The probability that it is not raining if the flight leaves on time is 0.9.

Let's define the events:

A: It is raining

B: The flight is delayed

We have,

P(A) = 0.19 (probability that it will rain)

P(B) = 0.1 (probability that the flight will be delayed)

P(A ∩ B) = 0.07 (probability that it will rain and the flight will be delayed)

Using the formula for conditional probability, we have:

P(A' | B') = P(A' ∩ B') / P(B')

Since A' and B' are complementary events (if it's not raining, then the flight is leaving on time), we can rewrite the formula as:

P(A' | B') = P(B' | A') x P(A') / P(B')

We know that P(A) + P(A') = 1, so P(A') = 1 - P(A).

Now, let's substitute the given values into the formula:

P(A' | B') = (P(B' | A') x (1 - P(A))) / P(B')

P(B' | A') represents the probability that the flight is leaving on time given that it's not raining.

We know that:

P(B') = 1 - P(B) = 1 - 0.1 = 0.9

we can estimate P(B' | A') as:

P(B' | A') ≈ P(B') = 0.9

Now we can substitute the values into the formula:

P(A' | B') ≈ (0.9 x (1 - 0.19)) / 0.9

P(A' | B') ≈ 0.81 / 0.9

P(A' | B') ≈ 0.9

Therefore, the probability that it is not raining if the flight leaves on time is 0.9.

Concluding, there are (2 + 12) boxes of pencils left.

We know that Ms. Bloom had (4 + 7/12) boxes of pencils, and we also know that (2 + 1/12) of the boxes were broken.

The number of boxes of pencils left is given by the difference between the two above numbers, then we get:

N = (4 + 7/12) - (2 + 1/12) = (4 - 2) + (7/12 - 1/12) = 2 + 6/12

Now we can simplify the fraction:

N = 2 + 1/2

Answer:

-2/2 = -1/1 = -1

The function with an amplitude of 3 and a phase shift of π/2 is h(x) = 3 cos (2x - π/2) + 3.

The amplitude of a function is the distance between the maximum and minimum values of the function, divided by 2. The phase shift of a function is the horizontal shift of the function from the standard position,

(y = cos(x) or y = sin(x)).
To find the function with an amplitude of 3 and a phase shift of π/2, we need to look for a function that has a coefficient of 3 on the cosine term and a horizontal shift of π/2.
Looking at the given options, we can eliminate option a) because it has a coefficient of -3 on the cosine term, which means that its amplitude is 3 but it is inverted.

Option b) has a coefficient of 3 on the cosine term but it has a phase shift of -π/2, which means it is shifted to the left instead of to the right. Option d) has a phase shift of π/2, but it has a coefficient of -2 on the cosine term, which means its amplitude is 2 and not 3.
A*cos(B( x - C)) + D

Where A is the amplitude, B affects the period, C is the phase shift, and D is the vertical shift.

f(x) = -3 cos(2x - π) + 4

Amplitude: |-3| = 3

Phase shift: π (not π/2) b) g(x) = 3cos(2x + π) -1

Amplitude: |3| = 3

Phase shift: -π (not π/2) c) h(x) = 3 cos (2x - π/2) + 3

Amplitude: |3| = 3

Phase shift: π/2 d) j(x) = -2cos(2x + π/2) + 3200

Amplitude: |-2| = 2 (not 3)

Phase shift: -π/2
Therefore, the only option left is c) h(x) = 3 cos (2x - π/2) + 3. This function has a coefficient of 3 on the cosine term and a horizontal shift of π/2, which means it has an amplitude of 3 and a phase shift of π/2.

Answer:

(4, 3)

Step-by-step explanation:

Please use " ^ " to indicate exponentiation:  (x-4)^2 + 3 = f(x) (which is not 0)

Comparing:

f(x) = (x - 4)^2 + 3 to the general vertex equation

f(x) = (x - h)^2 + k

tells us that the vertex is (h, k):  (4, 3)

The sum of the measures of the second and third angles is four times the measure of the first angle.  

It can be written by:  x+y=4z

The third angle is 10 more than the second

It can be written as z=y+10

By solving the equations systems the above values can be determined.

z=y+10

The midpoint has coordinates (19,19) as per the midpoint formula.

The statement is false.

The statement is false. The midpoint of the segment joining two points is determined by taking the average of their x-coordinates and the average of their y-coordinates. In this case, the two given points are (0,0) and (38,38).

To find the x-coordinate of the midpoint, we take the average of the x-coordinates of the two points:

(x1 + x2) / 2

= (0 + 38) / 2

= 38 / 2

= 19

Therefore, the x-coordinate of the midpoint is 19, which matches the statement. However, to determine if the statement is true or false, we also need to check the y-coordinate.

To find the y-coordinate of the midpoint, we take the average of the y-coordinates of the two points:

(y1 + y2) / 2

= (0 + 38) / 2

= 38 / 2

= 19

The y-coordinate of the midpoint is also 19. Therefore, the coordinates of the midpoint are (19,19), not 19 as stated in the statement. Since the midpoint has coordinates (19,19), the statement is false.

The arc length of the given function over the interval [1,4e] is approximately 281.74 units.

The formula for arc length is given by: L = ∫[a,b]√(1+(dy/dx)²) dx

Using the given function y = 14x² - 12lnx, we can find the derivative: dy/dx = 28x - 12/x

Now, plugging this derivative into the formula for arc length and evaluating over the interval [1,4e], we get:

L = ∫[1,4e]√(1+(28x-12/x)²) dx

This integral cannot be evaluated in closed form, so we must use numerical methods to approximate the answer. One common method is to use Simpson's rule, which gives: L ≈ (4e - 1)/6 [√(1+(28(1)-12/1)²) + 4√(1+(28(2)-12/2)²) + 2√(1+(28(4e)-12/4e)²)]

L ≈ 281.74

Answer:

\(y=-\frac{5}{2}x-24\)

Step-by-step explanation:

\(2x-5y=-12\\5y=2x+12\\y=\frac{2}{5}x+\frac{12}{5}\\\)

if two lines perpendicular,

\(m_{1} .m_{2}=-1\\ \frac{2}{5} .m_{2}=-1\\m_{2}=-\frac{5}{2}\)

the line perpendicular to this line is

\(y=-\frac{5}{2}x+k\) ; k ∈ R

the line passes through the point (10,-1)

so,

\(-1=-\frac{5}{2} (10)+k\\-1=-25+k\\k=-24\)

∴the equation of the line perpendicular to 2x-5y=-12 that passes through the point (10,-1) is

Step-by-step explanation:

The sum of any three consecutive odd numbers is proved to be 11 more than a multiple of 12.

In the question, we are asked to prove that the sum of the squares of any three consecutive odd numbers is always 11 more than a multiple of 12.

We assume n to be any whole number.

Thus, we choose our 3 consecutive odd numbers as:

2n + 1, 2n + 3, and 2n + 5.

The sum of the squares of these numbers can be shown as:

(2n + 1)² + (2n + 3)² + (2n + 5)²

= (4n² + 4n + 1) + (4n² + 12n + 9) + (4n² + 20n + 25) {Using (a + b)² = a² + 2ab + b²}

= 12n² + 36n + 35

= 12n² + 36n + 24 + 11

= 12(n² + 3n + 2) + 11

= 12k + 11, where n² + 3n 2 is taken as k, any whole number as n is a whole number.

Thus, the sum is 11 more than a multiple of 12, that is, 12k.
