Answer:

The probability that the actual event is less than 6.5 inches is 0.9999.

Step-by-step explanation:

We are given that you have determined that for this gage you have a standard error of 30%.

For a precipitation event of 5 inches, we have to find the probability that the actual event is less than 6.5 inches.

The z-score probability distribution for the normal distribution is given by;

                             Z = [tex]\frac{X-\mu}{\frac{\sigma}{\sqrt{n} } }[/tex]  ~ N(0,1)

where, [tex]\mu[/tex] = mean precipitation event = 5 inches

           standard error = [tex]\frac{\sigma}{\sqrt{n} }[/tex] = 0.30

Now, the probability that the actual event is less than 6.5 inches is given by = P(X < 6.5 inches)

      P(X < 6.5 inches) = P( [tex]\frac{X-\mu}{\frac{\sigma}{\sqrt{n} } }[/tex] < [tex]\frac{6.5-5}{0.30}[/tex] ) = P(Z < 5) = 0.9999

The above probability is calculated by looking at the value of x = 5 but in the z table the last value of x is given as 4.40 so we take the area of that value only which has an area of 0.9999.

Answer:

See below.

Step-by-step explanation:

Let's let our first integer be n.

Then, our second, consecutive integer must be (n+1).

We want to prove that the sum of the square of two consecutive integers is always odd.

So, let's square our two expressions and add them up:

[tex](n)^2+(n+1)^2[/tex]

Square. Use the perfect square trinomial pattern. So:

[tex]=n^2+(n^2+2n+1)[/tex]

Combine like terms:

[tex]=2n^2+2n+1[/tex]

Notice that the first term 2n² has a 2 in front. Anything multiplied by 2 is even. So, regardless of what integer n is, 2n² is always even.

Our second term 2n also has a 2 in front. So, whatever n is, 2n is also always even.

So far, 2n² and 2n are both even. Therefore, the sum of 2n² and 2n is also even.

Lastly, we have the constant term 1. It doesn't matter what n is, we know that (2n² + 2n) is definitely and is always even. So, if we add 1 to this, we will get an odd number.

Q.E.D.

Answer:

Step-by-step explanation:

Usimg formula for calculating compound interest.

A = P(1+r/n)^nt

P is the principal =$250

r is the rate = 5%

t is the time = 25years

n = 1/4(compounded quarterly)

Substituting to get the amount A.

A = 250(1+5/25)^25/4

A = 250(1+0.2)^6.25

A = 250(1.2)^6.25

A = 250(3.125)

A = $781.31

Hence the accumulated amount in​ Jessica's annuity after 25 years is $781.31

Answer:

[tex](x+2)^2+(y-4)^2=16[/tex]

Step-by-step explanation:

OK, lets start by drawing a basic graph (the first one) so we can visualize.

We already know that the y coordinate of the circle's center is [tex]4[/tex].

We know that the circle is tangent to the [tex]X[/tex] axis at [tex](-2,0)[/tex]

That means the x coordinate of the center has to be [tex]-2[/tex], as the tangent is a point on the edge of the circle that touches a line at exactly one point.

The radius is the distance from the center of the circle to its edge. We know the center's location now, it is [tex](-2, 4)[/tex] and a point on the edge of the circle (the tangent point) which is [tex](-2,0)[/tex]. so the distance between the points is 4 which is the radius (you can use the distance formula, but it's quite oblivious.)

We can imagine the circle should look like this (the second one):

Now we can piece together an equation

The equation of a circle is [tex](x-h)^2+(y-k)^2=r^2[/tex] where [tex](h,k)[/tex] is the center and [tex]r[/tex] is the radius. When we put the numbers in: we get [tex](x-(-2))^2+(y-(4))^2=4^2[/tex] which can be simplified into [tex](x+2)^2+(y-4)^2=16[/tex] which is the answer.

Answer:

11 pages with picture to every nine pages without pictures. or 11 per every 9

Step-by-step explanation:

divide each number by a common denominator, in this case 5, to get a change from 55 per every 45 to 11 per every 9.

The required ratio of the pages with pictures to pages without pictures is 11/9.

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
A book has 55 pages with pictures and 45 pages without pictures,
The ratio of the pages with pictures to pages without pictures,
= 55 / 45
= 11 / 9
= 11 : 9

Thus, the required ratio of the pages with pictures to pages without pictures is 11/9.

