Answer:
The angles do not have the same reference angle or the same sign.
Step-by-step explanation:
Given:
Statements related to the angle and the quadrant.
To Find:
Which statement gives best explanation
Solution:
Statements are follows:
1)The angles dont have same reference angle:
This statement is not totally true because some angles may have same reference angle . i.e depending upon the quadrant reference angle are founded .
2)Tangent is positive in second quadrant and negative in 4th quadrant:
Above half statement is false because tangent is positive in 3rd and 1st quadrant and negative in rest of quadrant.
3)Tangent is negative in 2nd quadrant and positive in 4th quadrant :
Similarly it is half negative as tangent is positive in 3 and 1 quadrant only.
4)The angles dont have same reference angle or the same sign.
This statement is true in terms of sign because reference angle will not have same sign .this gives best explanation.
f(x)=3x^2-18x+10
a = 3, b = -18 and c = 10
The vertex of a parabola is in form a(x+d)^2 + e
d = b/2a = -18/2(3) = -18/6 = -3
e = c-b^2/4a = 10 - -18^2/4(3) = 10-27 = -17
Now the vertex form of the parabola becomes 3(x-3)^2 -17
Use the vertex form of the parabola in the vertex form of y = a(x-h)^2 +k
Where a = 3, h = -3 and k = -17
Now you have y = 3(x-(-3))^2 +(-17)
Simplify: y = 3(x+3)^2 -17
The vertex becomes the h and k values of (3,-17)
The next Numbers in the pattern is 40,41
Answer:
Step-by-step explanation:
To be able to draw a conclusion from the data given, lets find out the p value using the t score and this will be used to make a conclusion.
If the p value is less than 0.05 then, we will reject the null but if otherwise we will fail to reject the null.
Using a p value calculator with a t score of 2.83, significance level 0.05 and the test is a two tailed test, the p value is 0.004655 which is less than 0.05 and the result is significant.
This we will reject the null hypothesis H0:p∗=1/2 for this data set.
