Answer:
I think the answer is 100%
I thought you made it zero...
Like for this one, adding 10 on both sides.
-13 would become -3 and then you would use the Quadratic formula.
Though I may be wrong
Answer:
The given z-score of 188cm is 1.95 which means that this value is 1.95 standard deviations above mean ..
Step-by-step explanation:
First, we have to define z-score:
z-score tells us that how many SDs a value is above or below mean.
If the z-score is positive then the value is above mean and if the z-score is negative then the value is below mean.
The given z-score of 188cm is 1.95 which means that this value is 1.95 standard deviations above mean ..
Answer:
-30
Step-by-step explanation:
move and divide -3/5 to the right side
-3/5x = 18
x=18÷(-3/5)
x= -30
Answer:
1.Corresponding angles theorem
2.Linear postulate
3.By the definition of supplementary angles
Step-by-step explanation:
We are given that
is a transversal.
We have to prove and are supplementary
Proof:
1.Given that is a transversal.
We know that
<u>Reason:Corresponding angles theorem</u>
Therefore,
by the definition of congruent.We also know that, by definition, angle 3 and angle 1 are a linear pair.
Therefore, they are supplementary by linear pair postulate
By the definition of <em>supplementary angles</em>
Now, we can substitute
Then, we get
Therefore, by the definition of supplementary angles,angle 3 and angle 5 are supplementary
