Answer:
0.095163
Step-by-step explanation:
given that a starter motor used in a space vehicle has a high rate of reliability and was reputed to start on any given occasion with probability .99999
Here we find that for any start, there are exactly two outcomes either success or failure.
Also each start is independent of the other since p = 0.99999 for succss is given constant.
Thus X no of successes is binomial with p = 0.99999 and n =10000
If Y is taken as failure then Y is binomial with p' = 0.00001 and n =10000
Required probability
= the probability of at least one failure in the next 10,000 starts
= 1-P(no failure in 10000 starts)
=
Answer:
Lets mark the unmarked angle as angle A and the base of the building as BC
We can use tan to find this
tan=opposite/adjacent
by knowing the 2 interior angles we can calculate the measure of A sicne the interior angles of any triangle add up to 180
52+90+A=180
142+a=180
38=a
tan(38)=BC/300
300 tan(38)=bc
using a calculator we see that bc=234.385689 or 234meters rounded
Step-by-step explanation:
Answer: -16 ≤ y
Step-by-step explanation: All we need to do is subtract 8 on both sides.
Hope this helped! :)
Answer:
Given - Triangle ABC
AD bisects BC ( I.e AB = AD)
To prove - Angle BAD = Angle CAD
Solution -
AB = AD (given)
Angle B = Angle C ( angle opposite to equal sides are also equal )
In a triangle BAD and CAD
AD = AD ( common)
angle B = Angle C ( prove above)
AB = AD = ( given )
By SAS congruence Triangle ABC is congruent to Triangle ABD
by CPCT BAD = CAD
hence, Proved
