Step-by-step explanation:
flip the 2x to the other side of the ( = )
y=8-2x
Divide by Y
y=-2x+8
slope: -2x
y-intercept: 8
Answer:
a) P(Y=10)=0.0013
b) P(Y≤5)=0.00000035
c) Mean = 17.5
S.D. = 2.29
Step-by-step explanation:
We can model this as a binomial random variable with n=25 and p=0.7.
The probability that k students from the sample are foreign students can be calculated as:
a) Then, for Y=10, the probability is:
b) We have to calculate the probability P(Y≤5)
c) The mean and standard deviation for this binomial distribution can be calculated as:
