Answer:
B. Left sum < Trapezoidal rule value < Right sum
Step-by-step explanation:
The left sum makes use of the left endpoint of the sub-interval making it less than the right sum which makes use of the right endpoint of the sub-interval.
The trapezoidal approximation makes use of both endpoints, but has an area that is the average of the areas of the inscribed and circumscribed rectangles.
.Hence the trapezoidal rule value will be approximately equal to the average of the right sum and the left sum

Answer:
1. 0.1684 = 16.84%.
2. 0.2568 = 25.68%
3. 0.0013 = 0.13%
4. 0.0126 = 1.26%.
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they have blood that is Group O, or they do not. The probability of a person having blood that is Group O is independent of any other person, which means that the binomial probability distribution is used 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.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
45% of them have blood that is Group O
This means that
Question 1:
This is P(X = 6) when n = 16. So
So 0.1684 = 16.84%.
Question 2:
This is P(X = 3) when n = 8. So
So 0.2568 = 25.68%.
Question 3:
This is P(X = 16) when n = 20. So
So 0.0013 = 0.13%.
Question 4:
This is P(X = 9) when n = 11. So
So 0.0126 = 1.26%.
Answer:
35°
Step-by-step explanation:
ABC is a equilateral triangle and that means all of its
interior angles have the same measure and = 60°
since angle ACB is 60° the complementary of it would be 120° this is alsıo the measure of angle ACD
The measure of angle CAD is given as 25°
The measure of sum of interior angles in a triangle is equal to 180°
So the missing angle ADC is 35°
