Distribute the 2 to get the pink box

10x + 2y = 18
Then if we are subtracting the bottom equation from the pink box
10x + 2y = 18
-(10x -7y = -18)
9y = 36
y = 4

nikdorinn [45]

Answer:

∠C       ∠D

82°        98°

132°       48°

115°       65°

25°       155°

Step-by-step explanation:

180 -82 = 98

180 - 132 = 48

180 - 115 = 65

180 - 25 = 155

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
