Answer:
They are: area of sector and area of triangle
Step-by-step explanation:
Area of segment=area of sector - area of triangle
So we need both the area of sector and area of triangle to calculate for the area of a segment
Answer:
Step-by-step explanation:
For testing of significance of correlation coefficient denoted by r, we create hypotheses in three ways
They are one tailed, two tailed. One tailed can be stated as right tailed and also left tailed.
The null hypothesis would normally be as r=0
Verbally we can say this there is no association between the dependent and independent variable (linear)
Against this alternate hypothesis is created as
either r not equal to 0
or r>0 or r<0
If r not equal to 0, we say two tailed hypothesis test
If r>0 is alternate hypothesis, it is right tailed test
If r<0 is alternate hypothesis, then it is left tailed test.
Answer:
the first one is 1 the second is 4
Step-by-step explanation:
these could be negatives
Hello :
q(r)=3<span>√(r²-16)
q exist : r² - 16 </span><span>≥ 0
r² </span><span>≥ 16
</span>√r² ≥ √16
but : √16 = 4 and √r² = <span>|r
|
</span>|r | ≥ 4
r ≤ 4 or r ≥ 4
the domain is : ] -∞, 4] ∪ [,4 , +
∞ [
