vertical parabola that opens downwards.

All vertical parabolas are functions because the pass the vertical line test.

In other words, each time, t, is associated with exactly one car value, y.

The correct answer is the second option.

(a) 0 --► 0 (absorbing)

|      |

▼      ▼

1 --► 2 --► 3 --► 4 (absorbing)

(b) This chain is not irreducible.

(c) \(E(X_5 | X_3 = 1, X_0 = 2) = E(X_5 | X_2 = 2) = 9\).

(d) a = [1, 1, 7, 49, 343] satisfies all the conditions, and it is unique up to scaling by a constant factor.

(a) The graphical diagram for the random walk with absorbing barriers on {0, 1, 2, 3, 4} is as follows:

0 --► 0 (absorbing)

|      |

▼      ▼

1 --► 2 --► 3 --► 4 (absorbing)

The arrows represent the possible transitions between the states of the Markov chain, with the absorbing states shown in parentheses.

(b) This chain is not irreducible because there is no way to transition from states 0 or 4 to any other state.

(c) To find \(E(X_5 | X_3 = 1, X_0 = 2),\) we first note that \(X_3\)= 1 and \(X_0\)= 2 imply that the chain is currently in state 2. Therefore, we can condition on \(X_2\) = 2 and use the Markov property to compute the conditional expected value:

\(E(X_5 | X_3 = 1, X_0 = 2),\) \(= E(X_5 | X_2 = 2)\)

To compute this, we can use the law of total probability and conditioning on the next transition:

\(E(X_5 | X_2 = 2) = \sum j P(X_3 = j | X_2 = 2) E(X_5 | X_3 = j, X_2 = 2)\)

Since the chain is absorbing, we have E(X5 | X3 = j, X2 = 2) = 5 if j = 4, and \(E(X_5 | X_3 = j, X_2 = 2) = 1 + E(X_5)\) if j ≠ 4. Therefore, we have:

\(E(X_5 | X_2 = 2) = P(X_3 = 4 | X_2 = 2) * 5 + \sum j≠4 P(X_3 = j | X_2 = 2) * (1 + E(X_5))\)

To compute the probabilities, we can use the transition probability matrix:

\(P(X_3 = 4 | X_2\) = 2) = P(4 | 2) = 1

\(P(X_3 = j | X_2\)= 2) = P(j | 2) = 0 for j ≠ 1, 3

Therefore, we have:

\(E(X_5 | X_2\)= 2) = 5 + 0.5 * (1 + E(\(X_5\)))

Solving for E(\(X_5\)), we get:

E(\(X_5\)) = 9

Therefore, E(\(X_5\) | \(X_3\) = 1, \(X_0\) = 2) = E(\(X_5\)| \(X_2\) = 2) = 9.

(d) To find a row vector a such that all coordinates are nonnegative and sum to one, and TP = 7a, we can use the fact that a is a left eigenvector of P with eigenvalue 7. That is, we have aP = 7a. Writing out the equations, we get:

Since the sum of the coordinates of a is one, we can choose any nonzero value for a₀ and normalize the vector accordingly. For simplicity, we can choose a₀ = 1, giving:

Therefore, a = [1, 1, 7, 49, 343] satisfies all the conditions, and it is unique up to scaling by a constant factor.

The total debt-equity ratio is 0. 50. The correct answer is B.

A company's debt-to-equity ratio (D/E ratio) reveals how much debt it has in relation to its assets. It is calculated by dividing the total debt of a corporation by the total shareholder equity.

To calculate the total debt-equity ratio, we divide the total debt by the total equity.

Total equity = $183,000

Total assets = $275,000

Total debt = Total assets - Total equity

Total debt = $275,000 - $183,000

Total debt = $92,000

Debt-Equity Ratio = Total debt / Total equity

Debt-Equity Ratio = $92,000 / $183,000

Debt-Equity Ratio ≈ 0.5027

Rounding to two decimal places, the total debt-equity ratio is approximately 0.50.

The bride and groom can form 252 different groups of five people from the total of 10 people at the rehearsal dinner, as they need to assign them to two tables of five people each.

To determine the number of different groups of five people that can be formed, we can use the concept of combinations. In this scenario, we have 10 people who need to be divided into two groups of five people each.

The number of ways to choose five people out of 10 can be calculated using the combination formula. The formula for combinations is given by:

C(n, r) = n! / (r! * (n - r)!)

Where n represents the total number of people and r represents the number of people to be chosen. In this case, n = 10 and r = 5.

Plugging these values into the formula, we get:

C(10, 5) = 10! / (5! * (10 - 5)!)

