Answer:

Point A.

Step-by-step explanation:

A complex number is composed of 2 parts: it's Real Part often denoted with Re(z), where z - complex number, Im(z) - imaginary part of z.

The number can be thought of as a point on the xy axis where Re(z) serves as the x coordinate and Im(z) serves as the y component, thus giving you the position. (Re(z), Im(z))

Find the center, vertices, and foci of the ellipse with equation x squared divided by 400 plus y squared divided by 625 = 1
Inessa05 [86]

Answer:

x^2/400 + x^2/625

(x-0)^2/400) +(y-0^2/625)

x^2=400

X=sqrt. 400

x = 20

y^2=625

y = sqrt. 625

y= 25

a^2-c^2=b^2

sqrt 400-625 = c

20-25=c

The correct answer is c=-5

For the spinner above, the probability of landing on black is 1/2, and the probability of landing on red is 1/3. Suppose it is s
saul85 [17]

Answer:

d) The probability spinner will land on black all three times is 1/8

Step-by-step explanation:

The probability of landing on black = 1/2

The probability of landing on red    =  1/3.

Now, if the spinner is spun 3 times.

The probability  it will land on black all three times  

= \textrm{ (The probability of landing on black)}^3

= \frac{1}{2}   \times  \frac{1}{2}  \times  \frac{1}{2}  = \frac{1}{2 \times 2 \times 2 } = \frac{1}{8}

Hence, the probability spinner will land on black all three times is 1/8.
