Answer:
Step-by-step explanation:
Common ratio (r) = 2nd term / 1st term = 15/3 = 5
Recursive formula:
Explicit formula:
a = first term = 3
Answer:
It’s going to be b
Step-by-step explanation:
Because add then then divide then put the x on top and simplify then and then subtract
Answer:
Step-by-step explanation:
The larger the sample size, the lower the standard deviation. The standard deviation shows how the data is spread from the mean. Therefore, benefit of increasing the sample size when trying to estimate the mean from a sample average are
a. A reduction in the bias of the estimate.
b. A reduction in the variability of the estimate.
The width of confidence interval is determined by the margin of error
Margin of error = z × s/√n
A smaller standard deviation and increased size would result to a narrower confidence interval. Therefore, increasing the sample size does not result to an increase in the width of the resulting confidence interval.
Answer:
C
Step-by-step explanation:
![y^{-\frac{4}{3}} = \frac{1}{y}^{\frac{4}{3}} = \sqrt[3]{\frac{1}{y}} = \frac{1}{\sqrt[3]{y^4}}](https://tex.z-dn.net/?f=y%5E%7B-%5Cfrac%7B4%7D%7B3%7D%7D%20%3D%20%5Cfrac%7B1%7D%7By%7D%5E%7B%5Cfrac%7B4%7D%7B3%7D%7D%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7B1%7D%7By%7D%7D%20%3D%20%5Cfrac%7B1%7D%7B%5Csqrt%5B3%5D%7By%5E4%7D%7D)
I hope I've helped you.
Use the distance formula and simply substitute in the corresponding orders pairs.
Distance = √(x2 - x1)² + (y2 - y1)²
Distance = √(4 - (-6))² + (3 - (-1))²
Distance = √(4 + 6)² + (3 + 1)²
Distance = √(10)² + (4)²
Distance = √100 + 16
Distance = √116
Distance = 10.7703296143
Round to the nearest hundredth!
Distance ≈ 10.77
