Step-by-step explanation:

The total number of ways to distribute all the fruits to the 30 children, ensuring each child who prefers apples gets at least 2 apples and each child who prefers oranges gets at least 2 oranges, is given by the product of C(29, 9) and C(59, 19).

To find the total number of ways, we can consider the distribution of apples and oranges separately. For the children who prefer apples, we need to distribute 20 apples among 10 children, with each child receiving at least 2 apples. This can be calculated using the stars and bars combinatorial technique. Similarly, for the children who prefer oranges, we need to distribute 40 oranges among 20 children, with each child receiving at least 2 oranges.

The number of ways to distribute the apples can be calculated as C(20+10-1, 10-1) = C(29, 9). Likewise, the number of ways to distribute the oranges can be calculated as C(40+20-1, 20-1) = C(59, 19). To find the total number of ways to distribute both fruits, we multiply these two values together.

Therefore, the total number of ways to distribute all the fruits to the 30 children while satisfying the given conditions is C(29, 9) x C(59, 19).

The probability that 5 hearts are chosen when 7 cards are drawn from a well-shuffled deck of 52 playing cards is option (d) 0.00000962.

Step 1: Determine the total number of ways to choose 7 cards from a deck of 52 playing cards, which can be calculated using the combination formula: C(52, 7) = 52! / (7! * (52 - 7)!), where "!" denotes the factorial.

Step 2: Determine the number of ways to choose 5 hearts from the deck. There are 13 hearts in a standard deck, so we can calculate the number of ways to choose 5 hearts from 13: C(13, 5) = 13! / (5! * (13 - 5)!).

Step 3: Calculate the probability by dividing the number of favorable outcomes (choosing 5 hearts) by the total number of possible outcomes (choosing 7 cards from the deck): P(5 hearts) = C(13, 5) / C(52, 7).

Step 4: Evaluate the probability numerically using a calculator or math software, and the result is approximately 0.00000962.

Therefore, the correct answer is option (d) 0.00000962.

To solve the system of equations:

4x - 4y = 24

x - 4y = 3

Multiply the second equation by 4 to get 4x - 16y = 12.

Subtract the first equation from the new equation to eliminate x:

(4x - 16y) - (4x - 4y) = 12 - 24

-12y = -12

Solve for y:

y = 1

Substitute y = 1 into one of the original equations (e.g., x - 4y = 3) to find x:

x - 4(1) = 3

x = 7

Check the solution by substituting x = 7 and y = 1 into both original equations:

4x - 4y = 24 --> 4(7) - 4(1) = 24 (true)

x - 4y = 3 --> 7 - 4(1) = 3 (true)

Therefore, the solution to the system of equations is x = 7 and y = 1.

To find:-

Answer:-

On drawing a figure representing the given situation , we get a right angled triangle . To find out the distance between Barry and Dillon we can use Pythagoras theorem, according to which;

\(\rm\implies h^2=a^2+b^2\\\)

Here h is the longest side and a and b are two other sides. And in this question, hypotenuse is 8ft . One of the other side is 5ft .

On substituting the respective values , we have ;

\(\rm\implies 8^2 = 5^2+a^2 \\\)

\(\rm\implies 64 = 25 + a^2\\\)

\(\rm\implies 64 - 25 = a^2 \\\)

Step 1: Find the second derivative y'' for each function.
(A) y = 2e

-> y'' = 0
(B) y = e^x

-> y'' = e^x
(C) y = sin(2x)

-> y' = 2cos(2x)

We want to find a linear equation that models the given situation.

The solution is p = $0.0001*q - $23

The general linear equation is:

p = m*q + c

Where m is the slope and c is the y-intercept.

If we know that the line passes through two points (x₁, y₁) and (x₂, y₂) then the slope can be written as:

\(m = \frac{y_2 - y_1}{x_2 - x_1}\)

Here we have the two points:

price = $9, boxes = 320,000

price = $8.50, boxes = 270,000

We can rewrite these as:

(320,000 , $9)

(270,000 , $8.50)

Then the slope of the line will be:

\(m = \frac{\$ 9 - \$ 8.50}{320,000 - 270,000} = \$ 0.00001\)

Then the line is something like:

p = $0.0001*q + c

To find the value of c we can use one of the two given points, I will use the first one, (320,000 , $9).

Replacing that in our equation we get:

$9 = $0.0001*320,000 + c  

$9 - $0.0001*320,000  = c = -$23

Then the linear equation is:

p = $0.0001*q - $23

Step-by-step explanation:

The solution set is {(-5 + 3√5)/2, (-5 - 3√5)/2}. These are exact, irrational solutions.

Using the product rule of logarithms, we can combine the two logarithms into a single logarithm:

log3[(x + 4)(x + 1)] = 2

Now, we can rewrite this equation without logarithms:

3^2 = (x + 4)(x + 1)

Expanding the right side:

9 = x^2 + 5x + 4

Bringing everything to one side:

x^2 + 5x - 5 = 0

Using the quadratic formula:

x = (-5 ± √(5^2 - 4(1)(-5))) / (2(1))

x = (-5 ± √45) / 2

Simplifying the radical:

x = (-5 ± 3√5) / 2

So, the solution set is {(-5 + 3√5)/2, (-5 - 3√5)/2}. These are exact, irrational solutions.
