Consider the experiment of flipping a coin 4 times where the probability of flipping a heads is 0.18. So each outcome of the exp
seropon [69]

Answer:

0.397

Step-by-step explanation:

In the experiment, if the coin is flipped 4 times, the outcomes in which there is a single heads out of the 4 flips are:

HTTT,THTT,TTHT and TTTH

The probability of flipping a head, P(Head)=0.18

Therefore: The probability of flipping a tail, P(Tail)=1-0.18=0.82

We can then calculate the probability that there is a single heads out of the 4 flips

=P(HTTT)+P(THTT)+P(TTHT)+P(TTTH)

=(0.18 X 0.82 X 0.82 X 0.82) + (0.82 X 0.18 X  0.82 X 0.82) + (0.82  X  0.82 X 0.18 X 0.82 )+ (0.82  X  0.82 X 0.82 X 0.18)

=4(0.18X0.82^3)\\=0.39698496\\\approx 0.397

Help ME????????????????????
natka813 [3]

Answer:

3 x -10.5

Step-by-step explanation:

The problem says "each for -10.50." That means every entry has a change of -10.5.

We know there are 3 entries so we are going to multiply 3 x -10.5 (The expression is the answer, not the actual answer.)

Step 1. Since 8 x 8 = 64, The square root of 64 is 8.
v^{2} =-8

Step 2. Take the square root of both sides.

v= + \sqrt{-8}
<span>
Step 3. </span>Simplify \sqrt{-8} to ( \sqrt{8j})

v = +  \sqrt{8j}


Step 4. Simplify square root

v=+2 \sqrt{2j}
