Answer:

  about 57.1 persons per square mile

Step-by-step explanation:

To find persons per square mile, divide persons by square miles:

  (200 million persons)/(3.5 million mi^2) = (200/3.5) persons/mi^2

  ≈ 57.1 persons/mi^2

Answer:

1 foot = 0.3048 meters

Step-by-step explanation:

1 foot = 12 inches

1 inch = 2.54 centimeters

1 foot = 12 * 2.54 = 30.48 centimeters

1 meter = 0.01 centimeters

1 foot = 0.3048 meters

Answer:

numerator =  

✔ 0.3048 meters

denominator =  

✔ 1 foot

Answer:

38 and 52

Step-by-step explanation:

x = small angle

Complementary angles add to 90 degrees

x + x+14 = 90

2x = 76

x= 38

90-38 = 52

52-14 = 38

38 +52 = 90

Answer:

y = 5- 36

Step-by-step explanation:

6 is the x

-6 is the y

y=mx+b

so m times x, m is the slope

5 times 6 is 30

-6=30+b

so -36

y=5x-36

Greatest Common Factor: 24

Step-by-step explanation:

The greatest common factor is found by multiplying all the factors which appear in both lists: So the GCF of 24 (2x2x2x3) and 48 (2x2x2x2x3) is 2x2x2x3 which is 24.

The greatest common factor of 24 and 48 is 24.

Here, we have,

To find the greatest common factor (GCF) of 24 and 48,

we can use the prime factorization method:

Step 1: Find the prime factorization of each number.

Prime factorization of 24:

24 = 2 * 2 * 2 * 3

Prime factorization of 48:

48 = 2 * 2 * 2 * 2 * 3

Step 2: Identify the common prime factors and their lowest exponents.

Common prime factors: 2 * 2 * 2 * 3

Step 3: Multiply the common prime factors with their lowest exponents.

GCF(24, 48) = 2 * 2 * 2 * 3 = 24

So, the greatest common factor of 24 and 48 is 24.

Answer: answer is -7

Step-by-step explanation:

Step-by-step explanation:

Original Equation;

1x=7(x+6)

Multiply the 7 by the x and 6

1x=7x+42

Group like terms

1x-7x=42

-6x=42(Divide both sides by -6)

x= -7 (We have -7 because 42 can be divided by 6 7 times)

Answer:

C.

Step-by-step explanation:

Answer:

42

Step-by-step explanation:

If the decimal was 5 or higher, that means it would've been 43, but since it's lower than 4, it rounds down to 42.

Answer:

$2754.70

Step-by-step explanation:

Answer:

(a) 0.2061

(b) 0.2514

(c) 0

Step-by-step explanation:

Let X denote the heights of women in the USA.

It is provided that X follows a normal distribution with a mean of 64 inches and a standard deviation of 3 inches.

(a)

Compute the probability that the sample mean is greater than 63 inches as follows:

[tex]P(\bar X>63)=P(\frac{\bar X-\mu}{\sigma/\sqrt{n}}>\frac{63-64}{3/\sqrt{6}})\\\\=P(Z>-0.82)\\\\=P(Z<0.82)\\\\=0.20611\\\\\approx 0.2061[/tex]

Thus, the probability that the sample mean is greater than 63 inches is 0.2061.

(b)

Compute the probability that a randomly selected woman is taller than 66 inches as follows:

[tex]P(X>66)=P(\frac{X-\mu}{\sigma}>\frac{66-64}{3})\\\\=P(Z>0.67)\\\\=1-P(Z<0.67)\\\\=1-0.74857\\\\=0.25143\\\\\approx 0.2514[/tex]

Thus, the probability that a randomly selected woman is taller than 66 inches is 0.2514.

(c)

Compute the probability that the mean height of a random sample of 100 women is greater than 66 inches as follows:

[tex]P(\bar X>66)=P(\frac{\bar X-\mu}{\sigma/\sqrt{n}}>\frac{66-64}{3/\sqrt{100}})\\\\=P(Z>6.67)\\\\\ =0[/tex]

Thus, the probability that the mean height of a random sample of 100 women is greater than 66 inches is 0.

The part of the solution of the equation that lies in the solution region of the inequality is x = π/6, the correct option is A.

An Inequality is a statement that is formed when two expressions are joined using an inequality operator.

The equation is

y = tan²x

y = 1

the inequalities are

tan²x < 1   ( 0≤ x ≤ 2π)

The graph of the system of equations and the inequality is plotted, and attached with the answer.

The answer can be seen as  x = π/6.

We want to compare the population equations for two given states.

The correct option is:

"The original population of State A was double of the original population of State B"

We know that the population of state A is given by:

f(x) = 4*(1.08)^x

While for state B, the population is given by:

g(x) = 2*(1.08)^x

We want to see which conclusion is correct about the population of state A and state B.

First, the general exponential growth equation is given by:

h(x) = A*(r)^x

Where A is the initial value and r is the rate of growth.

With this, we can see that f(x) and g(x) have the same rate, and f(x) has an initial value that is twice the one of g(x).

Then the correct option is "The original population of State A was double of the original population of State B"

Because the initial value represents the initial population.
