A can of beans has surface area 332 cm squared. Its height is 10 cm. What is the radius of the circular top? (Hint: The surface
1 answer:
Answer:
The radius of can is approximately 3.82 cm.
Step-by-step explanation:
We are given the following in the question:
Surface area of can = 332 square cm
Height of can = 10 cm
We have to find the radius of circular top.
Formula:
Surface area of can = Surface area of cylinder
Since, the radius cannot be negative.
The radius of can is approximately 3.82 cm.

Answer:
D. No, because the sample size is large enough.
Step-by-step explanation:
The central limit theorem states that "if we have a population with mean μ and standard deviation σ and take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately normally distributed. This will hold true regardless of whether the source population is normal or skewed, provided the sample size is sufficiently large".
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
If the sample size is higher than 30, on this case the answer would be:
D. No, because the sample size is large enough.
And the reason is given by The Central Limit Theorem since states if the individual distribution is normal then the sampling distribution for the sample mean is also normal.
From the central limit theorem we know that the distribution for the sample mean is given by:
If the sample size it's not large enough n<30, on that case the distribution would be not normal.
