<u>Given</u>:
Given that the surface area of the cone is 54 square inches.
We need to determine the surface area of the cone that is similar to the cone three times large.
<u>Surface area of the similar cone:</u>
Let us determine the surface area of the similar cone.
The surface area of the similar cone can be determined by multiplying the surface area of the cone by 3. Because it is given that the similar cone is three times large.
Thus, we have;
Thus, the surface area of the similar cone is 162 square inches.
Answer:
- Elanor's standardized score is 1.19
- Gerald's standardized score is 0.72
- Elanor has higher score
Step-by-step explanation:
To compare Elanor's and Gerald's math scores, we need to standardize them and calculate their z-scores.
z score can be calculated using the formula
z= where
- X is the student's score
- M is the mean score of the exam
- s is the standard deviation of the exam
Elanor's standardized score is:
z(e) = ≈ 1.19
Gerald's standardized score is:
z(g)= ≈ 0.72
Since z(e) > z(g), Elanor has higher score
Given the equation;
To solve, let us multiply through by the least common multiple of the the denominator of the three fractions wich is 24;
