Answer:

1/8

Step-by-step explanation:

Given that A fair coin is flipped multiple times until it lands on heads.

The coin is unbiased.

We have to find the probability of first landing on heads on the third attempt.

We know that in a unbiased coin, each toss is independent of the other and also P(H) = P(T) = 0.5 in each attempt.

REquired probability = Probability of first landing on heads on the third attempt

= Prob of (I two trials result in tail and third result in head)

=P(I tail) P(II tail) P(III head) (since each trial is independent)

= (\frac{1}{2} )(\frac{1}{2} )(\frac{1}{2} )=\frac{1}{8}

Milo cut his cake into 2 equal pieces. He ate 2pieces of cake for his birthday.
Sauron [17]

Answer:

1  or \frac{2}{2}

Step-by-step explanation:

<h2><u>We know that Milo cut his cake into 2 different pieces, so:</u></h2>

\frac{x}{2}

<h2><u>He then eats two pieces of the cake. so:</u></h2>

2  pieces  of  cake  =  x

\frac{2}{2}   = 1

If y=8 when x =3, find y when x=45
Art [367]
Let's make things easier by simplifying things.

y = 8 and x = 3 is more likely to be understood as a ratio. So for the rest of the answer, their relationship would be represented as y:x

Thus: y:x = 8:3

The problem would be finding y when x = 45

Let us proceed on using the previous equation and substitute x with 45 which would look like this:

y:45 = 8:3

Ratios can also be expressed as fractions which would make things more understandable and easy to solve. So the new form of our equation would be like this:

y/45 = 8/3

Then we proceed with a cross multiplication where the equation becomes like as what is shown below:

3y = 45 * 8

From there, you can solve it by multiplying 45 and 8 then dividing the product with 3 to get y

3y = 360

y = 120

Another way of looking at the problem, especially problems like these, is to take the whole question or statement as an equation. it would probably look like this:

y = 8 when x = 3 : y = ? when x = 45

This would make you understand what approach you can use to solve the given problem.

What is the scale factor of dilation? (1 point)
dusya [7]

Answer:

On a coordinate plane, triangle A B C has points (4, 4), (7, 8), (10, 4). ... Hence, the scale factor is 2 and one-half( ).

Step-by-step explanation:

The center of dilation is a fixed point in the plane. If the scale factor is greater than 1, the image is an enlargement (a stretch). If the scale factor is between 0 and 1, the image is a reduction (a shrink). If the scale factor is 1, the figure and the image are congruent.
