Answer:
There is no difference as per statistical evidence.
Step-by-step explanation:
We calculate t statistic from the formula
t =difference in means/Std error of difference
Here n1 = n2
t = (x bar - y bar)/sq rt of s1^2+s2^2
Let treatment I =X = 34 41 38 29
Treatment II Y = 39 48 35 36
X Y
Mean 35.50 39.50
Variance 81.00 105.00
H0: x bar = y bar
Ha: x bar not equal to y bar
(Two tailed test at 0.05 significant level)
N1 = 4 and N2 = 4
df=N1+N2-2 = 6
s1^2 = 81/3 =27 and s2^2 = 105/3 = 35
Std error for difference =
t = -1.02
p =0.348834
p>0.05
Since p value >alpha we accept null hypothesis.
Hence there is statistical evidence to show that there is no difference in the mean level of scores.
If f(x) = (2x+9)^3, f '(x) = 3(2x+9)^2*(2), or f '(x) = 6(2x+9)^2. Here we used the power rule with chain rule to find the derivative.
Answer:
x=70
Step-by-step explanation:
Because these angles are on the opposite sides of each other, they have to add up to 180. This will make the equation 2x-5+45=180. Simplify this to get 2x+40=180. Subtract 40 from both sides to get 2x=140. Divide each side by 2 to isolate x. x=140/2. Simplify this to get x=70.

The first thing you would do is divide 34 by 3, which is how many feet are in a yard, After you get your quotient, you will have a remainder, which will be your feet! Let me know if you have any questions!
Answer:
Angle DOC
Step-by-step explanation:
Since angle AOC and angle DOC are ajacent angles that form a straight line, they are supplementary to each other.
By the definition of supplementary angles, you can determine that angle AOC + angle DOC = 180.
Also notice that angle DOC is a right angle (90 degrees), so you can also determine that angle AOC is also a right angle since they are supplementary.
