Answer:
mAC=70°
Step-by-step explanation:
Someone can corroborate this but:
180°-110=70°=(m<aed)
180°-(m<aed)=70°
mAC=mBD
Answer:
2x±44
Step-by-step explanation:
-2[x-7]=-2x±14 because negative ×negative=positive
±5[3x±6]=15x±30
-3[5x±10]=-15x±30
2x±14±15x-15x±30
2x±15x-15x=2x
14±30=44
2x±44=2x±44
Answer:
Mean = 0.4
Variance = 0.24
Step-by-step explanation:
We are given the following in the question:
Possible outcomes:
X = 1(success)
X = 0(Fail)
Probability of success = p = P(X = 1) = 0.40
Since there are only two possible outcome, it follows a Bernoulli's distribution where the probability density function is given by:
The mean of distribution is:
The variance of distribution is:
