I cant solve this answer

Step-by-step explanation:

Ex: Twelve of the students in the school choir like to sing solos. These 12 students make up 24% of the choir. How many students are in the choir ?

Write a proportion comparing the percent to the ratio of part to whole.

We know that 12 students represent 24%.

Find the multiplication factor.

Since 12 x 2 = 24, find what number times 2 is equal to 100.

Find the denominator.

12/50  =  24/100

(Since 50 · 2  =  100, the denominator is 50)

Hence, there are 50 students in the choir.

Answer:

The answer is Sometimes True.

Step-by-step explanation:

Radicals are number that have roots (√) .

Irrational are numbers that cannot be written in a form of fraction (a/b) .

I will show you some examples :

√2 × √2 = 2 (rational)

√2 × √5 = √10 (irrational)

Therefore, the products of 2 radicals will sometimes give rational or irrational numbers.

I apologize, I am unable to create tables or upload scanned documents. However, I can assist you in calculating the amount each investor will receive in each year based on the given information.

To calculate the amount received by each investor in each year, we need to follow these steps:

Calculate the total profit earned by the bank in each year by subtracting the loss values from zero.

Year 1: 0 - (-78,000) = 78,000

Year 2: 0 - (-23,000) = 23,000

Year 3: 29,000

Year 4: 63,000

Year 5: 103,500

Calculate the total profit to be distributed among the investors in each year, which is 60% of the total profit earned by the bank.

Year 1: 0.6 * 78,000 = 46,800

Year 2: 0.6 * 23,000 = 13,800

Year 3: 0.6 * 29,000 = 17,400

Year 4: 0.6 * 63,000 = 37,800

Year 5: 0.6 * 103,500 = 62,100

Calculate the profit share for each investor based on their respective share of the investment.

Year 1:

Fahad: (30/100) * 46,800

Yashara: (50/100) * 46,800

Saud: (20/100) * 46,800

Fariha: (40/100) * 46,800

Younus: (25/100) * 46,800

Asif: (35/100) * 46,800

Similarly, calculate the profit share for each investor in the remaining years using the same formula.

By following the calculations above, you can determine the amount each investor will receive in each year based on their share of the investment.

Answer:

Width = 46 yards, Length=175 yards.

Step-by-step explanation:

Perimeter of rectangle = 2(length) +2(width)

We know that the length is 4width-9, so we can substitute that in for the length.

442= 2(4w-9)+2w, Next distribute

442=8w-18+2w, Now add like terms

442=10w-18, Move 18 to the other side

460=10w, solve for w

width= 46 yards.

Now we have 442=2(length)+2(46), subtract 92 to the left

350=2(length), divide by 2

Length= 175 yards.

Check your work with P=2(175)+w(46)

P=442 yards.

The best estimate of the product is b) 1 times 10.

The expression (7/8)8(1/10) can be simplified by canceling out the factor of 8 in the numerator and denominator. This yields the expression 7/10. Therefore, the best estimate of this expression would be 1 times 10, since 7/10 is closest to 1 when rounded to the nearest whole number, and 10 is the closest whole number to the denominator of 7/10.

Thus, the answer is option b, 1 times 10. It is important to note that when estimating products or other mathematical expressions, it is important to consider the context and choose an estimate that is reasonable and makes sense in the given situation.

Correct Question :

Which expression is the best estimate of the product of (7/8)8(1/10)?

Answer: $17.82

Step-by-step explanation: Add each item up to get $19.80. Then you take 10% of that by multiplying it 0.9 to get 17.82. You multiply it by 0.9 because that is 90% of 19.80 which is a 10% decrease.

Answer:

The first derivative of \(r(t) = 5\cdot t^{-2}\) (r(t)=5*t^{-2}) with respect to t is \(r'(t) = -10\cdot t^{-3}\) (r'(t) = -10*t^{-3}).

Step-by-step explanation:

Let be \(r(t) = \frac{5}{t^{2}}\), which can be rewritten as \(r(t) = 5\cdot t^{-2}\). The rule of differentiation for a potential function multiplied by a constant is:

\(\frac{d}{dt}(c \cdot t^{n}) = n\cdot c \cdot t^{n-1}\), \(\forall \,n\neq 0\)

Then,

\(r'(t) = (-2)\cdot 5\cdot t^{-3}\)

\(r'(t) = -10\cdot t^{-3}\) (r'(t) = -10*t^{-3})

The first derivative of \(r(t) = 5\cdot t^{-2}\) (r(t)=5*t^{-2}) with respect to t is \(r'(t) = -10\cdot t^{-3}\) (r'(t) = -10*t^{-3}).

