Answer:

The answer is A.

Step-by-step explanation:

When the Protractor is held up to the angle, you can see that the rays form an Obtuse angle. Looking at the point where the ray intercepts the curved part of the protractor, the number it goes through is 100⁰ ( ¨ ⁰ ¨ means ¨degrees¨).

The mean age of 5 people in a room is 40 years. A person enters the room. The mean age is now 40. What is the age of the person

ad-work [718]

Answer:

Step-by-step explanation:

5 people in the room have 5*40 = 200 years altogether

a new person is X years old.

Now 6 people have (200 + x) years altogether.

Mean age of 6 people is (200+x)/6. and it is also = 40.

So,

(200+x)/6 = 40

200 + x = 240

x = 40

A medical device company knows that 11% of patients experience injection-site reactions with the current needle. If 4 people rec

Orlov [11]

Answer: 0.6274

Step-by-step explanation:

Given: The proportion of patients experience injection-site reactions with the current needle : p=0.11

Sample size : n= 4

Let x be a binomial random variable that represents the people get an injection-site reaction.

Binomial probability formula: $P(X=x)= ^nC_x p^x(1-p)^{n-x}$

The required probability : P(x=0)

$=\ ^4C_0(0.11)^0(1-0.11)^4\\\\=(1)(1)(0.89)^4\\\\=0.62742241\\\approx0.6274$

Hence, the probability that none of the 4 people get an injection-site reaction = 0.6274
