So in this case f(x) is number of pollinated flowers and x is the days. First you will need to determine the number of flowers pollinated at days 4 and 10 and the days in between.  f(4)= 3(4^2)= 3*16 = 48  f(5)= 3(5^2)= 3*25 =75  f(6)= 3(6^2)=3*36=108  f(7)= 3(7^2)=3*49=147  f(8)= 3(8^2)=3*64=192  f(9)= 3(9^2)= 3*81=243  f(10)= 3(10^2)=3*100=300    Now we need to find the average increase, so that will be the average of the differences between days  [(75-48)+(108-75)+(147-108)+(192-147)+(243-192)+(300-243)]/6  =(27+33+39+45+51+57)/6=42

Using the binomial distribution, it is found that there is a 0.2617 = 26.17% probability that at least 8 but at most 10 students will complete their assignments before the due date.

For each student, there are only two possible outcomes, either they complete the assignment, or they do not. The probability of a student completing the assignment is independent of any other student, hence the binomial distribution is used to solve this question.

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem:

The probability is:

[tex]P(X \geq 8) = P(X = 8) + P(X = 9) + P(X = 10)[/tex]

In which:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 8) = C_{10,8}.(0.65)^{8}.(0.35)^{2} = 0.1757[/tex]

[tex]P(X = 9) = C_{10,9}.(0.65)^{9}.(0.35)^{1} = 0.0725[/tex]

[tex]P(X = 10) = C_{10,10}.(0.65)^{10}.(0.35)^{0} = 0.0135[/tex]

Then:

[tex]P(X \geq 8) = P(X = 8) + P(X = 9) + P(X = 10) = 0.1757 + 0.0725 + 0.0135 = 0.2617[/tex]

0.2617 = 26.17% probability that at least 8 but at most 10 students will complete their assignments before the due date.

Answer:

  (x, y, z) = (3, -2, 4)

Step-by-step explanation:

The attachment shows a solution using a graphing calculator where the first equation is solved for z, and that expression is substituted into each of the other two equations. The solution to that system is (x, y) = (3, -2). Using these values in the expression for z, we find ...

  z = 5 -(3 +(-2)) = 4

The solution is (x, y, z) = (3, -2, 4).

__

Your graphing calculator and/or online tools can give you the reduced row echelon form of the augmented matrix representing the system:

  [tex]\left[\begin{array}{ccc|c}1&1&1&5\\-3&-4&4&15\\2&-1&-4&-8\end{array}\right][/tex]

__

If you're solving by hand, you can do the substitution described above to eliminate z from one equation. You can eliminate z from another equation by adding the last two:

  -3x -4y +4(5 -x -y) = 15   ⇒   -7x -8y = -5

  (-3x -4y +4z) +(2x -y -4z) = (15) +(-8)   ⇒   -x -5y = 7

This pair of equations can be solved for x and y in any of the usual ways. Using the second equation to substitute for x, for example, gives you ...

  -7(-5y -7) -8y = -5   ⇒   27y = -54   ⇒   y = -2

  x = -5(-2) -7 = 3

  z = 5 -(3) -(-2) = 4

Additional comment

If all that is needed is a solution, we prefer a graphical or matrix approach. These take about the same amount of time. Both require a little additional effort to determine exact values when the solutions are not integers.

Answer:

(x - 5)(y + 6)

Step-by-step explanation:

Hello!

Let's see. Over here we have two sides of an equation with blank space on the right-hand side. It seems that the topic of the question is factoring.

On the left-hand side, we see that 1 factor is common between two other factors (x and -5). To simplify, we can simply add the two values.

x(y + 6) - 5(y - 6) would be the same as (x-5)(y-6) => your answer

We can check if our equation is true.

x( y + 6) - 5(y + 6) = (x-5)(y + 6)

xy + 6x - 5y -30 = xy - 5y + 6x - 30

xy + 6x - 5y - 30 = xy + 6 - 5y - 30

Both equations are the same

The algebraic expression is p/9

Step-by-step explanation:

Algebraic expression is a mathematical sentence involving numbers followed by letters. An algebraic is also involved in an equation of the first degree, because the unknown or variable is a letter.

This question asks us to form a sentence for this expression. So the sentence could be:

The solution to the equation 1/2 - x + 3/2 = x - 4 is x = 3.

We have Equation 1/2 - x + 3/2 = x - 4

Now, solving the equation for x we get

/2 - x + 3/2 = x - 4

First, let's combine the like terms on both sides of the equation:

(1/2 + 3/2) - x = x - 4

4/2 - x = x - 4

2 - x = x - 4

Next, let's move the term with x to the left side by adding x to both sides:

2 - x + x = x - 4 + x

2 = 2x - 4

Then, let's move the constant term -4 to the right side by adding 4 to both sides:

2 + 4 = 2x - 4 + 4

6 = 2x

6/2 = 2x/2

3 = x

Therefore, the solution to the equation is x = 3.
