2 answers:
Answer: l =
Step-by-step explanation:
The slant height of a cone is given by
l =
h= 5
r = 3
Therefore :
l =
l=
l =
Answer:
The slant height is √34
Step-by-step explanation:
This problem bothers on mensuration of shapes, in particular the cone
We can solve for the slant height of a cone using Pythagoras theorem
N/B kindly see attached for your reference
Assuming all units in cm
Given data
Say that the slant height is x
Radius r= 3cm
Height h= 5cm
Applying Pythagoras theorem we have
x²=h²+r²
x=√h²+r²
Substituting our data into the expression we have
x=√5²+3²
x=√25+9
x=√34
The slant height is x=√34

Using the <u>normal distribution and the central limit theorem</u>, it is found that there is a 0.0409 = 4.09% probability that, from a simple random sample of 300 adults in the county, less than 50% would say they believe that gardening should be part of the school curriculum.
In a normal distribution with mean and standard deviation
, the z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
- After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
- By the Central Limit Theorem, the sampling distribution of sample proportions for a proportion p in a sample of size n has
In this problem:
- The proportion is of 55%, hence
- The sample has 300 adults, hence
Then, the <u>mean and the standard error</u> are given by:
The probability is the <u>p-value of Z when X = 0.5,</u> hence:
By the Central Limit Theorem
has a p-value of 0.0409.
0.0409 = 4.09% probability that, from a simple random sample of 300 adults in the county, less than 50% would say they believe that gardening should be part of the school curriculum.
