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.
The answer is b. The equivalent of -7/8 is 7/-8.
Start by just writing the equation for the line in slope intercept formula.
points: (-4,0) ; (4,2)
slope = (2-0)/(4+4) = 1/4
y-intercept, b = 1
(looked at graph)
equation line:
y = (1/4)x + 1
solid line is "equal to"
shaded area is below means y-values are "less than" the expression.
y <= (1/4)x + 1
