The probability that a person wins the game is 32.1%

<h3>How to illustrate the probability?</h3>

Based on the information given, the following can be depicted. It should be noted that there are 6 sides as well as 4 cards.

Therefore, the numbers on the dice i.e from 1 - 6 will be represented 4 times each. This gives a total of (4 × 6) = 24. There are also 4 cards. The total in sample space will now be:

= 24 + 4 = 28

The frequency table will be such that 28 or more have a relative frequency of 9. Therefore, the probability that a person wins the game will be:

= 9/28 = 32.1%

When you win 25% of the time, this illustrates that the number of products picked will be:

= 25% × 28

= 7 products.

The probability of participants achieving a winning score of 36 or higher in four consecutive attempts will be:

= 1/6⁴ = 1/1296

Find an equation in slope intercept form of a line having slope 6 and y-intercept 2

xz_007 [3.2K]

Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

<em />

We have the slope <em>m = 6</em>, and the y-intercept <em>b = 2</em>.

Substitute:

$y=6x+2$

A parabola has a focus of F(8.5,−4) and a directrix of x=9.5.

HACTEHA [7]

Answer:

$-\frac{1}{2}y^2-4y+1=x$

Step-by-step explanation:

A parabola has a focus of F(8.5,−4) and a directrix of x=9.5.

General form of horizontal parabola is

$(y-k)^2=4p(x-h)$

the distance between directrix and focus is the value of p

so p = 8.5 - 9.5 = -0.5

Focus is (h+p , k), given focus is (8.5, -4)

So k = -4 and h+p = 8.5

we know p = -0.5

h +p = 8.5

h - 0.5 = 8.5

so h= 9 and k = -4

vertex is (h,k) that is (9, -4)

Now plug in the value in the general equation

$(y-k)^2=4p(x-h)$ , k= -4, h= 9 , p = -0.5

$(y+4)^2=4(-0.5)(x-9)$

$(y+4)^2=-2(x-9)$

$y^2+8y+16=-2x+18$

subtract 18 on both sides

$y^2+8y-2=-2x$

Divide whole equation by -2

$-\frac{1}{2}y^2-4y+1=x$
