If n is an integer, then cos(n(2<span>π))=1.
Take n=0, cos(2</span>π)=cos(0)=1, n=1, cos(2π)=1, n=2, cos(2(2π))=cos(4<span>π)=cos(0)=1...
If n is not an integer, well, ..... we don't know the value, which depends on the value of n.</span>
The projectile will be about 5.8 meters away from the launch pad.
This is an example of a quadratic equation. Imagine a arch going up and then coming back down.
This is the path of the projectile. All we need to do is find the points when the arch is on the ground. In other words, when the equation is equal to zero.
You can do this with the quadratic equation. Just plug in A = -5, B = 24 and C = 30 and you will get the answers 5.8 and -1.
The negative answer doesn't make sense here, so the correct distance is 5.8.
Answer:
(a)- Let the time in minutes of the phone call on mortality to parents be Tm and time in minutes of the phone call on dental pain be Td.
Null hypothesis:
Tm = Td
Alternate hypothesis:
Tm > Td
t-stat = (diff in means - 0)/std devn of diff in means
= -1.26
p-value = 0.74
(b)- Generic conclusion is donot reject null hypothesis as the p-value is greater than 0.05.There is no
difference in the means between the 2 groups.
(c)- In the context of the problem, the conclusion is there is no difference in preference for mortality or dental pain related calls.
When the actual thing is people want to talk when thinking on mortality, but the predicted is there is no difference.
Then we are committing a type Il error (falsely retaining the null hypothesis). prediction is stating
that the null hypothesis is true (there is no difference) but indeed there is difference. This is false retention or false negative.
Step-by-step explanation:
Answer:
y=-1/6x+3
Step-by-step explanation:
since the equation is y=6x-3 and its perpendicular, then the equation is
y=-1/6x+3
