Step-by-step explanation:
(b) On the average, how many motherboards should be inspected until a motherboard that passes inspection is found?
a. The probability that at least 13 of the next 15 motherboards pass inspection is 0.604.
b. On average, 1.1765 motherboards should be inspected until a motherboard that passes inspection is found.
a.
The formula for the probability of getting exactly k successes in n trials with a success probability of p is:
Where "n choose k" represents the binomial coefficient, which is calculated as n! / (k! * (n - k)!), where "!" denotes factorial.
In this case:
n = 15 (number of trials)
k = 13, 14, 15 (number of successes)
p = 0.85 (probability of success)
First, let's calculate the probability that exactly 13, 14, and 15 motherboards pass inspection.
For k = 13:
= 0.28564
For k = 14:
= 0.23123
For k = 15:
= 0.08735
Now, sum these probabilities to get the final answer:
P(at least 13) = P(X = 13) + P(X = 14) + P(X = 15)
= 0.28564 + 0.23123 + 0.08735
= 0.60422
= 0.604
(b)
The average number of trials needed until a motherboard that passes inspection is found can be calculated using the concept of the expected value of a geometric distribution:
Expected value (E) = 1 / p
Where p is the probability of success.
In this case, p = 0.85.
E = 1 / 0.85
= 1.1765
Thus, on average, 1.1765 motherboards should be inspected until a motherboard that passes inspection is found.

To find the probability that at least 13 of the next 15 motherboards pass the inspection, use the binomial formula for each scenario (13, 14, and 15 passing) and sum the results. To find on average how many motherboards need to be inspected for one to pass inspection, just take the reciprocal of the probability of success (1/0.85).
This question falls under the domain of probability and statistics. Let's tackle each part separately:
(a) When we talk about at least 13 out of 15 motherboards passing, we have to consider the situations where exactly 13, 14, or all 15 pass. For each case, you would use the binomial formula P(X=k) = C(n, k) * (p^k) * ((1-p)^(n-k)). In this formula, n is the number of trials (which is 15), k is the number of successes we are interested in, p is the probability of a success (which is 0.85), C(n, k) is a combination that represents the different ways k successes can happen in n trials. Calculate this for k = 13, 14, and 15 and sum the results to get the probability for at least 13 to pass.
(b) To find on average how many motherboards should be inspected until one passes is straightforward - it is simply the reciprocal of the probability of success which is 1/0.85.

Answer:
460 m
Step-by-step explanation:
Use right triangle PSR with right angle S to find the length of PS.
The Pythagorean theorem can be used for this.
a^2 + b^2 = c^2
(PS)^2 + (SR)^2 = (PR)^2
(PS)^2 + (150 m)^2 = (170 m)^2
(PS)^2 = 22500 m^2 = 28900 m^2
(PS)^2 = 6400 m^2
PS = 80 m
PS = 80 m; SR = 150 m
perimeter = 2(length + width)
perimeter = 2(150 m + 80 m)
perimeter = 2(230 m)
perimeter = 460 m

a. Complete the congruence statement: △MNK ≅ △_______
b. What side is congruent to ≅ ______
c. Solve for x. _____
The given statements to be completed are completed as follows;
A) △MNK ≅ △RTP
B) TR ≅ NM
C) x = 7
We are given that;
△NMK ≅ △TRP
This means that Triangle NMK is congruent to Triangle TRP.
A) The naming of △NMK is now △MNK. Thus, we have to now re-name Triangle TRP to match the naming of △MNK. Thus;
△MNK ≅ △RTP
B) From the 2 given triangles, we can see that TR and NM are the same length and also perpendicular lines.
Thus they are congruent to each other and as such;
TR ≅ NM
C) Since TR and NM are congruent to each other. Then;
TR = NM
Thus;
3x - 1 = 20
3x = 20 + 1
3x = 21
x = 21/3
x = 7