Step-by-step explanation:

The probability that the second card is a jack given that the first card was a 2 is 52/51.

To calculate the probability that the second card is a jack given that the first card was a 2, we need to consider the remaining cards in the deck after the first card is drawn.

When the first card is drawn and it is a 2, there are 51 cards remaining in the deck, out of which there are 4 jacks.

The probability of drawing a jack as the second card, given that the first card was a 2, can be calculated using conditional probability:

P(Second card is a jack | First card is a 2) = P(Second card is a jack and First card is a 2) / P(First card is a 2)

Since the first card is already known to be a 2, the probability of the second card being a jack and the first card being a 2 is simply the probability of drawing a jack from the remaining 51 cards, which is 4/51.

The probability of the first card being a 2 is simply the probability of drawing a 2 from the initial deck, which is 4/52.

P(Second card is a jack | First card is a 2) = (4/51) / (4/52)

Simplifying the expression:

P(Second card is a jack | First card is a 2) = (4/51) * (52/4)

P(Second card is a jack | First card is a 2) = 52/51

a) The solution to the recurrence relation is an = [(1 + √2)/4](2 + 2√2)^n + [(1 - √2)/4](2 - 2√2)^n.  (b) The solution to the recurrence relation is an = -2·2^n + 3·2^n = 2^n(3 - 2^n).

(a) The characteristic equation of the recurrence relationan = 4an−1 + 4an−2 is r^2 - 4r - 4 = 0. Solving this quadratic equation, we get r = 2 ± 2√2. Therefore, the general solution of the recurrence relation is an = c1(2 + 2√2)^n + c2(2 - 2√2)^n. Using the initial conditions a0 = 1 and a1 = 2, we can solve for the constants c1 and c2. We get c1 = (1 + √2)/4 and c2 = (1 - √2)/4. Therefore, the solution to the recurrence relation is an = [(1 + √2)/4](2 + 2√2)^n + [(1 - √2)/4](2 - 2√2)^n.

(b) The homogeneous part of the recurrence relationan = 2an−1 is given by the characteristic equation r - 2 = 0, which has the root r = 2. Therefore, the general solution of the homogeneous part is an = c2·2^n. To find a particular solution of the non-homogeneous part an = 3 · 2^n, we can try the form an = A·2^n. Substituting this into the recurrence relation, we get A·2^n = 3·2^n, which implies A = 3. Therefore, a particular solution of the non-homogeneous part is an = 3·2^n. The general solution of the recurrence relation is the sum of the homogeneous and non-homogeneous parts, which is an = c2·2^n + 3·2^n. Using the initial condition a0 = 1, we get c2 = 1 - 3 = -2. Therefore, the solution to the recurrence relation is an = -2·2^n + 3·2^n = 2^n(3 - 2^n).

We may build up a proportion and solve for the scale model radius of Neptune using the ratio between the radii of the two planets and the known scale model radius of the Earth. The scale model of Neptune that is produced has a radius of around 9.7 cm.

We may take advantage of the fact that the ratio between the two planets' radii and the ratio between their respective scale model radii is the same. Let's name the Neptune scale model radius "r" Then, we may set up the ratio shown below:

Neptune's radius is equal to the product of Earth's radius and its scale model.

With the provided values, we may simplify and obtain:

24620 km / 6370 km equals 2.5 cm / r

We obtain the following when solving for "r":

r = (24620 km * 2.5 cm) / (6370 km)

r ≈ 9.7 cm

Therefore, a scale model of Neptune would have to be drawn with a radius of approximately 9.7 cm.

The equation to model the population is P = \(\frac{1}{40}\) \(e^{0.05t}\) + 30

Here the population P of a small town, measured in hundreds, is modeled by the inverse of the function,P−1(t) = 20ln(40t − 1200)

where t is measured in years.

We need to find an equation to model the population.

let y = \(p^{-1}\)(t)

where t is measured in years.

We need to find an equation to model the population.

20\(ln\)(40y - 1200) = t

\(ln\)(40y - 1200) = t/20

\(e^{ln(40y - 1200)}\) = \(e^{0.05t}\)

(40y - 1200) = \(e^{0.05t}\)

40y = \(e^{0.05t}\) + 1200

y = \(\frac{1}{40}\) \(e^{0.05t}\) + 30

Now, we determine the initial value.

P(0) = \(\frac{1}{40}\) + 30
