Answer: The digit in the thousand place is '9'.
Step-by-step explanation: The given number is 5_278.
The difference between the values of the digits in the thousandth place and the tenth place is 8930.
The digits in the tenth place is already given, which is 7
Let's assume the digits in the thousandth place is x,
Answer:
91 km per hour
Step-by-step explanation:
45 miles per hour is the same as 72 kilometers per hour (metric), so pick any value greater than 72 km per hour.
Answer:
m= 2
b=9
Step-by-step explanation:
-4, 1 -3,3
put it into y2-x2 divided by y1-x1
y2= 3
x2= 1
y1= -3
x1=-4
3-1 divided by -4--3= 2/1 =2x
get one of the points either -4,1 or -3,3
If you use -4,1 -4=x 1=y
put it into y=mx+b and you get 1= -4(2)+b simplify
1=-8+b add 8 to other side b=9
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.
