Answer:
thats what she said
Step-by-step explanation:
Answer:
test statistic, z = −1.74
Step-by-step explanation:
given data
students n = 100
mean time x = 41.13 seconds
σ = 5
we consider µ = 42
solution
we get here The test statistic that is express as
test statistic, z = ......................1
put here value and we will get
test statistic, z = \frac{41.13-42}{\frac{5 }{\sqrt{100}}}
test statistic, z = −1.74
Answer:
Step-by-step explanation:
Given that:
and
To find:
Solution:
First of all,we have cos value as negative and tan value as positive.
It is possible in the 3rd quadrant only.
will lie in the 2nd quadrant so will be negative again.
Because Cosine is positive in 1st and 4th quadrant.
Formula:
Here
But as we have discussed, will be negative.
So, answer is:
Answer: and
Step-by-step explanation:
Since, here
And we know that
So
Thus,
Now, we know that
Thus,
Answer:
L(2,4) M(3,1) N(0,4)
