The probability of heads for one flip of a fair coin is
P(heads) = 1/2 =0.50

Allisa [31]3 years ago
4 0

Answer: 0.50

Step-by-step explanation:

The given statement :- You flip a fair coin

The outcomes of flipping a fair coin : Tail or Heads

i.e. the total number of possible outcomes =2

The number of favorable outcome (Head)=1

Now, if you flip a fair coin the probability of getting head is given by :-

\text{P(Head)}=\dfrac{\text{Favorable outcome}}{\text{Total outcomes}}\\\\=\dfrac{1}{2}=0.50

Hence, \text{P(Head)}=0.50

On a number line, suppose point E has a coordinate of 4, and EG = 11. What are the possible coordinates of point G?
navik [9.2K]

Answer:

  -7, 15

Step-by-step explanation:

The positive difference between E and G is 11.

<h3>Solution</h3>

  G - E = 11

  G = 11 + E = 11 + 4

  G = 15 . . . . . . . . . . . . . when G is right of E

__

  E - G = 11

  E - 11 = G = 4 - 11

  G = -7 . . . . . . . . . . . . when G is left of E

Possible coordinates for G are -7 and 15.

I NEED HELP ON THIS CONSTRUCTED RESPONSE! :(
Simora [160]

Answer:

<em>x = -10</em>

Step-by-step explanation:

(9/2)(8 - x) + 36 = 102 - (5/2)(3x + 24)

Multiply both sides by 2.

9(8 - x) + 2 * 36 = 2 * 102 - 5(3x + 24)

Distribute on both sides.

72 - 9x + 72 = 204 - 15x - 120

Combine like terms on each side.

144 - 9x = 84 - 15x

Subtract 144 from both sides. Add 15x to both sides.

6x = -60

Divide both sides by 6.

x = -10

Cindy has 26 nickels. She is getting rolls of nickels from the bank. She has enough money to get up to 10 rolls of nickels and e
Alchen [17]

We know that the domain is actually the number of rolls that she gets because it is the input variable in the equation  f (r) = 40 r + 26. The number of rolls that she can get can never be a negative number nor a zero nor a decimal number. However she can only get up to 10 rolls. Therefore the answer is:

 

all integers from 1 to 10, inclusive
