Let yyy represent the area (in square meters) left to paint after xxx hours. Complete the equation for the relationship between the area and number of hours.

Answer:

-1/32

Step-by-step explanation:

we have

[tex](-\frac{1}{2})^{3} )(-\frac{1}{2})^{2})[/tex]

Remember that

The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents

so

[tex](-\frac{1}{2})^{3} )(-\frac{1}{2})^{2})=(-\frac{1}{2})^{3+2})=(-\frac{1}{2})^{5})=-\frac{1}{32}[/tex]

Answer:

She will arrive at 3:23 to the pool.

Step-by-step explanation:

Since Natasha takes 33 minutes to walk through the pool from her house.

Also, if she rides a bike then that time is 1/3 times reduced.

So total time to ride the bike from her house to the pool is [tex]33\times\frac{1}{3}=11 minutes[/tex]

Now, If she leaves the house at 3:12 then she will reach to the pool is 3 hours 12 minutes + 11 minutes = 3 hours 23 minutes = 3:13

Hence, She will arrive pool at 3:23.

The length of the rectangle is 21 inches, the width of the rectangle is 10.5 inches

Step-by-step explanation:

Let x inches be the length of the rectangle, then the width of the rectangle is [tex]\dfrac{1}{2}x[/tex] inches.

The perimeter of the rectangle is the sum of all sides' lengths:

Answer:

50 pens

Step-by-step explanation:

x= 25 percent of 200

25/100 times X/200

Cross multiply them and you get

100x=5000

X=5000/100

X=50

25 percent of 200 is 50.

Which means they have away 50 pens

So this number is going to be a seven-digit number, and in the ones place, there will be a 0, giving us ?.???.??0. When a 6 is in the ten thousands place and the 8 in the millions place, it would be 8,?6?,??0. Now the rest of the places that are missing a number is going to be five, which is 8,565,550. The answer is 8,565,550.

Answer:

b) x ≥ 3000 gallons

Step-by-step explanation:

Part a)

Production of Year 1 = x gallons

By each year the producer will increase the production by 500 gallons. So,

Production in Year 2 = x + 500 gallons

Similarly,

Production in Year 3 = x + 500 + 500 = x + 1000 gallons

Production in Year 4 = x + 1000 + 500 = x + 1500 gallons

Production in Year 5 = x + 1500 + 500 = x + 2000 gallons

Part b)

The maple syrup producer wants to produced atleast 20,000 gallons in 5 years.

Total amount produced in 5 years = x + x + 500 + x + 1000 + x + 1500 + x + 2000

Total amount produced in 5 years = 5x + 5000

Since, producer wants total production to be atleast 20,000, we can set up the inequality as:

5x + 5000 ≥ 20000

Subtracting 5000 from both sides, we get:

5x ≥ 15000

Dividing both sides by 5, we get:

x ≥ 3000

This means, in the first year the production of maple syrup must be atleast 3,000 gallons i.e 3000 gallons or more to have a total of atleast 20,000 gallons in 5 years.

Answer: C

Step-by-step explanation: C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

Total: 1000

20 had fever, so 1000 - 20 = 980 who did not have fever

Total who did not have fever: 980

As 880 not fever and not inflamation, 980 - 880 = 100

So, 100 had inflamation but not fever.

  11/7 ≠ 13/8 ≠ 15/9 ≠ 17/10

Answer:

Step-by-step explanation:

Use the Compound Amount equation:  A = P(1+r/n)^(nt), where P is the original amount (principal), r is the interest rate as a decimal fraction, n is the number of compounding periods per year, and t is the number of years.  Here we have:

A = ($2665.79)(1 + 0.048/4)^(4*11), or:

A = ($2665.79)(1.012)^44 = $4505.76.

Subtracting the principal amount from this result, we get:

$4505.76 - $2665.79 = $1839.97

This matches the third of the four given possible answers.

Final answer:

To calculate the interest earned, use the formula for compound interest: CI = P(1 + r/n)^(nt) - P. Plugging in the given values, the interest earned by Nelson is $1,839.97.

Explanation:

To calculate the interest earned, we can use the formula for compound interest:

CI = P(1 + r/n)^(nt) - P

Where CI is the compound interest, P is the principal amount, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years.

