Answer:
units.
Step-by-step explanation:
We have been given that two legs of triangle ABC measures 5 units each. We are asked to find the length of the hypotenuse.
We will use Pythagoras theorem to solve for the hypotenuse of triangle ABC.

Substituting our given values in above equation we will get,



Upon taking square root of both sides of our equation we will get,



Therefore, the length of hypotenuse of triangle ABC is
units.
Answer:
7 feet long
Step-by-step explanation:
This set up will give a right angle triangle where;
Length of the ladder is the hypotenuse = x
The distance of the ladder to the house is the adjacent = 3 feet
Angle of elevation theta = 72 degrees
Using the CAH in trigonometry identity;
cos theta = adjacent/hypotenuse
cos 72 = 3/hyp
hyp = 3/cos72
hyp = 3/0.4258
hyp = 7.05 feet
Hence the ladder is approximately 7 feet long
Answer:
Step-by-step explanation:
Given that the number of children in a household has a binomial distribution with parameters n-8 and p-50%
As per binomial definition we have

=
a) P(x=3 or 7) = P(3)+P(7) = 0.2188+0.0313=0.2501
b) P(X≤5)=0.8555
c) P(X≥3)=0.8555
d) P(x<7) =0.9648
Answer: a. statistic
Step-by-step explanation:
- Population : It is a set of all possible observations that can be made regarding a study by the researcher.
- Sample : It is finite subset of population that represents the population in the researcher's analysis.
- Population parameter : It is a value that is calculated from the entire population such as population mean , population proportion etc.
- Statistics : It is a value that is calculated from the sample taken out from population.
Since ,The group of people who took poll are representing the sample.
Therefore, 92% of those polled said that a year from now their family financial situation will be as good as it is today or better that means 92% describes a statistics.
Thus , the correct answer is a. statistic
