270,000 i’m not sure tho, you might need to be a lil more precise
0.25f< 3
0.25 * 8 < 3
0.25 * 8=2
2 < 3
So true.
If your trying to graph this is an incorrect equation for this..
Hope this helps!! If so please mark brainliest and rate/heart to help my account if it did!!
Answer: We reject the null hypothesis and conclude that the treatment group has errors that vary significantly more than the errors of the placebo group.
Step-by-step explanation:
Null hypothesis : Var1 = Var 2
Alternative hypothesis : Var1 > Var 2
The F test statistic is the ratio of squared sample standard deviation:
F= (2.4)^2 / (0.75)^2 = 5,76/ 0,5625 = 10.24
Now we have to get the critical from the F table with degrees of freedom ( n1-1,n2-1)=(23,23) :
From the F table ,F(0.05) = between 2.0050 and 2.0476 .
General rule : if the value of the test statistic is in a rejection region . Reject We reject the Null hypothesis .
F= 10.24 > 2.0476 . Therefore we reject the null hypothesis .
Conclusion: The errors of the treatment group vary more than the error of the placebo group .
Answer:
x = 4
option C)
Step-by-step explanation:
Triangle TSQ and QSR are congruent by considering HL congruency (Hypotenuse and leg of a right) which is that if hypotenuse SQ and one corresponding leg TQ and QR are equal in both triangles then both triangles are congruent.
so there corresponding angles will also be equal
<h3>2x + 13 = 21</h3>
2x = 21 - 13
2x = 8
x = 8/2
x = 4
Answer:
m∠U = 103° and m∠TRS = 6°
Step-by-step explanation:
In the given circle O,
Since, RS║VU, and VR is a transverse,
Therefor, m∠V + m∠R = 180° [Consecutive interior angles]
m∠R + 103° = 180° [m∠R = 103° given]
m∠R = 180° - 103°
m∠R = 77°
Since m∠R = m∠VRT + m∠TRS
77° = 71° + m∠TRS
m∠TRS = 77° - 71° = 6°
Quadrilateral RTUV is a cyclic quadrilateral.
Therefore, m∠U + m∠R = 180°
m∠U + 77° = 180°
m∠U = 180° - 77° = 103°
