4.5/y = 12.5/4 PLEASE HELP!!! SOS
garik1379 [7]

Answer:

y = 1.44

Step-by-step explanation:

What are you aiming to do here?  Please share all instructions with each problem.

If you want to solve 4.5/y = 12.5/4 for y:  Multiply both sides by 4y:

18 = 12.5y.  Then y = 1.44

What is the conditional probability that exactly four heads appear when a fair coin is flipped five times given that the first f
Phantasy [73]

Presumably, the coin tosses are independent of one another, so

P(\text{exactly 4 heads}\mid\text{first flip is tails})=P(\text{exactly 4 heads})=\dfrac1{2^4}=\dfrac1{16}

But if the coin flips are not independent, then we can't really say anything about this probability without any more information about how the flips are related...

<h3>What is a Triangle ?</h3>

A triangle is a polygon with three sides , three angles and three vertices.

According to the Proportionality Theorem

When a line is parallel to one side and intersects the other lines at two different points then it divides both the line in similar ratio.

As in the given figure DC is parallel to AP ,

then RD : DP = RC:CA

42:15 = x: 10

42/15 = x / 10

x = 42 * 10 /15

x = 28

Therefore the value of x is 28 .

Find the midpoint of the line segment joining the points R(3,2) and S(-5,5).
inessss [21]

The x coordinates are 3 and -5. They add to 3+(-5) = -2

Cut this in half to get -2/2 = -1

The x coordinate of the midpoint is x = -1

-------------------

The y coordinates are 2 and 5. They add to 2+5 = 7.

Then we cut this in half to get 7/2 = 3.5

The y coordinate of the midpoint is y = 3.5

-------------------

Overall, the midpoint is (-1, 3.5)

<h3>Answer: (-1, 3.5) which is the same as (-1, 7/2)</h3>
