Answer:

(9,9)

Step-by-step explanation:

Assuming the point is exactly halfway between A and B, to find it we just need to find the centre point between (4,8) and (14,10).

To find the midpoint, we just need to find the middle value, by dividing the difference between the x values by 2, and repeating the process with the y values.

This is because the point is in the middle, so it's y value will be in the middle of the given AB y values, and its x value will also be directly in the middle of the AB x values.

The x values are 4 and 14. The midpoint is

14-4=10

10/2=5 (the midpoint is 5 away from each reference point)

4+5=9

The midpoint is 9 for the x values. This means the x-value for the point is 9.

Repeat for y-values:

10-8=2

2/2=1

8+1=9

The midpoint is 9, therefore it has the y coordinate of 9.

Therefore the coordinates for the point are (9,9).

Hope this helped!

The quotient and remainder, written as partial fractions, of 15x^2+52x+43/3x^2+5x-8 would be  [tex]\dfrac{A}{(3x + 8)} + \dfrac{B}{(x-1)}[/tex] where A is -8/3 and B is 1.

We can use the fact that division can be taken as multiplication but with the denominator's multiplicative inverse.

[tex]\dfrac{15x^2+52x+43}{3x^2+5x-8}\\\\\\\dfrac{15x^2+52x+43}{3x^2+(8-3)x-8}\\\\\\\dfrac{15x^2+52x+43}{3x^2+8x-3x-8}\\\\\\\dfrac{15x^2+52x+43}{3x(x -1)+8(x - 1)}\\\\\\\dfrac{15x^2+52x+43}{(3x + 8)(x - 1)}[/tex]

 [tex]\dfrac{A}{(3x + 8)} + \dfrac{B}{(x-1)}[/tex].

To find the value of A;

3x + 8 = 0

x = -8/3

To find the value of B;

x - 1 = 0

x = 1

Therefore, The quotient and remainder, written as partial fractions, of 15x^2+52x+43/3x^2+5x-8 would be  [tex]\dfrac{A}{(3x + 8)} + \dfrac{B}{(x-1)}[/tex] where A is -8/3 and B is 1.

Answer:

The 90th percentile for the life span of the Galápagos Islands giant tortoise is 119.4 years.

Step-by-step explanation:

Let X denote the  life span of the Galápagos Islands giant tortoise.

It is provided that x follows a normal distribution with mean 100 years and standard deviation 15 years.

Compute the 90th percentile value as follows:

P (X < x) = 0.90

⇒ P (Z < z) = 0.90

The corresponding value of z is, z = 1.29.

Compute the value of x as follows:

[tex]z=\frac{x-\mu}{\sigma}\\\\1.29=\frac{x-100}{15}\\\\x=100+(1.29\times 15}\\\\x=119.35\\\\x\approx 119.4[/tex]

Thus, the 90th percentile for the life span of the Galápagos Islands giant tortoise is 119.4 years.

The closest estimate to the age of a Galápagos Islands giant tortoise at the 90th percentile of the  distribution is 119.35 years

The given parameters are:

[tex]\mathbf{\mu = 100}[/tex] -- population mean

[tex]\mathbf{\sigma = 15}[/tex] --- standard deviation

[tex]\mathbf{p = 90\%}[/tex] --- p-value

The z value at p-value = 90% is 1.29

So, we have:

[tex]\mathbf{z = 1.29}[/tex]

The formula for z-value is:

[tex]\mathbf{z = \frac{x - \mu}{\sigma}}[/tex]

So, we have:

[tex]\mathbf{1.29 = \frac{x - 100}{15}}}[/tex]

Multiply both sides by 15

[tex]\mathbf{19.35= x - 100}[/tex]

Add 100 to both sides

[tex]\mathbf{x = 119.35}[/tex]

Hence, the closest estimate is 119.35 years

Step-by-step explanation:

1.386 billion =  1,386,000,000

Now we want to round this to the nearest hundred million (it is the 9th digit counting from right to left).

To round, we need to look at the digit at the right ( the 8th in this case)

If that digit is equal or larger than 5, then we round up. (we add 1 to the 9th decimal in this case)

If that digit is smaller than 5, we round down.

In this case, the 8th digit is an 8, this is larger than 5, then we round up.

1,386,000,000 ≈ 1,400,000,000

The value of [tex]x[/tex] is [tex]\frac{25}{2}[/tex].

Step-by-step explanation:

From Analytical Geometry we get that ratio of BC to BE is:

[tex]\frac{BC}{BE} = 2[/tex] (From definition of midpoint)

[tex]\frac{BE+CE}{BE} = 2[/tex]

[tex]1 + \frac{CE}{BE} = 2[/tex]

[tex]\frac{CE}{BE} = 1[/tex]

[tex]CE = BE[/tex]

If we know that [tex]BE = 50[/tex] and [tex]CE = 2\cdot x + 25[/tex], then, the equality above is expanded:

[tex]2\cdot x +25 = 50[/tex]

[tex]2\cdot x = 25[/tex]

[tex]x = \frac{25}{2}[/tex]

The value of [tex]x[/tex] is [tex]\frac{25}{2}[/tex].

Answer:

1 : 3  is related to 3 : 9

Step-by-step explanation:

According to ratios you can always divide  them if they are even numbers like for example the ratio, 6 : 9 is uneven but you can divide each number by 3 and you get a ratio of 2 : 3. and they are both alike because if you go back and multiply each number by three you get the same ratio that you had before.

Answer:

[tex](9/2, 3/2)[/tex]

Step-by-step explanation:

We have the equation:

[tex]3x+y=15[/tex]

Which is equivalent to 15 among all pairs of (x, y).

We want to find the pair of solutions (x, y) such that:

[tex]x^2+y^2[/tex]

Is minimum.

Note that our given equation is a line.

And the equation x²+y² is a circle centered on the origin.

In other words, we want to find the radius of the circle such that it is tangent to our line at 3x+y=15.

It must be tangent because this guarantees that it is the smallest value of  x²+y².

It's good if we have a visual of this. I've graphed the given linear equation. Please refer to it.

If you remember in geometry, in order for the radius to be tangent to a line, the radius must be perpendicular to our line.

So, let's find the perpendicular equation to our line. Our original equation is:

[tex]3x+y=15[/tex]

Subtract 3x from both sides:

[tex]y=-3x+15[/tex]

So, the slope of our original equation is -3.

This means that the slope of our perpendicular line must be the negative reciprocal of -3. Namely, it is 1/3.

And since our circle is centered on the origin, this line will go through the origin. Therefore, our perpendicular equation is:

[tex]y=\frac{1}{3}x[/tex]

Graphing this will yield (please refer to the second graph):

Therefore, the intersection between our old and new line is at (4.5, 1.5).

Therefore, the (x, y) value that grants the minimum sum is 9/2 and 3/2.

We can check this by substituting them into our second equation. This yields:

[tex](9/2)^2+(5/2)^2[/tex]

Square and add:

[tex]=81/4+9/4=22.5[/tex]

Note that 22.5 is the radius squared.

Graphing this gives us (please refer to the third graph):

We can see that it is indeed tangent to our line. And it is the lowest value of P that does so.

So, our answer is x=9/2 and y=3/2.
