Answer:
10 billion
Step-by-step explanation:
It is important to take 40% from 150 billion, and then 10% also from 150 billion, and not what is left after the 40% deduction.
I will write 150 Billion as 150b.
Therefore: 150b x 0.4 (0.4 is a change factor to find 40%). will give you 60000000000. or 60 billion.
150b - 60000000000 will give you 90 billion.
Then, 150 billion times 0,1 (change factor for 10%). Will give you 15000000000 or 15 billion.
Now do 90 billion minus 15 billion = 75 billion.
Now do the same for the rest.
13% of 150 billion is 19,5 billion. 75 billion - 19,5 billion = 55 billion.
30% of 150 billion is 45 billion. 55 billion - 45 billion is 10 billion.
Therefore 10 Billion is left over.

i need the solution/explanation on how you got the answer
(y + 3) = -8(x - 4)
what is the slope?
Answer:
slope m = - 8
Step-by-step explanation:
the equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
y + 3 = - 8(x - 4) ← is in point- slope form
with slope m = - 8
The slope is :
↬ -8Solution:
Given: \(\bf{y+3=-8(x-4)}\)
To determine the slope, it's important to know the form of the equation first.
There are 3 forms that you should be familiar with.
The three forms of equations of a straight line are:
Slope Intercept (y = mx + b)Point slope (y-y₁) = m(x - x₁)Standard form (ax + by = c)This equation matches point slope perfectly.
The question becomes, how do you work with point slope to find slope?
Point slopeIn point slope, m is the slope and (x₁, y₁) is a point on the line.
Similarly, the slope of \(\bf{y+3=-8(x-4)}\) is -8.
Hence, the slope is -8.An approximate way to calculate the number of balls that will
fit into a box would be to take the volume of the box and divide by
the volume of the ball. So let us take a box 2 feet (24 inches) on a side. First, what amount of space does this represent? To answer this, use the scale factor to compute how many parsecs 2 feet (24 inches) represents.
Represented 'box' size in space ______________ parsecs
The represented 'box' size in space, which is 2 feet (24 inches) on a side, is approximately 6.47 ×\(10^(^-^1^7^)\) parsecs.
To calculate the amount of space represented by a box that is 2 feet (24 inches) on a side, we need to convert the length in feet to parsecs. A parsec is a unit of length used in astronomy to measure vast distances.
First, we need to determine the scale factor that relates feet to parsecs. The conversion factor is based on the definition that 1 parsec is approximately equal to 3.09 × \(10^1^6\) feet.
To find the represented 'box' size in space in parsecs, we can use the following calculation:
Represented 'box' size (in parsecs) = Box size (in feet) / Conversion factor
Box size (in feet) = 2 feet
Conversion factor = 3.09 ×\(10^1^6\)feet/parsec
Substituting the values into the equation, we have:
Represented 'box' size (in parsecs) = 2 feet / (3.09 × \(10^1^6\)feet/parsec)
Simplifying the expression:
Represented 'box' size (in parsecs) = 2 / (3.09 × \(10^1^6\)) parsecs
Calculating the result:
Represented 'box' size (in parsecs) ≈ 6.47 ×\(10^(^-^1^7^)\) parsecs
In other words, the box's spatial representation corresponds to approximately 6.47 × \(10^(^-^1^7^)\)parsecs.
It is important to note that this calculation assumes a linear scale and does not account for the complexities of space and the actual distribution of objects. The approximation provides a rough estimate of the spatial representation of the given box size in parsecs.

What is the slope of a line perpendicular to the line whose equation is
3x−12y=−108. Fully simplify your answer
Answer:
Step-by-step explanation:
The given equation is not instandard form. First standard form is neccesary.
Add 108 to both sides.Subtract 12y to both sidesThe result is 3x + 108 = 12y which is equal to 12y = 3x + 108
The slope is represented in this form as m (Y = mx + b)
(with b as the initial value)
Therefore, 3 is the slope.
To find its perpendicular slope.
To find it's perpendicular, know that it is the negative reciprocal.
First negate 3 to become -3 and find it's reciprocalTo find the reciprocal, divide 1 by -3FInally, the slope perpendicular to the line whose equation is 3x - 12y = -108 is \(\frac{1}{-3\\}\)
suppose x ~ n(15, 3). between what x values does 68.27% of the data lie? the range of x values is centered at the mean of the distribution (i.e., 15).
For provide normal distribution such that
x ~ n(15, 3), 68.27% of the data lie between the values of x as x= 12 to x= 18 .The range of x-values is centered around the mean of the distribution (that is, 15).
Normal Probability:
This problem uses the Z-score formula to calculate the range such that 68.27% of the data falls within the range. Z-scores are normal scores, plotted on a normal curve with mean 0 and variance 1. The Excel function NORM.S.INV() is used to get the score value.
We have given that
Mean, μ = 15
Standard deviation, σ = 3
P( a <X<b) = 0.6827
P( (a − μ)/(σ < X − μ )/σ <(b− μ)σ) = 0.6827
P ( a- 15) /3 < Z < (b- 15)/3) = 0.6827
P( Z< (b-15)/3) - P( Z< ( a - 15)/3) = 0.6827
1 - P( Z > (b-15)/3) - P( Z< ( a - 15)/3) = 0.6827
(Symmetrical Property)
We know that,
P( Z> (b-15)/3) = P( Z< ( a - 15)/3) ( symmetric)
2 × P( Z< ( a - 15)/3) = 0.3173
P( Z< ( a - 15)/3) = 0.15865
Now,
Excel function for the value of z score:
=NORM.S.INV(0.15865)
(a − 15)/3 = -1.00
=> a-15 = -3
=> a = 12 and b = 15 + 3 = 18
Hence, the values of x are 12 and 18 where 68.27% data lie.

The probability of x taking on a value between 75 to 90 is 0.25.
Given that x is a continuous random variable uniformly distributed between 65 and 85.To find the probability that x lies between 75 and 90, we need to find the area under the curve between the values 75 and 85, and add to that the area under the curve between 85 and 90.
The curve represents a rectangular shape, the height of which is the maximum probability. So, the height is given by the formula height of the curve = 1/ (b-a) = 1/ (85-65) = 1/20.Area under the curve between 75 and 85 is = (85-75) * (1/20) = (10/20) = 0.5Area under the curve between 85 and 90 is = (90-85) * (1/20) = (5/20) = 0.25.

+6x 6 −6 3 1
For the function y = 4x^2, it is possible to find the maximum or minimum. the value of y at the maxima/minima of the function y = -3x^2 + 6x is 3.
The function represents a quadratic equation with a positive coefficient (4) in front of the x^2 term. This indicates that the parabola opens upward, which means it has a minimum point.
For the function y = 3x, it is not possible to find the maximum or minimum because it represents a linear equation. Linear equations do not have maxima or minima since they have a constant slope and continue indefinitely.
For the function y = -3x^2 + 6x, we can find the maxima or minima by finding the vertex of the parabola. The vertex can be found using the formula x = -b/(2a), where a and b are coefficients of the quadratic equation.
In this case, the coefficient of x^2 is -3, and the coefficient of x is 6. Plugging these values into the formula, we have:
x = -6 / (2 * -3) = 1
To find the value of y at the vertex, we substitute x = 1 into the equation:
y = -3(1)^2 + 6(1) = -3 + 6 = 3
Therefore, the value of y at the maxima/minima of the function y = -3x^2 + 6x is 3.

(d) Given that n(§) = 96, n(A) = 50 and n(B) = 60. Find the maximum and minimum values for n(An B).
how to get the answer? I want the solution
Step-by-step explanation:
the max. value is when the smaller set (A) is completely contained in the larger set (B).
then n(A n B) is n(A) = 50.
the set intersection between A and B cannot get bigger than that. or A gets bigger ...
after all, the intersection means it is a set of all elements that exist in BOTH sets.
but then there must be other elements besides A and B in the universal set too, because n(universal set) = 96, and n(A u B) would be only 60.
the min. value could be the empty set or 0. but because n(universal set) = 96, and n(A) + n(B) = 110 and larger than 96, it means that there have to be some shared elements. at least 110 - 96 = 14 elements.
in this case there cannot be other elements in the universal set than A and B. and n(universal set) = n(AuB) = 96.

The value of log5(x - 1) + log5(x + 3) - 1 = 0 is x = 1 and x = -3.
What is a logarithm?The logarithm is exponentiation's opposite function in mathematics.
This indicates that the exponent to which b must be raised in order to obtain a number x is the logarithm of x to the base b. For instance, because 100 = 10², the logarithm of 100 in base 10 is 2, or log10 = 2.
Given, log5(x - 1) + log5(x + 3) - 1 = 0.
As log + log b = log(ab).
∴ log5(x - 1) + log5(x + 3) - 1 = 0.
log5{(x - 1)(x + 3)} = 1.
(x - 1))x + 3) = 0. (as any value to the power zero is 1)
x - 1 = 0 Or x + 3 = 0.

5x = 19
Divide both sides by 5
5x/5 = 19/5
x = 19 / 5
