Answer:
B and D
Step-by-step explanation:
There are 360° in a circle and this circle is divided into 8 equal parts. 360/8 = 45 which means that each angle is 45°. The central angle subtended by minor arc BC is 2 portions of the circle, or 45 * 2 which is 90°. The answer is B.
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:
Step-by-step explanation:
When you find the volume of prisms, you're essentially taking the area of the base and multiply it by the length, in varied orientations.
In this case, I'd start by finding the area of the parallelogram facing us.
The formula for a parallelogram's area is the same as a rectangle's:
A = b x h
In this case, h = 3 cm and b = 8 cm.
A = 24 cm²
Now, you multiple the area by the length of the parallelogram, which is 8 cm.
V = 24 cm² x 8 cm
= 192 cm³
