Answer: 1.57
Step-by-step explanation:
When solving for the arc you have to find the circumference.
For circumference you'll need the diameter which is 2x the radius.
So, your equation would be
1/4{(pi)(2)} = x
or
1/4{(3.14)(2)} = x
To Solve:
3.14 times 2 equals 6.28
Divide by 4 or multiply by 1/4 to get 1.57
Not sure if this is correct, I haven't learned the topic myself, but this week's to be there most reasonable way to look at it. For me anyway.
Answer:
IIf it takes 8 seconds to move 2 feet, then it takes 4 seconds to move 1 foot
She is already 20 feet below sea level meaning she only needs 30 more feet to reach 50 ft below sea level.
tto figure out the amount of time it will take her to descend 30ft you multiply 30(distance) x 4(time)
tthe answer is 120
Step-by-step explanation:
Probability that a stone is cracked = 15/600; denote this event by .
Probability that a stone is discolored = 27/600; denote this event by .
Probability that a stone is neither cracked nor discolored = 562/600; in terms of and , this event is captured by .
a. We want to find . Use the known probability of its complement:
b. We want to find . By the inclusion-exclusion principle,
c. By the law of total probability,
You should send a clearer picture. I have problems reading this.
