The diameter is twice the radius (D=2R), then
Answer:
A.115 students I think
Step-by-step explanation:
To get from 54 percent to 100 percent, we have to first divide by 54 to get 1 percent and then times 100 to get 100 percent. Since this is an equivalent ratios problem, we do the same thing to the other side, divide 62 by 54 and then times by 100. We should get 114.814815 which we can round up to 115. Hopefully that helps you.
Answer:
The correct option is;
A. A set of nine data pairs with a correlation coefficient r = -0.4
Step-by-step explanation:
In statistical analysis, it is important to make use of an adequate sample size in order to arrive at a valid result. An analysis with a very small sample size can provide misleading results
When performing regression analysis it is generally accepted by researchers that each variable should have at least 10 observations.
Therefore, the data set having nine data pairs with a negative correlation of -0.4 will provide the most valid result that can then be used for generalization about the larger statistical population.
Answer:
x = -4/3 and x = 5/2.
Step-by-step explanation:
6x² - 7x = 20
6x² - 7x - 20 = 0
To solve this, we can use the quadratic formula to solve this.
[please ignore the A-hat; that is a bug]
In this case, a = 6, b = -7, and c = -20.
= 
= 
= 
= 
= 
= -8 / 6 = -4 / 3
= 
= 15 / 6 = 5 / 2
So, x = -4/3 and x = 5/2.
Hope this helps!
Its 37.8 ft cuz you devide 756 by 20 and count how many 20s you used
