Answer:
<em>YES</em>
Step-by-step explanation:
To see if it is a right triangle, find the relationship using:
_
If the sum of a and b squared is equal to c (the Pythagorean theorem) then it is a right triangle.
Insert the values, with the biggest number being c (this is because c represents the hypotenuse, and the hypotenuse is the longest side of a triangle):
_
Simplify exponents:
_
Simplify addition:
_
Find the relationship:
It is a right triangle.
Finito.
Answer:
60500
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
= [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 4 and d = 7 - 4 = 3, thus
= [ (2 × 4) + (199 × 3) ]
= 100(8 + 597)
= 100 × 605
= 60500
Answer:350
Step-by-step explanation:70x500 divide by 100=350
In systematic sampling, individuals are selected at regular intervals from the sampling frame.
<h3>How to explain the sampling?</h3>
Stratified sampling- In this method, the population is first divided into subgroups (or strata) who all share a similar characteristic
<u>Clustered sampling.</u>- a clustered sample, subgroups of the population are used as the sampling unit, rather than individuals. The population is divided into subgroups, known as clusters, which are randomly selected to be included in the study
<u>Simple random sampling. </u>-In this case each individual is chosen entirely by chance and each member of the population has an equal chance, or probability, of being selected.
Quota sampling--This method of sampling is often used by market researchers. Interviewers are given a quota of subjects of a specified type to attempt to recruit.
