What is 4 1/3 times 4 1/2
Answer:
19 1/2
Step-by-step explanation:
4 1/3 = 13/3
4 1/2 = 9/2
13/3 x 9/2
13/1 x 3/2 ( 3 goes into nine so i simplified)
13 x 3/1 x 2 = 39/2 = 19 1/2

A nationwide poll asked a random sample of US adults the question, “Are you in favor of making Election Day a federal holiday?” Based on the results of this poll, the 95% confidence interval for the population proportion who favor making Election Day a federal holiday is (0.64, 0.70).
Calculate the point estimate and margin of error for the given confidence interval.
Enter both values to 2 decimal places.
The point estimate =
The margin of error =
Answer: point estimate = 0.67 and Margin of error = 0.03 .
Step-by-step explanation:
For confidence interval,
Lower limit = point estimate - margin of error
Upper limit = point estimate + margin of error
Given confidence interval: (0.64, 0.70)
i.e. Lower limit = 0.64
Upper limit = 0.70
i.e. point estimate - margin of error= 0.64 (i)
point estimate + margin of error= 0.70 (ii)
Adding (i) and (ii) , we get
2( point estimate) = 1.34
⇒ point estimate = 0.67
Eliminate (i) from (ii) , we get
2( Margin of error ) = 0.06
⇒ Margin of error = 0.03
Hence, point estimate = 0.67 and Margin of error = 0.03 .

Polynomial (3) [tex](-4x^2)+2xy^2+[10x^2y+(-4x^2y)][/tex] gives the sum of the given polynomial [tex]10x^2y+2xy^2-4x^2-4x^2y[/tex] with like terms grouped together.
What is Polynomial?Polynomial is a mathematical expression made of one or more algebraic terms (variable) with different powers and different combinations and coefficients.
We can add or subtract only like terms in a polynomial, and like terms are which have the same variable combination with similar power but the coefficient can be different.
Here given polynomial is [tex]=10x^2y+2xy^2-4x^2-4x^2y[/tex]
Here we have to group the like terms in the given polynomial which are [tex]10x^2y,(-4x^2y)[/tex].
So grouping the like terms we can write the sum of the given polynomial as [tex](-4x^2)+2xy^2+[10x^2y+(-4x^2y)][/tex].
Hence option (3) is correct.

Simplifying
4y + -10 = 5 + -1y
Reorder the terms:
-10 + 4y = 5 + -1y
Solving
-10 + 4y = 5 + -1y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add 'y' to each side of the equation.
-10 + 4y + y = 5 + -1y + y
Combine like terms: 4y + y = 5y
-10 + 5y = 5 + -1y + y
Combine like terms: -1y + y = 0
-10 + 5y = 5 + 0
-10 + 5y = 5
Add '10' to each side of the equation.
-10 + 10 + 5y = 5 + 10
Combine like terms: -10 + 10 = 0
0 + 5y = 5 + 10
5y = 5 + 10
Combine like terms: 5 + 10 = 15
5y = 15
Divide each side by '5'.
y = 3
Simplifying
y = 3

In a carnival drawing, a green ticket wins $1, a yellow ticket wins $5, and a blue ticket wins $10. There are 100 green tickets, 25 yellow tickets and 5 blue tickets. In simplest form, what are the odds in favor of winning $5 or more?
A. ) 1:4
B. ) 1:5
C. ) 1:25
D. ) 3:10
Answer:
D) 3:10
Step-by-step explanation:
Well only blues and yellows are at least $5. there are 25 yellows and 5 blues and if you add them together there's 30 in total. Now compare that 30 to 100 and you have 30:100. In the simplest form you have to divide both sides by 10 and it becomes 3:10.

This is due tomorrow and I am struggling. I don’t understand anything my math teacher teaches. I’m online cause I don’t like going to school and Im trying to make the best of it. I never thought this year I would have a math teacher like this. Last year my math teacher was such a good teacher. I passed every test in her class it was a piece of cake. But this year I’m not so lucky. So I’m asking if anyone can HELP ME PLEASE!!!! Oh and as a reminder there’s two math problems. U going to have to click it cause it’s an photo.
Step-by-step explanation:

(2 + √3)(2 - √3)
x² - y² = (x + y)(x - y)x = 2, y= √3x² = 2² = 4y² = √3² = 3(2 + √3)(2 - √3) = 4 - 3 = 13.
(6 + √5)/(6 - √5)
Multiply both numerator and denominator by (6 + √5) to simplify(6 - √5) ((6 + √5) = 6² - √5² = 36 - 5 = 31(6 + √5)/(6 +√5) = 6² + 2*6*√5 + √5² = 36 + 12√5 + 5 = 41 + 12√5(6 + √5)/(6 - √5) = (41 + 12√5)/31How can you use x- and y- intercepts to graph an equation
Answer:
Since two points determine any line, we can graph lines using the x- and y-intercepts. To find the x-intercept, set y = 0 and solve for x. To find the y-intercept, set x = 0 and solve for y. This method of finding x- and y-intercepts will be used throughout our study of algebra because it works for any equation.
