Answer:
u = v - at
Step-by-step explanation:
v = u + at
v - at = u + at - at
v - at = u
u = v - at
Answer:
0.070
Step-by-step explanation:
Y = number on trial
Y has a negative binomial distribution
r = 3
P = 30% = 0.3 probability of positive indication.
P(Y = 11) probability of 11 employees that must be tested to get 3 positives
Y-1Cr-1*p^r*q^(y-r)
Y-1 = 11-1 = 10
r-1 = 3 -1 = 2
10C2 x 0.3³x0.7⁸
45x0.027x0.05764801
= 0.070
This is the probability that 11 employees must be tested to get 3 positives.
<u>Answer:</u>
25 weeks will Toby and Marcus have the same number of stamps
<u>Explanation:</u>
No of stamps collected by Toby initially= 10
No of stamps Toby collects every week= 4
No of stamps Marcus has initially= 60
No of stamps Marcus collects each week=2
Suppose the no of week when Toby and Marcus have the same number of stamps are x
Hence no of stamps collected by Toby after x weeks
=10+4x
No of stamps collected by Marcus after x weeks
=60+2x
Therefore to calculate the same of stamps collected by Toby and Marcus
No of stamps collected by Toby after x weeks= No of stamps collected by Marcus after x weeks
10+4x =60 +2x
4x-2x= 60-10
2x=50
x=25
Hence after 25 weeks Toby and Marcus will have the same number of stamps
Step-by-step explanation:
10 2/3 + 3 1/3 = 10 + 3 + 2/3 + 1/3 = 13 + 3/3 = 13 + 1 = 14
