The answer is 8.4 all you do is divide them together to get your answer.
Answer:
The probability that more than half of them have Type A blood in the sample of 8 randomly chosen donors is P(X>4)=0.1738.
Step-by-step explanation:
This can be modeled as a binomial random variable with n=8 and p=0.4.
The probability that k individuals in the sample have Type A blood can be calculated as:

Then, we can calculate the probability that more than 8/2=4 have Type A blood as:

Answer: 2.1 Pull out like factors :
6s - 2r = -2 • (r - 3s)
Equation at the end of step
((0-(9•(6s-4r)))+3s)--14•(r-3s)
Pulling out like terms
4.1 Pull out like factors : 6s - 4r = -2 • (2r - 3s)
Equation at the end of step
((0--18•(2r-3s))+3s)--14•(r-3s)
Final result :
<u>50r - 93s</u>
Answer:
it's SAS. You've probably found out by now sorry :/
Step-by-step explanation:
Answer:
A) The graph of f(x) = x2 is made narrower.
Step-by-step explanation:
The transformed graph has equation:

To see the transformations clearly, we need to rewrite the function in the vertex form:



Therefore, the graph of the original function is made narrow of the multplier, 3.
The correct answer is A
