Answer: (D) The external validity of the study
Explanation:
The external validity is the type of study which basically depicts that the concept of the study result must be meaningful. The external validity mainly apply in the conclusion in the scientific concepts and study about the main context.
External validity is the type of validity in which we extent the result of the study across the different types of situations, times and people. In mathematics, the external validity concept is applicable for determining the statistical and the various computational methods.
Answer:
Step-by-step explanation:
The formula for the circumference of a circle in terms of diameter is ...
C = πd
Then the diameter is ...
d = C/π
If we use π ≈ 22/7 and C = 66 ft, then we find the diameter to be ...
d = (66 ft)/(22/7) = (66 ft)(7/22) = 21 ft
The diameter of the pool is about 21 feet.
__
Since Carlos needs 4 more feet of rope, he will want to buy 25 feet of rope for a cost of ...
(25 ft)($0.45 /ft) = $11.25
Carlos will pay $11.25 for the rope.
Answer:
The simplification of the given expression (r3s2t)4 is:
r¹²s⁸t⁴
Step-by-step explanation:
Given expression:
(r³s²t)⁴
power of '4' on the whole term will be applied to individual terms after we open the brackets. In this case the power on the whole term will be multiplied to the power of each individual term:
= (r³)⁴(s²)⁴(t1)⁴
= r³ˣ⁴ s²ˣ⁴ t¹ˣ⁴
= r¹²s⁸t⁴
