Answer : The measurement of a central angle is, ![140^o](https://tex.z-dn.net/?f=140%5Eo)
Step-by-step explanation :
Formula used for angle subtended by an arc is:
![s=\frac{\pi r\theta}{180}](https://tex.z-dn.net/?f=s%3D%5Cfrac%7B%5Cpi%20r%5Ctheta%7D%7B180%7D)
where,
s = arc length = ![\frac{7}{3}\pi m](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B3%7D%5Cpi%20m)
r = radius = ![\frac{diameter}{2}=\frac{6m}{2}=3m](https://tex.z-dn.net/?f=%5Cfrac%7Bdiameter%7D%7B2%7D%3D%5Cfrac%7B6m%7D%7B2%7D%3D3m)
Now put all the given values in the above formula, we get:
![s=\frac{\pi r\theta}{180}](https://tex.z-dn.net/?f=s%3D%5Cfrac%7B%5Cpi%20r%5Ctheta%7D%7B180%7D)
![\frac{7}{3}\pi=\frac{\pi \times (3)\times \theta}{180}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B3%7D%5Cpi%3D%5Cfrac%7B%5Cpi%20%5Ctimes%20%283%29%5Ctimes%20%5Ctheta%7D%7B180%7D)
![\theta =140^o](https://tex.z-dn.net/?f=%5Ctheta%20%3D140%5Eo)
Thus, the measurement of a central angle is, ![140^o](https://tex.z-dn.net/?f=140%5Eo)
Answer:
The first table because the y side is increasing at the same rate . the rate is 4
Answer:
b
Step-by-step explanation:
By definition, when a test or technique measures what it intends to, it is valid.
The answer is option A.
The criterion-related validity of a take-a-look is measured by the validity coefficient. Its miles said as a number between zero and 1.00 that indicates the significance of the relationship, "r," among the take a look at and a measure of task overall performance (criterion).
Reliability and validity are both approximately how nicely a technique measures something: Reliability refers to the consistency of a measure (whether or not the consequences can be reproduced below identical situations).
Validity refers back to the accuracy of a measure (whether or not the results really do constitute what they may be speculated to a degree).
