Answer: The p-value is 0.154.
Step-by-step explanation:
Since we have given that
We claim that
Null hypothesis :
Alternate hypothesis :
Population mean = 20 hours
Sample mean = 18.5 hours
Sample standard deviation = 4.3 hours
Sample size n = 35
So, test statistic would be
So, the p value would be 0.154.
Hence, the p-value is 0.154.
For cosФ×sinФ =0, then either cosФ or sin Ф must be zero.
cos 90 = cos 270 = 0
sin 0 = sin 180 = sin 360 = 0.
So, the values that would give you 0 are:
1. cos 90 sin Ф
2. cos 270sin Ф
3. cos Ф sin 0
4. cos Ф sin 180 and
5 cos Ф sin 360.
Answer:
Step-by-step explanation:
Slope = change in value of y on the vertical axis / change in value of x on the horizontal axis
change in the value of y = y2 - y1
Change in value of x = x2 -x1
y2 = final value of y
y 1 = initial value of y
x2 = final value of x
x1 = initial value of x
8) The line passes through (- 4,5) and (1,1),
y2 = 1
y1 = 5
x2 = 1
x1 = - 4
Slope = (1 - 5)/(1 - - 4) = - 4/5
9) The line passes through (0, 0) and (- 1, 3),
y2 = 3
y1 = 0
x2 = - 1
x1 = 0
Slope = (3 - 0)/(- 1 - 0) = 3/- 1
Slope = - 3
10)The line passes through (5, 3) and (- 2, -4),
y2 = - 4
y1 = 3
x2 = - 2
x1 = 5
Slope = (- 4 - 3)/(- 2 - 5) = - 7/- 7
Slope = 1
Answer:
13.5 i think
Step-by-step explanation:
You multiply 1/2*base*height which is 1/2*4.5*6.That is equal to 13.5
hope this helps:)
