You have a 3-card deck containing a king, a queen, and a jack. You draw a random card, then put it back and draw a second random

card. Calculate the probability that you draw exactly 1 king.

Probability that you will draw exactly 1 king

P(draw both jacks) = 1/3*1/3 = 1/9P(no jacks) = 2/3*2/3 = 4/9P(1 jack) = 1 - 1/9 - 4/9 = 4/9

The axis of symmetry for the graph of the function f start bracket x end bracket equals one-quarter x square plus b x plus 10 is

zimovet [89]

The value of b is -3.

<h3>What is axis of symmetry?</h3>

Axis of symmetry is a line that divides an object into two halves,thereby creation a mirror like reflection of either side of the object.

Now the given function is,

f(x) = 1/4 x^2 bx + 10

and axis of symmetry is at x = 6

Now the quadratic function in standard form is given as,

f(x) = a x^2 bx + c

By comprison we get,

a = 1/4

c = 10

Since axis of symmetry is a vertical line

x = -b/2a

Therefore,

6 = -b/2*(1/4)

-b = 6*2*(1/4)

or, b = -12/4

or, b = -3

Hence,The value of b is -3.

Jeremy and Arnold are working on a project for math class in which they are to identify the quadratic equation that represents a

denis23 [38]

Answer:

The parabola generated by the expression :

$y=x^2-2x+3$

is the one that better represents a rain gauge above the ground.

Step-by-step explanation:

The function:

a) $y=x^2+11x+24$

Direction of parabola: branches pointing up

Location of vertex relative to x-axis: below

So, the parabola doesn't depict a rain gauge off the ground

b) $y=-x^2-6x-8$

Direction of parabola: branches pointing down

Location of vertex relative to x-axis: above

So, the parabola doesn't depict a rain gauge off the ground

c) $y=x^2-2x+3$

Direction of parabola: branches pointing up

Location of vertex relative to x-axis: two units above

So, the parabola depicts a rain gauge off the ground

d) $y=x^2+4x+4$

Direction of parabola: branches pointing up

Location of vertex relative to x-axis: right on the x-axis

So, the parabola doesn't depict a rain gauge off the ground (this is sitting on the ground)

e) $y=3x^2+21x+30$

Direction of parabola: branches pointing up

Location of vertex relative to x-axis: below

So, the parabola doesn't depict a rain gauge off the ground
