A sun in a distant galaxy has an estimated Mass of 1.55272 x [tex]10^{31}[/tex]kg

earth has a mass of 5.972 x [tex]10^{24}[/tex]kg

Let x number of earths equal the mass of the sun

x (5.972 x [tex]10^{24}[/tex]) =  1.55272 x [tex]10^{31}[/tex]

x=  1.55272 x [tex]10^{31}[/tex] / 5.972 x [tex]10^{24}[/tex]

x= 26x[tex]10^{5}[/tex]

The wavelength of light emitted by a far-off galaxy extends and is "redshifted" toward the infrared region of the electromagnetic spectrum as it moves away from us. This means that by the time the light from a very distant galaxy that emits mostly visible or ultraviolet light reaches Earth, it will appear as infrared light.

Webb's ability to detect infrared light and the cosmos' expansion, which extends light to redder wavelengths, make it a good tool for identifying galaxies that originated at the beginning of the Universe's existence.

Using integrals, the desired probabilities and measures are given as follows:

a) P(X < 6) = 0.84375 = 84.375%.

b) P(X < 13) = 1 = 100%.

c) P(6 < X < 8) = 0.15625 = 15.625%.

d) P(X > 5) = 0.31641 = 31.641%.

e) x = 6.434.

The distribution is given as follows, simplifying the operations:

f(x) = 0.09375x - 0.01171875x², 0 ≤ x ≤ 8.

Hence the density function is:

[tex]\int_{a}^{b} f(x) dx[/tex]

[tex]\int_{a}^{b} (0.09375x - 0.01171875x^2) dx[/tex]

[tex]0.046875x^2 - 0.00390625x^3|_{x=a}^{x = b}[/tex]

Applying the Fundamental Theorem of Calculus:

P(a < X < b) = 0.046875b² - 0.00390625b³ - 0.046875a² + 0.00390625a³

Hence, for item a:

P(X < 6) = 0.046875(6)² - 0.00390625(6)³.

P(X < 6) = 0.84375 = 84.375%.

For item b, the entire distribution is below 13, hence:

P(X < 13) = 1 = 100%.

For item c:

P(6 < X < 8) = 0.046875(8)² - 0.00390625(8)³ - 0.046875(6)² + 0.00390625(6)³.

P(6 < X < 8) = 0.15625 = 15.625%.

For item d:

P(5 < X < 8) = 0.046875(8)² - 0.00390625(8)³ - 0.046875(5)² + 0.00390625(5)³.

P(X > 5) = 0.31641 = 31.641%.

For item e:

We have to find b when a = 0 and P(X < b) = 0.9, hence:

0.046875b² - 0.00390625b³ = 0.9.

Using a calculator, the solution in the range of the distribution is given by:

b = x = 6.434.

There is no number which is satisfying the given conditions.

The first condition is that the number has seven digits.

The second condition is that the number lies between 1000 and 10000.

From these two conditions, we can conclude that there is no number which satisfies all the given conditions. Because there is no seven-digit number which is less than 10000.

Let us assume that the second condition is the number lies between 1000000 and 10000000.

And let the required number be "abcdefg".

The third condition is the digit in the tenth place is 150% of the digit in the thousandth place.

⇒ f = 150 × (d) / 100 = 1.5 × d

The fourth condition is the digit in the hundredth place is the sum of the digit in the tenth place and the digit in the thousandth place.

⇒ e = f + d = 1.5d + d = 2.5d

The fifth condition is the sum of all the digits in the number is 17.

⇒ a + b + c + d + e + f + g = 17

⇒ a + b + c + d + 2.5d + 1.5d + g = 17

⇒ a + b + c + 5d + g = 17

And the last condition is none of the digits is zero.

Using the last condition the possible values for d are either 1 or 2.

Because, if d is 3, then if we take the least possible digit(1) for others, the sum on the LHS is 19, which is greater than 17.

And d can not be 1. Because, if d is 1, then f and e are 1.5 and 2.5 respectively. 1.5 and 2.5 are not valid digits.

Therefore, the value of d = 2.

f = 1.5d = 3

e = 2.5d = 5

If d = 2, then we get a + b + c + g + 10 = 17

⇒ a + b + c + g = 17 - 10

⇒ a + b + c + g = 7

⇒ The possible values for (a, b, c, g) are (4, 1, 1, 1), (1, 4, 1, 1), (1, 1, 4, 1), (1, 1, 1, 4), (2, 2, 2, 1), (2, 2, 1, 2), (2, 1, 2, 2), (1, 2, 2, 2), (2, 3, 1, 1), (3, 2, 1, 1), (1, 1, 2, 3), and (1, 1, 3, 2)...

Yes; The construction demonstrates how to bisect an angle correctly using technology because Circles D & E have the same radius

How to properly bisect an angle?

In construction of angles and lines, bisection means dividing either a given angle or line segment into two equal parts. This means after the construction, the two parts must have equal measure.

The steps to bisect a line segment are as follows;

1. Draw the required length of the line segment AB.

2. With point A and radius of the compass greater than half of AB, describe arcs above and below the segment.

3. With the same radius as in step 2 and point B, describe two arcs above and below the segment. These would intersect that of step 2 at C and D.

4. Join the points of intersection of the arcs with a straight line CD.

Now, in this given question with the circle, we can see that line AG is the line that bisects the angle EAD.

Now, we see that circles C and D have the same radius and as such the construction demonstrated is correct for that very reason.

Answer: yes

Step-by-step explanation: the construction correctly shows how to bisect an angle using technology because circles D and E have the same radius. 

If the percentage increase between 2017 and 2018 continued for 2018 and 2019, there would be 10332908 millionaire households in 2019

The given parameters are:

Year Millionaire Households

2015 9,200,000

2016 9,350,000

2017 9,620,000

2018 9,970,000

From the question, we have

The percentage increase between 2017 and 2018 continued for 2018 and 2019

The percentage increase between 2017 and 2018 is calculated as

Percentage = (2018 - 2017)/2017 * 100%

So, we have

Percentage = (9,970,000 - 9,620,000)/9,620,000 * 100%

Evaluate

Percentage = 3.64%

The number of millionaire households in 2019 is calculated as

2019 = 2018 * (1 + percentage)

So, we have

Households = 9,970,000 * (1 + 3.64%)

Evaluate

Households = 10332908

Hence, if the percentage increase between 2017 and 2018 continued for 2018 and 2019, there would be 10332908 millionaire households in 2019

Answer:

  1000

Step-by-step explanation:

You want the next number after 222 in base 3.

In any useful number base, the counting at any given integer position is ...

  0, 1, 2, 3, ..., (base -1), 0 and add 1 to the next number position

For base 3, this is ...

  0, 1, 2, 10

When the digit in the next higher position is also (base -1), then it gets incremented to 0 and the carry is propagated to the left.

In base 10, the equivalent is ...

  999 +1 = 99(9+1) = 99(10) = 9(9+1)0 = 9(10)0 = (9+1)00 = 1000

In base 3, your incremented value is ...

  222 +1 = 22(2+1) = 22(10) = 2(2+1)0 = 2(10)0 = (2+1)00 = 1000

The next whole base 3 number after 222 is 1000.