Plugging in the given values, we have:

CI = 2665.79(1 + 0.048/4)^(4*11) - 2665.79

Calculating this, we find that the interest earned is $1,839.97.

Answer:

This is actually an interview question for IT jobs!

The game strategy changes if there can be communication or not.

If there is no communication then I would pick the expected value of the game, meaning the sum of each value times the probability of it showing up on the die (1/21) or:

[tex]E(x) = 1*\frac{1}{21} +2*\frac{1}{21}+3*\frac{1}{21}+...+21*\frac{1}{21}[/tex]=[tex]\frac{231}{21} =11[/tex]

This mathematically minimizes the difference between my pick and the one that comes from the roll.

If there is communication, and a consensus can be reached, then the most reasonable answer would be the one that gives all of us the same possibility to win: 4, 11, 18, so each of us covers 7 numbers, and each of us would have 1/3 chances to win.

If there is communication, and a consensus cannot be reached, then I would have to calculate the difference between both their pics, if it is smaller than the expected value, and it inclines towards high numbers, for example: 10, 18, then i would pick one less than the smallest, meaning 9, because i would cover 1-9, the one picking 10 would cover 10-14 and 18 would cover 15-21. My range would be bigger. If it is smaller than the expected value, and it inclines towards low numbers, i would pick one over the highest, for example 4, 9. I would pick 10. If the difference is bigger than  the expected value then i would calculate whether i would cover more picking a number in the middle of their range or to the side, depending on their pick. For example, if they pick 9, 21, I would cover more range picking 8 than 15.

To maximize odds of winning in a game with a 21-faced die, choose a number in the middle range, such as 11, or strategically select a number that evenly splits the range of possible outcomes, taking into account the numbers chosen by other players.

The best strategy for choosing a number in a game with a 21-faced die is to select a number that lies in the middle range, as this increases the probability that your number will be closest to the outcome of the roll. With a 21-faced die, the middle number is 11. Assuming other players may not choose the same number, if you pick first, go for 11. If other players have already picked numbers, choose a number that splits the remaining range of outcomes as evenly as possible. This method leverages the concept of probability which, unlike games of pure luck like roulette, gives you some control as you can make educated guesses based on the remaining numbers, just as skill is involved in games like blackjack where decisions are critical to the outcome.

In gambling games like blackjack, skillful play can reduce the house edge whereas in roulette, every spin is independent of the last. The outcomes of particular numbers being rolled in a dice game can inform your strategy to some extent - for example, knowing that seven is the most common result when rolling two six-sided dice because there are more combinations that produce this sum. However, with a single die, as in the scenario with the 21-sided die, each face has an equal probability of landing face up, so strategic choice becomes more about distancing your choice from others to maximize your chances of being closest to the roll's outcome.

To find a possible value for n given the number of squares not along the boundary of a gameboard, set up an equation and solve it using the quadratic formula.

The number of squares that do not lie along the boundary of the gameboard can be found by subtracting the number of squares along the boundary from the total number of squares on the gameboard. The total number of squares on the gameboard is n×n, and since there are n squares along each side of the gameboard, the number of squares along the boundary is 4n. Therefore, the number of squares that do not lie along the boundary is n×n - 4n.

Given these equations, we can set up an equation for each possible value of k:

We can solve these equations to find the possible values of n. For the first equation, arranging the terms gives us the quadratic equation n×n - 4n - 10 = 0. By solving this quadratic equation using the quadratic formula, we can find the possible values of n that satisfy the equation. Similarly, we can do the same for the remaining equations to find all possible values of n.

This amount can be added or subtracted from the nominal length, so the range of lengths is ...

Answer:

  0.0001

Step-by-step explanation:

The value of the number is 0.0001. That presentation meets the format requirements for your literal.

To express 1.0e-4 as a floating-point literal in long form without scientific notation, write it as 0.0001, which means moving the decimal four places to the left.

To type 1.0e-4 as a floating-point literal with a single digit before and four digits after the decimal point without using scientific notation, we need to convert the exponent to its decimal representation. The exponent “e-4” indicates that the decimal point is to be moved 4 places to the left.

The number 1.0e-4 in long form is 0.0001. This is because the exponent part “e-4” of the scientific notation corresponds to dividing the number by 10,000 (which is 10⁴), turning 1 into 0.0001. To express this number with one digit before the decimal point and four digits after, we write it as 0.0001.

