What is the difference between 7,001 and 433?

first we have to put the numbers in order

1/2, 3/5, (5/8, 1 1/4), 1 1/2, 1 3/4

the median is the middle number. when there is an odd number of numbers, u will have 1 middle number. But when there is an even number of numbers, like this one, there will be 2 middle numbers. So u have to take ur 2 middle numbers, add them, then divide them by 2 to get the average median.

are 2 middle numbers are : 5/8 and 1 1/4..

(5/8 + 1 1/4) / 2 = (5/8 + 5/4) / 2 = (5/8 + 10/8) / 2 = 
(15/8) / 2 = 15/8 * 1/2 = 15/16 <==

Use the sine law: sinB/b = sinA/a

SinB = b*sinA/a

sinB = 3*sin120° /8

∠ B = 18.94° ≈ 19°

Answer:

∠B = 19°

Step-by-step explanation:

Given : In triangle ABC, if ∠A = 120°, a = 8, and b = 3

We have to find the measure of B that is ∠B

Consider the given triangle ABC,

Using Sine rule ,

For a triangle with measure of angle A, B and C and side  a faces angle A,  

side b faces angle B and  side c faces angle C

[tex]\frac{a}{\sin A}=\frac{b}{\sin B}=\frac{c}{\sin C}[/tex]

we have, a = 8 , b = 3 and ∠A = 120°

Consider first two ratios,

[tex]\frac{8}{\sin 120^{\circ}}=\frac{3}{\sin B}[/tex]

Solve for B, we have,

[tex]\sin \left(120^{\circ \:}\right)=\frac{\sqrt{3}}{2}[/tex]

[tex]\frac{8}{\frac{\sqrt{3}}{2}}=\frac{3}{\sin \left(B\right)}[/tex]

[tex]\mathrm{Apply\:fraction\:cross\:multiply:\:if\:}\frac{a}{b}=\frac{c}{d}\mathrm{\:then\:}a\cdot \:d=b\cdot \:c[/tex]

[tex]8\sin \left(B\right)=\frac{\sqrt{3}}{2}\cdot \:3[/tex]

Simplify, we have,

[tex]\sin \left(B\right)=\frac{3\sqrt{3}}{16}[/tex]

Taking sine inverse both side, we have,

[tex]B=\sin^{-1}\left(\frac{3\sqrt{3}}{16}\right)[/tex]

We have, [tex]B=18.95^{\circ \:}[/tex]

Thus, ∠B = 19°

a. Yule-Simons PMF is valid due to non-negativity and sum 1 proof.

b. E[X] = 2 calculated through partial fraction and cancellation.

c. E[X^2] = ∞ shown using comparison test with p-series.


a. Proving it's a Probability Mass Function (PMF):

Condition 1: Non-negativity: P{X = n} = 4/(n(n + 1)(n + 2)) is always positive for n ≥ 1, as all factors in the denominator are positive.

Condition 2: Sums to 1:

We need to show ∑_(n=1)^∞ P{X = n} = 1.

Use partial fraction decomposition:

4/(n(n + 1)(n + 2)) = 1/(n) - 1/(n + 1) + 1/(2(n + 2))

Expand the infinite series:

∑_(n=1)^∞ P{X = n} = (1/1 - 1/2 + 1/6) + (1/2 - 1/3 + 1/8) + ...

Notice terms cancel out:

= 1 + (1/6 - 1/6) + (1/8 - 1/8) + ... = 1

Therefore, P{X = n} is a valid PMF.

b. Expectation E[X] = 2:

E[X] = ∑_(n=1)^∞ n * P{X = n}

Substitute P{X = n} with its expression:

E[X] = ∑_(n=1)^∞ n * (4/(n(n + 1)(n + 2)))

Apply partial fraction decomposition (as in a) and simplify:

E[X] = ∑_(n=1)^∞ (1/(n + 1) - 2/(n + 2))

Expand the series and observe cancellations:

E[X] = (1/2 - 2/3) + (1/3 - 2/4) + ... = 1 - 1/2 = 1/2

Multiply by 4 to account for the 4 in the original PMF:

E[X] = 4 * (1/2) = 2

Therefore, E[X] = 2.

c. Expectation E[X^2] = ∞:

E[X^2] = ∑_(n=1)^∞ n^2 * P{X = n}

Substitute P{X = n} and simplify:

E[X^2] = ∑_(n=1)^∞ (4n/(n + 1)(n + 2))

Use the comparison test:

4n/(n + 1)(n + 2) > 4n/(n^3) = 4/(n^2) for n ≥ 1

Since ∑_(n=1)^∞ 4/(n^2) (p-series with p = 2) converges, so does E[X^2].

Therefore, E[X^2] = ∞.

The answer is incorrect because there are 1000 meters in 1 kilometer, not 1000 kilometers in a meter, the answer should've been 68 times 10^3 which makes it 6,800 meters.

