We have three coins: one with heads on both faces, the second with tails on both faces, and the third a regular one. We choose o
Finger [1]

Answer:

Probability: \frac{1}{2} = 0.5 = 50%

Step-by-step explanation:

Based on the question one coin is chosen at random and tossed. That coin then lands and is heads. Since the coin landed on heads we can <u>eliminate the possibility</u> of the coin that was chosen being the coin with double tails.

The following possibilities are that the coin has double heads or is a regular coin with both tails and heads. Seeing as the coin landed on heads, there are only two possible out comes for the other side of the coin

The other side is either Heads or Tails. That gives us a 50% chance of the other side being tails.

\frac{1}{2} = 0.5 = 50%

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

What is the output of the function when the input is 0
bearhunter [10]

Answer:

y = -1

Step-by-step explanation:

Any ordinate pair (x, y) represents the input output values of a function to be graphed.

For any input value of x, there will be an output value (y).

If input value for the graph attached is x = 0,

Output value will be represented by the y-value along y-axis as, y = -1

Therefore, y = -1 will be the answer.

Are all whole numbers natural numbers?
RideAnS [48]

Answer:The whole numbers are the numbers 0, 1, 2, 3, 4, and so on (the natural numbers and zero). Negative numbers are not considered "whole numbers." All natural numbers are whole numbers, but not all whole numbers are natural numbers since zero is a whole number but not a natural number.

A line passing through the point (7, 6) has a slope of 2.
Masja [62]
An equation in point-slope form is
y - y1 = m (x - x1)

Your point is (7,6) and your slope is 2
y1 is the y coordinate of your point (in this case 6)
x1 is the x coordinate of your point (in this case 7)
m is your slope (in this case 2)

Now you just have to plug these numbers in:
y - 6 = 2 (x - 7)

Helpppppppppppppppppppp
Ganezh [65]

Answer:

See below ~

Step-by-step explanation:

<u>Q1</u>

  • y = (x + 3i)(x - 7)
  • y = x² + 3ix - 7x - 21
  • <u>y = x² + (3i - 7)x - 21</u>

<u>Q2</u>

  • y = (x - √5)(x - i)
  • y = x² - √5x - ix + √5i
  • <u>y = x² - (√5 + i)x + √5i</u>
