Identify the terms and like terms in the expression.
2n - n - 4 + 7n
Answer:
8n-4
Step-by-step explanation:
2n-n-4+7n
=2n-n+7n-4
=8n-4
The terms are 2n, - n, - 4 and 7n. The like terms are 2n, -n and 7n
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
We are given the expression as
2n-n-4+7n
WE need to solve the problem first then identify.
=2n-n+7n-4
The terms are 2n, - n, - 4 and 7n
The like terms are those which contain same variable with same degree.
2n, -n and 7n
Now solving the like terms we get;
=8n-4
Hence, The terms are 2n, - n, - 4 and 7n. The like terms are 2n, -n and 7n

James is a DJ at local radio station. One day, James offers a cash prize to the first caller who correctly answers a rather difficult trivia question. James’ assistant screens and records all incoming calls, and lets James know when the first call with the correct answer has been received; only then does James air the recording of the caller responding correctly. The probability that a randomly selected caller will correctly answer the trivia question is 0.1.
What is the probability that the third caller is the first to correctly answers the question?
0.01
0.0729
0.081
0.09
0.9
Using the inverse binomial distribution, it is found that there is a 0.081 = 8.1% probability that the third caller is the first to correctly answers the question.
The number of callers that correctly answer the question is a binomial variable, however, we want the probability of the third caller being the first to answer the question correctly, hence it is a negative binomial variable.
Inverse binomial:
It is the number of trials until q successes of a binomial variable, with p probability of success.
The probability mass function is:
[tex]P(X = x) = C_{x+q-1,q-1}(1 - p)^xp^q[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question:
Number of trials until 1 success, hence [tex]q = 1[/tex].0.1 probability of a success on each trial, hence [tex]p = 0.1[/tex].The probability that the third caller is the first to correctly answers the question is P(X = 3), hence:
[tex]P(X = x) = C_{x+q-1,q-1}(1 - p)^xp^q[/tex]
[tex]P(X = 3) = C_{3,0}(0.9)^2(0.1)^1 = 0.081[/tex]
0.081 = 8.1% probability that the third caller is the first to correctly answers the question.

Alyssa is painting 3 of the walls in her art studio blue. Each of the walls is 8.3 feet tall and 7.5 feet wide. Round the length and width to the nearest whole number (ones). Then estimate the area Alyssa will paint. Write equations to show your work.
Answer: below(=
Step-by-step explanation: Given that,
dimensions of wall = 8.3ft by 7.5ft
height of wall = 8.3
width of wall = 7.5
there are total 3 walls in a bedroom to be painted blue.
Formula to calculate area of one wall
Height x Width
Formula to calculate area of four walls
3 (Height x Width)
= 3( 8.3ft x 7.5ft)
= 3 (62.25 ft²)
= 186.75 ft²
So area Alyssa will paint = 186.75 ft²

if side c of a right triangle is called the hypothenuse, what are the other sides called
Answer:
The other sides are called legs.
Step-by-step explanation:
Right Triangles
They are a special type of triangles on which one of its internal angles is 90°. Since the sum of all internal angles is 180°, the sum of the other acute angles is 90°.
The longest side is called the hypotenuse and the other two sides are called legs.
The attached image shows a right triangle of hypotenuse c and legs a and b.
Evaluate p(x)=−3+4x when x=−2,0, and 5.
Answer:
p(-2) = -11
p(0) = -3
p(5) = 17
Step-by-step explanation:
Think of p(x) as a y. Just substitute the x values into the equation, and with some basic algebra, you should get your answer
p(-2) = -3 + (-8) = -11
p(0) = -3 + 0 = -3
p(5) = -3 + 20 = 17

How many solutions does the system of equations have
1. Exactly two
2. Exactly one
3. Infinity many
4. None
Answer:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases.
so the answer to this question is it has infinite solutions
Step-by-step explanation:
two parallel lines go forever
