Answer:
t-test for difference in slopes
no association exists
Step-by-step explanation:
t-test can be used to determine signifiance in difference in slopes of of fit vs time and not fit vs time graph
The data shows that as number of hours spent watchnig television increases, there is no increasing or decreasing trend in number of people fit or not fit. The number of people fit or not fit seems to be distributed around 629 for 1-2 hours of watching television. There trend is not consistent in both cases with increasing number of hours
First we look for the angle of the vector, which will be given by:
tan (x) = (- 2/3)
Clearing x we have:
x = ATAN (-2/3) = - 33.69 degrees.
Which means that the angle is 33.69 degrees measured clockwise from the x axis.
Equivalently the angle is
360-33.69 = 326.31 degrees
326.31 degrees measured counterclockwise from the x axis.
The vector is then:
v = 10 (cos (326.31) i + sin (326.31) j)
answer
v = 10 (cos (326.31) i + sin (326.31) j)
Answer:
255
Step-by-step explanation:
use calculator
we know that
shape of solar array will be rectangular
we are given
length=240ft
width =40ft
we know that
Area=length*width
............Answer
(5^1/5 b^1/5 c^1/5 d^1/5)(5^4/5 b^4/5 c^4/5 d^4/5)
5^1/5= 1 5^4/5= 125
(b^1/5 c^1/5 d^1/5)(125b^4/5 c^4/5 d^4/5)
125b^5c^5d^5
simplified: 125(bcd)^5
