how many square miles does ATC and radar services attempt to cover? How many aircraft at any given time is ATC monitoring, and spread over how many airports within the USA?

9A:

The problem says 35% of the 3560 applications are from boys who lived in other states.

This can be expressed as:

3560*35% = 3560*0.35 = 1246 applications.

9B:

The problem says applications to the university (3560 applications) represented 40% of all applications.

This can be expressed as:

3560 = 40% * A, where A = number of applications received in all.

To find how many applications received in all, just solve for A.

A = 3560 / 0.4 = 8900 applications.

The key to these types of problems is that "of" signals multiplication. For example, 40% of all applications is 40% * all applications.

Answer:

8 Hours

Step-by-step explanation:

We know she travels 220 miles in 5 hours, so lets create an equation with a ratio which finds the miles she drives in a single hour, multiply that by x, and then set it equal to 352.

\(\frac{220}{5}x=352\)

Multiply both sides by 5

\(220x=1760\)

Divide both sides by 220

\(x=8\)

Therefore it would take 8 hours.

8 Hours long would it take to travel 352 miles,

The distance that an object travels in relation to the amount of time it takes to do so can be used to define speed. In other words, it is a measurement of an object's motion's speed without direction Velocities are what we get when speed and direction are combined. The SI unit system is most frequently used to express speed units. In that system, since distance is measured in metres and time is measured in seconds, speed is expressed in metres per second, or m/s. Three components make up the speed formula: distance, time, and speed.

We know she travels 220 miles in 5 hours, so lets create an equation with a ratio which finds the miles she drives in a single hour, multiply that by x, and then set it equal to 352.

Multiply both sides by 5

Divide both sides by 220

Hence, it would take 8 hours.

The expression which represents the amount of money Chloe owes is

amount = 14c - 3c. where 'c' is the cost per box.

What is a linear equation in one variable?

A linear equation is a one-variable equation of a straight line. The variable's only power is 1. Linear equations in one variable with the form an x + b = 0 are solved using basic algebraic operations.

Chloe ordered 14 boxes and per box 'c' dollars charged

Hence the total amount of money she has to pay is $14c

But 3 of the boxes are damaged so their price will be deducted from the total amount she was supposed to pay:

Now equation will become,

amount = 14c - 3c.

Hence, the expression which represents the amount of money Chloe owes is

amount = 14c - 3c. where 'c' is the cost per box.

The given statement "In order for a matrix B to be the inverse of A, the equations AB = I and BA = I must both be true." is true because of the definition of the inverse matrix.

An inverse matrix is obtained by dividing the adjugate of the given matrix by the determinant of the given matrix.

An inverse matrix is also known as a reciprocal matrix.

In order for a matrix B to be the inverse of A, both equations AB = I (Identity matrix) and BA = I must be true.

This is because the inverse of a matrix A, denoted as A⁻¹ (in this case, matrix B), should satisfy these conditions for it to be a true inverse.

When a matrix is multiplied by its inverse, the result is the identity matrix.

Step-by-step explanation:

To calculate the minimum number of days required to finish this project, we need to use the critical path method (CPM), which involves identifying the longest sequence of dependent tasks and their durations.

First, we need to draw the network diagram for the project:

```

|---(T1-8)---(T3-10)---|

(T2-6) (T5-12)

| / |

|---(T4-7)---(T6-15)---|

```

Next, we need to calculate the earliest start time (EST), earliest finish time (EFT), latest start time (LST), and latest finish time (LFT) for each task. For the starting task, EST = 0 and EFT = 0.

```

EST EFT LST LFT

T1 (8 days) 0 8 22 30

T2 (6 days) 0 6 6 12

T3 (10 days) 8 18 22 32

T4 (7 days) 18 25 25 32

T5 (12 days) 18 30 32 44

T6 (15 days) 32 47 32 47

```

The critical path is the longest sequence of dependent tasks that have no slack (i.e., the difference between LST and EST, or LFT and EFT, is zero). In this case, the critical path is T1-T3-T5-T6.

Therefore, the minimum number of days to finish this project is the sum of the durations of tasks on the critical path:

8 + 10 + 12 + 15 = 45 days

Therefore, the minimum number of days required to finish this project is 45 days.

Answer:

Step-by-step explanation:

The strength of a linear relationship between two variables is typically measured by the correlation coefficient (r) or the coefficient of determination (r^2). A value of r or r^2 closer to 1 indicates a stronger positive linear relationship, whereas a value closer to -1 indicates a stronger negative linear relationship. A value of r or r^2 closer to 0 indicates a weaker or no linear relationship.

Looking at the given regression equations and their correlation coefficients, the regression with the weakest linear relationship between x and y is Regression 3:

Regression 1: y = -5.8x - 6.5, r = -0.7621

Regression 2: y = 2.4x - 14.7, r = 0.809

Regression 3: y = -7.4x - 17.4, r = -0.233

Regression 4: y = -3.4x - 8.5, r = -0.6121

Regression 3 has the lowest absolute value of r (0.233), indicating the weakest or no linear relationship between x and y. Therefore, Regression 3 represents the weakest linear relationship between x and y among the given options.

The calculations provided yield the following results: [A] 1.77 x \(10^3\), [B] 68.022, and [C] 44.500.

[A] To solve (4.733x\(10^{-3}\)) * (6.43x\(10^5\)) / \((2.300x10^2)^2,\) we perform the operations following the order of operations (PEMDAS/BODMAS). First, we calculate the value inside the parentheses: \((2.300x10^2)^2\) = 2.300x\(10^2\) * 2.300x\(10^2\) = 5.290x\(10^4\). Then, we substitute the values and perform the remaining calculations: (4.733x\(10^{-3}\)) * (6.43x\(10^5\)) / 5.290x\(10^4\)= 3.029x\(10^3\) / 5.290x\(10^4\)= 5.722x\(10^{-2}\). Since the problem asks for the answer in significant figures, we need to round the result. The value 5.722x\(10^{-2}\) rounded to three significant figures is 1.77x\(10^3\).

[B] In the expression 62.400 + 17.222 - 11.6, we perform the addition and subtraction operations in order from left to right: 62.400 + 17.222 = 79.622, and then subtracting 11.6 from 79.622 gives us the result 68.022.

[C] To round 44.5 to the nearest thousandth, we look at the digit in the thousandths place (the third decimal place). Since the digit is 5, we round up the previous digit. Therefore, 44.5 rounded to the nearest thousandth is 44.500.

Answer:

b = 15h

Step-by-step explanation:

15/1 = 15 bikes in 1 hour.

When it turns 2 hours, it will have 30 bikes produced.

30/2 = 30 bikes in 2 hours.

15/1 is 15 and 30/2 is 15.

15/1 = 30/2

This means it is proportional.

b = 15h

b = represents bicycle

h = represents hours

Let's put in h as 2, as in 2 hours. The b should come out as 30, since 30 bicycles are made in 2 hours.

15h = b

b = 15(2)

b = 30

b does equal 30. And so this equation works for this word problem.
