3/4 is 75%
for this think of them as quarters 4 quarters is 100 %, 2 quarters is 50% so 3 quarters would be 75%
or you could just do 3 divided by 4 then times that by 100
Answer:
13.44% probabilith that at most 3 are in excellent health.
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they are in excellent health, or they are not. The probability of an adult being in excellent health is independent of other adults. 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.
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.
43% of adults questioned reported that their health was excellent.
This means that 
13 adults randomly selected
This means that 
Find the probability that when 13 adults are randomly selected, at most 3 are in excellent health.

In which:






13.44% probabilith that at most 3 are in excellent health.
Answer:
32.852
Step-by-step explanation:
Answer:
5 - (N x 15)
81 x 15 = 1215
5-1215=-1210
-1210 should be the 81st term
Step-by-step explanation:
The Area of a Trapezoid can be calculated as:
Area = 0.5 x Height x Sum of lengths of parallel sides
From the figure, we can see the height, which is the perpendicular distance between two parallel sides is 12.6 inches.
The lengths of parallel sides is 19 and 29.2 inches.
Using the values in the above formula, we get:
Area = 0.5 x 12.6 x (19 + 29.2) = 303.66 square inches
So, the correct answer is option C
