Answer: 2n-1
Step-by-step explanation:
If n is the larger number, than the smaller number is n-1, because they are consecutive. So if you add them together, the answer is n+n-1= 2n-1.
Answer:
1. a^3/6 (15)^{1/2}
2.
a. a = 12 cm
b. V = 384 cm^3
Step-by-step explanation:
1. The volume of rectangular pyramid is given by:
b: base area = a^2
h: height
c: side edge = 2a
"h" can be calculated by using the Pitagora's theorem:
The, the volume is:
2.
a. The side base is calculated by using the Pitagora's theorem again:
b. The volume is given by:
Answer:
If all the 300 students were surveyed, 220 would have been in favor of the photo booth.
Step-by-step explanation:
Sample size = 15
People out of 15 in favor of photo booth = 11
Percentage of people in favor of school dance =
We have to find if all 300 students are surveyed how many will be in favor of photo booth. Remember that, the sample data is the best estimator of the population data. So, the sample data of 15 students will be the best estimator for the entire population of 300 students.
Since, in the sample of 15 students, were in favor of photo booth, we would expect that if all the 300 students were surveyed, the same percentage will be in favor of photo booth. So we need to calculate of 300.
This means if all the 300 students were surveyed, 220 would have been in favor of the photo booth as per the sample data.
Answer:
D. 56.3 cubic units
Step-by-step explanation:
To find the volume of a rectangular prism you use the formula <u>v=l*w*h</u> which means you multiply <u>5*3*3.75</u> to find your answer of 56.3 cubic units.
