Answer: 22.4402

Step-by-step explanation:

Answer:

84.4% of 23 is 19.412.

Step-by-step explanation:

Let the unknown number be x.

Now, 84.4% of x = 19.412.

∴ (84.4 ÷ 100) × x = 19.412.

By simplifying the equation,

x = (19.412 × 100) ÷ 84.4

x = 1941.2 ÷ 84.4

∴ x = 23

Thus, 84.4% of 23 is 19.412.

Area of triangle = 1-2 x base x height

Area = 1/2 x 27 x 16

Area = 216 square units

It is easiest to solve this system by elimination.

4x-8y=44

(2x+4y=-6) -2    ----> multiply the second equation by -2 to create equations where the x coefficients are opposites

     4x-8y=44

(+) -4x-8y=12

-16y=56

y = -7/2

now substitute the value of y into one of the above equations and solve for x

4x – 8(-7/2) = 44

4x + 28 = 44

4x = 16

X = 4

So, the solution is (4, -7/2)

The solution of the  system of equations 4x-8y=44 and 2x+4y=-6is (4, -3.5).

Two or more expressions with an Equal sign is called as Equation.

The given system of equation is 4x-8y=44 ...(1)

and 2x+4y=-6...(2)

To eliminate y term we have to multiply equation 2 with 2.

4x+8y=-12..(3)

Now add equation 1 and 3.

4x-8y+4x+8y=44-12

8x=32

Divide both sides by 8

x=4

Now plug in x value in equation 1

4(4)-8y=44

16-8y=44

Subtract 16 from both sides

-8y=44-16

-8y=28

Divide both sides by 8

y=-28/8

y=-7/2

=-3.5

Answer:

Answer:

12 hours

Step-by-step explanation:

Let w = Wilma alone

Let k = Kyle alone

Let t = Working together

Given the following data;

Time it took Wilma = 4 hours

Time it took them together = 3 hours

Time it took Kyle = x

To find the time it will take Kyle, we would use this arithmetical expression;

\( \frac {1}{w} + \frac {1}{k} = \frac {1}{t}\)

Substituting into the equation, we have;

\( \frac {1}{4} + \frac {1}{x} = \frac {1}{3}\)  

Lowest common denominator (LCD) = 12x

Multiplying all through by "12x" we have;

\( 12x * \frac {1}{4} + 12x * \frac {1}{x} = 12x * \frac {1}{3}\)

Simplifying the equation, we have;

\( 3x + 12 = 4x\)

Rearranging the equation, we have;

\( 4x - 3x = 12\)

x = 12 hours.

Therefore, it would take Kyle 12 hours to mow if he worked alone.

Answer:

  a. $9,090.91

  b. $10,526.32

Step-by-step explanation:

You want to know the value of your $10,000 savings when the price level (a) increases by 10%, and (b) decreases by 5%.

As the price level goes up, the number of items that can be purchased with a given dollar amount goes down in inverse proportion.

When the price level increases by 10%, it is multiplied by 1 +10% = 1.10. The effective purchasing power of the savings will be inversely proportional to that:

  $10,000/1.10 = $9,090.91 . . . "real value" of savings

When the price level decreases by 5%, it is multiplied by 1 -5% = 0.95. The effective purchasing power of the savings will be inversely proportional, so will be ...

  $10,000/0.95 = $10,526.32 . . . "real value" of savings

__

Additional comment

The price level index is usually normalized to a value of 100 at some specified point in time. An increase of 10% in price level would be reflected in an index value of 100×1.10 = 110. Effectively, this means that what did cost $100 at the reference time now costs $110.

With $10,000, you could have purchased 100 of those items, but now you can purchase only 90.91 of those items. Your purchasing power has changed in inverse proportion to the price level.

For the entire year, $9091 will be spent if prices rise by 10%.

In the event that prices drop by 5% for the entire year, $10,526.32

Integers include zero, a positive natural number, and a negative integer represented by a minus sign. The negative numbers are the inverse additions of the comparable positive numbers.

Given,

If the price index is 100, savings equal $10,000.

a) If prices increase by 10% annually, the following formula will be used to calculate the true value of the savings:

Real Value = Nominal Value x Prior Year CPI / Current Year CPI

According to the CPI:

= 100 + (100 x 10/100)

For the current year, = 110%.

The resultant value will be

= $10000 x 100/110

= $9090.90

b) If prices decline by 5% annually, the following formula will be used to calculate the true value of the savings:

Real Value = Nominal Value x Prior Year CPI / Current Year CPI

According to the CPI:

= 100 - (100 x 5/100)

for the current year, = 95%

Consequently, the true value will be:

= $10000 x 100/95

=$10,526.32

As a result, your savings would actually be worth $9090.90 if prices rose by 10% annually.

