Answer:
This is the answer I got
Step-by-step explanation:
JK / KL = MN / NP 6 / 4 = 18 / 12
Now u cross multiply. if both numbers are equal, they are similar. In this case, they are similar. 6 x 12 = 4 x 18
72 = 72
though the two corresponding sides of the triangles mentioned are proportional (proportionality being 1:3 ) but they need not be similar
for similarity either the third corresponding sides must be proportional or the included angle between the two proportional sides must be equal
Answer:
First answer choice
Step-by-step explanation:
Answer:
3. adjacent; 49
4. adjacent; 71
5. verticle; 41
6. adjacent; 14
Step-by-step explanation:
ok basically if the angles are next to each other, then they're adjacent and if they're across from eachother they're verticle.
to find 3:
set both equations equal to each other and solve because verticle angles are equal
to find 4:
add the 2 equations together and set it equal to 180 because adjacent angles add up to equal either a complementary angle or supplementary depending on the problem
Answer:
B
Step-by-step explanation:
Internal validity means that it it valid for the population within the study internal = study). While external validity means that it has wider applications and is valid for people outside the study or in different setting. In other word, a statistical analysis has internal validity if the statistical inferences about causal effects apply for those being studied. It has external validity when if can be generalized to other settings and populations. The answer choice which best matches this is B.
Answer choices:
A. A statistical analysis is said to have external validity if the statistical inferences about causal effects are valid for the population being studied. The analysis is said to have internal validity if conclusions can be generalized to other populations and settings.
B. A statistical analysis is said to have internal validity if the statistical inferences about causal effects are valid for the population being studied. The analysis is said to have external validity if conclusions can be generalized to other populations and settings.
C. A statistical analysis is said to have internal validity if the statistical inferences about causal effects can only be verified by a few researchers. The analysis is said to have external validity if conclusions can be verified by many researchers.
D. Internal validity and external validity are equivalent.
Answer:
The 10th term is -524,288
Step-by-step explanation:
The general format of a geometric sequence is:
In which r is the common ratio and 
is the previous term.
We can also use the following equation:
In which 
is the first term.
The common ratio of a geometric sequence is the division of the term by the term 
In this question:
10th term:
The 10th term is -524,288
