Answer:

I think you must be adding or multiplying each number across.

Step-by-step explanation:

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.

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.

Answer:  There are eight steps and two methods. I will be showing you one of them. If you're wondering, I am in 7th grade. I go to K12 online school.

Step-by-step Explanation: 1. Add together the lengths of the bases. The bases are the 2 sides of the trapezoid that are parallel with one another. If you aren’t given the values for the base lengths, then use a ruler to measure each one. Add the 2 lengths together so you have 1 value.[1]

For example, if you find that the top base (b1) is 8 cm and the bottom base (b2) is 13 cm, the total length of the bases is 21 (8 cm + 13 cm = 21 cm, which reflects the "b = b1 + b2" part of the equation).
2. Measure the height of the trapezoid. The height of the trapezoid is the distance between the parallel bases. Draw a line between the bases, and use a ruler or other measuring device to find the distance. Write the height down so you don’t forget it later in your calculation.[2]

The length of the angled sides, or the legs of the trapezoid, is not the same as the height. The leg length is only the same as the height of the leg is perpendicular to the bases.

3. Multiply the total base length and height together. Take the sum of the base lengths you found (b) and the height (h) and multiply them together. Write the product in the appropriate square units for your problem.[3]

In this example, 21 cm x 7 cm = 147 cm2 which reflects the "(b)h" part of the equation.

4. Multiply the product by ½ to find the area of the trapezoid. You can either multiply the product by ½ or divide the product by 2 to get the final area of the trapezoid since the result will be the same. Make sure you label your final answer in square units.[4]

For this example, 147 cm2 / 2 = 73.5 cm2, which is the area (A).

Answer: The answer is 1200

Explanation: In took the test and it was right

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

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.

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:

— Maria has "such" total bullets, and shared it among 9 friends.

So, the representation in algebra is p ÷ 9

Considering that for each item, there are only two possible outcomes, and the probability of an item being defective is independent of any other item, the binomial distribution is appropriate.

It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.

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

Step-by-step explanation:

I'm not good with explanations but, $1 = 4 quarters, so Emil and Jade

subtracted $1 from each pile and then added $1 to each pile.

Since they subtracted and added the same amounts to each

pile, the piles are equal in value.

Yes, both of them will have the same amount after exchanging the money.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Emil has $1 and a quarter. Jade has 5 quarters. If Emil gives Jade $1 and Jade gives Emil 4 quarters.

The amount can be balanced as below,

$1 = 4 quarters

E + 4 Quarters  = J + $1

E + $1 = J + $1
