Tossing the coin it will either be heads or tails, so the chances of getting tails is 1/2, sample space is just 2 possible outcomes.
now, what is the probability of getting Tails AND Tails AND Tails AND Tails AND Tails AND Tails?
well, keep in mind that AND means "times" or the product, so, since the probability of getting tails once is 1/2, the probability of getting tails 6 times in a row is
we have two similar triangles.
we know that in similar traingles ratios of the corresponding sides are always equal.
we have AB is propotional to PQ
BC is propotional to QR
AC is propotionbal to PR
here we dont have the lengths of sides
so the length of PR and QR will be equal to some constant have same value .
Correct question:
Jada walks up to a tank that can hold up to 10 gallons. When it is active, a drain empties water from the tank at a constant rate. When Jada first sees the tank, it contains 7 gallons of water. Three minutes later, the tank contains 5 gallons of water. At what rate is the amount of water in the tank changing? use a signed number, and include the unit of measurement in your answer.
Answer: - 2/3
Step-by-step explanation:
Given the following :
Amount of gallon tank can hold = 10
tank drains at a constant rate :
First look tank contains 7 gallons
After 3 minute,
Tank contains 5 gallons
Thus signifies a 2 gallon decrease in volume of water after 3 minutes
Therefore, the rate of change =( change in volume) / time
Rate of change = (final volume - initial volume ) / 3
(5 - 7)/ 3 = - 2/3
Answer:
60°
Step-by-step explanation:
Assuming the dot is the center of the circle, all sides of the triangle appear to be equal (i.e., 7). This means all its angles must be 60° (180° divided equally), so the angle is 60°.
