Answer:
5,418.2 feet
Step-by-step explanation:
Nadia is carrying out mountain climbing.
She started climbing the mountain at an altitude of 19.26 feet below the sea level.
Nadia changed her altitude by climbing a total of 5,437.8 feet from her starting position.
Therefore, Nadia's altitude at the end of her climb can be calculated as follows
= 5,437.8-19.6
= 5,418.2
Hence Maria's altitude at the end of her climb is 5,418.2 feet
Answer:
57 problems
Step-by-step explanation:
Total number of problems = 76
Percentage of problems answered correctly = 75%
The number of problems Cooper got correctly =
75% of 76
= 75/100 × 76
= 57 problems
Cooper got 57 problem correctly
Answer:
The standard error of the sampling distribution of sample mean is: 6.5
Step-by-step explanation:
We use the Central limit theorem to solve this question.
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , a large sample size can be approximated to a normal distribution with mean and standard deviation, which is also called standard error of the sampling distribution of sample mean is
In this problem, we have that:
The standard error of the sampling distribution of sample mean is: 6.5

Answer:
Step-by-step explanation:
Given
See attachment for the dimension of the block
Solving (a): Area of the front face
From the attachment, the front face has the following dimension.
The area is calculated as:
Solving (b): Area of the top and bottom faces
The top and bottom faces have the same dimension
From the attachment, the top face has the following dimension.
The area of the top is calculated as:
The area of the top and the bottom faces is:
---- because the top and bottom faces have the same dimension
