surface area of the triangular prism = 7×10 + 7.62 × 10 + 2× 0.5 × 3×7 + 3×10 cm²
=> 70 + 76.2 + 21 + 30 cm ²
=> 100 + 97.2 cm²
=> 197.2 cm² <em><u>Ans.</u></em>

Answer:
The slope of the line passing through the points (5, -5) and (7,3) is 4 . Use the slope formula to find the slope.
Answer:
a. The sampling distribution of the sample mean will have a smaller standard deviation than the population.
c. The sampling distribution of the sample mean will be skewed right.
Step-by-step explanation:
The mean refers to the average of a set of data which is the summation of all numbers in the data set divided by the number of values in the set.
Standard deviation is a measure that shows the extent to which each numbers in the data set is different form the value of the mean of a set of data.
Skewness is the asymmetry in or the degree of variation of a specific distribution from a normal distribution of a set of data. It is usually shown by using a symmetrical bell curve, and the curve is considered to be skewed when it is shifted to the right or left.
Since a sample of 5 household will result in a mean and standard deviation of expenses which are less than $38,500 and $10,500 respectively for the population, the sampling distribution of the sample mean will have a smaller standard deviation than the population, and the sampling distribution of the sample mean will be skewed right.
1. The answer is C. 7 with an exponent of 3 means that you multiply 7 by itself three times, or 7 x 7 x 7.
2. The answer is A. 19 with an exponent of 3 is the same as 19 x 19 x 19.
