URGENTTTTTTTT!! HELP QUICK PLZZZZZZZZz

<h3>Answer:  72%</h3>

Explanation:

The phrasing "given that he or she is a graduate" means we focus on the middle row only. We ignore everything else.

We see that A = 1879 graduates receive financial aid out of B = 2610 graduates total.

This means the probability we want is therefore A/B = 1879/2610 = 0.7199 approximately. This converts to 71.99% and that rounds to 72%

Describe how the graph of y=-x^2+1 differs from y=x^2. Then find the axis of symmetry and the vertex.
nasty-shy [4]
Both the equation show a graph of a parabola. The equation y=-x^2+1 is a parabola opening downward since the x variable has a negative sign. While the equation y=x^2 is also a parabola opening upward since x^2 is positive. Both parabola have axis of symmetry on the y-axis. Vertex for the first parabola is on (0,1) while the second parabola is at the origin.

d1i1m1o1n [39]

Answer:

300 words in Hungarian and 570 in Polish.

Step-by-step explanation:

I guess you need to know the number of words in Hungarian and in Polish.

Let H be the words he said in Hungarian, and P the words he said in Polish.

We are told that Sakura uttered a total of 270 more words in Polish than in Hungarian, therefore:

P = H + 270

And that I speak for 5 minutes, we know that the speed of words in Hungarian is 150 and in Polish it is 190, therefore:

5 = H / 150 + P / 190

Thus we have two equations and two unknowns, that is, it has a solution, replacing P:

5 = H / 150 + (H +270) / 190

5 = (190 * H + 150 * H + 270 * 150) / (150 * 190)

5 * 150 * 190 = 340 * H + 270 * 150

H = (5 * 150 * 190 - 270 * 150) / 340

H = 300

Therefore he said 300 words in Hungarian.

In Polish it would be:

P = 300 + 270 = 570

To check we have to:

300/150 + 570/190 = 5

Therefore, Sakura giving the instructions said 300 words in Hungarian and 570 in Polish.

What type of number is √5? Choose all answers that apply:
Vlada [557]
<h2>SOLVING</h2>

\Large\maltese\underline{\textsf{A. What is Asked}}

What type of number is \bf{\sqrt 5}? Select all that apply

\Large\maltese\underline{\textsf{B. This problem has been solved!}}

Let's start by taking a look at all the four sets of numbers.

<h2>A: Whole number</h2><h3>{0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22...∞}</h3>

The set is shown above. To be honest, this is an infinitely small part of the number set; the whole number set would take FOREVER to type ;)

<h2>B: Integers</h2><h3>{∞...-2,-1,0,1,2,3,4,5,6,7,8,9...∞}</h3>

Wow, this set starts at negative infinity and ends at positive infinity!

<h2>C: Rational</h2>

This set consists of all integers, decimals, and fractions.

<h2>D: Irrational</h2>

That's where the desired number \bf{\sqrt{5}} belongs!

\cline{1-2}

\bf{Result:}

                 \bf{=The\;fourth\;option}

\LARGE\boxed{\bf{aesthetics \not1\theta l}}
