Answer:

A = 70

Step-by-step explanation:

CB is equal to EZ and E equals 35, and E and C are the same, therefore, both E equals 35. Since there's 180 degrees in a triangle, and ABY equals 105, you have to subtract 180 - 105 to get the other angle. When you do that, you get that B equals 75. You have to add E and B (35 + 75), since that's in the same triangle as A. When you do that, you get 110. Subtract 180 - 110 to get A, which is 70.

A surgical technique is performed on seven patients. You are told there is a 70% chance of success. Use a table to find the prob

kiruha [24]

Answer:

31.77% probability the surgery is successful for exactly five patients.

Step-by-step explanation:

For each patient, there are only two possible outcomes. Either the surgery is successful, or it is not. The probability of the surgery being successful for a patient is independent of other patients. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
