Answer:
distributive property
Step-by-step explanation:
Distributive property says that x(y + z) = (x*y) + (x *z)
Answer:
a) 
b) 
Step-by-step explanation:

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:
And 0 for other case. Let X the random variable that represent "life lengths of automobile tires of a certain brand" and we know that the distribution is given by:
The cumulative distribution function is given by:
Part a
We want to find this probability:
and for this case we can use the cumulative distribution function to find it like this:
Part b
For this case w want to find this probability
We have an important property on the exponential distribution called "Memoryless" property and says this:
On this case if we use this property we have this:
We can use the definition of the density function and find this probability:
Well its a pretty strong wind the answer is 75 mph
First you find out the distance without the wind which is 4x525 or 2,100
Now subtract 1800 from that and you get 300
But you’re still not done because 300 is the number of miles effected by the wind in the whole flight of 4 hours.
So just divide it by 4 and you get 75. So the wind is a 75 mph wind.

Answer:
Step-by-step explanation:
1 - 2 + 10 o lw. First find a common denominator. 3 * 5. After cross reducing, multiply across ... Divide the fraction to get a decimal answer. 21 into a an. Jinit. 5 = 1.25 ... 3 = -x +8. -8 = -8. = -5 = -X. =-1(-5) = -x (-1). = 5 = x. Set up a ratio, and cross ... Combine like terms, and solve for x. Divide both sides by 2. = x= 20. = 5-1">4.
Hi
1. Temp was 5 at noon and dropped 59 degrees at midnight. 5+(-59)= -54 (B)
2. The stock dropped by 5 points and opened at 93 points that day.
93+(-5)=88 points (B)
3. The temperature fell by 12° over 4 hours.
12÷4=3° decreased per hour (C)
Hope that clarifies these. Let me know if these aren't clear.
