Equation with inversely proportional relation gives answer of the following questions :
1. a. w = k₁ / f b. f =60 ⇒ w = 8
2. a. B = k₂/ y b. y = 5 ⇒ B = 2.08
1. Representation of the formula connecting :
w is inversely proportional to the variable f
a . w ∝ ( 1 / f )
⇒ w = k₁ / f
where k₁ is the constant of proportionality.
When w = 40 , f = 12
40 = k₁ / 12
⇒ k₁ = (40)(12)
⇒ k₁ = 480
b . f = 60
Value of 'w' is equal to :
⇒ w= 480 / 60
⇒ w = 8
2. B is inversely proportional to the variable y
a . B ∝ ( 1 / y )
⇒B = k₂ / y
where k₂ is the constant of proportionality.
When B = 0.8 , y = 13
0.8 = k₂ / 13
⇒ k₂ = (0.8)(13)
⇒ k₂ = 10.4
b . y = 5
⇒ B= 10.4 / 5
⇒ B = 2.08
Therefore, the required values and formula to represents the inversely proportional relation are:
The above question is incomplete, the complete question is :
1. W is inversely proportional to f , When f = 12, w = 40
(a) Find a formula connecting w and f .

a fair six-sided die is tossed 300 times. find the expected value of the sample mean of the values obtained in these 300 tosses (write it up to first decimal place).
The expected value of the sample mean of the values obtained in these 300 tosses is 3.5
300 fair throws of a six-sided die are made.
The expected value of the sample mean of the results acquired from these 300 tosses must be determined.
Six sides make up a dice:
Every side of a fair dice has an equal chance of happening.
Now, each side's likelihood of being present is 1/6.
Now, the sample mean of the values collected in these 300 tosses is predicted to be equal to:
E(x) = Σx P(x =x)
= 1*1/6 + 2*1/6 + 3*1/6 + 4*1/6 + 5*1/6 + 6*1/6
= 1/6 + 2/6 + 3/6 + 4/6 + 5/6 + 6/6
= 1/6 (1+2+3+4+5+6)
= 1/6 (21)
= 21/6
E(x) = 3.5
Hence, the expected value of the sample mean of the values obtained in these 300 tosses is 3.5

Netflix is raising its prices from $15. 99 a month to $17. 99 a month. Mr.
Leone is annoyed and will cancel if this is more than a 20% increase in
the price. Based on this information, will he cancel? Explain.
If Netflix is raising it's prices from $15.99 a month to $17.99 a month , then Mr. Leone will not cancel his subscription because the percent increase is 12.507% .
The old subscription price of the Netflix is = $15.99 ;
the new subscription price of Netflix is = $17.99 ;
the percent increase of Netflix can be calculated by using formula :
⇒ (new price - old price)/old price × 100 ;
substituting the values of Netflix prices ,
we get ;
⇒ (17.99 - 15.99)/15.99 × 100 ;
⇒ 2/15.99 × 100
⇒ 0.12507 × 100 ;

The total number of clients with a BMI of 25.9 or higher is therefore equal to 1 * 2.6 + 3 * 2
The total amount of money she would need to give in discounts next month can be found by calculating the total number of clients with a BMI of 25.9 or higher. To calculate this, the frequencies of each BMI range need to be multiplied by the width of the corresponding bar. The total amount of money she would need to give in discounts is then equal to the total number of clients with a BMI of 25.9 or higher multiplied by $50.
Using the histogram, the number of clients in each BMI range are: 18.1-20.7 (1), 20.7-23.3 (3), 23.3-25.9 (5), 25.9-28.5 (2), 28.5-31.1 (1).

z = 7x/8
Now, the third proportions,
y/30 = z/35
Solving for y,
y = 30z/35
y = 6z/7
x + y + z = 140
4y/3 + 6z/7 + 7x/8 = 140

The amount a tree grows in one month is directly proportional to the amount of water it is given When the tree is given 23 gallons of water, it grows 4 cm that month. What is the constant of proportionality for this variation? Round your answer to the nearest thousandth
The constant of proportionality for this variation is 0.174cm/gallon .
Every relationship that always maintains the same ratio is referred to be proportionality. For instance, the average amount of apples per tree determines the proportionality between both the quantity of apples in a crop and the number of trees in the orchard.
Let the amount a tree grows in one month be - x
The amount of water given be - y
If the amount a tree grows in one month is directly proportional to the amount of water given, then
x ∝ y
x = ky
k is defined as the constant of proportionality
k = [tex]\frac{x}{y}[/tex]

According to the question, the two largest integers are M+2
Let a and b be the two smallest integers such that a<b
Accordingly, the sorted list can be concluded as a,b, M, M+2, M+2
Since the median is 2 greater than their arithmetic mean, we have,
{a+b+M+(M+2)+(M+2)/5 }+2 =M
OR, a+b+14=2M
Note that a+b must be even.
We minimize this sum so that the arithmetic mean, the median, and the unique mode is minimized.

What are the angles of a triangle?The internal angles of a triangle are measured in degrees and are known as triangle angles. The sum of a triangle's angles is always 180°.
Triangle angles are classified into three types: acute angles, right angles, and obtuse angles.
An acute angle is one that is smaller than 90 degrees. This is the most common form of angle in a triangle and is regarded the most desirable.
A right angle is one that is exactly 90 degrees. This sort of angle is the most stable and sturdy in a triangle, therefore it is usually employed to make a triangle.
An obtuse angle is one that is larger than 90 degrees but less than 180 degrees. This form of angle is common in triangles, however it is less desirable than an acute angle.
The sum of the three angles of a triangle is always 180°. Acute angles are the most desirable and stable, whereas obtuse angles are present in certain triangles but are not as ideal.
In the given question,
The measure of the missing angle is 180° - (46° + 73°).
180° - (46° + 73°) = 180° - 119° = 61°

Answer:

Step-by-step explanation:
Think the negative sign outside the parentheses as -1. Then do distributive property to the numbers inside the parentheses.
-1 x 3x and -1 x -12
That equals to -3x + 12 so now your entire equation is -3x + 12 = 9x - 4. Now lets take away 9x from both sides like this,
9x - 9x and -3x - 9x.
That equation is now -12x + 12 = -4.
Now subtract 12 from both sides like this,
12 - 12 and -4 - 12.
And then you have -12x = -16.
Now you divide both numbers by -12 like this,
-12x/-12 which equals to just x and then do -16/-12 which would equal as 1.3333 and repeating but, it can be put as 4/3 for a clearer answer.
