Step-by-step explanation:
(a) If his second pass is the first that he completes, that means he doesn't complete his first pass.
P = P(not first) × P(second)
P = (1 − 0.694) (0.694)
P ≈ 0.212
(b) This time we're looking for the probability that he doesn't complete the first but does complete the second, or completes the first and not the second.
P = P(not first) × P(second) + P(first) × P(not second)
P = (1 − 0.694) (0.694) + (0.694) (1 − 0.694)
P ≈ 0.425
(c) Finally, we want the probability he doesn't complete either pass.
P = P(not first) × P(not second)
P = (1 − 0.694) (1 − 0.694)
P ≈ 0.094
Answer:
800 mm or 80 cm
Step-by-step explanation:
We are given that Jessica is measuring two line segments.
Length of first line segment =30 cm
Length of second line segment=300 mm
We have to find that Length of two line segments together
We know that 1 cm =10 mm
Length of firs line segment =
Length of two line segments together=500+300=800 mm=
Hence, the length of two line segments together=800 mm=80 cm

<em>-- let me know if you have any questions regarding this. </em>
Price of boots is represented as x, price of tennis shoes is represented as y.
x-y=44.38
x+y=196.12
Isolate x. (Or y, if you wanted to)
x=y+44.38
x=196.12-y
Set them equal to each other.
y+44.38=196.12-y
Solve for y. Then plug it in to either of the two original equations to find x.
x=120.24
y=75.86
Note: This is assuming that the boots are more expensive than the tennis shoes. If the tennis shoes are more expensive than the boots, then the prices would be switched. I didn't find this clear in your question.
40 % off means we pay 60 % (must total 100%)
original price * 60 % = 36.00
change percent to decimal
original price * .6 = 36
divide each side by .6
orginal price = 60
