First, find R angle at TRS = 180-(10x+13)
then you know that total angles of a triangle is 180 so
TRS+RST+STR
180-(10x+13) + 8x+1 + 34 = 180
180-10x-13+8x+1+34 = 180
-13+1+34 = 10x-8x
22 = 2x
then x = 11
Answer:
(E). only (a) and (c)
Step-by-step explanation:
H0 : p1 - p2 = 0
H1 : p1 - p2 ≠ 0
To indicate that difference exists between the two treatments, then we must reject the null and confidence interval must show that the difference between the two treatment is significant.
In other to use confidence interval to test for significance ; Intervals which do not contain 0 implies that difference exists and hence, the difference is significant.
The interval Given by : (-0.279, -0.035) is significant as the interval does not contain 0.
The interval Given by : (0.279, 0.035) is significant as the interval does not contain 0.
The interval Given by : (-0.279, 0.035) is not significant as the interval contains 0.
Answer:
I KNOW AND I AM PUMPED
Step-by-step explanation:
We are given the following relation:
y = 4.302 x – 3.293
To solve for the mean value of y when x = 20, what we have
to do is to find for the value of y at x = 20 and the value of y at x = 0. Then
we get the average of the two values.
when x = 0
y(0) = 4.302 (0) – 3.293
y(0) = - 3.293
when x = 20
y(20) = 4.302 (20) – 3.293
y(20) = 82.747
The mean value would be:
mean y = [y(20) + y(0)] / [20 + 0]
mean y = [82.747 + (-3.293)] / 20
<span>mean y = 3.9727 = 3.97</span>
Answer:
Jack is incorrect. The correct answer is 2
Step-by-step explanation:
The question is given as:
4x-24 / (y+w) where x=5, y=3 and w= -5
Substitute values of x, y and w in the equation as;
4*5 - 24 / (3+-5)
20 - 24 / (-2)
-4 / -2 = 2
Jack's answer is 7 which is wrong. The correct answer is 2
2 is correct because you have substituted the real values of x,y and w in the expression and performed the operation right.