Alternatively, if prices fall by 5% over the course of the year, the actual worth of your savings is $10,526.32.

The similarities between matrix factorization and content-based filtering and/or collaborative filtering are given below.

What is matrix factorization and collaborative filtering?

A group of cooperative filtering algorithms used in recommender systems is called matrix factorization. The user-item interaction matrix is broken down into the product of two rectangular matrices with lower dimensions by matrix factorization algorithms.

Collaborative filtering makes recommendations by simultaneously comparing similarities between users and items, addressing some of the drawbacks of content-based filtering.

collaborative filtering: user-based for example, CF calculates users' similarities in the item space. Then taking similar users's interest to do a recommendation for the target user. CF is one case of neighborhood methods.

matrix factorization amounts to mapping features of user and item via linear combination to latent factor space respectively.

Then calculating the similarity via inner-product of latent user factor and latent item factor.

CF covers local information of target user for the sake of neighborhood methods, while MF covers global information.

Therefore, a)= (x^ n+ y^ n) is bounded.
b)  limn→ ∞ I n f (x^ n+ y^ n)  ≥  limn→ ∞ I n f(x ^ n)+  limn→ ∞ I n f(y^ n)                                          

Step-by-step explanation:

a) Let (x^ n) and (Y^ n) be bounded sequences, so
∃M>0 such that |x^ n|≤ M ∀n ∈ N
∃M>0 such that |Y^ n|≤ M ∀n ∈ N

Consider
|x^ n| ≤ |x^ n|+|Y^ n|
≤M +M'
=P          (Take p=M+M'>0)

Thus, |x^ n + y^ n|≤p,  ∀n ∈ N.
Therefore, (x^ n+ y^ n) is bounded.


b) Let (x) be a bounded sequence so ( x^ n) is bounded below by k.
Then for each n ∈ N, the set x^ n=(x^ n,x^n+1,....) is bounded below by k.
By completeness axion X^ n has infimum m^ n and the sequence (m^ n) being a increasing sequence is either convergent or divergent to ∞
If(m^ n) is convergent then limn→ ∞m^ n is called the limit infimum of (x^ n).

Thus, limn→ ∞I n f( x^ n)=limn→ ∞ I n f (x^ n,x^n+1,...)
∴
Similarly, m'^ n=I n f (y^ n, y^ n+1...)
Consider
I n f (x^ n+ y^ n, x^n+1 +y^n+1..) ≥ I n f (x^ n, x^ n+1...)+I n f ( y^ n, y^ n+1..)
I n f(x^ n+ y^ n, x^n+1 +y^n+1...) ≥ m^ n+ m'^ n
We have
= limn→ ∞ I n f (x^ n+ y^ n)= limn→ ∞ ( x^ n +y^ n, x^n+1 +y^n+1...)
=≥ limn→ ∞(m^ n+ m')
= limn→ ∞m^ n+ limn→ ∞m'^ n
= limn→ ∞ I n f (x^ n) + limn→ ∞ I n f (y^ n)
∴Therefore
 limn→ ∞ I n f (x^ n+ y^ n)  ≥ limn→ ∞ I n f(x ^ n)+  limn→ ∞ I n f(y^ n)

Isabella's possible numbers can be represented by the compound inequality 15 ≤ 5n - 5 ≤ 50, which in interval notation is [4, 11].

Based on the given information, we can set up a compound inequality to represent the range of numbers that Isabella might be thinking of.

Let's denote the number Isabella is thinking of as 'n'.

The clue states that "5 less than 5 times his number is at least 15 and at most 50."

We can express this as:

15 ≤ 5n - 5 ≤ 50

To solve this compound inequality, we add 5 to all three parts of the inequality:

15 + 5 ≤ 5n - 5 + 5 ≤ 50 + 5

20 ≤ 5n ≤ 55

Finally, dividing all parts of the inequality by 5:

20/5 ≤ n ≤ 55/5

4 ≤ n ≤ 11

Therefore, Isabella's number, 'n', lies in the range [4, 11] in interval notation. In summary, the compound inequality 15 ≤ 5n - 5 ≤ 50 represents the range of numbers that Isabella might be thinking of. The interval notation [4, 11] indicates that her number could be any value between 4 and 11, inclusive.

The statement that if the standard deviation of a data set is zero, then all entries in the data must equal zero is false. The standard deviation of a data set measures the spread of the data around the mean. If the standard deviation is zero, then this means that all of the data values are equal to the mean, but it does not necessarily mean that all of the data values are zero.
