And for this case we can use the cumulative distribution given by:

And for this case if we use this formula and the complement rule we have:

Step-by-step explanation:
Let X the random variable who represent the pizza delivery time and we know that the distribution for x is given by:

And we want to find the following probability:

And for this case we can use the cumulative distribution given by:

And for this case if we use this formula and the complement rule we have:

Answer:
Answer is -7 Hope this helps :D
Step-by-step explanation:
Answer:
B.
Step-by-step explanation:
Since 6 = 5r + 1, r = 1
As for s, if s is 2, then you can do
4 x 2 + 5 = 13 & 6 x 2 + 1 = 13
13 = 13
So B!
Hope that helps!
Answer:
Step-by-step explanation:
so when the height is zero, that's when the rocket hits the ground. The equation will have two zeros, but one would be for a negative time, or before the rocket is launched. so we only one the one after the rocket is launched.
use the quadratic formula to solve for x ( which is time)
-124 +- sqrt [
- 4*(-16)*(127) ] / 2 (-16)
-124 +- sqrt [15376 + 8128 ] / -32
-124 +- sqrt [23504 ] / -32
-124 +- 153.310 / -32
if we take the positive part it will become the negative time so skip that one try the negative part 1st
-124 - 153.310 / -32
-277.310 / -32
8.6659 seconds to hit the ground. ( time of flight) aka TOF
8.67 seconds ( rounded to nearest 100th)
5x+1(6-4) = +1(5x6)-(5x)
this would be a hard question to answer but i think i can do it ((( nNOTTTT))))
