Answer:
5% chance
Step-by-step explanation:
devide how many students the teacher will choose from the amount of students there is to choose from:
1 / 20 = 0.05
then multiply by 100 to get the amount expressed in percentage:
.05 * 100 = 5%
the result:

Answer:
[tex]7\sqrt{3} +12\sqrt{2}[/tex]
Step-by-step explanation:
[tex]\sqrt{12} -\sqrt{18} +3\sqrt{50} +\sqrt{75}[/tex]
[tex]\implies \sqrt{4\times3} -\sqrt{9\times2} +3\sqrt{25\times2} +\sqrt{25\times3}[/tex]
[tex]\implies \sqrt{4}\sqrt{3} -\sqrt{9}\sqrt{2} +3\sqrt{25}\sqrt{2} +\sqrt{25}\sqrt{3}[/tex]
[tex]\implies 2\sqrt{3} -3\sqrt{2} +3(5)\sqrt{2} +5\sqrt{3}[/tex]
[tex]\implies 2\sqrt{3} -3\sqrt{2} +15\sqrt{2} +5\sqrt{3}[/tex]
[tex]\implies 2\sqrt{3} +5\sqrt{3} +15\sqrt{2} -3\sqrt{2}[/tex]
[tex]\implies 7\sqrt{3} +12\sqrt{2}[/tex]
Which of the equations below could be the equation of this parabola?
A. y = 4x2
B. x = 4y2
C. X=-4x2
D. Y=-4x2
Answer:
D
Step-by-step explanation:
The graph opens downward so we would expect the integer to be negative. Also because the parabola opens downward you cannot have the equation be X=, this leaves Y=-4xsquared as the only viable option
Evaluate. Express your answer to the nearest tenth, if necessary.

The graph of f of x equals x squared is shown. A transformation is applied to f of x resulting in the function g of x equals x squared plus 2. Which graph shows g of x?Answer options with 4 options.F of x is a parabola with a vertex at (0, 0) that opens up. G of x is a parabola with a vertex at (2, 0) that opens up.C.F of x is a parabola with a vertex at (0, 0) that opens up. G of x is a parabola with a vertex at (0, negative 2) that opens up.B.F of x is a parabola with a vertex at (0, 0) that opens up. G of x is a parabola with a vertex at (0, 2) that opens up.D.F of x is a parabola with a vertex at (0, 0) that opens up. G of x is a parabola with a vertex at (negative 2, 0) that opens up.
Answer:
f(x) is a parabola with a vertex at (0, 0) that opens up
g(x) is a parabola with a vertex at (0, 2) that opens up
Step-by-step explanation:
Quadratic equation: [tex]y = ax^2 + bx + c[/tex]
The graph of a quadratic equation is a parabola. The value of [tex]a[/tex]determines its orientation.
If [tex]a>0[/tex] then the parabola opens upwards and its vertex is its minimum point.
If [tex]a<0[/tex] then the parabola opens downwards and its vertex is its maximum point.
Given:
f(x) = x²g(x) = x² + 2⇒ g(x) = f(x) + 2
So the transformation of f(x) to g(x) is an upward shift of 2 units, or
a translation of f(x) by the vector [tex]\left(\begin{array}{ccc}0\\2\end{array}\right)[/tex].
Therefore, the y-coordinate of the vertex of g(x) will be 2 units more than the y-coordinate of the vertex of f(x).
Therefore,
f(x) is a parabola that opens upwards with a vertex at (0, 0)g(x) s a parabola that opens upwards with a vertex at (0, 2)Carolyn swim 35 laps in 1/2 hour. How far will she swim in 4 hours? Please help.

A scuba diver is 30 feet below the surface of the water 10 seconds after he entered the water and 120 feet below the surface after 40 seconds. What is the scuba diver's rate of change (include the units)?
Find slope(Rate of Change)
Answer:
3 feet per secondStep-by-step explanation:
The rate of change is:
m = the change in depth / the change in time = (120 - 30) / (40 - 10) = 90 / 30 = 3 feet/secondTake 2 points
(10,30)(40,120)Rate of change=Slope:-
[tex]\\ \rm\hookrightarrow m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\\ \rm\hookrightarrow m=\dfrac{120-30}{40-10}[/tex]
[tex]\\ \rm\hookrightarrow m=\dfrac{90}{30}[/tex]
[tex]\\ \rm\hookrightarrow m=3ft/s[/tex]
