Answer:

A. 1/32

Step-by-step explanation:

Ok, the probability for one of the coins to land on heads is 1/2 cause a coin have to sides and chance is 50% that it will land on either of its sides.

If you have 2 coins the probability will be 1/2 for the first coin to land on heads and 1/2 for the second one. The overall probability for 2 coins would be (1/2)*(1/2)=1/4. You could also see it is 1/4 because all of the possible combinations of 2 coins are 4 (HH, HT, TH, TT) and HH is one of four.

It's the same if you have 5 coins. The probability will be (1/2)*(1/2)*(1/2)*(1/2)*(1/2)=1/32 in other words HHHHH is one of 32 possible combinations of 5 coins.

Complete the proof to show that ABCD is a parallelogram.
LuckyWell [14K]

In the proof given, BC║AD and CD║BA because: B. slopes of opposite sides are equal.

<h3>What is the Slope of Parallel Lines?</h3>

If two lines are parallel, they will have the same slope value,.

Slope = rise/run.

Slope of BC = rise/run = -2/5

Slope of AD = -2/5

Slope of BA = rise/run = -6/1 = -6

Slope of BA = rise/run = -6/1 = -6

Therefore, we can conclude that BC║AD and CD║BA because: B. slopes of opposite sides are equal.

2(3x–1)=9(x–2)–7 simplify plz help
iVinArrow [24]

Hi

2(3x-1) = 9(x-2)-7

6x-2 = 9x-18-7

6x-9x = 2-18-7

  -3x = -23

      x =  23/3

The formula for the perimeter of a rectangle can be expressed in more than one way. One way is P=2(l + w). Discuss how you could
ruslelena [56]
First you would divide by 2 in both sides
P/2 = l + w

Then you would subtract w from both sides
P/2 - w = l

This is the easiest method do isolate l

You can also distribute the 2 to ( l + w) first
P= 2l + 2w

Then subtract 2w from both sides
P - 2w = 2l

Then you would divide by 2
(P - 2w) / 2 = l
P/2 - w = l