Final answer:

The conversion of 68 kilometers into meters gives 68000 meters, not 0.068 meters. The error arises due to dividing instead of multiplying the kilometers by 1000 (because 1 km equals 1000m).

Explanation:

When you are converting from kilometers to meters, you need to understand that 1 kilometer is equal to 1000 meters. Therefore, to convert 68 kilometers to meters, you should multiply 68 by 1000, not dividing it. You calculate 68km * 1000 = 68000m. So, 68 kilometers is equal to 68,000 meters, not 0.068 meters. The response 0.068 meters is incorrect because it is vastly smaller than the actual conversion result.

C. y=3x+1 is the answer.

Answer:

Step-by-step explanation:

The line has positive slope, therefore the variable in the equation must be positive ([tex]y=-3x+1[/tex] and [tex]y=-3x-1[/tex] must be discarded)

Now, in the graph we can see that the line passes over the following points:

[tex](0,1) \rightarrow x=0, y=1\\(1,4) \rightarrow x=1, y=4[/tex]

With the point [tex](0,1)[/tex], we can discard [tex]y=3x-1[/tex] because:

in the equation  [tex]y=3x-1[/tex], we have: [tex]x=0 \rightarrow y=3(0)-1=0-1=-1\rightarrow y=-1[/tex]

The line doesn't pass over the point [tex](0,-1)[/tex]

Therefore, the equation is [tex]y=3x+1[/tex].

The distance of the bird from its starting point will be 29.15 miles.

What is Pythagoras theorem?

The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.

Given that;

A bird flies 25 miles Due West then turns due south and flies for another 15 miles and lands.

Now,

Since, A bird flies 25 miles Due West then turns due south and flies for another 15 miles and lands.

Let the distance of the bird from its starting point = x

So, By using Pythagoras theorem, we get;

⇒ x² = 15² + 25²

⇒ x² = 225 + 625

⇒ x² = 850

⇒ x = √850

⇒ x = 29.15 miles

Final answer:

To find points where the tangent plane to an ellipsoid is parallel to a plane, calculate the gradient vector of the ellipsoid and set it proportional to the normal vector of the given plane, then solve the resulting system for  (x, y, z).

Explanation:

To find all the points where the tangent plane to an ellipsoid is parallel to a given plane, you first need to consider the equation of the ellipsoid and the equation of the tangent plane.

The ellipsoid can be described by the general equation  f(x, y, z) = 0, while the tangent plane at a point on the ellipsoid can be described by the gradient of f at that point, given as  ∇f.

The gradient, which is a vector, gives us the normal to the tangent plane at the given point.

For a tangent plane to be parallel to another plane, their normal vectors must be proportional.

So, if we have the normal vector of the given plane, we can set up an equation with the gradient of the ellipsoid, and solve for the points (x, y, z) that satisfy this condition.

It requires solving a system of equations where the coefficients of the normals to both planes are proportional.

These points  (x, y, z) will be the points of tangency where the ellipsoid's tangent plane is parallel to the given plane.

We use the calculus concepts of partial derivatives to find the gradient vector and algebra to solve for the unknowns corresponding to the points of tangency.

The probability that at least one of the five light bulbs is defective is approximately 26.61%. This is found by calculating the probability that all bulbs work ([tex]0.94^5[/tex]) and subtracting that from 1.

The student is asking about the probability of having at least one defective light bulb in a pack of five, given a defect rate of 6%. To calculate this, we will use the complement rule, which states that the probability of at least one success is equal to 1 minus the probability of zero successes (no defective bulbs).

First, we calculate the probability that a bulb is not defective, which is 94% or 0.94 (since 100% - 6% = 94%). Since the bulbs are independent, the probability that all five bulbs are not defective is:

[tex](0.94)^5[/tex]

The probability that at least one bulb is defective is thus:

1 - [tex](0.94)^5[/tex]

Using a calculator, this gives us:

[tex]1 - (0.94^5) \approx 1 - 0.7339 \approx 0.2661 or 26.61%[/tex]

So, there is approximately a 26.61% chance that at least one of the five light bulbs is defective.

The probability that at least one of the light bulbs is defective is approximately 0.264909 or 26.49%.

To find the probability that at least one of the light bulbs is defective, we can use the complement rule.

The complement rule states that the probability of an event occurring is equal to 1 minus the probability of the event not occurring.

In this case, the event of interest is that at least one light bulb is defective. The complement of this event is that none of the light bulbs are defective.

Given that 6% of the light bulbs are defective, the probability that any one light bulb is not defective is 1 - 0.06 = 0.94.

Since each light bulb operates independently of the others, the probability that none of the five light bulbs are defective is [tex]\((0.94)^5\)[/tex].

Therefore, the probability that at least one of the light bulbs is defective is [tex]\(1 - (0.94)^5\)[/tex].

