Derek has a white cube and a red cube.
cluponka [151]

Answer:

1/72

Step-by-step explanation:

Probability of getting a 4 on white cube is:

P(W) · P(4) = 1/2 × 1/6 = 1/12

P(R) · P(>4) = 1/2 × 2/6 = 1/6

multiply both probabilities:  1/12 × 1/6 = 1/72

GEOMETRY URGENT HELP NEEDED
son4ous [18]

First we find the measurement of dark dot .

ANd for that we have to use the formula of the angle formed by the intersection of chord .

Let the dark dot be t.

So we have

t =\frac{1}{2} (96+66)=81

t and z are linear pair and sum of angles of linear pair =180 degree.

So we get

t+z=180 \\ 81+z =180 \\ z = 180-81 =99 degree

F(x) = x2 – 2x - 8
maw [93]

Answer:

The y-intercept is the point (0,-8)

see the attached figure

Step-by-step explanation:

we have

f(x)=x^{2}-2x-8

we know that

The y-intercept is the value of the function f(x) when the value of x is equal to zero

so

For x=0

f(x)=0^{2}-2(0)-8\\f(x)=-8

therefore

The y-intercept is the point (0,-8)

see the attached figure to better understand the problem