Answer:

9.5 * 10^14

Step-by-step explanation:

The amount of dollars needed to cover the united states is 9.5×10¹⁴ dollars. The correct option is B.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

It is given that Tyler’s math class found that it would take 2.5×10⁸ dollar bills to cover a square mile area. The surface area of the United States is about 3.8×10⁶ square miles.

The number of dollars will be calculated as below:-

A = [ ( 2.5×10⁸) x  (3.8×10⁶) ]

A = ( 9.5 x 10¹⁴ ) dollars.

Therefore, the amount of dollars needed to cover the united states is 9.5×10¹⁴ dollars. The correct option is B.

Answer:

[tex] \huge{ \boxed{ \bold{ \tt{46 \degree}}}}[/tex]

Step-by-step explanation:

Remember that the sum of complementary angles is always 90°.

First, finding the value of x :

Set up an equation :

[tex] \sf{(2x + 30) + (7x - 3) = 90°}[/tex] ( Being complementary angles )

Solve for x

[tex] \sf{⇢2x + 30 + 7x - 3 = 90°}[/tex] { Remove unnecessary parentheses }

[tex] \sf{⇢9x + 30 - 3 = 90°}[/tex] { Combine like terms }

[tex] \sf{⇢9x + 27 = 90°}[/tex] { Subtract 3 from 30 }

[tex] \sf{⇢ \: 9x = 90° - 27}[/tex] { Move 27 to right hand side and change it's sign }

[tex] \sf{⇢ \: 9x = 63°}[/tex] { Subtract 27 from 90}

[tex] \sf{⇢ \: \frac{9x}{x} = \frac{63°}{9}} [/tex] { Divide both sides by 9 }

[tex] \sf{⇢ \: x = 7°}[/tex]

The value of X is 7°

Now, Replacing the value of x in order to find the value of [tex] \angle[/tex] B

[tex] \sf{(7x - 3)°}[/tex]

[tex] \sf{⇢ \: (7 \times 7 - 3)°}[/tex] { Plug the value of x }

[tex] \sf{⇢ \: (49 - 3)°}[/tex] { Multiply 7 by 7 }

[tex] \sf{⇢ \boxed{46°}}[/tex] { Subtract 3 from 49 }

The measure of [tex] \angle[/tex] B is 46°

And we're done!

Answer:

The answer is 390 × pi.

Step-by-step explanation:

Big cone:

V = 1/3 x pi x r^2 x h

= 1/3 x 3.14 x 9^2 x 15

= 1272.3 cubic inches

Small cone:

V = 1/3 x pi x r^2 x h

= 1/3 x 3.14 x 3^2 x 5

= 47.1 cubic inches  

1272.3 - 47.1 = 1225.2 cubic inches

1272/3.14 ≈ 390

The answer is 390 × pi.

3 x 7 = 21.

Now we add 9.

21 + 9 = 30.

Answer:

2520

Step-by-step explanation:

2520

The equation y = -4 cos(πx - 2) represents a cosine function with specific parameters.

Amplitude: The amplitude of the function is given by -4. The negative sign indicates that the graph will be reflected across the x-axis, resulting in a downward orientation.

Period: The period of the cosine function is determined by the coefficient of x inside the cosine function, which is π (pi) in this case. The period (T) can be calculated using the formula T = 2π/|B|, where B is the coefficient of x. In our equation, T = 2π/|π| = 2. Therefore, the graph will complete one full period over the interval [0, 2].

Phase Shift: The phase shift is determined by the constant inside the cosine function, which is -2 in this case. The phase shift (C) can be calculated using the formula C = D/B, where D is the constant inside the cosine function and B is the coefficient of x. In our equation, C = -2/π. Since the phase shift is subtracted from x, the graph will shift 2 units to the right.

Vertical Shift: There is no vertical shift in this equation, as there is no constant term added to the cosine function.

Based on these parameters, we can draw the graph of y = -4 cos(πx - 2). Here are the key characteristics:

The graph will have a downward orientation due to the negative amplitude.

The graph will have a period of 2, meaning it will repeat every 2 units along the x-axis.

The graph will be shifted 2 units to the right due to the phase shift.

To plot the graph, we can start by marking the key points:

At x = 0, the cosine function starts at its maximum value of 1. Since the amplitude is -4, the corresponding y-value would be -4.

Moving to the right by 1 unit (due to the period), we reach x = 1. At this point, the cosine function reaches its minimum value of -1. The corresponding y-value would be -4 * (-1) = 4.

Continuing in this manner, at x = 2, the cosine function completes one full period and returns to its maximum value of 1. The corresponding y-value would be -4.
