Answer:
C
Step-by-step explanation:
Dividing zero by any value gives a result of zero, thus
= 0 → C
Answer:
28.65% probability that the next customer will not arrive for 5 minutes
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
Mean of 15 customers an hour:
An hour has 60 minutes, so in the space of 5 minutes, the mean is:
A customer walks in what is the probability that the next customer will not arrive for 5 minutes?
This is P(X = 0).
28.65% probability that the next customer will not arrive for 5 minutes
Answer:
Jess bought 403 pounds of each type of candy
Step-by-step explanation:
For this reason, though the PEA Mathematics Department promotes ... for me. It went over basic algebra and problem-solving techniques. ... priced at $4 per pound and candy priced at $3.50 per pound. Given that the bill came to. $20.75, figure out how many pounds of each type of candy Jess bought. 403.
Sorry if this is wrong and hope I helped! ^^
One <em><u>possible answer </u></em>is:
Draw segments from P to R and from P to Q; the triangles formed will be congruent by the SAS congruence theorem.
Explanation:
Drawing segments from P to R and from P to Q creates triangles PSR and PSQ.
In these two triangles, we know that RS ≅ SQ and PS≅PS.
Since PS is the perpendicular bisector of RQ, we also know that ∠PSR = 90; this is the same as ∠PSQ, so the two angles are congruent.
This means we have two sides and the angle between them congruent; this is the SAS postulate, which proves the triangles are congruent.
Since the triangles are congruent, all corresponding sides are congruent; this means that PR ≅ PQ.
