Thus this can be done in 7 ways
Total no of ways =
<u>Answer: </u>0.7083 or 70.83%
<u>Step-by-step explanation:</u>
Calculation of coefficient of determination for a regression analysis
coefficient of determination for a regression analysis = SSR/SST
Given
SST = 1200
SSE= 350
To find SSR
SSR = SST-SSE
=1200-350
=850
Therefore SSE is 850
coefficient of determination for a regression analysis = 850/1200
=0.7083 or 70.83%
This indicates that 70.83% is the regression equation.
Answer:
19 days
Step-by-step explanation:
Because they do a school show every Monday and a library show every fifth day of the weekday and weekend so all you have to do is count the days from the Monday they’re doing a show at both places but keep in mind that they do library shows on the fifth day of the weekend and weekday that’s how you get to 19
To cover the toy box 35.475 sq ft paint is needed.
Step-by-step explanation:
Given,
The length (l) of the toy box = 3.8 ft
Width (w) = 2.65 ft
Height (h) = 2.75 ft
To find the amount of paint is need we need to find the lateral surface area first.
Formula
Lateral surface of the box = 2(l+w)×h
Now,
The surface area of the box = 2(3.8+2.65)×2.75 sq ft
= 35.475 sq ft