Let's calculate it:

P(at least one defective) = 1 - (0.94)^5

P(at least one defective) = 1 - 0.735091 = 0.264909

So, the probability that at least one of the light bulbs is defective is approximately 0.264909 or 26.49%.

1 and 3/4 would be the mixed number that represents the length of each piece. You would get this number by dividing 7 by 4 :)

Final answer:

When a 7-foot board is divided into 4 equal pieces, each piece will be 1.75 feet, or, as a mixed number, 1 3/4 feet.

Explanation:

To figure out the length of each piece when a 7-foot board is divided into 4 equal parts, we perform division. We divide the total length of the board by the number of pieces. That is, 7 ÷ 4 = 1.75.

This is a decimal number. To express it as a mixed number, we remember that '.75' is the same as '75/100', and this fraction can be simplified to '3/4'. So, 1.75 feet is the same as 1 3/4 feet. Therefore, each piece of board will be 1 3/4 feet long.

She will pack 1 crate that holds 1,000 and 25 stacks that hold 10.
1,250-1,000=250
250÷10=25

Shawna can pack an order of 1,250 blocks using 1 crate for the thousands and 25 stacks for the tens.

To pack 1,250 blocks using crates and stacks, we need to break down the total number of blocks into thousands and tens:

Step 1: Determine the number of crates (each crate holds 1,000 blocks). 1,250 blocks divided by 1,000 equals 1 crate (1,000 blocks).Step 2: Subtract the blocks already packed in crates: 1,250 - 1,000 = 250 blocks.Step 3: Determine the number of stacks (each stack holds 10 blocks). 250 blocks divided by 10 equals 25 stacks (250 blocks).Therefore, Shawna can pack the order with 1 crate and 25 stacks.

Answer:

2/35

Step-by-step explanation:

The only way we can solve this problem is to assume that the given complement of pieces is of a full kit before one went missing. The total number of pieces in the kit is ...

... 9 + 8 + 12 + 6 = 35

Of those, 2 are red with four holes. Thus the probability that a randomly chosen piece is red with 4 holes is 2 out of 35, or 2/35.

____

If this is the kit contents after the piece went missing, we have no way of knowing the color or hole count of the missing piece. If the kit is supposed to contain 13 blue pieces, for example, then the probability is zero that the missing piece is red.

Final answer:

The probability of a specific event is determined by dividing the number of ways this event can occur by the total number of possible outcomes. In this case, the probability of selecting a red piece with four holes from the toy building kit is the ratio of the quantity of four-holed red pieces to the total quantity of pieces in the kit.

Explanation:

The question refers to the probability of a specific event in a set of outcomes related to a toy building kit. In this case, the event is selecting a red piece with four holes. Probability can be defined mathematically as (Number of ways event can occur)/(Total number of outcomes). Specifically, in your case, you would calculate the number of four-holed red pieces within the whole toy building kit. Divide that by the total number of pieces in the entire kit, including the missing one.

Using an example with different objects for clarity, consider if there are 10 pieces in the set, and 3 of them are four-holed red pieces, the probability of the selected piece being a four-holed red piece would be 3/10 or 0.3 (once converted to decimal form). This method can now be applied to your toy building set once you identify the total number of pieces in the set and the number of these that are four-holed red pieces.

The statement "a sample of n = 9 scores is randomly selected from a population with m = 80 and s = 9 is false.

What is a normal distribution?

It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.

It is given that:

A sample of n = 9 scores is randomly selected from a population with m = 80 and s = 9.

As we know,

Z = (x - u)/s

Z = 3

x = 83

s = 9

3 = (83 - u)/9

27 = 83 - u

u = 83 - 27 = 56

Thus, the statement "a sample of n = 9 scores is randomly selected from a population with m = 80 and s = 9 is false.

1,330,000 is the answer.

Probably late lol

3.14 is the answer
hope it helped!

pi is equal to 3.14159265....

or just 3.14

3.14 is your answer

hope this helps

The answer to your question is that she can make 17 trains of 10 cubes so the answer is 17 

10 is the initial value, found when x=0.  I don't know what you are measuring by "0" and "10" here, so can't be more specific.

goes up five everytime

i see a pattern that each number increases by 5

[tex]\displaystyle\sum_{n=1}^\infty(-1)^{n-1}\tan^{2n}\theta=1-\sum_{n=0}^\infty(-\tan^2\theta)^n=1-\dfrac1{1+\tan^2\theta}[/tex]

where [tex]|-\tan^2\theta|=\tan^2\theta<1[/tex] in order that the series converges, which is to say the series converges for

[tex]\tan^2\theta<1\implies|\tan\theta|<1\implies|\theta|<\dfrac\pi4[/tex]

We can simplify the sum a bit further, noting that [tex]1+\tan^2\theta=\sec^2\theta[/tex], giving

[tex]\displaystyle\sum_{n=1}^\infty(-1)^{n-1}\tan^{2n}\theta=1-\cos^2\theta=\sin^2\theta[/tex]
