Answer:
D.six-fourths of an hour
Step-by-step explanation:
(1/2) / (3/4) = 1/x....1/2 bedroom to 3/4 hr = 1 bedroom to x hrs
cross multiply
1/2x = 3/4
x = 3/4 * 2
x = 6/4 of an hr
Answer:
The Pearson product-moment correlation coefficient is 
Step-by-step explanation:
The Pearson product-moment correlation coefficient (PMCC) is a numerical value between -1 and 1 that expresses the strength of the linear relationship between two variables.When r is closer to 1 it indicates a strong positive relationship. A value of 0 indicates that there is no relationship. Values close to -1 signal a strong negative relationship between the two variables.
To find the PMCC of the following data, you must:
Step 1: Find 
, 
and 
as it was done in the table below.
Step 2: Find the sum of every column to get
Step 3: Use the following formula to find the PMCC.
![\begin{aligned}r~&=~\frac{n\cdot\sum{XY} - \sum{X}\cdot\sum{Y}} {\sqrt{\left[n \sum{X^2}-\left(\sum{X}\right)^2\right] \cdot \left[n \sum{Y^2}-\left(\sum{Y}\right)^2\right]}} \\r~&=~\frac{ 5 \cdot 974.1 - 11.6 \cdot 400 } {\sqrt{\left[ 5 \cdot 30.1 - 11.6^2 \right] \cdot \left[ 5 \cdot 32730 - 400^2 \right] }} \approx 0.9556\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7Dr~%26%3D~%5Cfrac%7Bn%5Ccdot%5Csum%7BXY%7D%20-%20%5Csum%7BX%7D%5Ccdot%5Csum%7BY%7D%7D%20%20%20%20%20%20%20%20%09%7B%5Csqrt%7B%5Cleft%5Bn%20%5Csum%7BX%5E2%7D-%5Cleft%28%5Csum%7BX%7D%5Cright%29%5E2%5Cright%5D%20%5Ccdot%20%5Cleft%5Bn%20%5Csum%7BY%5E2%7D-%5Cleft%28%5Csum%7BY%7D%5Cright%29%5E2%5Cright%5D%7D%7D%20%5C%5Cr~%26%3D~%5Cfrac%7B%205%20%5Ccdot%20974.1%20-%2011.6%20%5Ccdot%20400%20%7D%20%20%20%20%20%20%20%20%09%7B%5Csqrt%7B%5Cleft%5B%205%20%5Ccdot%2030.1%20-%2011.6%5E2%20%5Cright%5D%20%5Ccdot%20%5Cleft%5B%205%20%5Ccdot%2032730%20-%20400%5E2%20%5Cright%5D%20%7D%7D%20%5Capprox%200.9556%5Cend%7Baligned%7D)
The answer is <span>2n * (-1)^(n + 1)
</span><span>The numerator seems to be accelerated via 7 each and every time, so if it starts with the 1st term being one, it incredibly is secure to declare the nth numerator is 7^(n-a million) Likewise, the backside has a million, a million*2, a million*2*3, a million*2*3*4, and a million*2*3*4*5. This seems to be factorials, so we are in a place to declare the nth term interior the denominator is n! putting those mutually, the nth term is 7^(n-a million)/n!
</span>I hope this helped God Bless!
Answer: The area is 0.375 and the perimeter is 3.5
Step-by-step explanation:
The formula to find the area of something is length x width. So you have to multiply 1.5 x 0.25 which equals 0.375.
The formula to find the perimeter of something is length + width + length + width. (basically you have to add up all of the sides). I'm assuming the shape is a rectangle which means 2 sides have a length of 1.5 and the other 2 sides have a width of 0.25. So that means you would have to add 1.5 + 1.5 + 0.25 + 0.25 which equals 3.5
