Answer:
The diameter of the base of the cylinder is 2 cm.
Step-by-step explanation:
<u>GIVEN</u> :
As per given question we have provided that :
- ➣ Height of cylinder = 14 cm
- ➣ Curved surface area = 88 cm²
<u>TO</u><u> </u><u>FIND</u> :
in the provided question we need to find :
- ➠ Radius of cylinder
- ➠ Diameter of cylinder
<u>USING</u><u> </u><u>FORMULAS</u> :
- ➛ Csa = Curved surface area
- ➛ π = 22/7
- ➛ r = radius
- ➛ h = height
- ➛ d = diameter
<u>SOLUTION</u> :
Firstly, finding the radius of cylinder by substituting the values in the formula :
Hence, the radius of cylinder is 1 cm.

Now, finding the diameter of cylinder by substituting the values in the formula :
Hence, the diameter of the base of the cylinder is 2 cm.
Answer:
The correct option is;
D. Biased
Step-by-step explanation:
A sampling method in which the members of the sample are not representative of the population, such that some members of the population have a higher or lower probability within the sample which is indicative that not all members of the population are sampled
A biased sample is a non random sample and the can lead to misleading data conclusion
In the question, the sampling of student opinion about the school cafeteria among students who are on the lunch line and so prefer the school cafeteria leaves out the portion of the population that get their lunch from alternative sources.
Answer:
21/55
Step-by-step explanation:
dividamos por 5
= 21/55
165 new subs.
22 divided by 4 is 5.5. So approximately 5.5 new subs per day. Multiply that by 30 is 165
Answer:
The correct option is (D).
Step-by-step explanation:
Percentiles are statistical measures that are used to interpret data. It represents the data value which is more that a specific percentage of the data set.
The <em>n</em>th percentile of a data set is the value that is more that <em>n</em>% of the data set.
⇒ It is provided that a test-taker's score was at the 94th percentile for their verbal grade.
This statement implies that the test taker scored a mark more than 94% of the other test-takers, i.e. he\she performed better than 94% of the other test-takers in the verbal grade.
⇒ Also the test-taker's score was at the 16th percentile for their quantitative grade.
This implies that the test taker scored a mark more than 16% of the other test-takers, i.e. he\she performed better than 16% of the other test-takers in the quantitative grade.
Thus, the correct option is (D).