= (10 * 9 * 8 * 7 * 6 * 5!) / (5! * 5 * 4 * 3 * 2 * 1)

= (10 * 9 * 8 * 7 * 6) / (5 * 4 * 3 * 2 * 1)

= 252

Therefore, the bride and groom can form 252 different groups of five people from the total of 10 people at the rehearsal dinner. This means that there are 252 distinct ways to divide the 10 people into two tables of five people each, providing flexibility in creating diverse groups for the dinner.

A line segment can be defined as the part of a line in a geometric figure such as a triangle, circle, quadrilateral, etc., that is bounded by two (2) distinct points and it typically has a fixed length.

A translation can be defined as a type of transformation which moves every point of the object in the same direction, as well as for the same distance.

Answer:

How many balls have “R” written on them initially? We can see this is 2.

How many balls are there initially? This is 9.

As a result, the probability of initially drawing a ball with an R on it is 2/9, as out of the 9 possible draws we could make, 2 of them result in a ball with R on it.

How many balls have “R” written on them now? We can see this is 1, since we just drew one ball with R on it and didn’t replace.

How many balls are there in total right now? This is 8, because we took away one.

As a result, the probability of drawing a ball with an R on it after having already done so is 1/8, as out of the 8 possible draws we could make, 1 results in a ball with R on it.

We then multiply these two values (2/9)*(1/8) = 2/72, which is our probability.

Another way to think about this is that there are 72 possible combinations of balls that we could draw, counting each ball uniquely. This is because of our denominator, since 8*9=72. Out of those 72 outcomes that could possibly happen, 2 outcomes will result in both balls being written with R.

To get a probability of 3/5, 16 red marbles must be added.

There are 8 red, 9 yellow, and 7 green marbles, for a total of:

8 + 9 + 7 = 24.

The probability of getting a particular color of marble is given by the quotient between the number of marbles of that color and the total number of marbles.

Here, we want to get a probability of drawing a red marble equal to 3/5.

So, if we add x red marbles, the probability of getting a red marble will be:

P = (8 + x)/(24 + x)

And that must be equal ot 1/5, then we write:

(3/5) = (8 + x)/(24 + x)

If we multiply both sides bt (24 + x), we will get:

3*(24 + x)/5 = 8 + x

Now we can solve that for x.

3*24/5 - 8 = x - x(3/5) = (2/5)*x

x = (3*24/5)*(5/2) - (5/2)*8 = 16

Answer:

Step-by-step explanation:

To determine if two functions are inverses of each other, we need to check if their compositions result in the identity function.

Let's examine each pair of functions:

A. f(x) = 3(3) - 10 and g(x) = -8

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

f(g(x)) = 3(-8) - 10 = -34

Since f(g(x)) ≠ x, these functions are not inverses of each other.

B. f(x) = x + 8 + 9 and g(x) = 4(x + 8) - 9

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

f(g(x)) = 4(x + 8) - 9 + 8 + 9 = 4x + 32

Since f(g(x)) ≠ x, these functions are not inverses of each other.

C. f(x) = 4(x - 12) + 2 and g(x) = x + 12 - 2

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

f(g(x)) = 4((x + 12) - 2) + 2 = 4x + 44

Since f(g(x)) ≠ x, these functions are not inverses of each other.

D. f(x) = 3 - 4 and g(x) = 2(x + 4)

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

f(g(x)) = 3 - 4 = -1

Since f(g(x)) = x, these functions are inverses of each other.

Therefore, the pair of functions f(x) = 3 - 4 and g(x) = 2(x + 4) are inverses of each other.

x + (2x + 1) + (x/2 - 13) + 45 + (x + 22) = 83 × 5

x + 2x + 1 + x/2 - 13 + 45 + x + 22 = 415

(x + 2x + x/2) + (1 - 13 + 45 + 22) = 415

Step-by-step explanation:

     To solve, we will isolate the p variable.

Given:

     -3p + 6.7 > -4.4

Subtract 6.7 from both sides of the equation:

     -3p > -11.1

Divide both sides of the equation by 3:

Note, you must switch the sign since you're dividing by a negative.

     p < \(-\frac{11.1}{3}\)

Answer:

p < 3.7

Step-by-step explanation:

-3p + 6.7 > -4.4

1- subtract 6.7 to leave -3p alone

-3p + 6.7 -6.7 > -4.4 - 6.7

-3p > -11.1

2- Divide both sides by -3. NOTE; u must change the > sign to < because u r dividing by a negative

-3p/-3 = p

-11.1/-3= 3.7

p < 3.7

The response variable, brain connectivity, was measured using an MRI machine. The researchers found a "Goldilocks effect" in the brain connectivity, indicating that the audio format was associated with low brain connectivity, possibly due to the children straining to understand.

On the other hand, the animated format also resulted in low brain connectivity, suggesting that the animation did all the work for the children.

The highest brain connectivity, considered optimal, was observed with the illustrated format, which simulated the experience of reading a book to a child.
