A binomial expression is of the form (x + y)ⁿ. The given binomial expression (2x + 3)⁵ has 6 terms in it.
Binomial is said to be the algebraic expression containing exactly two terms.
Examples of binomials are 4x² + 5y², xy² + xy, x + y, x² + 3, etc.
The number of terms in the binomial expression (x + y)ⁿ is given as,
Number of terms = n + 1
where, n is the power of ( x + y )
In the above given binomial expression, (2x + 3)⁵, n = 5.
N = n + 1 = 5 + 1 = 6
Thus, there are a total of 6 terms in the above expansion.

Now, suppose assuming the true fraction of voters is .65, the estimated standard deviation of X is given as 6.65. Suppose you find that 115 people actually voted yes in the random sample of 200. Conduct hypothesis testing using p value approach at 5% significance level to determine the validity of Candidate A’s claim that he was at least supported by 65% of the voters. (Make sure you show the steps of hypothesis testing)
Answer:
reject H0 ; conclude that there is significant evidence to conclude that candidate A is supported by less than 65% voters
Step-by-step explanation:
x = 115
n = 200
Phat = x / n = 115 / 200 = 0.575
H0 : P0 ≥ 0.65
H1 : P0 < 0.65
TEST STATISTIC :
Phat - P0 ÷ sqrt[(P0(1-P0))/n]
0.575 - 0.65 ÷ sqrt[(0.65(0.35))/200]
-0.075 ÷ 0.0337268
Test statistic -2.237
Pvalue :
P(Z < - 2.237) = 0.012643
α = 0.05
Pvalue < α
0.012643 < 0.05 ; We reject H0
We can conclude that there is significant evidence to conclude that candidate A is supported by less than 65% voters

brian, tim and kenny got paid a total of $240 for mowing neighborhood lawns . They split the money in the ratio of 5:9:10 . how much money did each boy make . PLEAEEEE SHOW THE work i’m really struggling rn
Answer:
$50 for Brian
$90 for Tim
$100 for Kenny
Step-by-step explanation:
Let 5x = amt for Brian
9x = amt for tim
10x = amt for ken
5x + 9x + 10x = 240
24x = 240
x = 10
5x = 5(10) = $50 for Brian
9x = 9(10) = $90 for Tim
10x = 10(10) = $100 for Kenny
Answer:
Step-by-step explanation:
5x + 9x + 10x = $240
x = $10
Brian got 5x = $50
Tim got 9x = $90
Kenny got 10x = $100

Find Q, I'm not sure if it is possible however.
9514 1404 393
Answer:
Q ≈ 0.0314148930589 radians ≈ 1.79994078613°
Step-by-step explanation:
There is no algebraic solution for the set of equations with mixed polynomial and trig functions:
x·sin(Q/2) = 5
1/2x^2(Q -sin(Q)) = π/12
__
However, we can use the first equation to substitute for x in the second equation. This gives ...
[tex]\displaystyle \frac{1}{2}\left(\frac{5}{\sin{\frac{Q}{2}}}\right)^2(Q-\sin{Q})=\frac{\pi}{12}[/tex]
This can be simplified using the half-angle identity and recast as a function of Q:
[tex]\displaystyle f(Q)=\frac{25(Q-\sin{Q})}{1-\cos{Q}}-\frac{\pi}{12}[/tex]
This function will have a zero at the desired value of Q. It can be solved iteratively. A graph shows an approximate value of Q is 0.314 (radians). The value can be refined by Newton's method iteration to give the angle to full calculator precision:
Q ≈ 0.0314148930589 radians ≈ 1.79994078613°
__
The corresponding value of x is about 318.333447755. In short, this is a very narrow sector/segment in a relatively large circle.

I REALLY NEED BRAINLIEST!!
I think it is 65 hope this helps and i ne
Step-by-step explanation:
Answer: okay so this is a long process
Step-by-step explanation:
the measure of angle N is 65 degrees because when calculating the angle, it is always half of the arc it makes. K is 30 because the arc it makes is 60 degrees and half of 60 is 30. Y is 45 because half of 90 is 45. All of the inside angles of a triangle add up too 180 degrees. So add 30 to 45 and you would get 75, then subtract 75 from 180 to get 105. So the measure of KNY is 105 degrees.
What should be done first to evaluate the expression?
6 + 8 ÷ 4 + (4 × 5)²
Answer:
First, follow the first step in PEMDAS so you would do the parenthesis first followed by exponents, multiplication, division, addition, then subtraction
Step-by-step explanation:
6 + 8 ÷ 4 (4*5)^2
6 + 8 ÷ 4 + 20^2
6 + 8 ÷ 4 + 400
6 + 2 + 400
= 408

What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that the slope is 4 and the line is passing through the point (-1,3).
The y-intercept will be calculated as,
y = mx + c
3 = 4 x -1 + c
c = 7
The equation can be written as,
y = mx + c
y= 4x + 7

Target pays $14.00 for each Halo 4 video game. The selling price is $22.00. What is the percent of markup? Round your answer to the percent.
Answer:
57%
Step-by-step explanation:
Find the markup percent by dividing the difference in price by the original price, and multiplying it by 100
(8/14) x 100
= 57
So, the percent markup is approximately 57%
What is the domain of the relation? On a coordinate plane, a graph of an image has 3 connected lines. The first line goes from (negative 4, negative 4) to (negative 2, 1). The second line goes from (negative 2, 1) to (1, 1). The third line goes from (1, 1) to (6, 4). There are closed circles at (negative 4, negative 4) and (6, 4).
Given:
The graph of a relation contains three lines.
The first line goes from (-4,-4) to (-2, 1).
The second line goes from (-2, 1) to (1, 1).
The third line goes from (1, 1) to (6, 4).
There are closed circles at (-4,-4) and (6, 4).
To find:
The domain of the relation.
Solution:
Domain of relation is the set of x-values or the set of input values.
First line is defined from -4 to -2, second line is defined from -2 to 1 and third line is defined from 1 to 6.
There are closed circles at (-4, -4) and (6, 4). It means -4 and -6 are included in the domain.
Since the input values for the given relation is from -4 to 6, where -4 and 6 are included, therefore the domain of the relation is [-4,6].
