Answer:
The geometric mean of given data is approximately 2.6051
Step-by-step explanation:
We are given the following data in the question:
1, 2, 3, 4, 5.
We have to find the geometric mean.
Formula:
Putting the values, we get,
Thus, the geometric mean of given data is approximately 2.6051
Answer:
D. 10%
Step-by-step explanation:
First divide 250 by 10 to get how many seats are in 10%.
250/10 = 25
Then, divide 225 by 25 to see what percent was taken up.
225/25 = 9
9 x 10 = 90
100 = 90 = 10
Therefore, 10% of the seats were not sold.
Answer:
5, 6, 7
Step-by-step explanation:
In order to solve for the three integers, we can assign a variable and set up an equation:
first integer: x
second integer: x + 1
third integer: x + 2
Given that 'the product of the first and third integer is 17 more than 3 times the second integer':
x(x + 2) = 3(x + 1) + 17
Distribute: x² + 2x = 3x + 3 + 17
Combine like terms: x² - x - 20 = 0
Factor: (x - 5)(x + 4) = 0
Set them equal to '0' and solve:
x - 5 = 0 x + 4 = 0
x = 5 x = -4
Since the problem asks for positive integers, x must equal 5:
first = 5
second = 5 + 1 = 6
third = 5 + 2 = 7
Well I know that 1/3 of 8 is 2.66666666667 I'm not sure the rest
