Answer:
The angle that the ramp forms with the ground is 27.5°
Step-by-step explanation:
Check the attachment for the figure.
Using the SOH CAH TOA trigonometry identity
For TOA
Tan(theta) = opposite/adjacent
Given opposite = 1.3m(side facing the angle of inclination
Adjacent = bottom of the ramp= 2.5m
Tan(theta) = 1.3/2.5
Tan(theta) = 0.52
theta = arctan0.52
theta = 27.5°
Cody chose a because It was the first answer though
Answer:
i would love to come but what time. i have Houston time.
and i am going to 8th grade but i would love to learn more about 7th because i am in summer school.
Step-by-step explanation:
It is very important to read the question carefully. There is chance of being mistaken with the way it has been represented. Also most of the information's required for getting to the solution is already given in the question. Based on those information's the answer to the question can be easily deduced.
Cost of each pound = $3.50
Then
The cost of 8 pounds = (8 * 3.50) dollars
= 28 dollars
So the cost of 8 pounds comes out to be $28. I hope there is nothing much complicated about the process and it is understandable.
Answer:
By the Central Limit Theorem, the distribution of ¯ x is approximately normal with mean 187 and standard deviation 2.05.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
The lengths of adult males' hands are normally distributed with mean 187 mm and standard deviation is 7.1 mm.
This means that
Suppose that 12 individuals are randomly chosen.
This means that
What is the distribution of ¯ x?
By the Central Limit Theorem, the distribution of ¯ x is approximately normal with mean 187 and standard deviation 2.05.
