3.t^2.square root of 7
Te difference of 2 standard deviation of a population n1 & n2 is given by the formula:
sigma (difference)=√(sigma1/n1 + sigma2/n2), Plug:
sigma(d)= √(49/100 + 36/50)
Sigma(d=difference) =1.1
Answer:
Step-by-step explanation:
Given is the hexagonal pyramid.
We know the radius of the base is same as its side.
<u>Find the base area:</u>
- A = 3√3/2a²
- A = 3√3/2*6² = 54√3
<u>Given the height and radius, find the side of the lateral triangular faces:</u>
Each of 6 triangles have sides 10, 10 and 6 units.
<u>Find the area using heron's formula:</u>
- s = P/2 = (10*2 + 6)/2 = 13
- s - a = s - b = 13 - 10 = 3
- s - c = 13 - 6 = 7
<u>Total surface area:</u>
Correct choice is B
Answer:
A
Step-by-step explanation:
<u>Answer:</u>
- Greatest number: 98750
- Least number: 5789
<u>Explanation:</u>
<em>To find the greatest number with the following values, we must arrange the numbers in descending form. </em>
<em>=> We can clearly tell that the numbers in descending form is 9 > 8 > 7 > 5 > 0</em>
<u>Hence, the greatest number with the following numbers (5,0,8,9, and 7) will be 98750.</u>

<em>To find the least number with the following values, we must arrange the numbers in ascending form.</em>
<em>=> We can clearly tell that the numbers in ascending form is 0 < 5 < 7 < 8 < 9</em>
<u>Hence, the least number with the following numbers (5,0,8,9, and 7) will be 5789</u>
