Answer by JKismyhusbandbae: 56 + 8x
Explanation: The distributive property says that the product of a number and a sum is equal to the sum of the individual products of the addends and the number. Using this information, multiply the value outside of the parentheses by each of the factors in the parentheses to write the equivalent equation.
Answer: The distance from ship B to the submarine is 1270.68 feet and the distance from ship A to the submarine is 1084.18 feet.
Step-by-step explanation:
Since we have given that
Distance between Ships A and B = 1425 feet
Angle of depression from ship A to the submarine =59°
Angle of depression from ship B to the submarine = 47°
As shown in the figure below:
Remaining angle will be
So, we will use "Sine formula ":
Similarly,
Hence, the distance from ship B to the submarine is 1270.68 feet and the distance from ship A to the submarine is 1084.18 feet.
Answer:
227
Step-by-step explanation:
first, multiply 19$ by 8 (for total months)
the answer is 152
now add 75 to 152 to get final cost after initial enrollment fee.
35,500-27,500= 8000 meaning $8,000 is the profit and the percentage is %35
Answer:
Step-by-step explanation:
Previous concepts
The exponential distribution is "the probability distribution of the time between events in a Poisson process (a process in which events occur continuously and independently at a constant average rate). It is a particular case of the gamma distribution". The probability density function is given by:
Solution to the problem
For this case the time between breakdowns representing our random variable T is exponentially distirbuted
So on this case we can find the value of like this:
So then our density function would be given by:
The exponential distribution is useful when we want to describe the waiting time between Poisson occurrences. If we assume that the random variable T represent the waiting time between two consecutive event, we can define the probability that 0 events occurs between the start and a time t, like this:
And on this case we are looking for this probability:
