They are not the best factors to use because 12 cannot be simplified further into a perfect square. It is better to factor 48 into perfect squares and simplify each square root separately.

Factors can be classified as prime or composite. A prime factor is a factor that is a prime number, meaning it is only divisible by 1 and itself. For example, the prime factors of 12 are 2 and 3. A composite factor is a factor that is not a prime number, meaning it has more than two factors. For example, 4, 6, and 12 are composite factors of 12.

Let's examine the factors 4 and 12 to see if they can be used to simplify the square root of 48:

4 is a perfect square, and its square root is 2. However, 12 is not a perfect square, and its square root cannot be simplified further.

We can write 48 as 4 x 12, so the square root of 48 can be simplified as the product of the square root of 4 and the square root of 12, or 2√12.

However, this is not the simplest form of the square root of 48. We can further simplify √12 by factoring it into perfect squares: √12 = √(4 x 3) = √4 x √3 = 2√3.

Therefore, the simplest form of the square root of 48 is 2√3, not 2√12.

The correct answer is C. It is significant at the 5% level.

To determine the statistical significance of the slope coefficient, we need to calculate the t-statistic for the slope coefficient and compare it to the critical value for the desired level of significance.

The t-statistic is calculated as:

t = (slope coefficient - hypothesized value) / standard error of the slope coefficient

In this case, the hypothesized value is 0 (no relationship between x and y) and the standard error of the slope coefficient is 0.43. So the t-statistic is:

t = (0.78 - 0) / 0.43 = 1.81

Now we need to compare this t-statistic to the critical value for the desired level of significance. For a two-tailed test with 202 - 2 = 200 degrees of freedom, the critical values are:

- 1.645 for the 10% level
- 1.96 for the 5% level
- 2.576 for the 1% level

Since the t-statistic (1.81) is greater than the critical value for the 10% level (1.645) but less than the critical value for the 5% level (1.96), we can conclude that the slope coefficient is significant at the 10% level but not at the 5% level. Therefore, the correct answer is B. It is significant at the 10% level.

A(t) = $3,600(1.125)t is the function that displays the balance of the account after t years, rounded to four decimal places.

The definition of the word "invest" is to "expend money with the idea of attaining a profit or material consequence by putting it into financial plans, etc." A person is "vested" when they are "secured in their possession or allocated to a person," on the other hand. It can also imply outfitted with a vest, although that is unimportant just now.

A(t) = P(1 + r)t

where:

A(t) represents the balance of the account after t years.

P is the initial investment, $3,600, and r is the growth rate per year.

The number of years is t.

A(t) = $3,600(1 + 0.125)t

A(t) = $3,600(1.125)t

We can take the growth rate and subtract 1 to get the annual growth percentage, which we can then translate to a percentage as follows:

Percentage growth rate = (1.125 - 1) * 100% = 12.5%

So the account grows by approximately 12.5% per year.

(x - 6)(3x + 15) + 95

Step-by-step explanation:

Here's the long division of (3x^2 - 3x + 5) ÷ (x - 6):

   3x + 15

 --------------

x - 6 | 3x^2 - 3x + 5

- (3x^2 - 18x)

--------------

15x + 5

- (15x - 90)

------------

95

Therefore, the quotient is 3x + 15, and the remainder is 95.

The quotient represents the result of the division of the polynomial (3x^2 - 3x + 5) by the divisor (x - 6). In particular, the quotient 3x + 15 represents the linear polynomial that, when multiplied by the divisor x - 6, gives the dividend 3x^2 - 3x + 5.

In other words, we have:

(3x^2 - 3x + 5) = (x - 6)(3x + 15) + 95

The remainder 95 indicates that the division is not exact, and that there is a "leftover" term of 95 when we try to divide the polynomial (3x^2 - 3x + 5) by (x - 6).

Answer:

See explanation below

Step-by-step explanation:

S has x-coordinate of 6 => the distance from origin to x-coordinate is 6 units, which is one leg of the right triangle

Pythagorean theorem states that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.

c^2 = a^2 + b^2

with c = 10, a = 6

10^2 = 6^2 + b^2

b^2 = 100 - 36 = 64

b = √64 = 8

Point S can have 2 y-coordinates, one (+) and one (-) depending on the location of point S, so S can be either (6,8) or (6,-8)

Answer:

187

Step-by-step explanation:

I personally just do multiplication whenever I can, but that's just me. Like for example I know 100 x 3 = 300 and 200 x 3 = 600. SO it has to be between 100 and 200.