When converting from scientific notation or using significant figures, remember that all digits reported in front of the multiplication sign are significant, zero functions as a placeholder for the decimal point, and negative exponents indicate division by powers of ten.

# If the inequality is x > a, then it represented on the number line by

  a ray with empty small circle as end starts at a and pointed to

  the right (⇒ ∞)

# If the inequality is x ≥ a, then it represented on the number line by

Answer: There is 58.3% of students that are not convinced.

Step-by-step explanation:

Since we have given that

Number of schools = 300

Number of schools that are convinced to sell their products = 125

Number of schools that are not convinced to sell their products = 300 - 125 = 175

Percentage of schools that are not convinced is given by

(175 ÷ 300) × 100

= 175 ÷ 3

= 58.3 %

Hence, there is 58.3% of students that are not convinced.

Answer:

d. empirical discrete distribution

Step-by-step explanation:

Empirical refers to what you observe, in this case the relative frequency

Discrete probability distributions is what you are trying to develop.

a, b and c are different forms an empirical discrete distribution can take. You could say that a,b and c are "types" of the "empirical discrete distribution"

The use of the relative frequency method leads to an empirical discrete distribution, which reflects observed frequencies in a sample and is distinct from theoretical models like the binomial distribution.

The use of the relative frequency method to develop discrete probability distributions leads to what is known as an empirical discrete distribution. This method involves determining probabilities based on the frequency of observed outcomes in a sample. In contrast, other discrete distributions such as the binomial distribution, hypergeometric distribution, and Poisson distribution are based on mathematical models with specific properties and assumptions beyond empirical observation.

An empirical discrete distribution captures the observed frequencies of outcomes in a sample and uses these frequencies as probabilities. It does not assume a specific theoretical distribution model, unlike the uniform distribution which assumes each outcome is equally likely, or the binomial distribution which is based on a fixed number of independent trials with a constant probability of success.

Answer:

this is not a function because the 2 is used twice

Answer: "D"

Step-by-step explanation: The mapping diagram shown here would not represent a function. When looking at a mapping diagram, there is one key thing we need to look for to identity if the relation is a function. We need to look and see if an input has two different outputs. When looking at the mapping diagram, the input (2) has two completely different outputs which makes this hard to interpret data. This means that the relation is not a function.

When dealing with mapping diagrams, remember that an input can only have one corresponding output and if it has more than one, then this would not represent a function.  

Answer:

for year 1

common stock =  $1.75 per share

preferred stock  = Zero

for year 2

common stock =  $4.25 per share

preferred stock  = $0.3 per share

for year 3

common stock =   $3 per share

preferred stock  =  $2 per share

Step-by-step explanation:

step 1

preferred stock value =  (40000 shares * $150) = $6000000

common stock value  = (100000 shares * $5) = $500000

 step 2

For year 1:

Dividend on preferred stock;

[tex]\frac{6000000 * 2}{100}[/tex] = $120000

But total dividend in the question was $70000 therefore total amount of  dividend on cumulative preferred stock is $70000.

hence, dividend per share

[tex]= \frac{70000}{40000 shares}[/tex] = $1.75 per share

Dividend on common stock;

70,000 - 70,000 = Zero

as total dividend distributed in year 1 is insufficient for cumulative preferred stock therefore no dividend will be paid on common stock.

For year 2:

Dividend on cumulative preferred stock;

[tex]\frac{6000000 * 2}{100}[/tex]= $120000

extra dividend of year 1 ($120000 - $70000) = $50000

Thus total dividend on cumulative preferred stock

($120000 + $50000) = $170000

So dividend per share

[tex]\frac{170000}{40000\ shares}[/tex]= $4.25 per share

Dividend on common stock;

($200000 – $170000) = $30000

dividend per share

[tex]\frac{30000}{100000\ shares}[/tex] = $0.3 per share

For year 3:

Dividend on cumulative preferred stock;

[tex]\frac{6000000 * 2}{100}[/tex] = $120000

total dividend on cumulative preferred stock $120000

dividend per share

[tex] \frac{120000}{40000 shares}[/tex] = $3 per share

No dividend was extra in the year 2 therefore only available dividend of this year will be paid.

Dividend on common stock;

($320000 – $120000) = $200000

dividend per share

[tex]\frac{200000}{100000\ shares}[/tex]= $2 per share
