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.
15·0.8 + x = 30·0.9 --> x = 15
C. is the correct answer
X = -230/3 hope that helps
Answer:
can u show a little clear pic with full triangle shown
X is left and right
hmm
see the aproximate slope
see endpoints
ok, so from about (0,3) to (35,30)
slpoe is 27/35
so
y=(27/35)x+3 about
so when x=
ok, so according to the garph, when x=35, y=30, not 20
ok, so when x=40
y=(27/35)x+3
y=(27/35)*40+3
y=33.8571 about for x=40