150 x 3 = 450. So know it narrows it down to between 150 and 200.

175 x 3 = 525

180 x 3 = 540

185 x 3 = 555

190 x 3 =570

So now it's between 185 and 190.

Now I just need to do the following.

186 x 3 = 558

187 x 3 = 561

And there we have the answer.

To find the ground distance traveled by the aircraft, we can use the trigonometric function tangent. The tangent of an angle in a right triangle is equal to the opposite side divided by the adjacent side. In this case, the opposite side is the height of the aircraft (30,000 ft) and the adjacent side is the ground distance traveled (x).
Therefore, we can set up the following equation:
tan10° = 30,000/x

We are given that tan10° = 0.176, so we can substitute that value into the equation:
0.176 = 30,000/x
Next, we can cross-multiply and solve for x:
x = 30,000/0.176
x ≈ 170,455 ft
Finally, we can convert the ground distance traveled from feet to nautical miles using the conversion factor 1 Nm = 6076 ft:
170,455 ft * (1 Nm/6076 ft) ≈ 28.06 Nm
Therefore, the ground distance traveled by the aircraft is approximately 28.06 nautical miles.

Simplified each expression of  (x²-25x-24)/(6x+2x²)*(5x²)/(8-x) is (-5x(x-24)(x-1))/(2(3+x)(x-8)).

To simplify the expression (x²-25x-24)/(6x+2x²)*(5x²)/(8-x), we need to factor the polynomials in the numerator and denominator and then cancel out any common factors.

First, let's factor the polynomials:

(x²-25x-24) = (x-24)(x-1)
(6x+2x²) = 2x(3+x)
(5x²) = 5x*x
(8-x) = -(x-8)

Now, let's plug these back into the expression and cancel out any common factors:

((x-24)(x-1))/(2x(3+x))*(5x*x)/(-(x-8))

= ((x-24)(x-1)*5x*x)/(2x(3+x)*-(x-8))

= ((x-24)(x-1)*5x)/(2(3+x)*-(x-8))

= (5x(x-24)(x-1))/(-2(3+x)(x-8))

Finally, let's simplify the expression by multiplying the constants:

= (-5x(x-24)(x-1))/(2(3+x)(x-8))

So the simplified expression is (-5x(x-24)(x-1))/(2(3+x)(x-8)).

Using Poisson distribution, the probability of each scenario is attached below.

(a) The probability of receiving 0 complaints in a 3-day period is given by the Poisson distribution:

P(X=0) = (λ^x * e^(-λ)) / x!

where λ is the expected number of complaints per day, and x is the number of complaints in the time period of interest.

In this case, λ = 1.1 complaints per day, and x = 0 complaints in 3 days.

P(X=0) = (1.1^0 * e^(-1.1 * 3)) / 0! = 0.037

So the probability of receiving 0 complaints in a 3-day period is 3.7%.

(b) The probability of receiving 1 complaint in a 3-day period is:

P(X=1) = (1.1^1 * e^(-1.1 * 3)) / 1! = 0.041

So the probability of receiving 1 complaint in a 3-day period is 4.1%.

(c) The probability of receiving 2 complaints in a 3-day period is:

P(X=2) = (1.1^2 * e^(-1.1 * 3)) / 2! = 0.022

So the probability of receiving 2 complaints in a 3-day period is 2.2%.

(d) The probability of receiving 3 complaints in a 3-day period is:

P(X=3) = (1.1^3 * e^(-1.1 * 3)) / 3! = 0.008

So the probability of receiving 3 complaints in a 3-day period is 0.8%.

(e) The probability of receiving 4 complaints in a 3-day period is:

P(X=4) = (1.1^4 * e^(-1.1 * 3)) / 4! = 0.0022

So the probability of receiving 4 complaints in a 3-day period is 0.22%.

(f) The probability of receiving less than or equal to 4 complaints in a 3-day period is:

P(X ≤ 4) = P(X=0) + P(X=1) + P(X=2) + P(X=3) + P(X=4) = 0.1102

So the probability of receiving less than or equal to 4 complaints in a 3-day period is 11.02%.

(g) The probability of receiving more than 4 complaints in a 3-day period is:

P(X > 4) = 1 - P(X ≤ 4) = 1 - 0.1102 = 0.8898

So the probability of receiving more than 4 complaints in a 3-day period is 88.98%.
