∠T
∠ETC
angle 3 with vertex e. one ray has point t on it. the other ray has point c on it.
The other ways to name ∠3 are Angle CET, Angle E, Angle TEC or ∠CET, ∠E, and ∠TEC options (B), (D), and (E) are correct.
When two lines or rays converge at the same point, the measurement between them is called a "Angle."
The question is incomplete.
The complete question is:
Which names are other ways to name ∠3?
Select each correct answer.
The missing figure is attached in the picture, please refer to the picture.
It is given that:
The two rays ET and EC make an angle 3.
The other ways to name angle 3 is:
Angle CET
Angle E
Angle TEC
Or
We can write the angles as:
∠CET
∠E
∠TEC
Thus, the other ways to name ∠3 are Angle CET, Angle E, Angle TEC or ∠CET, ∠E, and ∠TEC options (B), (D), and (E) are correct.

C. The teacher does not have enough information to make a conclusion about the average time on the test.
D. Her students, on average, do take the 30 minutes as the textbook company stated.
Answer:
Step-by-step explanation:
This is a normal distribution problem with a two-tailed hypothesis test. This characteristics helps to determine the hypothesis, which is the first step in a hypothesis test.
So, the null hypothesis would be: .
The alternative hypothesis would be: .
In this problem, we don't use inequality relations because the teacher performed a two-tailed test, which only have to options, equal or not equal.
In second place, we have to determine the significance level, which is 5%, this means that the two tales rejecting zones must be equal to 5%, that is, 2.5% for each tale. This significance level is a percentage that refers to the probability of the null hypothesis to reach that zone, as you can see, it's a low probability, so if the null hypothesis reaches that zone, it means that the data has significance, it's reliable.
Now, we have to calculate the z-score, which is gonna tell us if the null hypothesis can reach the rejecting zone or not. The equation to find z-value is: ; where x is the sample mean, u is the population mean, o is the standard deviation and n is the sample.
Replacing all values:
.
Hence, the z-value is -5.26, which is located in the left side of the population mean. Now, we have to use the z-table to know if the null hypothesis is rejected or accepted.
So, according to the table the probability value (p-value), for a 5% of significance level, is 0.0001. But, this is a two-tailed test, so the p-value is actually 0.0001(2) = 0.0002.
Therefore, the p-value is way lower than the level of significance 0.05, we must reject the null hypothesis, which means that there's no enough evidence to accept it. So, according with the test, the students don't take 30 minutes on the quiz, the correct answer is A.
Answer:
A. is the correct answer

The function that represents the volume of the capsule will be V = πr²h + (4/3)πR³. And the radius will be 19/30 cm.
Volume is a measurement of three-dimensional space that is utilized.
An aspirin tablet in a state of a right round chamber has a level of 2/5 cm and a radius of 1/2cm. the producer additionally wishes to advertise the aspirin in container structure. The case is to be 5/3cm in complete length, looking like a right chamber with halves of the globe connected to the two finishes.
The radius of the hemisphere is calculated as,
R = [(5/3) - (2/5)] / 2
R = 19 / 30 cm
The function that represents the volume of the capsule is given as,
V = πr²h + 2[(4/3)πR³ / 2 + (4/3)πR³ / 2]
V = πr²h + (4/3)πR³
V = π(1/2)²(2/5) + (4/3)π(19/30)³
V = 0.1 π + 0.3387 π
V = 1.378 cm³
The function that represents the volume of the capsule will be V = πr²h + (4/3)πR³. And the radius will be 19/30 cm.
