If a recent survey shows that of the 600 parrot owners surveyed, 200 successfully trained their birds to say words, then out of a population of 1,500, people have trained their birds

Answers

Answer 1

Answer: Hello!

You first have to find the percentage of the tested group that trained their birds

200 / 600 = 0.333...

Multiply this by the amount of people

200/ 600 * 1500 = 500

The answer is 500 people

Hope this helps!

What are the coordinates of the vertices of the image after a 90-degree counter-clockwise rotation about the origin?
(2,3)
(-3,-1)
(2, -1)

Answers

The coordinates of the vertices of the image after the 90-degree counter- clockwise rotation about the origin is :

( - 3, 2 )
( 1, -3 )
( 1, 2 )

How to rotate 90-degree counter- clockwise rotation about the origin?

To perform a 90-degree counterclockwise rotation about the origin, follow these steps:

Write down the coordinates of the point you want to rotate. Let's call the point ( x , y).
To perform a counterclockwise rotation, switch the x and y-coordinates and negate the new x-coordinate. The new coordinates will be ( - y , x).

This means that the vertices will become :

( 2 , 3) ⇒ ( - 3, 2 )

( - 3, -1) ⇒ ( 1, -3 )

( 2, - 1) ⇒ ( 1, 2 )

At a basketball game, a vender sold a combined total of 108 sodas and hot dogs. The number of sodas sold was three times the number of hot dogs sold. Find the number of sodas and the number of hot dogs sold.

Answers

Answer:

Hot dogs - 27, soda - 81

Step-by-step explanation:

Soda to Hot dog ratio = 3:1

If the total is 108, we can divide 108/4 ---> 27

now, multiply 3 and 1 by 27 and there you go!

edit: also if you don't know why I divided 108 by 4, its because you add together both sides of the ratio

Write an equation in point slope form of the line that passes through the given point and the given slope m(-9,8) and m=4

Answers

Answer:

The answer is

$\huge y - 8 = 4(x + 9) \n$

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

$y - y_1 = m(x - x_1)$

From the question we have the final answer as

$y - 8 = 4(x + 9)$

A formal power series over R is a formal infinite sum f = X[infinity] n=0 anxn, where the coefficients an ∈ R. We add power series term-by-term, and two power series are the same if all their coefficients are the same. (We don’t plug numbers in for x, because we don’t want to worry about issues with convergence of the sum.) There is a vector space V whose elements are the formal power series over R. There is a derivative operator D ∈ L(V ) defined by taking the derivative term-by-term: D X[infinity] n=0 anxn ! = X[infinity] n=0 (n + 1)an+1xn What are the eigenvalues of D? For each eigenvalue λ, give a basis of the eigenspace E(D, λ). (Hint: construct eigenvectors by solving the equation Df = λf term-by-term.)
